The aim of this research is to present the use of e-commerce instruments in sell-buy transactions of chosen coffee waste products. The theoretical part of the study consists of comparative and synthetic analyses. The revised public source of information coming from well- -known organizations are used. The practical part of the study consists of in-depth expert structured interviews (N = 8). The results of the study are multi-faceted. The practical business examples shown in the article demonstrates the possibility of introducing a bio-circular economy on a large scale in Europe and Asia. The results can be used by state institutions for the implementation of a bio-circular economy policy in various types of production activities, e.g. biomass, bioenergy, feed, supplements, drugs to fight obesity and diabetes, cosmetics.
