Composting and Organic Compound
Utilization of municipal waste for the production of humus
Composting is considered to be the most efficient process for the treatment and stabilization of organic waste, producing the acceptable cost of a product hygienic and useful.
In view of the increasing concern with the problems of pollution of the environment, associated with the scarcity of natural resources, the ideal for the fraction of organic solid waste would be the stabilization of these through biological processes controlled, thus allowing the recycling of nutrients and use of organic matter.
The solid waste and public, resulting this pruning, generate a considerable volume of plant material that can be used for composting and may contribute significantly to the reduction of damages caused by the disposal exercise of municipal waste, reducing the pressure on natural resources. This procedure allows for the production of compost for use in agricultural areas, production of seedlings and landscaping, since it recycles the nutrients present in these materials.
In the face of the lack of new areas for deployment of waste deposits and the need to extend the useful life of the same, the factor that now presents itself also as a strong argument for the implementation of systems of composting and recycling is the minimization of the amount of solid waste being disposed in these deposits.
Another environmental factor concerns the production of seedlings, tree planting in urban areas and the construction or renovation of raised beds for gardening in public areas.
The soil for such purposes, in large part, is imported the wild areas and rural areas surrounding the metropolitan, and is marketed under the name of ?land fertilized?, that is, it is made a mixture of this mineral soil with organic fertilizer.
The use of this residue may serve as a basis for that, at the same time gives a target of use of a material, which the point of view of the environment has sustainability and what is now dumped in landfills and garbage dumps contributing to the environmental problems, occurring concomitantly with a good economy to the public treasury.
Traditionally, they are composted source materials of agricultural. This type of material in general is free of contaminants and, when composted correctly, produces organic fertilizer of good quality and fit for use in agriculture. However, currently, the compound can be produced other organic sources such as:
- Waste agricultural industries or food. The ratio carbon/nitrogen (C/N) can vary greatly. Legumes are rich sources of N and grasses in C. The mixture of these two types of material is almost always appropriate.
- Waste of horticulture, arboriculture, landscaping companies, pruning and urban gardening are raw materials organic.
