Pork industry in Catalonia plays a foremost and representative role in the Spanish pork sector. Beyond the economic benefits, conventional practices in the pork industry also imply a number of environmental impacts that need to be dealt with. In this context, the environmental performance of traditional linear pork chain in Catalonia was evaluated through a LCA approach. The outcomes of the analysis showed that both fodder production and transport activities were identified as the critical stages of the system. Accordingly, alternative schemes based on circular economy principles were proposed and potential environmental credits were estimated. Within this framework, comparative results highlighted the advantages of moving towards a closing loop production system, where resource efficiency and waste valorisation were prioritised over final disposal options.
加泰罗尼亚的猪肉产业在西班牙猪肉行业中扮演着首要和代表性的角色。除了经济效益，猪肉产业的常规做法也意味着需要应对一些环境影响。在这种情况下，通过生命周期评估方法评估了加泰罗尼亚传统线性猪肉链的环境绩效。分析结果表明，饲料生产和运输活动都被确定为该系统的关键阶段。因此，提出了基于循环经济原则的替代方案，并估计了潜在的环境信用。在这个框架内，比较结果突出了朝着闭环生产系统发展的优势，在这种系统中，资源效率和废物增值优先于最终处置选择。
