Résumé : | Taking into account that in the literature on pork-production Life Cycle Assessment (LCA) there are a few studies about the Iberian pig, the present article evaluates an extensive (growing-fattening) Iberian-pig system in Spain, producing meat for Iberian ham and other quality-labelled products. The study has been based on Cumulative Energy Demand (CED), Global Warming Potential (GWP), ReCiPe (midpoint; endpoint) and USEtox (human toxicity; ecotoxicity). The analysis involves feed (for pigs and piglets), transportation, drinking water, straw usage and building materials (concrete). The impacts have been evaluated per kg of live or carcass weight (two functional units). The results show that the total impacts (per kg of live or carcass weight) range from: 1) 22.05 to 28.19 MJprim (CED), 2) 4.37 to 6.19 kg CO2.eq (GWP 20a, 100a and 500a), 3) 0.86 to 1.08 Pts (ReCiPe endpoint single-score, involving Human health, Ecosystems and Resources), 4) 9.9 × 10−6 to 1.2 × 10−5 DALY (ReCiPe endpoint with characterisation), 5) 2.8 × 10−7 to 3.5 × 10−7 (species.yr) (ReCiPe endpoint with characterisation), 6) 10.12 to 12.66 CTUe (USEtox: ecotoxicity). Overall, the results show that the feed for the pigs is responsible for the major part of the environmental impacts. More analytically, maize and soya are the components with the highest environmental impacts due to factors such as transportation, use of fertilisers and diesel fuel. The discussion about pig-production environmental impacts and the role of extensive pig farming is enriched with comparisons with the literature on pig-production LCA. Critical parameters are identified and discussed, with the aim of proposing solutions to reduce pork-production environmental impacts. Finally, the usefulness of the present study and future prospects are presented. |
