Modern circular bioeconomy concepts undoubtedly involve the generation of value-added products by using modern, specific and efficient technologies. Enzymes as powerful biocatalysts are already used in many biorefineries. In the pulp and paper industry, environmentally friendly enzyme based processes such as for deinking, bleaching or refining have been developed more than 20 years ago, while implementation is still restricted due to the high enzymes cost. On the other hand, valuable components like residual cellulose fibres in waste streams, such as from deinking of recycled paper are currently under-exploited. Similarly, due to various reasons nitrogen rich waste streams from abattoirs are primarily used for energy production. Building on these facts, the major aim of this InduZyme project is the in-house production of enzymes used in the P & P and waste processing industries using cellulose present in deinking sludge as carbon source and abattoir waste as a nitrogen source and source of other essential nutrients for microbial growth.
The use of such waste streams, consequently not only leads to value added products namely enzymes (InduZymes) that are required by these industrial partners at lower cost but also reduces the amount of waste generated in the respective industrial processes . Hence, the InduZyme concept, after subsequent optimization and industrial scale-up will allow the companies to save cost both due to on-site enzyme production and due to converting waste difficult to dispose into valuable products. In detail, the tasks of InduZyme will involve enzymatic hydrolysis of cellulose fiber in deinking sludge in order to produce valuable sugars as carbon source for microbial enzyme production. Thereby, the nitrogen as well as other essential nutrients needed for microbial growth will be recovered from protein rich abattoir waste streams. Enzyme production will be accessed for e.g. cellulases, hemicellulases, lipases, proteases needed by the same industries for e.g. deinking and production of biodiesel, amongst for other enzyme based processes. This concept is novel and economically attractive since in contrast to many other concepts a market and demand for the value-added biorefinery products (i.e. the enzymes) already exists within the companies.
