Organic waste when improperly deposited in open dumps, accumulating dirt and insects is a serious problem for the environment. In addition to the risk of leachate, if methane gas is released, manure is a contaminant agent in the water table, and methane gas is 23 times more harmful than carbon dioxide. To solve this environmental problem was created the Law of the National Solid Waste Policy (No. 12,305, August 2, 2010), which aims to end public dumps, with the replacement of landfills by sanitary landfills.
However, with this law, several municipalities have difficulty implementing landfills because of the high cost. Composting is considered a cheaper solution for the treatment of organic waste. Composting is the biological decomposition process, which aims to reuse organic waste. This process allows to give a destination to the waste, avoiding the accumulation of the same, besides being used for soil fertilization.
Composting brings broad environmental and financial benefits, we highlight these advantages:
- Composting does not release CH4 (methane gas) which is extremely harmful to the environment.
- Reduces the amount of waste destined for landfills, as a consequence, generates cost-saving landfill.
- Economics in the treatment of Effluents.
- Reutilization of organic waste, producing a quality organic fertilizer.
- Elimination of pathogens due to high temperature reached in processing.
