Compost is organic matter that has been decomposed in a process called composting. This process recycles various organic materials (such as food waste) otherwise regarded as waste products and produces a nutrient-rich soil "conditioner." The Spokane County Regional Solid Waste System's Master Composter program teaches individuals how to successfully compost at home to reduce waste, create "black gold" for gardens and soils (a.k.a nutrient-rich fertilizer), and even save money by eliminating the need for a clean-green bin or reducing garbage can sizes.
