Abstract

The objective of this paper was to assess the environmental performance of the production of pork products in Serbia. Life cycle assessment calculations have been performed to identify and quantify the environmental impacts from a cradle-to-grave perspective covering four subsystems: ‘pig housing farm’, ‘slaughterhouse’, ‘meat processing plant’ and ‘waste and waste water treatment’. Structured survey has been conducted in order to collect life cycle inventory input data. Six environmental impact potentials were calculated in this study: global
warming potential, acidification potential, eutrophication potential, ozone layer depletion, photochemical smog and human toxicity. The global warming potential associated with the production of 1 kg of pork products is 9.04 kg CO2eq. Acidification potential within the pork meat chain is 9.874 x 10-3 kg SO2eq while the eutrophication potential is 0.0151 kg PO4eq. The largest contributor to the environmental profile of meat production within the pork meat chain is the production of feed and manure management. Contributions of the processing plants are mainly due to water and energy requirement and use of refrigerants in the cold chain.
