摘要：Composting is the process of decomposition and transformation of solid organic substances by microorganisms (mainly bacteria and fungi) into a stable material, which can be used (depending on characteristics) in agriculture, instead of chemical fertilizers or land improvement works (soil improvement. The composting process consists of two stages: mechanical treatment and decomposition (fermentation). In the case of mechanical treatment, the waste is crushed, homogenized and prepared for biological treatment, fermentation. The fermentation stage consists in three main stages, namely the mesophilic fermentation stage, the thermophilic fermentation stage and the maturation stage of the compost.
