Wood, wire or plastic? Here are the different types of composting bins, and their pros and cons.

Traditional wooden bin

The classic compost bin is a wood-framed box, homemade and typically three feet cubed, though some compost gurus prefer a four-foot cube, which will handle exponentially more material.

Variations abound: One option is a hinged lid, another is a system of front slats that can be removed for easier turning. Some have lids, and others have front sections with stacked slats. Two such bins placed a few feet apart essentially make a third, perfect for a three-bin array to receive compost at different stages of preparation.

Pros: Relatively inexpensive as a do-it-yourself project and can be made rodent-proof.

Cons: Needs a flat site and may be too large for small yards. Wire-sided versions will dry out quickly in summer. Requires carpentry skills and tools.

Wire enclosure


This can be as basic as a ring of poultry wire supported by metal fence stakes, or a commercial wire bin.

Pros: Easy to install, low-cost.

Cons: Pile will need watering more often. No barrier to rodents.

Municipal bin

These are floppy circles of black recycled plastic available from some area governments free or for a small fee.

Pros: Low cost. Pile turning is easily achieved by lifting the bin, placing it to the side and forking the compost into a new location.

Cons: Fast-drying and unattractive.

Enclosed plastic bins

These polypropylene containers range in size and shape but typically require mixed compost to be added through the lid. Finished compost is retrieved from a door at the bottom.

Pros: Rodent-resistant, attractive, small footprint. Good for kitchen scraps.

Cons: Can be expensive and take months to produce finished compost.

Tumblers and barrels


These plastic containers are designed to spin or turn to ease mixing.

Pros: Makes mixing easier, and the materials are critter-proof. Good for kitchen scraps.

Cons: Expensive, sometimes mechanically irksome, and may not have sufficient volume to assure hot, active composting.
