More About Bins: Types and building plans
Holding Units
Holding bins are designed to simply contain the compost pile, without providing easy access (a front gate) for turning the compost. Easy to set-up, low maintenance, and generally inexpensive, holding bins can take six months to two years to produce finished compost.

Wire Enclosure Easy to set up, this type of bin is easily made using a large loop of chicken wire, snow fence, or aquamesh. To empty the bin, it is simply dismantled.

Turning Units
Turning bins make it easier to turn and regularly aerate composting waste by ensuring easy access to the heap. With increased aeration, these bins can produce finished compost in a period of one month to one year.

3-Bin Units For the most demanding waste volumes, this type of unit allows for multi-stage composting. Fresh material is added to one bin, then turned and shovelled into the next bin. Finished compost is removed from the final bin. (Plans available)

Pallet Bin Bins built from used pallets also help to keep those pallets out of the waste stream, and are a preferred bin type for hard-core recyclers. By simply building a swinging gate with the front pallet, it serves well as a turning unit. (Plans available)

The New Zealander With a removable front gate and black plastic cover, this bin is a favourite of the home handyperson. Recycled wood can be used in the construction, for a unit that looks great in any backyard. (Plans available)

Rotating Barrel Bin Although more challenging to build, the enclosed bin can help where pests are a problem. Aeration is provided by simply rotating the barrel, which is easier than having to fetch a shovel or pitchfork. (Plans available)
