Knowra Municipal solid waste Municipal solid waste Municipal solid waste is everyday discarded material collected from households, businesses, and public institutions. It includes materials such as food scraps, packaging, paper, and discarded products.
Waste collection : The organized removal of discarded materials from homes, businesses, and public spaces. Collection systems determine which materials enter municipal waste streams and how often they are removed.
Waste hierarchy : A framework that ranks waste-prevention and management options from most to least preferred. It places prevention and reuse above recycling, recovery, and disposal.
Municipal recycling : Local-government systems that collect and process discarded materials for reuse as products or manufacturing inputs. Recycling programs divert selected materials from disposal and return them to production.
Landfill gas : A gas mixture produced when microorganisms decompose organic material in landfills, chiefly methane and carbon dioxide. Organic municipal waste generates methane as it decomposes in oxygen-poor landfill conditions.
Waste prevention : Actions that avoid generating waste in the first place. Prevention reduces the amount entering municipal collection rather than treating it afterward.
Materials recovery facility : An industrial plant that separates recyclable materials from mixed or source-separated waste. These facilities extract recyclable paper, metals, plastics, and glass from collected waste.
Waste characterization : The measurement of waste composition, quantity, and relevant physical or chemical properties. Composition studies guide facility design and reveal how much waste is recyclable or biodegradable.
Composting : The managed biological decomposition of organic material into a stable soil amendment. Separate collection can turn food and yard waste into compost instead of landfill gas.
Waste incineration : The controlled combustion of waste, sometimes combined with energy recovery. Incineration reduces waste volume but produces emissions and residual ash requiring management.
Reuse : Using a product or material again for its original or another purpose without substantial reprocessing. Reuse preserves products before they become municipal waste and require recycling or disposal.
