RECICLAGEM AGRÍCOLA DE BIOSSÓLIDOS: ASPECTOS AMBIENTAIS E ACEITAÇÃO PÚBLICA

Abstract

Human populations, as part of the Earth's ecosystem, have behaviors that act in the opposite direction to maintain the environmental balance. The main factors that alter this balance are related to the consumption of resources and energy and waste. Domestic wastewater is primarily composed of water bath and washing, urine, feces, uneaten food, soaps and detergents and its treatment, besides being a public health issue, is a measure of environmental preservation. The sludge is generated in Sewage Treatment Plants in significant quantities and its disposal is a serious environmental problem. Regarding the management of this waste, you can opt for the controlled disposal or use. The beneficial changes in physical, chemical and biological soil properties, increased agricultural productivity and the resulting socio-economic benefits make the agricultural recycling practice amongst the most appropriate forms of final disposal of waste sludge. However, the lack of public acceptance of biosolids use, both by producers and final consumers, it may be a factor of viability of the activity. The present work aims to develop a reflection on the acceptance of food grown in soils treated with biosolids by society and possible proposals for future research on its agricultural recycling
