Avaliação da eficiência da compostagem mesofílica e termofílica.

Abstract

The composting of the solid waste organic fraction, produced in several humans activity, compose a way of valorization of the crescent importance in the integrate management politics of solid waste with economics and environmental benefits. Specially by the fact of the chance to produce a stabilized and safe product, rich in humus, that when mixed with the soil enrich your quality, making possible better growth of the culture and combat erosion in degrade soils. In this perspective presents a study evaluating the effect of mesophilic and termophilic temperatures in the LESA composting process, that was developed in the period of march to June of 2001. Was also evaluated a experiment maintained under mesophilic temperature in a no pavement patio. To the accomplishment of this study was mounted composting piles with the same material for the tree experiments, solid waste organic fraction deriving from Coimbra - MG. The results showed that the experiments maintained under termophilics temperatures presents compatible results for the formation of acceptable compost, but the two others experiments maintained under mesophilic temperatures did not have a lot of acceptable conducts, presenting operating problems, requesting bigger areas and making impossible to obtain a god organic compost.
