Life Cycle Assessment of Slaughtered Pork Production: A Case Study in Thailand
Pork is a staple food in many cultures worldwide and plays a significant role in global food systems. However, the production of pork is associated with various environmental issues throughout its life cycle. This study employed a life cycle assessment (LCA) to evaluate the environmental impact of slaughtered pork production in Thailand. The system boundaries encompassed pig breeding, pig farming, and slaughtering. The primary focus was on identifying significant contributors to environmental burdens throughout the pork production chain. Three scenarios for pig feed compositions were assessed. The results indicated that pork production generated a total impact of 5.07 kgCO2-eq on global warming, 1.16E-03 kgP-eq on freshwater eutrophication, 4.69 m2a-eq on land use, and 4.97 m3 on water consumption. Pig feed production, particularly maize cultivation, emerged as a hotspot within the life cycle, contributing the highest impact across all categories. According to scenario analysis, the substitution of rice by-products and sorghum in pig feed tended to reduce the magnitude of the impact. Opportunities were suggested to improve the environmental performance of pork production, especially through feed strategies such as substituting high-impact ingredients with more sustainable alternatives and utilizing waste from pig farming and slaughtering.
期刊介绍：
The Environment and Natural Resources Journal is a peer-reviewed journal, which provides insight scientific knowledge into the diverse dimensions of integrated environmental and natural resource management. The journal aims to provide a platform for exchange and distribution of the knowledge and cutting-edge research in the fields of environmental science and natural resource management to academicians, scientists and researchers. The journal accepts a varied array of manuscripts on all aspects of environmental science and natural resource management. The journal scope covers the integration of multidisciplinary sciences for prevention, control, treatment, environmental clean-up and restoration. The study of the existing or emerging problems of environment and natural resources in the region of Southeast Asia and the creation of novel knowledge and/or recommendations of mitigation measures for sustainable development policies are emphasized. The subject areas are diverse, but specific topics of interest include: -Biodiversity -Climate change -Detection and monitoring of polluted sources e.g., industry, mining -Disaster e.g., forest fire, flooding, earthquake, tsunami, or tidal wave -Ecological/Environmental modelling -Emerging contaminants/hazardous wastes investigation and remediation -Environmental dynamics e.g., coastal erosion, sea level rise -Environmental assessment tools, policy and management e.g., GIS, remote sensing, Environmental -Management System (EMS) -Environmental pollution and other novel solutions to pollution -Remediation technology of contaminated environments -Transboundary pollution -Waste and wastewater treatments and disposal technology
