Mulch is defined by the Georgia Rules for Solid Waste Management as a product produced by grinding, shredding or chipping of yard trimmings, land-clearing debris, untreated and unpainted wood, or any combination thereof, that has not undergone controlled aerobic decomposition to produce a stabilized organic product. It is considered a recovered material and is exempt from solid waste regulations.

EPD encourages mulching to reduce yard trimmings and other woody materials destined for landfills. Throughout Georgia there are many uses for ground, shredded, or chipped wood, from fueling power plants to providing materials for the pulp and paper industry.
