In circular economy (Ce), the value of products and materials is maintained for as long as possible. What has previously been considered waste is now a resource that can be reused and reintroduced to the production cycle. Therefore, waste management of both technical and bio-based waste streams plays a central role in the transition towards Ce. In bioeconomy, the materials are to a certain extent circular by nature. however, biomaterials may also be used in a rather linear way. according to the european Commission, the transition towards Ce needs to be supported on local, regional and national levels. Thus, to enhance sustainability and get the full potential out of bioeconomy, the Ce principles should be applied to reach bio-based Ce. This paper presents the results of a qualitative assessment that was carried out in Finland, Spain, Slovakia, greece, romania and France. Selected national and regional strategies were identified, compared and analyzed from the perspective of Ce and bio-based Ce. at the time of the study, the added value of Ce was recognized in most of the national and regional level strategies studied, through objectives concerning e.g. waste management or bioenergy. Bio-based Ce was hardly ever included as a term but circularity aspects were referred to for example through biowaste management. Waste management appears to be the main driver in the transition towards Ce. This is evident also in the case presented from Slovakia. yet, in order for Ce to become an integral part of national and regional policies, a more comprehensive understanding of the Ce mechanisms should be achieved. Supported actions on both small and large-scale are needed. The research is partly an outcome of the ongoing Interreg europe project BIOregIO, where the bio-based circular economy is boosted through a transfer of expertise about best practices, aiming at changing regional policies to support bio-based Ce.

Forecasting of hospital solid waste generation is a critical challenge for future planning. The composition and generation rate of hospital solid waste in hospital units was the field where the proposed methodology of the present article was applied in order to validate the results and secure the outcomes of the management plan in national hospitals. A set of three multiple-variable regression models has been derived for estimating the daily total hospital waste, general hospital waste, and total hazardous waste as a function of number of inpatients, number of total patients, and number of beds. The application of several key indicators and validation procedures indicates the high significance and reliability of the developed models in predicting the hospital solid waste of any hospital. Methodology data were drawn from existent scientific literature. Also, useful raw data were retrieved from international organisations and the investigated hospitals’ personnel. The primal generation outcomes are compared with other local hospitals and also with hospitals from other countries. The main outcome, which is the developed model results, are presented and analysed thoroughly. The goal is this model to act as leverage in the discussions among governmental authorities on the implementation of a national plan for safe hospital waste management in Palestine.
