Waste Management Technology for Sustainable Agriculture

Abstract

The process of collection, transport, disposal, recycling, and monitoring of wastes is called waste management. The waste management is undertaken to recycle the wastes so as to reduce the ill effects of wastes on environment, health, and aesthetics. There are several kinds of wastes produced such as agricultural wastes, municipal wastes, industrial waste, mining waste. Some wastes are more hazardous such as medical wastes and nuclear wastes. Various techniques are used for the management of wastes which includes landfilling, incineration, anaerobic digestion, pyrolysis, plasma gasification, recycling, composting. Anaerobic digestion produces biofuel in the form of biogas. Plasma gasification results in the generation of electricity from wastes. Recycling of wastes involves the collection, sorting, and reprocessing of wastes into new products. Vermicomposting is the preferred form of composting as it results in the formation of vermicompost called black gold due to the presence of rich nutrients and growth promoting factors in it.

Thermodynamic Analysis of Plasma Gasification of Agricultural Waste

“…It is feasible to accelerate the process of producing fuel gas, which is mostly composed of synthesis gas (CO + H 2 ), and to signi cantly boost the productivity of the plant (by 150-200 times compared to biogas plants) by the plasma-chemical processing of waste from the agro-industrial complex [15][16][17][18][19]. This is made possible by the plasma gasi er's high temperature and a substantial decrease in the amount of time needed to treat the waste.…”
