With the correct separation it is possible to use the organic material for the organic compound and the waste or residue which is not yet in the compound stage which can be returned to the process. In this way, significantly reducing the final waste or discards that will go to the organic compound.
Residues for such purposes may come a variety of areas, such as industries, rural areas, metropolitan areas, and may be contaminated or in size and shape that are not suitable for the organic compound. These materials must pass through a sieving system and sorting for the separation of impurities and wastes or products that are not yet in the phase of organic compounds.
Organic waste when improperly deposited in open dumps accumulating dirt and insects is a serious problem for the environment. Because in addition to the risk of the waste, is the release of carbon dioxide. To solve this environmental problem was created the national policy on solid waste (No. 12,305, August 2, 2010), which aims to end public waste, with the replacement of barrios by sanitation.
Meanwhile, with this law, several municipalities have difficulty implementing sanitary waste because of the high cost. The organic compound is considered a cheap solution for the treatment of organic waste. Composting is the biological decomposition process, which allows reuse of organic waste. This process allows to give a destiny to the residues, 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.
- Reduce the volume of waste destined for waste, resulting in reduction with the costs of waste.
- Economics in the treatment of tributaries.
- Reaprobe3chamiento of the organic waste, producing an organic fertilizer of quality.
- Elimination of pathogens due to high temperature that arrives in the process.
Traditionally, the material used for composting is of agricultural origin. This type of material in general is free of contaminants and, when composting happens correctly, produces organic fertilizer of good quality and suitable for use in plantations.
The process of composting in piles can be carried out in any climatic zone. Organic waste comes waste, thus reducing the emissions of gases that generate the greenhouse effect. The use of this fertilizer increases the humus content in the soil, allowing a permanent improvement in its fertility.
Currently, the compound can be produced other organic sources such as:
- Agricultural or food waste. The carbon / nitrogen (C / N) ratio can vary widely. Legumes are rich sources of N and herbs in C. The mixing of these two types of material is often appropriate.
- Residues of orchards, trees, landscaping companies, urban pruning and garden are organic primal materials.
