Composting and compost bins

About the bins

The compost bins sold by Hennepin County are made of cedar and wire mesh. Bins are sold as a kit with all materials, hardware, and assembly and composting instructions included; some assembly required. 

Kits are about 3' x 3' x 1'. Assembled bins are 3’ x 3’ x 3’.

Bins cost $50 each. Some assembly is required. Lids are available for an additional $10.

Bins are built by Sentencing to Service (STS) Homes crews, which is an on-the-job carpenter training program for incarcerated men and women.

Cities have varying backyard composting ordinances; check with your city recycling coordinator about your local ordinance.

Each city has its own ordinances about composting, so check with your city recycling coordinator for details concerning your local laws.

Add materials

Many people understand what can be composted in backyard bins but can get confused about what not to compost.

Do compost

• Yard waste, including grass clippings, plant trimmings and leaves
• Kitchen waste, including fruit and vegetable scraps, coffee grounds, tea bags and egg shells
• Small amounts of sawdust, wood chips, wood ash, and small sticks
• Non-recyclable papers: paper towels, napkins, egg cartons

Don't compost

• Meat and dairy
• Fats and oils
• Pet waste
• Weeds with seeds
• Large pieces of wood

As a general rule, add three parts of dry, brown materials to one part of wet, green materials. Brown materials include dried grass, leaves, straw, sawdust and twigs; green materials include coffee grounds, fruit and vegetable scraps, grass clippings, green leaves and plant trimmings.

Home composting systems typically don’t reach high enough temperatures to break down meat, dairy, grease and oil. These materials can also attract critters to your compost bin and cause foul odors.

Feces from pets may carry pathogens that could cause health problems.

Large pieces of wood do not compost quickly and require a lot of energy to decompose, so wood should be chipped or shredded and used minimally.

Maintain your compost pile

Follow these tips to maintain a successful compost pile:

• Keep your compost pile at the right moisture level. If your compost pile has a bad odor, it lacks air circulation or it may be too wet. Try turning the pile and/or adding dry, brown materials to the pile.
• If your compost pile is not heating up, it may need more nitrogen or "green" material. Add grass clippings to the pile.
• Bury kitchen scraps at least 8 inches deep in the compost pile to discourage critters.
• You can keep adding to your compost pile as it is composting. However, you may want to start a second pile if you have enough materials.
• Continue adding materials to your compost pile in the winter. It will thaw and continue breaking down in the spring.
• The best pile is made up of a variety of materials.
• The smaller the bits of compost material, the faster the pile will decompose.
