LCA of innovative solutions of food loss and waste valorisation opportunities at Institut for Fødevarevidenskab - Københavns Universitet

Future food security is challenged by local and global constrains, such as increasing population and climate change. The current food supply chains, from production to final consumption and waste generation, is responsible for a 1.3 billion tonnes food being wasted before reaching the consumers worldwide, of which 88 million tonnes of such waste food production occurs inside EU.

These huge amounts of food being waste is associated with environmental impacts. As such, FW accounts for 25% of all water used by agriculture annually and 23% of all cropland. Overall, FW is responsible for 8% of global anthropogenic greenhouse gas (GHG) emissions each year.

Despite being recognized as a global problem, there is a critical lack of clear guidelines and frameworks to achieve goals such as Sustainable Development Goal (SDG) 12.3, which aims to halve food loss and waste per capita by 2030.

Not only is there an urgent need to stop food wasting, but also there is a need to avoid rebound effect by applying the strong sustainability principles to ensure food waste prevention prior to valorization. The latter calls for innovative (social and technology) solutions with the capability to tackle these environmental and social challenges.

The Master project is part of the HORIZON2020 project FoodRus- Circular solutions for resilient food systems ( Key research question to be answered are: 1) from a life cycle perspective, what are the environmental impacts different food loos and waste valorization opportunities? 2) What are state of the art innovative food loss and waste (FLW) prevention strategies exists that eliminates/minimizes the environmental footprint of FLW? 3) Which sustainability criteria should be monitored to avoid rebound effect from future FLW valorisation systems

To answer these questions, the following investigations will be performed: 1) Review the state of the art solution for FLW valorisation opportunitites, 2) Use life cycle assessment to analyze the performance of 2-3 selected FLW valorization technologies and 3) Critical assessment of the suggested technologies based on environmental, social and economic indicators.

For the assessment, primary data from project partners are to be collected. To fill potential data gaps, secondary data sources such as scientific literature and industrial reports are to be consulted
