But the huge dumping of waste can raise some threats to life sooner or later. To avoid this, some people practice composting. In composting, the biodegradable wastes are dumped into a pit and covered for a period. Due to the action of microbes, they will decompose and will be used as manure for cultivation purpose. This will reduce the amount of waste at landfills.
Capable of being decomposed by biological agents, especially bacteria: a biodegradable material.Biodegradable waste includes any organic matter in waste which can be broken down into carbon dioxide, water, methane or simple organic molecules by micro-organisms and other living things by composting, aerobic digestion, anaerobic digestion or similar processes. In waste management, it also includes some inorganic materials which can be decomposed by bacteria. Such materials include gypsum and its prodcts such as plasterboard and other simple organic sulfates which can decompose to yield hydrogen sulphide in anaerobic land-fill conditions.
In domestic waste collection, the scope of biodegradable waste may be narrowed to include only those degradable wastes capable of being handled in the local waste handling facilities.
