I've just been looking into these and they sound very good - our council collects garden, but not kitchen waste, and I came across these when looking for a compost bin - they seem ideal as they'll break down cooked and uncooked food, as well as meat and fish. Does anyone know if they're as good as they sound?
Hamster: Will the Green Cone attract flies? The Green Cone is a sealed unit and when properly installed emits no smells. It does not therefore attract flies. However, the eggs of fruit flies are already in the skins of many fruits and can hatch out in the Green Cone. Similarly, if food or food waste is not kept covered prior to going into the Green Cone, eggs may be laid by a house fly/blue bottle. These would also produce maggots and flies in the Green Cone. Good housekeeping is therefore important. Should flies become a nuisance they can be eradicated by using an air borne fly killer (given the enclosed space inside the Cone a little squirt kills the flies very quickly), which will not kill the bacteria. An organic product called "Flyko - fly and wasp killer" made by Agralan is recommended. This can also be obtained directly from Green Cone Ltd using the freephone number 0800 731 2572. Under no circumstances use liquid fly killer inside the cone
blueshoes, you can also put meat, fish, bread etc in, which you can't do with a normal composter - as well as cooked food, as coastalmum says. The green Johanna gives you compost. I think a wormery gives you good liquid feed, and a bokashi bin gives a sort of fermented mix which breaks down well in the ground. Haven't tried these, so have no idea.
Hurray! Have just ordered my Greencone. I am surprisingly excited about this. blueshoes, as I understand it, the Green Johanna gives compost, but the Greencone just leaks liquid into the ground, so you don't get feed you can use elsewhere, just very fertile soil around it. I'm hoping we can put ours where we plan to plant veg - just need to work out where the sunniest spot in the garden is.
