Nutritech - Rethinking the Food Chain

NEW REPORT: Utilisation of co-streams in the Norwegian food processing industry – A multiple case study

25.8.2014 9:26


The CYCLE project has published a report about co-streams in the Norwegian food industry based on a multiple case study of vegetable, fish and poultry processing plants. The report describes material flows in the plants as well as chemical compositions of selected co-streams. Furthermore, the authors discussed possibilities to produce feed, energy and fertilisers from co-streams. The main author is Steffen Adler from Bioforsk - Norwegian Institute for Agricultural and Environmental Research, and a group of writers from VTT Technical Research Centre of Finland, SINTEF Fisheries and Aquaculture and Felleskjøpet Fôrutvikling AS contributed too. 

Co-streams formed in the food-processing industry contribute to food loss in the food chain, but they may also be a source for alternative utilisation. During visits of plants representing the Norwegian vegetable and potato, white and pelagic fish, and poultry processing industries in June 2013, CYCLE-scientists studied the flow of raw materials and co-streams with the aim to explore the potential for better utilisation. A further mapping, presented in a recent Bioforsk report, showed that on average 75% of the raw materials were utilised in food products and 21% in feed products. Only 3% were disposed of in landfill. Possible improvements in the utilisation of raw materials and co-streams include a higher degree of utilisation in food products, and developing new or improved feed components from co-streams with increased nutritional value. Feed potatoes and vegetables, and feathers, bones, blood, viscera and skin from fish or poultry have considerable potential for better utilisation for food or feed.

"Total utilisation of raw materials in the supply chain for food with a bio-economical perspective", CYCLE, is a 4-year-project (2013-2016) and it is coordinated by Dr. Marit Aursand from SINTEF Fisheries and Aquaculture (Norway). Other project partners are VTT (Finland), Bioforsk (Norway), NOFIMA (Norway), University of Copenhagen (Denmark) and SIFO (Norway). Companies from food, feed, packaging, machinery, fertilizer and bioenergy sectors in Norway are involved in the project. The main financier of the CYCLE project is the Research Council of Norway.
