The subject of the project is to carry out R & D work to develop a globally innovative product – biodegradable anti-caking agent, intended for use in fertilisers. A key innovative feature of the new product will be its biodegradability, achieved by replacing commonly used petroleum products, plant products. In order to meet the needs of customers, a recipe will be developed with physico-chemical parameters and functional properties (anti-caking and antypylating), meeting all the quality requirements of customers, which will be large companies producing artificial fertilisers (in Poland mainly entities from Grupa Azoty and ANWIL). The project concept was created as a result of business talks with future customers and will enable them to meet their needs in terms of preferences in the use of biodegradable additives for mineral fertilisers. The project, including industrial research and development works, has been divided into 5 stages and will result in obtaining a product ready for commercial implementation, verified qualitatively and usable by the Applicant and selected key customers. The project envisages five milestones, achieved in the next five stages: 1. Development of a verified base of raw materials necessary to develop ready-made recipes. 2. Determination of optimal parameters of the process of hydrotreatment of raw materials. 3. Positive laboratory biodegradability tests, physicochemical parameters and anti-caking properties of the formulations developed. 4. Preparation of a set of test batches of finished product for industrial tests, together with the development of an optimal blending technique. 5. Positive verification of the performance of the batch test performance of the product. The new product will be compressed
