Organic waste is an important constituent of the constituent of the solid waste stream. In terms of organics recycling programs, food and yard waste are most often targeted for composting initiatives in this rapidly growing sector of the recycling industry.As can be seen in the attached image, food waste is the leading contributor to solid waste in landfills. According to the U.S. EPA, the average American throws away 1.3 lbs (.6 Kg) of food scraps daily; 475 pounds per year. In addition, when food waste goes to landfills, the end product is methane, one of the most harmful greenhouse gases.
Composting can be defined as the managed decomposition of organic materials. Along with other organic waste such as wood waste as well as paper and paperboard products, organics comprises more than two-thirds of the U.S. solid waste stream. The establishment of organics recycling programs or composting is seen in many jurisdictions as a priority in their efforts to prolong landfill life, reduce methane emissions from landfills and otherwise promote sustainability in their communities.
