QUALITY PARAMETERS APPLICABLE TO THE COMPOSTABLE ORGANIC WASTE COMPOSTING PROCESS FROM MSW

Abstract

The establishment of limit parameters to guarantee the process control and the quality of the stabilized compost, resulting from the composting of compostable organic waste, is necessary in order to protect the environmental compartments. The final product of composting must be introduced into nature in a natural way and can be used for agriculture, plantations, soil stabilization and / or recovery of degraded areas. For this reason, physical, chemical, microbiological, macro-nutrient, micronutrient and heavy metal parameters must be assessed, throughout the composting process, in order to guarantee the quality of the mineralized compound so that it can be introduced into the environment in an efficiently and safely way. The correct segregation at the source and the proper management of Municipal Solid Waste (MSW), in composting plants, directly influence the quality of the compost formed and constitute one of the main challenges in the management of this waste. This work aimed, through a bibliographic review, to present and discuss the quality parameters that influence the process of obtaining a compound rich in nutrients and suitable for use in the soil, known as humus.
