Setting up the new multipurpose refining and modification plant in Lauwersoog by telson and Rols Technology represents great opportunities for the Dutch shrimp industry. It is known that the shrimp caps contain substances that can produce a great deal of value. The technique of processing these shrimp caps is still very expensive at the moment, but the options for processing especially chitin and chitosan in a biorefinery factory are very large. Within the upcoming valorisation project, the focus is on developing a chemical and biochemical shrimp caps refining protocol, which should result in the final design of the multipurpose refining and modification plant with which chitosan formulations will be produced, which can meet different market and product quality requirements and respond to changes in market demand.The objectives of this project plan are summarised as follows:•Deepening and possibly broadening the application testing in work packages 1 to 4 with, modified or unmodified chitin and chitinase, as obtained by laboratory scale production;•Designing a pathway of refining by-products such as bio-acetate in particular applicable in the chemical and/or food industry; • Defining the product requirements, which must be met in order to be able to fulfil these applications in the market (preferably in consultation with potential customers); •Adapting the shrimp caps refining protocolas well as setting up an enzymatic refining route to meet the above-mentioned product quality requirements and further greening;•On the basis of this adapted protocol, create and re-test products and then take all results as a starting point for the design/design of a multipurpose refining pilot plant to set up in Lauwersoog in work package 5, with which both food-grade and industrial products can be made, which can meet different market and product quality requirements and respond to changes in market demand (expanding/risk reduction) and further greening.A successful implementation of Work Package 5 will demonstrate the technical and commercial potential of the refining and modification technology for chemical and enzymatic modification of chitin to various chitosan formulations and the possibilities for innovative applications with a lower carbon footprint. For telson and Rols Technology, the project will result in significant sales and growth of the organisation. Thanks to the results of this project, the shrimp caps biorefinery technology can be scaled up in Lauwersoog to larger volumes and industrial production of unique green raw materials that are applicable for distinctive applications in the chemical and/or food industry. Finally, this project will contribute to achieving a high growth in employment and turnover at the end of this project in the Groningen companies concerned. In particular, the local population will benefit from the results of this project through the expected growth in regional employment in Lauwersoog and its surroundings. The results of the project also lead to a major improvement in the Northern Netherlands employment and the Northern Netherlands Gross Regional Product (BRP). The innovation project leads to the valorisation of shrimp caps into sustainable raw materials for chemistry, which contributes to the greening of the chemistry clusters in Delfzijl and the (bio)polymer cluster Emmen, and links shrimp fisheries to chemistry.
