The project is based on blue economy and green biotechnology. It aims at developing a method for sustainable growth and production of edible mushrooms and mushroom products (mainly food supplements) on foundations composed of cellulose waste and coffee grounding. Therefore, the method would be used as a means of recycling low-vaue waste into high-value products. Additional purpose of the project is to allow students to earn some income while working in their field and gaining experience, as well as encouraging the cooperation between Academia and economy.
