The Numbers

  • Americans generate about 290 million tons of trash each year.
  • More than 30% of what we throw in the trash could have been composted. 
  • Composting has been around for 12,000 years.

Composting Is:

  • For Everyone: It can be done in backyards or indoors or by giving scraps to a local organization to compost for you. 
  • Safe: Compost is safe to use in home gardens. 
  • Earth-Friendly: It reduces the amount of trash going to landfills.

How It Works:

  1. Natural waste is placed in a pile or bin. 
  2. Over time, decomposers such as bacteria, fungi, and worms break down the waste, leaving behind nutrients.
  3. Eventually, the mixture turns into a soil-like material that can be used as fertilizer. That’s compost!
