Funguschain

Problem statement

Converting value from mushroom waste into value added products contributing to the theme of circular economy by replacing use of fossil fuel-based plastics.

Executive summary

The FUNGUSCHAIN focused on extracting value from the agricultural offcuts of commercial mushroom farming. The approach focused on processing these offcuts into bio-based functional additives and biopolymers using a cascading approach to separate the valuable components into a spectrum of products. The project aimed to prove its industrial viability by building a new biorefinery and modifying industrial current manufacturing lines. The biomolecules and building blocks isolated from the mushroom wastes have been tested and validated for industrial production in three value chains for the European economy, notably food supplements for the elderly, plastic products and industrial film products such as bags and gloves.

Value chain description

The project aimed to demonstrate an integrated process of valorisation of agro residues from mushroom industrial cultivation into bio-based functional additives and biopolymers. A 4-step cascading approach is followed Pretreatment methods like a) Microwave assisted extraction, b) Pressurized hot water extraction, followed by c) Fermentation of the extracted media for biopolyester formation then d) Anaerobic digestion of remaining biomass producing compost, biofertilizer and biogas. These high value molecules from the fungal residue were used to produce a wide range of products like cosmetic, food and bioplastic

Market deployment considerations

Sufficient scale of mushroom residues are required. The global bioplastics market is projected to grow from $7,616.0 million in 2021 to $15,552.3 million in 2028 at a CAGR of 10.7% in forecast period 2021-2028.

Environmental considerations

For every kilogram of mushrooms produced, about three kilograms of soil-like material containing straw, manure and peat is left behind. FUNGUSCHAIN is transforming this residual streams into sustainable bio-based and biodegradable films for agriculture.

Social Considerations

Funguschain approach can support a more circular approach within the mushroom sector, ensuring farmers can generate additional source of income by utilizing the mushroom byproducts in a cascading biorefinery
