I built this double barrel wooden compost tumbler last October and have been filling it ever since.
9 months of food scraps, garden clippings, wheel barrows of fallen leaves, and entire lawn mower bag of grass clippings, who knows how many cardboard boxes and paper packing materials… all in ONE barrel!
I’ve never emptied it or moved on to the second barrel. No matter how much I add, it always seems to break down to be less than half a barrel (one barrel is 30 gallons capacity).
I’m sharing because I’m simply blown away by how much material it is going to take to fill these barrels. They are seemingly bottomless!

Dang you got plans for these? Nice work dude
But….how do you pee in it? Sick setup OP!
Bro got the scp for a composter lol
So I know for a fact that I’ve put over 40 gallons of scraps,. coffee grounds, and shredded paper into a space that only holds 15 gallons. I also know that when I sift/grind the fully composted material I’ll maybe have 7 gallons max.
Good looking tumbler by the way. Any issues with the insides rotting?
I want to fuc… I mean piss in this
Vegetable matter is like 90% water…
Nice!
this is an amazing bin! Where did you get the plans?!
I’m convinced of the same. I haven’t pulled up thing out of the bottom of mine in a year, and it’s never full.
Me as well and I have a double tumbler just like this except it’s plastic (ug) and easily half the volume on each side
My compost bin is made from a plastic garbage bin with holes drilled in the bottom. It’s way trashier compared to how sleek and beautiful yours is.
Question: are you in a place that sees a deep cold winter and if so does this still compost in winter for you? How often do you find your self cranking it for turn over? Did you use cedar wood to build this? 🧐 (very cool set up! I know nothing about tumbling composters FYI)
Are you blessed with black solider fly larva? Once those guys get started it’s truly like a black hole. I bought an overflow bin that I rarely get to use because the tumbler empties itself so fast.
Someone pointed out that vegetable matter is 90% water. 90% of the dry weight of green material like that turns to CO2. It came from CO2, it’s the circle of life.
The same thing happens with brown material but the cycle is slower, it takes multiple years, and a significant portion of the carbon flows into mycelial bio mass in the soil.
More browns.
