Abstract: The production of olive oil in Mediterranean regions has a considerable negative impact on the environment due to the high production volume and short time frame. However, by applying the principles of the circular economy (CE), various waste management strategies can be identified for the olive oil supply chain. To assess the environmental impact of these waste management strategies, life cycle assessment (LCA) can be utilised. This study presents a systematic review of scientific LCA studies that examine the various wastes generated from the olive oil transformation process and different waste recovery scenarios in the agriculture, production, and packaging phases. We sourced 56 research papers from Web of Science, ScienceDirect, and Scopus, and surveyed them to identify the most commonly used valorisation scenarios and impact categories. Our results can inform decision-makers in selecting the most effective waste management strategies that can reduce environmental impacts by closing the waste loop.

Keywords: olive supply chain; olive oil waste; life cycle assessment; LCA; literature review; environmental impacts; valorisation scenarios.
