On the podcast, Hey Dude, the 90s called,
David Lasher and Christine Taylor,
stars of the cult classic show, Hey Dude,
bring you back to the days of slip dresses
and choker necklaces.
We're gonna use Hey Dude as our jumping off point,
but we are going to unpack and dive back
into the decade of the 90s.
We lived it, and now we're calling on all of our friends
to come back and relive it.
Listen to Hey Dude, the 90s called
on the iHeart radio app, Apple Podcasts,
or wherever you get your podcasts.
Hey, I'm Lance Bass, host of the new iHeart podcast,
Frosted Tips with Lance Bass.
Do you ever think to yourself, what advice would Lance Bass
and my favorite boy bands give me in this situation?
If you do, you've come to the right place
because I'm here to help.
And a different hot, sexy teen crush boy bander
each week to guide you through life.
Tell everybody, ya everybody, about my new podcast
and make sure to listen so we'll never, ever have to say.
Bye, bye, bye.
Listen to Frosted Tips with Lance Bass
on the iHeart radio app, Apple Podcasts,
or wherever you listen to podcasts.
Hey, you may have noticed this past Saturday,
you got an extra episode of Stuff You Should Know.
Yeah, that's why SK selects.
That's right, it was not a mistake,
what we decided to do here after nine plus years is,
you know, maybe you don't know
that we have 900 plus episodes,
so we're gonna start throwing out a,
well I don't wanna call it a rerun.
Well no, it's a hand selected, curated episode by us.
Yeah, a classic if you will,
that Josh will pick one out, I'll pick one out.
Might be Newsy, it might just be one of our favorites
and we're gonna run those on Saturday.
If you haven't heard it, check it out.
If you have, we'd love for you to listen again.
Sure, so check it out in your podcast feed.
It's as simple as that.
Welcome to Stuff You Should Know from HowStuffWorks.com.
Hey and welcome to the podcast, I'm Josh, the man, Clark.
There's Charles W. Chuck Bryant
and I think I neglected to say last time.
Yeah, you did.
Guest producer Noel is with us.
That's right, so if you listen to the Shroud of Turin episode
and you're like, man, that sounds great.
Yeah, that was Noel.
Thanks, Noel.
This show today, I've been replaying one of my favorite
Simpsons jokes ever, over and over in my head.
I laughed already just hearing Simpsons jokes.
It was from one of the Halloween episodes
when they did the Nightmare on Elm Street riff.
This is old, old ones, where Groundskeeper Willie
was Freddie Krueger and he turned into,
I think like a shredder or a tractor or something
and ran over people or something.
Sure.
And said, when I'm done, they're gonna need
to do a compost boredom.
Oh, wow, that is a bad joke.
Yeah, it was really good.
I mean, the Simpsons didn't get too punny,
but that was a good one.
Well, anything goes on a treehouse of horror, you know?
Agreed.
So, you know, there's a bunch of cities
that have kind of gotten woke to the idea
that we should be recycling or composting our food.
Did you know that?
Sure.
I saw a stat that said something like 40% of food
gets wasted, but I got suspicious
because I also saw that 40% of the stuff
that goes to municipal landfills or trash is food waste,
which doesn't necessarily mean it's wasted food
because I don't think you would count
like a banana peel as food waste.
Is it a box food waste?
No.
Okay, so they're not counting food packaging as food waste.
No, but I think they're counting everything
that has to do with food that could conceivably be eaten
as wasted food, which is not the same as food waste.
Okay.
The point is the legitimate stat that I saw
just about everywhere is that if you took all the garbage
that the United States throws away into a landfill,
40% of that is food waste.
And I'm sure some of it is a whole cake,
some complete moron threw a whole cake away
for no good reason.
I was on a diet.
Well, that's actually a pretty good reason,
but you know what I'm saying.
40% of all that trash is food.
The problem is you might say, well, who cares?
Trash decomposes.
That's great.
That's true.
It does decompose.
But in the landfills that the United States uses,
we make sure they're anaerobic.
Oxygen doesn't get down there.
So a whole different decomposition process takes place.
And in a landfill, in anaerobic decomposition,
methane is produced and methane is bad news.
Methane is something on the order of 70% worse.
I know there's a much more scientific way to put it,
but it's 70% better than carbon dioxide
as far as greenhouse gases go.
70% more potent, how about that?
Yeah, okay.
So you don't want methane.
If you have to choose between methane and carbon dioxide,
you want to go with carbon dioxide.
And it just so happens that if you compost food waste,
mostly carbon dioxide is produced, methane's not.
So if you're diverting this food waste from the landfill,
there's a whole bunch of different stuff you're doing.
Number one, you're saving all that 40% of the space
for actual trash so you're extending the life
of your landfills.
You're keeping all that methane from being produced.
And as if it couldn't get any better,
you are creating an amazing fertilizer
that you can use to grow a tree out of a shoe.
This fertilizer's so good.
The old shoe tree.
Sure.
Yeah, we've danced around this a lot.
We, well, you just referenced our,
and I don't like to toot around horns a lot,
but that landfill episode was great.
Landfills, and don't forget the plasma incinerator one.
Yeah.
Basically any of our waste management ones are...
Yeah, what else?
I think Gorilla Gardening we touched on this some.
And a couple of others we've mentioned composting.
And to the extent where I thought
we had done one on composting.
Not yet.
Not until about five and a half minutes ago.
And that's a guess.
So if you write into it like it was eight minutes, Chuck.
You're grounded.
So like you mentioned,
I don't think these numbers are accurate anymore,
but we generate, let's just say a lot of millions of tons,
hundreds of millions of tons of trash.
And about 25 to 30% of that is recovered
through recycling, which includes composting,
which is good.
But that number, if it was 70%, would be amazing.
Does that include composting that recycling number?
Yeah.
Oh, okay.
Yeah, if it'd be 70, it'd be great.
Yeah, and 80, why not?
Yeah, let's shoot for 90.
Well, supposedly Seattle itself has a goal
of something like 60 to 70% of all of its trash
being recycled by the end of the year.
Of course they do, because Seattle does it right.
And they actually have compulsory mandatory composting now.
You have to compost if you live in the city of Seattle.
Why don't I live there?
I don't know.
I don't know, I asked myself that a lot.
You know, Emily and I went for our two shows ago
on that lovely spring weekend.
Oh, it was gorgeous.
And we stayed extra in Seattle,
and after we were like, we're moving here, that's it.
It's a great town.
I've said it before on the show, dogs and bars.
That was all it took.
Yeah.
Dog bar tenders.
But again, Dog's Plain Poker.
Sure.
Again, it's easy to fall in love with Seattle
on a perfect weekend in April.
Yeah.
I hear it rains there a lot though.
I'd still live there.
It's a great place.
And you know what?
You may see us again this year, Seattle.
Tease, tease.
You're such a tease.
All right, so composting is great for a thousand reasons,
but one first and foremost is that it's not hard to do
and it's not expensive to do.
No.
We just want to be, and there are many different levels
of composting from big city programs
to the home farmer that takes it super seriously,
to just, if you just want to lessen the impact
a little bit on your landfill, your local landfill,
feel like you're doing the right thing
and get a little bit of nutrient-rich goodness fertilizer
to use, you can have just a little small,
little composting operation going on at your house.
Yeah, this is all you need.
Organic waste.
And we don't even mean something that is organic.
We mean organic, meaning it's composed mostly of carbon.
It was once alive at one point, right?
Yeah, and I made a poopy noise,
which you can't use poop.
No, that's night soil.
It's the opposite of what I should have done.
What's a banana sound?
That's a banana sound, right?
You need soil, you need water, you need air or oxygen.
Right.
So the organic waste is the stuff you're going to have broken down, which in this case, in
the case of a compost pile, is food.
The soil...
Well, partially.
Sure.
But no, no, it's food for the things that are in the soil.
Oh, oh.
Yes.
Right?
It's an energy source.
Yes, yes.
And nutrient source for what's in the soil.
So you add soil.
You're basically adding starter culture to the compost.
What you're doing is grabbing microbes from, say, in your yard and putting them on the
compost pile and say, dinner's on, boys.
They eat in poop.
Yes, but you don't want to poop in it.
You need a little bit of water, like you said, to keep it moist, but you don't want to keep
it over wet because microbes like slightly moist soil.
And then air, because again, again, this is really, really important, you can let your
compost pile degrade anaerobically, but it's going to produce methane, which is bad for
the environment.
Bad for your neighbors.
Bad for your neighbors.
Bad for you.
It's going to stink.
It might blow up.
Who knows?
You don't want to smoke near what's called a passive compost pile.
So you want to just introduce oxygen.
And all this sounds very complicated.
It's not.
It's hitting it with your hose.
It's...
And by that, I mean spraying water on it with your hose, just realize you can hit some
thing with your hose too.
It's like turning it over, right?
With a pitchfork.
To add oxygen.
It's as simple as that.
Yeah, it's really easy.
So what you're going to end up with the end, like we said, is really fertilizer, but it's
called humus.
Don't call it humus.
No, that's different.
That has two M's, right?
This has just one M. And those little microorganisms in there, they're going to break this stuff
down.
They're going to eat it.
They're going to poop it out.
They're going to multiply.
And there's going to be...
We'll talk about the critters a little more later, but they're going to be different critters
along the way.
They eat those critters.
Right.
Then critters that eat those critters.
Right.
And it's going to get really hot up in there.
It might steam.
Then it's going to cool back down.
It's going to get smaller.
And it's just like this little micro environment.
It is really, really neat.
There's actually a food web in there.
There's a lot of physics and chemistry that's going on.
It is very neat.
I'm fascinated by it too.
So the upshot of composting is that you're taking something and it's being broken down
into its constituent parts so that it can be reused by plants and the whole circle of
life can start over again.
Yeah.
You're sort of just accelerating the natural process of rot.
You're optimizing it.
Yeah.
There's a passive composter, which is to say, you know, lazy hippies.
You could just throw all that junk out of your window if you wanted in a big pile and
throw your some grass clippings on and throw your fall leaves on there.
Just leave it there.
And that thing will eventually compost itself.
Well, again, it'll produce methane.
You'll blow up.
Or you could, you know, you could turn it every now and then and maybe avoid that.
But no, I think that makes it an active pile.
Well, slightly active pile then.
Right.
I don't mean like every other day.
Right.
Just to avoid methane, maybe.
But that would still technically be an active pile and be a poorly managed active pile.
Yeah.
Slightly active.
Poorly managed.
So I'm serious.
That's what they call it.
I know.
Okay.
I just, we'd like to make up our own names for things.
I didn't know you were going to cease that in your nine.
I got you.
Sorry.
We'll call that the doobie pile.
Okay.
No, it's called active management.
I just wanted to make sure that we got it on the record.
So the big goal here is to reduce your waste.
They say in this article ultimately will save you tax money because your landfill won't.
I thought that was hilarious.
Yeah.
I mean, don't count on seeing any tax breaks coming anytime soon.
But that got William F. Buckley's attention.
Probably so.
So how do you do this?
Let's say you want to start composting.
There's a one, two, three, four, five step process to get this thing going.
Okay.
Well, let's talk about them.
The first thing you want to do is just pick out the place you want to do it.
All right.
Because it's, you know, it's a bit of a mess.
It doesn't have to be necessarily, but depending on your neighbors, they might be like, well,
great.
I'm glad you started an unsightly pile of kitchen rubbish in food waste that I can see
from my deck.
Thanks a lot for that.
So that's something you want to keep in consideration.
Apparently, even if you do have a very well managed active pile, what would you call that?
I'm not making out funny names anymore.
No more jokes.
I've ruined it.
It still may stink here or there.
Sure.
I'm going to kind of away from the house, but not so far away that if you're feeling
lazy, you're not going to go out and tend to it on a daily or every other day lead basis.
Yeah.
And if you have that much land that you have a compost pile a mile from your house, good
for you.
Yeah, sure.
You got some acreage.
There might be some local rules either from your HOA, heaven forbid, if you have to belong
to one of those, or maybe just your municipality might have rules and regulations.
Yeah.
So check with them first.
Sure.
That's what everyone does before they start a compost pile.
They go down to city hall and say, what tell me the rules and regulations surrounding composting
in my yard?
I think the first thing everyone does is start throwing their eggshells out the window.
Sure.
That's how it always starts.
Right.
It's like, I'm tired of these things being in my trash.
They recommend downwind, because like you said, it might stink a bit, sun is good in
a way, but you don't want it baking in the sun all day.
No, because it'll dry it out.
Remember, you want it to be kind of moist and the sunlight can actually dry it out.
So you want, apparently the best place to put it is under a deciduous tree.
Good spot.
Yeah.
Because in the wintertime, there's no leaves on the tree, so the sun's going to keep it
warm when it's cold, but during the summer, it's going to be shaded by the tree so it
won't dry out.
It's just perfect.
It is.
Deciduous tree equals love.
Wind is good to provide a little air, but you don't want it blowing, scattering the stuff
all over the place, drying it out again.
Right.
No good.
What else?
Drainage.
Don't start one in that old baby pool that you don't want to throw out.
Especially if your baby's in there.
Yeah.
You want good drainage.
Like generally you build, either build a bin, we'll talk about this stuff actually
right now.
But it's off the ground.
Sure.
It's on legs.
Yeah.
Although you can't have a pile, but generally you want to build a bin or buy a bin and those
things sit off the ground because of drainage.
That's part of it for sure.
You also want dirt rather than say like a concrete pad or something like that.
Yeah.
Don't compost in your driver.
Right.
It's not a good idea.
As far as structures go, you can, like you said, you can go buy one.
They're not very expensive from what I understand, right?
Yeah.
It depends on the size.
You can also say go buy some cinder blocks and build something like that.
Sure.
But basically you can cut compost structures into two.
There's a single bin and there's a three bin system.
So in the single bin system, you put new stuff on top, new banana peels.
This is what I think of when I think composting, you know?
Banana peels?
Sure.
Yeah.
You put new stuff on top and then you take a pitchfork or shovel or something like that
and you work it in to the compost and at the bottom of this structure, say it's open
when you're walking up to it, the finished compost will accumulate at the bottom and
the reason it accumulates at the bottom is because it's a finer grain.
And that's it.
Single bin, new stuff at the top.
Easy peasy.
Stuff that's in process in the middle, stuff that's finished in the bottom and it will
just naturally kind of separate like that.
Yeah.
And when we're talking structure like that, if you want to build one, you know, build
a wood frame and it's like got chicken wire walls and a chicken wire bottom and that
gives you the air.
And if you've got something to collect it underneath, it's going to fall, you know,
when it's small enough.
Some other stuff might fall, you may need to add it back in.
But with the three bin system, you've got, well, you've got three bins, you've got the
starter stuff, you've got the, once it starts to break down a little stuff and then you
have the more finished product and you have to actively manage that system.
Yeah.
That system sounds unnecessarily difficult.
I kind of like it.
Oh, you're a three bin guy?
Well, we're about to get into this for real.
We've been lazily composting for a while, but we're doing our whole backyard like
we're getting rid of our grass basically.
Oh yeah.
100% of it.
What are you going to do?
Compost?
Mulch and beds and plants and herbs and walking paths.
Zero escape, you're going to put cacti in and all that?
No cacti.
Though we do have a palm tree.
We've had that forever though.
There you go.
Yeah.
Just getting rid of the grass basically.
Because it takes up so much water?
Just, it's just, it's not good grass to begin with and I'm not the best about cutting it.
Lawn mowers are terrible for the environment.
Plus you don't water it enough.
You never let a quarter inch of water accumulate on the surface.
Exactly.
Yeah.
Just, and you know, it'll look nicer.
So part of this and this company that's doing it is, it's not just a landscaping company.
They're a bunch of hippies.
Oh, gotcha.
So they're designing it in such a way that it feeds itself and part of that is composting.
Gotcha.
Anyway, long way of saying we're going to start like for real composting very shortly.
Then you're going with the three bin structure?
I don't know.
I think I'm going to build it, well it's the structure Emily tells me to build.
Okay.
It's the easiest way to say it.
Gotcha.
Yeah.
But if you buy one like you were saying, there's all different kinds, just you know, look
it up online or go to a hardware store and you know, many of them will look like a big
barrel on legs and it literally turns like has a crank on it to where you can turn this
thing in circles.
It's old-timey.
So you don't have to use a pitchfork at all.
Right.
You don't have to must your hands or your hair.
It's like a bingo spinner but with banana picks.
Have you ever played bingo like legit bingo in a room with hundreds of people?
Not hundreds.
Well, more than like you and Yumi.
Yes.
Like a bingo parlor.
Is that what they're called?
Yeah.
So we've actually gone to a couple of like senior retirement homes and helped out with
bingo.
Wow.
And that's a pretty, pretty cool experience actually because-
Do you run the bingo?
Or are you just playing kind of-
I'm not qualified to run the bingo.
Right, right.
Just walk around and point out if somebody missed one that they, you know, that was called,
that kind of thing.
But do you want to talk about taking it seriously?
Do they?
Oh my God.
Do you want to be a certified bingo master to run the show?
Yeah.
And they'll like tell you to hurry up and like shout if you're not like loud enough or fast
enough or going too fast or like-
So the point is not to have fun.
No, the point is to win.
Wow.
What do they win?
They have prizes?
Yeah.
Nothing much usually.
I mean, but you can, I think like you can play bingo in casinos for thousands and thousands
of dollars.
Yeah.
Usually at old folks homes they don't, you know-
Sure.
But there's not thousands of dollar prizes like-
Honeybuns and cigarettes.
Right.
Exactly.
All right.
Well, let's take a break here after we have talked structure and we'll talk a little bit
about what you want, what kind of junk you want to throw in that pile.
On the podcast, HeyDude the 90s called David Lasher and Christine Taylor, stars of the
cult classic show HeyDude bring you back to the days of slip dresses and choker necklaces.
We're going to use HeyDude as our jumping off point, but we are going to unpack and
dive back into the decade of the 90s.
We lived it and now we're calling on all of our friends to come back and relive it.
It's a podcast packed with interviews, co-stars, friends, and non-stop references to the best
decade ever.
Do you remember going to Blockbuster?
Do you remember Nintendo 64?
Do you remember getting frosted tips?
Is that a cereal?
No, it was hair.
Do you remember AOL instant messenger and the dial-up sound like poltergeist?
So leave a code on your best friend's beeper because you'll want to be there when the nostalgia
starts flowing.
Each episode will rival the feeling of taking out the cartridge from your Game Boy, blowing
on it and popping it back in as we take you back to the 90s.
Listen to HeyDude the 90s called on the iHeart radio app, Apple Podcasts, or wherever you
get your podcasts.
Hey, I'm Lance Bass, host of the new iHeart podcast, Frosted Tips with Lance Bass.
The hardest thing can be knowing who to turn to when questions arise or times get tough
or you're at the end of the road.
Ah, okay, I see what you're doing.
Do you ever think to yourself, what advice would Lance Bass and my favorite boy bands
give me in this situation?
If you do, you've come to the right place because I'm here to help.
This I promise you.
Oh, God.
Seriously, I swear.
And you won't have to send an SOS because I'll be there for you.
Oh, man.
And so my husband, Michael.
Um, hey, that's me.
Yep, we know that Michael and a different hot sexy teen crush boy band are each week
to guide you through life step by step.
Not another one.
Uh-huh.
Kids, relationships, life in general can get messy.
You may be thinking, this is the story of my life.
Just stop now.
If so, tell everybody, yeah, everybody about my new podcast and make sure to listen so
we'll never, ever have to say bye, bye, bye.
Listen to Frosted Tips with Lance Bass on the iHeart radio app, Apple Podcasts, or wherever
you listen to podcasts.
All right, Chuck.
So we're talking what you want to throw in the pot, right?
You got your bin, either a triple, three banger, catch site, or a single.
You got your site.
You bribed your neighbor to look the other way.
Right, your neighbor, exactly, you bought a goat.
Oh, man, talking about green living.
My neighbor has goats now, like five of them.
Are they loud?
No.
Oh, that's great.
Everyone's while I hear them, but it's a joy to hear, so it's not like a rooster.
Do you wake up and look out and say, morning, Satan?
No.
Well, goat's one of my favorites, so it's kind of nice to have them around.
Are they baby goats or adult goats?
No, they're big ones.
We got them to maintain the property because she was tired of cutting.
I guess she didn't want to zero-scape it, so she bought goats.
All right.
Anyway, it's awesome.
Kitchen waste.
Josh, that's what you want to throw in there.
Well, yeah, that's the first one.
That's the one that everybody says, that's why you compost, right?
Yeah.
And yeah, banana peels.
Everybody knows that, but did you also know you can compost apple cores in orange rinds?
You can also eat apple cores.
Yeah, you believe there is no such thing as a core, right?
Yeah, it's because there's not.
Same people who leave their apple cores left over, they can compost those things.
Those are the easy ones.
You can also do coffee grounds.
Yeah, that's a good one.
Paper filters.
Throw that filter and all in there.
Okay, so let's just say I ate maybe a whole pizza to myself.
I've got a couple of napkins wadded up.
What do I do with those, Chuck?
I think you can throw those napkins in there, Josh.
Yeah.
Isn't that crazy?
It is crazy.
Newspaper.
Yeah.
Corn cobs.
If you still read a newspaper, if you get your news on the internet, throw your laptop
in there.
Watermelon rinds.
Yeah.
Seeds.
Leaves.
You know, the butt-in to the asparagus that no one cooks?
Yeah.
Throw that junk in there.
You can also do yard waste, too.
Sure.
So you've got grass clippings, which we'll talk about in a second.
We've got a couple warnings as far as grass clippings goes.
Not too much.
But let's say you're raking leaves or something like that.
Mm-hmm.
Throw some leaves on there.
Yeah.
Good crunchy brown ones.
And you can also throw trimmings from your shrubs if you trim your woody shrubs.
The key here is this, Chuck.
You want to cut all this stuff up in small bits.
Yeah, don't throw a whole corn cob in there.
You can.
No.
Your compost pile will just throw it right back out.
Yeah.
It'll just spit it right back out.
Right.
It's very funny.
It'll make a burping noise.
Yeah.
They say to shred the corn cob, I don't have a corn cob shredder.
I don't either.
I've never thought about that.
I wouldn't waste my blender blade on chopping up corn cobs.
I think the point is breaking in the little pieces.
Sure.
You can break it into little pieces, though.
Yeah, you can probably cut a corn cob up.
Yeah.
And you can also, like, you can take all this stuff and chop it.
Anything you can put in the smaller pieces, the better.
Yeah.
Because as we'll see, what you're really doing is you're not just breaking it up.
You have to look at it like what you're doing is increasing the surface area so more microbes
can work on it at once.
Yeah.
Like, if you have, I know you hate broccoli, but.
Man, I hate broccoli.
You cut the little florets off, and you've got that big green broccoli stalk.
Yeah.
Cut that thing up as small as you can.
Set it on fire.
You have patience for it, and throw that junk in there.
Yeah.
Basically, channel your inner anal chef.
Chris.
You remember him?
The anal chef?
Yeah.
Was that a real thing?
Yeah.
I'm sitting there live.
Bill Hartman.
No, I don't remember that.
The anal retain of chef.
Oh, okay.
I forgot the retain of part.
Yeah, yeah, yeah.
I remember that.
Big qualifier.
It's like, I'm going to get that.
I'm going to get that joke, mommy.
Remember the anal retain of chef?
Yeah.
I do remember that now.
He'd start to, if he was dicing green peppers, and one of them was bigger than the rest,
he'd just be like, okay, well, you want to take those chunks, and you want to put them
into a paper towel, and then you want to fold that up, and then you put that into some
aluminum foil, and you fold that up, and you put that into a paper bag, and you roll
it up, and then you staple it, and then you throw it away.
Boy, man, what a loss that was.
Ugh.
Still makes me sad.
You mentioned newspaper earlier.
If you live near the ocean, and you've got your hands on some seaweed, or some kelp,
you can rinse that stuff off, so you don't want all that salt content in there, but
it's really good and nutrient rich if you rinse that off and put it in your compost
pile.
Yeah, and it's also good for you to eat, too.
I know I sound nuts, but just eat that stuff.
What do you mean?
People eat seaweed?
It's so good for you.
Yeah.
Salt dust?
You know I eat that.
No, but like I'm building my compost bin, I can put that salt dust back in it.
How about that?
Yeah.
Pretty neat.
Circle of life, baby.
What should not you compost?
Night soil.
Which is poopy soil.
Yep.
And then it's your dog, your cat.
You don't go take a big dump of your compost pile.
No.
I know you want to.
No.
That's not good.
No.
Disease garden plants.
That's a big one.
Yeah.
Some of this stuff, though, as we'll find, doesn't quite make sense, but it's just good
to err on the side of garbage in, garbage out, except with compost.
If you put garbage, garbage in, then it's going to be really bad.
If you put good, healthy garbage in, it's going to come out as quite good.
So you don't want to put any disease plants in there.
Invasive weeds are another one, too.
Yeah, but it says you can also put weeds in there.
So I guess you just need to figure out which ones are the bad ones.
Yeah.
So, this specifically calls out Buttercup's Morning Glory and Quackgrass.
I'm quite sure that there's plenty of seeds that wouldn't survive the composting process.
Yeah.
But apparently these do.
So stay away from the Quackgrass.
Yeah.
I think that was the big mantra at Woodstock.
Sure.
It's a gateway drug.
Don't have the yellow sunshine or the Quackgrass.
Yeah, so it was the brown acid.
Which I mean, who wants brown acid, you know?
And what about, you're talking about kitchen stuff, what about meat and dairy?
Oh, okay.
That's controversial.
It is, because Emily has taken classes and they were like, no, don't use any of that.
Yeah.
That's like animal cells and fats in particular, they putrefy, they don't decompose.
The putrefaction makes some stinky stuff and I think it can also generate a lot of disease
bearing pathogens.
So, I was surprised to see this article say, yeah, put it in there.
Well, and they kind of said in this article, if you're really heavily managing this thing,
you can do it.
But I don't know, I just heard don't.
They said turn it into a slurry, which I don't want to see Freud and Rich's Blender
at home.
Mistake that slurry.
It's with corn cob leaveings on it, but he said whip it up into a slurry and as long
as it's a good, hot, actively managed pile, it won't be a problem.
I'm going to go ahead and say, I don't think you should do that.
I don't know what to do with the animal leaveings, but I don't think you should compost it.
It might make sense to you to say, hey, I have an outdoor fire pit.
I bet that would be great in my composter.
No.
Incorrect.
Although this specifically says charcoal ashes.
I think that's any kind of charred ashes.
Yeah, like burnt wood is called charcoal.
So are you sure?
Because I know what you just said was true.
But supposedly the entire Amazon basin, and I learned this from the greatest book of all
time, 1491 by Charles C. Mann.
The entire Amazon basin was a managed forest that the indigenous peoples down there had
made completely fertile and fecund by instead of slash and burn, they were using slash and
char techniques.
And there was way more carbon locked into the charred tree stumps than there was the
ashes, so it became more fertile.
So I have a question about that one.
You know, I'm going to back off of my determined stance and say, I don't know.
It would make sense if it was coal.
Like if it was coal.
Well, like charcoal briquettes because they have cement and all sorts of chemicals and
junk in them.
But if it's charred wood or wood ash, I wonder.
All right.
Somebody let us know.
Charles C. Mann, tell us.
The pesticide treated plants, you know, you know my stance on pesticides, period.
Don't use them.
You definitely don't put that stuff in there because your whole thing here is you want
to, you want a more or less organic compost pile right in the end.
And so one of the things that people love about compost is it actually is organic.
And we're going to explain how I didn't know this until we did this research, but we'll
explain how because we're going to go through the process that your compost pile undergoes
right after this.
On the podcast, Hey Dude, the 90s called David Lasher and Christine Taylor, stars of the
cult classic show, Hey Dude, bring you back to the days of slip dresses and choker necklaces.
We're going to use Hey Dude as our jumping off point, but we are going to unpack and
dive back into the decade of the 90s.
We lived it and now we're calling on all of our friends to come back and relive it.
It's a podcast packed with interviews, co-stars, friends and non-stop references to the best
decade ever.
Do you remember going to Blockbuster?
Do you remember Nintendo 64?
Do you remember getting frosted tips?
Was that a cereal?
No, it was hair.
Do you remember AOL instant messenger and the dial-up sound like poltergeist?
So leave a code on your best friend's beeper because you'll want to be there when the
nostalgia starts flowing.
This episode will rival the feeling of taking out the cartridge from your Game Boy, blowing
on it and popping it back in as we take you back to the 90s.
Listen to Hey Dude, the 90s called on the iHeart radio app, Apple Podcasts, or wherever
you get your podcasts.
Hey, I'm Lance Bass, host of the new iHeart podcast, Frosted Tips with Lance Bass.
The hardest thing can be knowing who to turn to when questions arise or times get tough
or you're at the end of the road.
Ah, okay, I see what you're doing.
Do you ever think to yourself, what advice would Lance Bass and my favorite boy bands
give me in this situation?
If you do, you've come to the right place because I'm here to help.
This I promise you.
Oh, God.
Seriously, I swear.
And you won't have to send an SOS because I'll be there for you.
Oh, man.
And so my husband, Michael.
Um, hey, that's me.
Yep, we know that, Michael.
And a different hot, sexy teen crush boy bander each week to guide you through life step by
step.
Oh, not another one.
Uh-huh.
You know what?
Life in general can get messy.
You may be thinking, this is the story of my life.
Just stop now.
If so, tell everybody, yeah, everybody about my new podcast and make sure to listen so
we'll never, ever have to say bye, bye, bye.
Listen to Frosted Tips with Lance Bass on the iHeart radio app, Apple podcast or wherever
you listen to podcasts.
All right.
I did something we rarely do, which is look something up as we're podcasting because it
just sounded lazy to be like, oh, we don't know this one.
Onzealive.com says, um, wood ashes are so strongly alkaline that it doesn't take a lot
to upset the balance in the pile and stop the processing.
You can add a very small amount of wood ash from like your fireplace or wood burning stove.
But apparently not much.
So I think, you know, like you're kind of right in that it's, it's not completely for
boating, but it sounds like too much is not a good thing.
I think that's what Freud and Rich are saying, like, don't even mess with it.
Okay.
So why bother?
Put in animal fats instead.
Well, and that's what the, the person from Gardens Alive was saying is like, it's so
little that it's not really going to make a difference.
And if you're trying to get rid of it in a different way, right, she's like, it's not
really going to matter.
But the, but it raises a great question, Chuck.
Why in the name of all things holy would it matter what the alkalinity is of your compost
pile, and I'll tell you why because it's a chemistry experiment.
It is.
It's a, it's a chemistry experiment.
It's also a biological experiment.
You have a microcosm growing there and there's actually really easy things you can do to
optimize this and basically create a Xanadu paradise for the, the microbes and primary
and secondary and tertiary consumers of this stuff that you're putting in there to break
down so that they, they just have the greatest life that any invertebrate or microbe ever
had.
All right.
Should we talk chemistry a bit and come back to just the management and stuff?
All right.
What you're really talking about here for an ideal composting scene, you need a disco ball.
Right.
And you need a proper C in ratio, which is carbon to nitrogen ratio.
And depending on how wonky you want to get, and if you want to start measuring things,
you can do that.
But from what I gather, just try and do a lot to a little, about 30 to one carbon to
nitrogen.
Right.
And, and eyeball it.
And the rule of thumb is this, if it's green and recently deceased and by green, like a,
a nice banana peel would qualify as this, right?
If it's pliable and green or, you know, again, recently deceased, it is high in nitrogen.
Right.
If it's brown and dried, it's high in carbon.
So you want to actually, when you're adding the compost, you want to just kind of layer
this stuff in about those ratios, 30 to one.
And there's actually tables, like if you're a big time into this, there are tables out
there that tell you just about exactly the carbon and nitrogen ratio in each individual
thing.
Yeah.
But what we said earlier, you want to avoid grass clippings.
This is why, because they're too high in nitrogen.
Right.
And what happens when you have too much nitrogen?
It's bad.
Right.
It makes your piles stinky.
Yeah.
That's where the methane starts creeping in?
That actually, I think, leads to ammonia gas.
Oh, okay.
Right.
So you don't have too much carbon either, Chuck.
Yeah.
Because so carbon and nitrogen, carbon is like the building block and it's an energy
source for these microbes.
Nitrogen is essentially their growth and their metabolic activity as well.
But when they have this in these concentrations, that's when they flourish.
Yeah.
And the other problem with carbon too is it just breaks down so slowly.
Well, it depends on the source.
Yeah.
That's true.
But a lot of the carbon sources, like newspaper and corn cobs and stuff like that, it's just
a much slower process.
Right.
Right.
So they have much tougher structural support in their cells.
They have structural integrity.
Exactly.
They need to have a good saying that rhymes, like if it's yellow, let it mellow, if it's
brown, flush it down.
I thought you were heading toward that.
I was just kind of like on the edge of my seat.
No.
Like if it's green.
Yeah.
That's brown.
That's brown.
Maybe there is one that we don't know.
Or maybe someone can write one, like a creative listener.
I'd love to hear it.
I'll bet we get a bunch of those.
All right.
Oxygen, if we're talking ratios.
And again, you can walk out as much as possible, but the good news is about your compost piles.
It's not like it needs to be like the oxygen that you need.
No.
Walking around to breathe.
Which is, I think, 21% in the atmosphere.
Yeah.
That's a lot of stuff going on.
It can get by these aerobic microbes at as low as 5%.
Yeah.
That's cutting it close.
That's cutting it close.
They say try to hover somewhere around 10 or up.
Right.
And how do you measure that?
You don't.
You just aerate your pile and it's fine.
By either turning it or you can do hold PVC.
And I guess that brings us kind of to the management part.
True.
You don't just sit there unless you want to have a totally passive pile and who wants
that.
You have to manage this thing either every day or every other day, turn it, like we
were saying.
Sure.
Either with a little crank, if you've got a handy little barrel unit or with a pitch
fork or they call it a composting fork in here.
Yeah.
That's pretty fancy.
It's probably the same thing in there.
It's the same thing as a pitch fork except like $50 more.
You want to water it some, but again, do you want to give watering advice?
You don't want it for me.
You don't want it to be soaking wet.
No.
It's the moist damp.
People hate that word.
So we'll say damp.
And again, I mentioned the perforated PVC pipes that can help.
It says you can avoid turning it by having those pipes.
I would still turn it.
I would too.
Just to mix it up, right?
Yeah.
But putting PVC pipes throughout your pile would make it really difficult to turn.
So.
Well, you can pull them out.
I guess you could.
Yeah.
But getting them back in is a real pain.
You can stick them back in.
Another way to get to introduce oxygen is earthworms.
Oh man.
This is where I go crazy.
Oh yeah.
We have a lot of worms on our property because there's a lot of worms in Georgia.
We did a great episode on earthworms, remember?
Yeah.
And every time I find them, I pick them up.
I show them to Emily and she immediately says, throw it in the garden.
And that's because we weren't composting heavily.
Now it's going to be thrown in the compost pile.
But these guys are great because they naturally, I may do a lot of things, but one of the things
they do is naturally aerate by just tunneling through that stuff.
Yeah.
So earthworms and then worms in general are probably the most important non-microscopic
resident in your compost pile.
Yeah.
Because they do so much.
So worms and especially earthworms and most types of nematodes, they actually go in and
like eat a lot of this stuff that's in the compost pile, a lot of the food waste, right?
Or organic waste.
And in doing so, they break it down.
And as they break it down, they make it easier for the microbes to digest themselves.
Should we start with the microbes?
Yeah.
Okay.
So again, this compost pile, when you add food waste to the pile and add soil, you're
introducing energy source to energy consumer.
Okay?
Yes.
So the base of this is microbial life, bacteria mostly.
But the bacteria go to town, they start eating this stuff, and the smaller it is, the more
surface area there is, the more the bacteria can eat.
And they actually take the nutrients out of this and use it for cellular respiration,
which is why they need oxygen, because they take oxygen and combine them with the carbon
and they create ATP, which they use as an energy source to power their cells and live
in the frolic and play, and in doing so, they create carbon dioxide.
That's right.
So as they're doing this, they're actually breaking the stuff down from what you'd recognize
as a banana peel closer and closer to that finished humus product.
Yes.
So you've got bacteria and they're a big part of it.
And depending on the phase that the compost pile is in, there will be different kinds
of bacteria in your compost pile.
Yes, and it's not just bacteria, there's fungi doing lots of work.
We mentioned nebotodes, you're going to eventually get mites in there and slugs.
You've already thrown your worms in, some millipedes doing some action, all those cute
little legs, and overall, these are known as primary consumers.
Some are.
Are all of them primary consumers?
Well, they're listed by this person.
You made this fancy chart.
So then above that, Chuck, you've got the secondary consumers.
Secondo.
And those are the predators of the primary consumers, right?
Yes.
And then you have tertiary consumers.
They're the predators of the secondary consumers.
And so you put all this together, and what you have is a food web, with microbes breaking
the stuff down, worms and stuff doing the same thing in some ways.
And then other predators, different graduated levels of predators, preying on the smaller
animals to keep their population in check and to keep everything in a perfect balance
so that it's as efficient as possible.
And eventually a great white shark comes along.
What gets me-
It eats everything.
It eats the whole pile, thanks to a sharknada.
What gets me the best part of all this to me is that if you look at the lifespan of
a compost pile from brand new to finished humus, from banana peel to humus, it forms
a bell as far as the temperature gradient goes, right?
Yeah, it's really kind of cool.
So the first stage is the mesophilic stage.
Temperatures get up to, I think, 40 degrees Celsius.
I can't remember what that is in Fahrenheit.
Yeah, we'll go with Celsius though.
So it's warmish.
And then as the cellular respiration mounts and builds and more and more bacteria are
born and start eating and carry this cellular respiration out, the byproducts are CO2 and
heat.
And heat starts to accumulate in the compost pile, so much so that it gets up to something
like 50 to 60 degrees Celsius, which is like 100 to 150 degrees Fahrenheit.
Yeah, and at this point your organisms are going to change.
You're going to have thermophilic.
These are little heat-loving critters, and they move in because it's nice and warm.
They're snowbirds, they're desert dwellers, and they like it when it's warm.
But here's the thing is you don't want it to get too hot, so you want to continue to
aerate and keep that temperature in check.
What you want is that natural bell to happen on its own.
So the mesophilic bacteria die off or they go kind of dormant as it enters the thermophilic
phase.
And then after the thermophilic phase ends, the reason it ends is because they've eaten
up all of the stuff that's there to eat, and only the hard stuff's left over.
And so the thermophiles go away, and some of the mesophiles come back, and new stuff
comes in like ectenomycetes, ectenomycetes, which are kind of like a weird fungi bacteria
cross.
And they break down like the really hard, woody, shrubby stuff.
And they finish it off.
And this third phase is called the curing phase, right?
And at the end of all of it, you have this great nutrient-rich humus, but in the middle
of that, when it gets really hot, it gets so hot, Chuck, that pathogens that can make
you sick, that can make animals sick, that can make plants sick, are actually killed
off in the phase, which is why when you get your hands on compost on humus, it's organic.
It's been basically treated naturally to rid itself of parasites, pathogens, all sorts
of bad stuff.
And all that's left is the nutrients that have been broken down in the process that
a plant can use very easily.
And again, the circle of life starts over again.
Yeah.
And I mentioned sun earlier, it can dry it out, but if it gets over 65 Celsius, it's
going to kill off so many microbes, it's going to really slow down your process.
So that's another reason you turn it, is to kind of keep, and again, don't have it direct
sunlight, but it's going to keep that temperature where it does its thing naturally.
Where you don't want to put a heat lamp on it, just want to keep it moist, turn it over
and let it do its thing.
And you might come out there on a chilly morning, there might be steam coming off of that sucker.
And dude, that's when you just like...
You go, hot dog.
Yeah.
Hot diggity dog.
And you go inside and you eat a banana, and you throw it on the pile.
Yeah.
All right, so when is it all over?
Oh, man.
I just love...
This is why I love earth science.
Yeah.
It's really amazing.
Because it's like, it requires a little bit of human management, but then you kind of
just step away and say, do your thing.
Yeah.
It's really neat.
When is it over?
Well, you can tell.
There's a few ways of being able to tell.
The temperature starts to go down.
If it's below 100 degrees Fahrenheit, it's out of the thermophilic phase.
Yes.
And it's now into the mesophilic phase.
This says that it's probably done a disagree.
I think you probably want it even cooler than that, because the longer you let it cure,
the more diverse the microbes inside are going to be, the better the soil that you use to
amend it with is going to be.
Sure.
Temperatures won't.
One of it is just eyeball it, and if it's about 50% decomposed, like if you still see
clearly a banana peel, then it's not done.
You don't want to recognize this stuff as food at this point, or an eggshell or whatever.
And is it smaller?
If it's been reduced by 50% to 75%, and it's dark brown or black and crumbly, and it looks
kind of like soil, then you're cooking with gas, as my dad used to say.
The texture?
Did you say smoother, crumbly?
What about the smell?
Well, it shouldn't stink bad at this point.
No, it should smell earthy.
And actually, one of my favorites, the Actinomycites, they are the reason that soil and dirt has
its smell.
It's those guys.
They give it its earthy smell.
Isn't that cool?
Yeah, and I think we didn't mention you know that it's doing well along the way if it stops
smelling.
Like, it doesn't just stink the whole time.
Right, and it's not going to smell earthy.
The soil that you add will smell earthy, but when you grab a handful of humus, it should
just fall through your fingers.
It should be the closer to black, the better.
And it should smell like everything associated with earth should smell like the word earth.
That's what it should smell like.
You'll understand what earth smells like.
Yeah, they said peat moss, if none of this makes sense.
Go to your local hardware store or lawn and garden center and smell the peat moss.
Exactly.
So, now that it's done, you've got your wonderfully natural fertilizer.
Use it.
Put it, spread it out in your garden, spread it out around your trees, throw it in your
yard.
Spread it around your naked body and run around your yard.
If you want to.
That's what a doobie pile will make you do, or quack grass.
Yeah, stay away from that stuff.
It's basically the easiest way to put it without getting too scientific is it's going
to make everything better.
Right.
It's going to increase soil microbes, it's going to increase nutrients and enhance them.
It's going to improve the pH and chemistry of your soil, your yard, soil structure.
And again, what you've just done is taken stuff and had it broken down into its components,
unlocked it for your plants to use.
Yeah.
So, your plants are going to say thank you, brother.
Pretty amazing.
So, some people create a lot of it and sell it, but mainly people do this to just use
around their house.
Yeah, and increasingly towns are starting to do curbside composting pick up, food waste
pick up.
Neat.
Where you've got trash, recycling bin, food waste bin.
Banana peels.
You've got banana peels, right?
That's it.
All right.
Go forth and compost.
Yeah.
If you want to know more about composting, you can type that word in the search bar at
HouseDivorce.com, Cornell actually also has a really great site about composting.
If you want to know more about the science of it.
You were very excited about that site.
We love that site.
And since I said Cornell, it's time for Listen to Mail.
I'm going to call this Child Life Specialists.
We had a couple of these that wrote in.
Remember we talked about this?
In the paint scallops.
And we kind of surmised what it was and it turns out we were right.
And by the way, we heard from paramedics, doctors, quite a few people about the worst
pain.
Yeah.
You don't want a long bone fracture.
Yeah.
Almost 100% of them said a broken femur.
It's like the worst pain you can experience.
And should we say why?
Yeah.
Go ahead.
So, several reasons, right?
We are right because apparently it's a very sensitive area, but also because without
that structure, your muscles start spasming, which just rocks the whole thing back and
forth even more.
And then in like fragmented bone, hitting nerve, and like all kinds of badness.
Yeah.
Woo.
So steer clear of that.
All right, so we heard from two, I'm going to read the one, but I'm going to shout them
both out.
Hey guys, very excited to hear you mention Child Life Specialists during your recent
episode of Pain Scales.
As a Child Life Specialist myself, I thought we'd take the opportunity to tell you a little
bit about our profession.
You are right.
Chuck, a Child Life Specialist, we help kids deal with being hospitalized.
That's really the essence of our job.
We support children and families throughout stressful situations, such as hospitalizations
using our knowledge of child development and play to facilitate coping.
Child Life Specialists provide children with developmentally appropriate education about
diagnoses and treatments, preparation and support for procedures, and opportunities
for normalization and play.
That's a great job.
Seriously.
I can't think of too many jobs that are more rewarding than that.
Seriously.
We also provide support for siblings and provide legacy building and memory making in end of
life situations.
Our profession is very rewarding.
Josh, you are right.
She predicted you would say that.
And I love going to work every day.
Become a CLS.
You must have a bachelor's or master's degree in child development or related field.
Meet a 640-hour Child Life Internship and pass a national certification exam.
You can visit www.childlife.org to learn more about it.
Thanks for what you guys do.
You've made all my road trips interesting.
Thanks for spreading the word about child life.
Maybe you can do an entire episode on our profession in the future.
She said future.
Okay.
And that is Natalie Valentine and also a big shout out to Amanda Butler from Auburn University
who does that there.
Thanks for writing in, ladies.
It sounds like just a really, really great job.
Yeah.
Thanks to you both for that.
Thanks for everybody who has anything to do with making kids who are hospitalized feel
better.
It's off to you.
