How to Make a Compost Toilet with a Wheelie Bin


Hi, Jeff Laughton here, and I’m making a compost toilet. Why? Because they’re extremely efficient and they don’t use any water. And a normal-flush toilet uses 30 to 40 thousand
liters per person, per year. Now we can turn our humanure into a very sustainable waste system, and it’s completely healthy. There’s no problem. There’s no problem with diseases, in a lot of A-projects, it’s an ideal solution, but it’s an ideal solution for the first world. And it can save a lot of money. I can show you how to
make a compost toilet by recycling materials
you can find anywhere in the world, and it’s really cheap. You don’t have to buy an expensive one. So, let’s show you how to do it. The first thing we have to do is actually drill a
hole right at the bottom of the wheelie bin. Then we fit an irrigation fitting and a sealing washer, put on a ball valve tap and a fit into a hose so we can open up the ball valve and drain any surplus liquid from the bin. Then all we have to do
is make our own filter. And a bit of shade
cloth tied on the inside of that pipe. That just stops it blocking. This might be a little bit tricky ’cause you’ve actually got to climb inside or crawl inside, and screw the inside of that tap on. And then fit your filter. Next, we need to measure the corners. The back corners are
shorter because they go down to the axle ledge, there. And we just need a pipe cut in half. We need to cut an ordinary
bound-pipe for plumbing. Cut it in half, then cut slots all the way along. On regular intervals, stand the pipe for aeration in the corners. Then we get ordinary strapping. We measure it around the pipe, strap it on, with pop rivets drilled straight
through the wheelie bin. Now we need to get a grill and shape it, so it fits around the pipes, on the recess of the axles, and on the elbow of the two longer parts at the front. Now we need a long piece of shade cloth, that will wrap around the grill at least once, twice. Then we fold in the edges, tuck that under the back pipes, and rest it on the elbows at the front. And we’re ready. Now, we need to get a second lid. And we need to cut a large hole in this lid, the size of the compost
toilet delivery pipe. This is a band cut out of a recycled inner-tube from the car tire depo. Who knew you should get ’em for free? This seals on the tube, and goes down onto the
lid of the compost toilet, and helps make it more or less air-tight. And the lid that’s attached to the bin is going to lock it down when it’s full so it can go through a
full moldering process. Now we just click on the garden hose and we can open the tap, and any surplus liquid can be directed to a reed bed like this if you have one. Otherwise, it can go to a gravel trench in the ground, with a slotted pipe so all the surplus liquid
just soaks to the ground and becomes a natural fertilizer. All we need to do now is tip in 20 liters of sawdust. We’re ready to start the system. Purchased systems, built systems, I’ve tried many types of
compost toilets over the years, but they all work the same. Compost is compost. This system is as good as any. And all you have to do
now, once it’s full, is lock it down. Keep it locked up for six to ten months, and then it’s ready. You just empty it and use it again. This is one of the best
systems you could use. It’s made out of recycled materials. It’s a completely waterless toilet. Uses minimum water, and it’s safe and efficient. This, I believe, is one
of the most ethical ways you can use a compost toilet with sensible materials. Here’s the end result. So this is what we can
put around our trees. It’s nice, high fungal compost. It’s got a lot of sawdust in it, or it’s got a lot of wooden material. It’s broken right down, it’s nicely aged. It doesn’t look like
anything it started off as. It’s quite safe to handle. Just looks like typical forest mulch. There we go. Put it around our tree. Pulling it back a bit. There we go, that’s humanure, when it’s gone through the process, and it’s aged really well. It smells fine. Looks fine. You wouldn’t have no idea how it started life.
