Landfills are the primary method of waste disposal in many parts of the world, including United States and Canada.Bioreactor landfills are expected to reduce the amount of and costs associated with management of leachate, to increase the rate of production of methane (natural gas) for commercial purposes and reduce the amount of land required for land-fills.
Biodegradable and compostable materials have been developed to ensure more of human waste is able to breakdown and return to its previous state, or in the case of composting even add nutrients to the ground. [45] When a compostable product is thrown out as opposed to composted and sent to a landfill, these inventions and efforts are wasted.
Landfill gas is a mix of different gases created by the action of microorganisms within a landfill as they decompose organic waste, including for example, food waste and paper waste. Landfill gas is approximately forty to sixty percent methane , with the remainder being mostly carbon dioxide .
Class Two landfills can accept waste that tests at less than 10 times the maximum contaminant levels. Any waste that can decay must be removed from Class Two landfills within 72 hours.
Waste management or waste disposal includes the processes and actions required to manage waste from its inception to its final disposal. [1] This includes the collection, transport, treatment, and disposal of waste, together with monitoring and regulation of the waste management process and waste-related laws, technologies, and economic mechanisms.

A landfill [a] is a site for the disposal of waste materials. It is the oldest and most common form of waste disposal, although the systematic burial of waste with daily, intermediate and final covers only began in the 1940s.
[4] [5] Composting offers an environmentally superior alternative to using organic material for landfill because composting reduces methane emissions due to anaerobic conditions, and provides economic and environmental co-benefits. [6] [7] For example, compost can also be used for land and stream reclamation, wetland construction, and landfill ...
