The awareness of bioeconomy role within currently set EU policy targets towards zero carbon emissions and its contribution to achieving the sustainable development goals has been increasing during the last decade. However, it is not always straightforward how the development scenarios for bioeconomy can be evaluated on national level. Moreover, the large number of factors affecting the development of bioconomy is hard to evaluate altogether. Therefore, this study reviews currently available tools for bioresource value modelling in order to select an approach that is suitable for modelling different scenarios of bioeconomy development. As a result of the review, the study presents a methodology, which allows to estimate how higher added values of bioresource products can be achieved in different bioeconomy sectors. The concept of model is tested within a case study of fisheries sector in Latvia. The results of case study show economically viable scenario for added value target set for 2030. The concept of model is found to be adequate, and the use of the defined methodology is appropriate for bioresource value modelling.
