Tobacco Composting: An Alternative to Burning or Landfill Composting is the purposeful biodegradation of organic matter‚ such as yard‚ food and agro-industrial waste. The decomposition is performed by micro-organisms‚ mostly bacteria‚ but also yeasts and fungi. A biodegradable material is capable of being completely broken down under the action of microorganisms into carbon dioxide‚ water and biomass. A compostable material biodegrades substantially under specific composting conditions.
