Curb It Compost Program

Boiseans are proud of our successful composting program! 97% of eligible Boise families have a compost cart, and we compost over a third of all collected residential waste. Composting organic waste preserves space in our landfill and reduces methane emissions. Finished compost helps build healthy soils and grow more nutritious food.

Compost Collection

  • Curbside compost is collected weekly, year-round.
  • Finished compost is available for free to participating households.

Food Scrap Drop-off

Boiseans living in apartments, condos, or other multi-family communities without curbside compost service can now compost! Register now for this free pilot program and take your food scraps to a drop-off site to help turn waste into soil-enriching compost.
