New technologies were introduced in pig farming in recent decades, mainly targeting higher productivity and cost reduction. This production intensification requires large consumption of water to maintain farm hygiene and animal health. Throughout the cleaning activity, liquid and solid wastes mix with clean water generating a pollutant effluent containing high concentrations of organic matter and biota and water bodies. The production and incorrect disposal of these wastes in areas with low nutrient demand have been causing leaching and pollutant percolation, leading to high contamination levels of surface and groundwater resources. This economic activity has been responsible for causing major environmental problems. This study aims to review the literature and highlight ways that pig farm effluent can be reused, in order to savefresh water and chemical fertilizers, thus reducing pollution and environment degradation generated by this production sector.(AU)
