Perhaps you have never stopped to think, but what is considered a leach for you may not be that leach as well. In truth, the leach can have different purposes and destinations, and so be very useful. Right?! It may seem complicated, but it is simple.
Let’s go! In addition to the recycling process, already well known by us, the process of composition is becoming more and more widespread – in large and small scale -, to take advantage of the organic waste (that “kitchen waste”) that we produce.
Composting is the name given to the biological process of decomposition and recycling of organic material from remains of animal or vegetable origin through various microorganisms, with the purpose of producing an organic compost that can be applied not only to improve its characteristics, without offering risks to the environment.the use of composting plants in Brazil is a very recent process.
The first plants were installed in the 70’s and unfortunately, still many are the problems encountered in the process and in the quality of the composts. The first step to understand this process carried out in the plants is to keep in mind what are the “organic residues” that can be used as raw material in the compost.
When dealing with waste, the more varied the substratum, the better, since a greater variety of materials will provide a greater variety of microorganisms decomposing and acting alone. Household organic leach (hulls and excess of fruits and vegetables, coffee husks.
The first stage, after the arrival in the plants, is the separation of the wastes in categories – organic, metals, glass, papers, . After being separated, the material is heated and turned at high temperatures to be free of pathogens. After a period of about 120 days, the compost is ready and can be penetrated for use.
The fine products of the compost can be used mainly as garden tubs and vegetables. As it is an organic tube, it returns to the soil the nutrients it needs, increases its capacity to water and allows erosion control, avoiding the use of industrial fertilizers. Near the organic residues that we, Brazilians, produce, we have an unsuitable destination and can bring prejudices to just air and water.
The composting process, which is low-cost and relatively simple, can ease the situation of the leaches (which are still used) and diminish the load sent to the sanitary landfills. In Brazil, composed of organic material that is composting important to emphasize that to have a final product of quality, the residues must be separated according to their categories. Unfortunately in Brazil, the separation of the leach and the selective collection is still not widely spread and carried out due to the lack of knowledge of the population and the economic and logistic difficulties. And so… Are you doing your part in separating your leach?
