FATORES QUE AFETAM O DESENVOLVIMENTO DA COMPOSTAGEM DE RESÍDUOS ORGÂNICOS

Composting is a process of controlled aerobic decomposition and stabilization of organic matter in conditions allowing the development of termophilic temperatures. Such temperatures lead to a stable, sanitized, rich in humus and environmental friendly final product. The efficiency of a composting process is directly related to the factors responsible for an adequate development and multiplication of the aerobic microorganisms acting in the transformation of organic matter. In order to develop an adequate composing process a proper combination of humidity, aeration, C/N ratio, pH, granulometry and pile high must be reached. This review aimed to identify and analyze the main factors directly or indirectly affecting microbiological activity during composting process.
