A Green Cone can take all food waste including meat, bones, fish and dairy products. The waste breaks down into water and nutrients which dissipate into the surrounding soil. They cannot take garden waste and do not produce compost.
A Green Johanna also takes all food waste including meat, bones, fish and dairy products but must have garden waste put in. It produces rich compost for the garden.
The Green Cone must go in a sunny spot, the Green Johanna in the shade.
