Ingreen

Problem statement

INGREEN is an EU funded project that will develop functional innovative ingredients from dairy, paper and agro-food side streams through biotechnological processes for food, feed, pharmaceuticals, nutraceuticals, cosmetics and biodegradable packaging. With the help of safe microorganisms and newly developed eco-friendly technologies, new ingredients and products were made for the food, feed, pharma, cosmetic, nutraceutical, packaging sectors

Executive summary

The BBI JU INGREEN project has developed tailor-made biotechnologies for innovative products from safe microorganisms or eco-friendly sources found in dairy, agro-food and paper mill side streams and their by-products. It will help these sidestreams to become more sustainable and profitable by producing lactobionic acid (LBA), galactooligosaccharides (GOS), microbial safe biomasses from whey; polyhydrohyalkanoate-enriched biomasses and purified polyhydroxyalkanoates (PHA) from paper mill wastewater; and functional pre-fermented ingredients from rye/wheat milling fractions. Safe and characterised INGREEN ingredients will be used for developing innovative functional cheeses, bakery products and nutritious feeds, while GOS, LBA and pre-fermented bran will be used to produce prebiotic immune-stimulating gels, nutraceutical supplements and cleansers for human health

Value chain description

The Ingreen project can be segregated into 3 main clusters according to source of waste. The INGREEN researchers produced the following products using whey and enzymes. a) Innovative Caciotta cheese with accelerated ripening time compared to traditional caciotta cheese, b) Intimate cleanser enriched with LBA and GOS c) Vaginal gel. From wheat and rye bran it aims to produce a) Functional bakery products, b) Nutraceutical supplements. From paper milling wastewater it aims to produce a) Enriched PHA as animal feed, b) Purified PHA as biodegradable packaging film. Once optimized at lab scale, these sustainable biotechnologies were demonstrated in real operational environments at pilot scale

Market deployment considerations

The global cheese market size was accounted at USD 159.81 billion in 2022 and it is projected to surpass around USD 213.72 billion by 2032 with a registered CAGR of 3% over the forecast years 2023 to 2032. Bakery Products Market size was valued at USD 234.5 billion in 2022 and is estimated to witness over 4.4% CAGR from 2023 to 2032. The PHA market size is projected to increase from USD 93 million in 2023 to USD 195 million by 2028, at a CAGR of 15.9%

Environmental considerations

Eco-friendly approaches to produce safe and/or health promoting microbial biomasses and biochemicals, bio-packaging reducing environmental footprint

Social Considerations

The INGREEN project also showed a significant impact on building employee’s career. This is demonstrated by the large number of young researchers who have worked on the project, developed new skills and expertise, and who could potentially, thanks to the industrialization of the processes developed, by the INGREEN partners in the future
