动物生产已经从自给模式转变为工业模式，降低了生产成本，但也增加了潜在的环境影响。如果污水处理不当，就会发生严重的污染事件。在巴西，液态粪肥通常储存在接收坑或有盖的泻湖（生物消化池）中，然后作为生物肥料在土地上施用。在一些地区，由于土壤支持能力低，粪便过量，在这些情况下，必须采用新技术来出口或处理过量的流出物。在巴西研究了粪肥在坑/覆盖泻湖中的储存时间和分离固体部分的新聚合物。处理技术，如猪粪处理系统（SMTS），已经从技术和经济的角度开发出来，以优化工艺，并为猪肉生产者提供一种技术替代方案，在增加产量的同时减少对环境的影响。(C) 2008 Elsevier Ltd版权所有。
Animal production has changed from subsistence to an industrial model, lowering production costs but giving rise to higher potential environmental impact. When the effluents are not correctly managed, serious pollution events can occur. In Brazil liquid manure is commonly stored in reception pits or covered lagoons (biodigestors), followed by land application as a biofertilizer. In some regions there is an excess of manure due to low soil support capacities, and in these cases new technologies have to be adopted to export or treat the excess effluent. Manure storage time in pits/covered lagoons and new polymers to separate the solid fraction have been studied in Brazil. Treatment technologies, like swine manure treatment systems (SMTS), have been developed from a technical and economical point of view to optimize the processes and give a technological alternative to pork producers increasing production while reducing environmental impact.
