Life Cycle Assessment (LCA) of protected crops: an Italian case study

Abstract In this paper a Life Cycle Assessment (LCA) of protected crops was carried out. In particular, energy and environmental performances of peppers, melons, tomatoes, cherry tomatoes, and zucchini in different typologies of greenhouses (tunnel and pavilion) were assessed. The study aimed at assessing the ecoprofile of each product and the share of each life-cycle step on the total environmental impacts. The related process flow chart, the relevant mass and energy flows and the key environmental issues were identified for each product. Collection of primary data was conducted by means of a detailed questionnaire distributed to a producer company in southern Italy. The analysis was developed according to the LCA standards of the ISO 14040 series. The results showed that for all the examined vegetables the packaging step and the greenhouse structures have a relevant share in the environmental impact distribution. Further tunnel and pavilion greenhouses are characterized by comparable ecoprofiles and both of them are characterized by lower energy consumptions than greenhouses in the North of Europe, due to the non-use of auxiliary heating systems in the former.
