"Hot" compost bin

We’re going to be moving to a new house soon, and one of the first things I intend to do is get a compost bin. We produce an inordinate amount of food waste in our house, at least partly due to two small children who can be quite fussy eaters, so I’m looking for a compost bin that takes cooked food as well as vegetable peelings and the like (ie a digester as well as a composter).

The Green Johanna looks like it’ll do the job perfectly, and actually benefits from a mix of waste so will take our cardboard too! Plus it comes with a little coat for winter. How sweet. It’s on the expensive side, but Recycle Now shows that there’s roughly a 25% discount in my area, plus a whole pound off for shopping online.

Hi Jenni If you want your compost to work a lot faster then get yourself some composting worms. When not XMLing I am worm farming, so if you want to visit NAG during the next XML summer school I can make you a present of some 500 worms. They will even eat your cardboard, snotty tissues and pretty much anything else you would like to put in. NAG’s worms currently have a high caffeine diet of teabags and coffee granuals.

Wired worms, what a thought! Thank you very much for the offer. I really fancied using worms, but I gather they can’t digest meat — is that right?

Re: "Hot" compost bin

Being a veggie myself I have never fed the worms I have on meat and I don’t usually recommend it if you don’t have a rat-proof composter, but seeing as yours rates itself as so, then I don’t see a problem. All your waste is better chopped up, so if the meat is too then it shouldn’t be in there too long to get too smelly.

“compost bin that takes cooked food as well as” … and attracts the rats Jen? Thirty quids worth of 4 by 1 boards cross jointed into a metre square will take all the above… except the cooked stuff (well include the cooked veg if needed) and heat it nicely.

Just needs a topping of some non-foam backed carpet to keep it moist.

I don’t like rats. I do find the cats like the bin, since it gets warm though.

Re: "Hot" compost bin

It looks like it’s designed specifically to keep out the rats (as you might expect). The amount of cooked food (including meat) we throw away is shocking: I’m really after a method of composting our mostly-eaten roast chicken carcass (with apologies to the vegetarians reading this).

My ideal compost bin would harness the generated heat as well, but I’d be content for the cats to benefit from it.

Re: "Hot" compost bin

Certainly the conventional wisdom is not to put meat in compost bins because it attracts critters (and there can be an odor problem). But disposing of chicken carcasses is an interesting problem. It occurs to me that a flock of chickens might be just the ticket: chickens will eat almost anything and they’d certainly eat the meat off of a carcass. You could then dry or bake the remaining bones to grind for bone meal. Hmmm. We do give our chickens meat scraps. And you get eggs in return.

I also recommend worm bins. Everything that doesn’t go to our chickens, goes to the worms. This is mostly coffee grounds and stuff, but includes moldy bread, veggie peels and stuff that might be inappropriate for chickens or would just be too messy for the coop.

If you have ready access to horse manure, it’s easy to build a large, hot pile that you could probably put anything into and have it digested quite quickly.

Finally, I have a composter similar to the Green Cone (although not quite so fancy). I never found it to be quite as advertised, but then I may not have kept it full enough (or maybe I was insufficiently patient). I find that a simple bin kept full with grass clippings or manure works as well and the worm bin does a better job of composting the kitchen waste.

Also, worm bins can be kept indoors as they don’t smell if kept functioning correctly (that is, not too wet so that stuff doesn’t get really icky). There in England you don’t really have to worry about the heat or humidity outside but here in Texas it’s easy to either freeze or bake an outdoor worm bin.

Cheers,
