The aim of the study is to promote eco-design in vegetable oil sector by using LCA as a tool. In 2011, the vegetable oil sector participated to the French national experimentation on environmental labeling for two standard oils : sunflower oil and rapeseed oil. The complete life cycle of oils has been studied from the seed production to the end of life of the packaging. The data have been collected from different industrial sites that illustrate the diversity of French crushing, refining and packaging sites. The results of this study are a relevant overview of sunflower and rapeseed oils produced in France. Nowadays, companies from the oil sector use these values to compare them to their own process values and to evaluate the improvement due to their eco-design strategy.
Since 2011, some methodological aspects changed : (i) update of background data (new version of Ecoinvent database), (ii) new data available on agricultural stages (AGRIBALYSE® program), (iii) new recommended methods for environmental indicators, (iv) new pattern for end of life, etc. Effects on LCIA results could be huge, even if life cycle inventories for industrial transformation (yield, energy consumption, etc.) are still the same, that could lead to misunderstanding of LCIA results by stakeholders. In this context, ITERG (French institute of vegetable oils and fats) helped industrials to deal with these changes.
This work highlights the importance to fix, for a given industrial sector, methodological aspects for all the stakeholders of the sector. ITERG, FNCG (French federation of vegetable oil sector) and Terres Univia (Interprofessional organization for vegetable oils and proteins), with the help of Terres Inovia (technical center for oilseed crops, grain legumes and industrial hemp), wrote guidelines for assessing the environmental impacts of vegetable oils. The aim of these guidelines is to set sector-specific procedural rules to be used. These guidelines give recommendations on functional unit, allocation method, environmental indicators to be considered, and propose default values that are not readily accessible or that have little impact on the LCA results, and a list of data that can be excluded from scope of the study. Alongside this research work, ITERG has also developed an Excel tool for assessing the environmental impacts of the entire vegetable oil industry product range. This tool substantially reduces the timespan to calculate environmental impact of vegetable oils.
