Circular bioeconomy in action: Collection and recycling of domestic used cooking oil through a social, reverse logistics system

Abstract

The inappropriate disposal of millions of tons of domestically produced used cooking oil (UCO), either down domestic household drains or in landfill, causes significant detrimental effects on the environment but also constitutes the loss of a valuable resource, since used cooking oil is a sought-after feedstock for biodiesel production. This paper presents findings from a social reverse logistics system, called InnovOleum, for collecting and recycling domestic used cooking oil through schools. The disruptive, social aspect of InnovOleum derives from the provision of funds from the sale of the collected used cooking oil to be invested within the participating schools in ongoing environmental education and green infrastructure and technology. To date, over 200,000 Euros have been distributed to schools for this purpose. No other schemes with similar potential to fully harness the environmental and social benefits from the collection and conversion of domestically produced used cooking oil have been found in literature. This publication can therefore significantly contribute to the knowledge base and facilitate the transfer of this scheme elsewhere.
