Impactos Ambientais Dos Resíduos Da Suinocultura Industrial E Alternativas De Tratamento

Abstract

Modern swine has been notable for growth in the last decades, however, the intensification of pig farming has been causing great environmental problems, evidencing the pollution of natural resources such as air, soil and water. In regions with high concentration of farms, most animal waste is released to the soil and water courses without criteria or prior treatment, becoming an important source of environmental pollution. When waste is properly managed, it is no longer polluting and becomes a valuable source of fertilizer, as well as preserving and improving the physical, chemical and biological properties of the soil, avoiding the use of petroleum-based inputs that are highly energetic and expensive. In our country several methods are used for the handling and treatment of waste, each of which has its own particularities. This paper deals with the environmental impacts caused by the irrational disposal of industrial swine residues and presents the legal techniques of treatment of swine manure, aiming at its reuse with higher agronomic value.
