Organic Waste

Organic waste is discarded material of biological origin, such as food scraps, garden trimmings, agricultural residues, manure and some natural fibers. Much of this material can be broken down by microorganisms, although its biodegradability depends on its composition and treatment conditions. Suitable organic waste can be processed through composting or anaerobic digestion to recover nutrients, organic matter or biogas. When biodegradable organic waste decomposes without oxygen in landfills, it can generate methane, a potent greenhouse gas.
