Title: Life Cycle Assessment of Large-scale Piggery for Environmental Assessment
Abstract: Life cycle assessment (LCA) methodology was used to establish inventory of energy consumption and pollutant emission and to assess life-cycle environmental impacts of large-scale piggery,and then the way could be found for lessen negative environmental impacts.Four impact categories were investigated,including energy depletion,eutrophication,global warming and acidification,with the impact indices of 8.38×10-3,1.91×10-3,9.80×10-3 and 2.01×10-2,respectively.The life cycle was divided into three stages,i.e.feed ingredients manufacture,swine rearing and wastes disposal,with the environmental impact complex index of 2.52×10-2,1.23×10-2 and 2.71×10-3,respectively.The results showed that manufacture of feed ingredients had the largest environmental impact.Therefore,reducing nitrogenous fertilizer consumption and implementing energy-saving and cleaner production in the production of fertilizers were essential to control the life cycle environmental impacts of large-scale piggery.
