Development of multipurpose extraction unit for the processing of waste from wine industry into products with substantial added value
Viniculture generates a quantity of waste but appropriate methods for its processing have not yet been developed. Hence, it is mostly used for composting or combustion, although it contains considerable amount of bioactive substances, which can find use in agriculture, cosmetics, or food. The aim of the project in the first year is to select and optimize extraction methods for the processing of grape cane and wine marc, and design and assemble a functional sample of a multipurpose laboratory unit combining various extraction techniques (Soxhlet and ultrasonic extraction, maceration, temperature and pressure control), offering thus potential for the treatment of different plant waste. In the second year, scale up to a pilot plant will be performed to verify the designed technology.
