Step 4: The Inside of the Wheelie Bin
The bottom of this particular bin has a very odd shape to accommodate the wheel housing at the back and a grab handle at the front. Extracting the compost at the bottom would not be easy so I fitted the Compost Base Grid above the molded wheel housing where there is also a flat side allowing a hatch to be cut out.
Using a wheelie bin with the least amount of narrowing towards the bottom of the bin will reduce the opportunity for the compost to clog. Flat sides with wheel fittings, etc., on the outside of the bin will increase the useable space inside.
