The Gdynia Cotton Association in the agreement with the Institute of Natural Fibres and Medicinal Plants applied to the National Centre for Research and Development (NCBR) for the prolongation of the duration of the Project. The decision resulted from the fact that due to pandemic COVID-19, researches could not be conducted on time. German Partners i.e. Association for Research and Development in Materials from Renewable Resources (WNR) as well as Fraunhofer Institute for Microstructure of Materials and Systems (IMWS) also submitted the analogical motion to the German Financing Agency. Both Polish and German Agencies accepted the prolongation of the duration of the Project by 31 December 2020.
