Circular bioeconomy for olive oil waste and by-product valorisation: Actors' strategies and conditions in the Mediterranean area.

The circular economy and bioeconomy can contribute to transitioning towards more sustainable production and consumption in the olive oil sector. This article is the first to analyse multi-actor strategies and multi-level socio-economic conditions for olive oil waste and by-product valorisation in the Mediterranean area using circular bioeconomy principles. Government policies, the strategies of corporations and farmers and consumers' perceptions are discussed, and various methods are applied, such as desk reviews, case studies and quantitative and qualitative surveys. The findings show strong aspirations for improved sustainability in the olive industry. Furthermore, waste and by-product valorisation strategies foster the creation of innovative practices. However, a common regulatory framework, public financial measures, new circular business models using innovative technologies, multi-actor collaboration and increased consumer awareness of the circular economy and new olive oil waste-based products are necessary for more efficient and sustainable use of olive resources. The policy and management recommendations presented in this study may aid in improving and innovating frameworks and practices for better sustainable management of valuable olive resources.
