From which source can composting materials originate?

Explanation:
Composting relies on biodegradable organic matter that microorganisms can break down into nutrient-rich humus. Agricultural waste provides abundant, readily compostable material such as crop residues, leaves, grass clippings, and manure. Plastic and metal are inorganic and do not biodegrade into compost. Sewage sludge is an organic byproduct of wastewater treatment and can be composted in some systems, but it has special handling and safety considerations and isn’t the typical feedstock for standard composting. Therefore, agricultural waste is the source that best fits compostable feedstock.
