I've always composted in an old-fashioned "E" bin made from pallets, and set onto soil on the corner of the allotment. Worms and beasties get in, makes smashing compost. However SWMBO and I have finally bought a house, and an awful lot of the garden is currently concrete or slabs. It would be handy to compost all our home waste at home - can I simply set a plastic composter up on the slabs, or are there good reasons why I shouldn't (wind, rats, leakage, etc?).
Thanks!
