| Abstract |
The article presents the issues of managing mass and energy streams flowing throughout entities being part of algal FAME chain of custody, in the context of the circular economy idea. The article presents a brief literature review concerning the modeling of circular economy. Findings from the literature review indicate that the starting point is business models or models describing the behavior of entities occurring in the value chain of a given product. The literature indicates that an adequate model describing circular economy is still being searched for. Integration of such a model with an environmental-oriented model is quite a new issue and it poses a challenge. It requires a much wider view on business relations, not only from the point of view of profit but also the attained environmental and social values. Thus, including parameters measurable in values other then economic or non-mesurable parameters requires a new modeling approach. For this purpose, a definition of such values is needed. The article presents an algal FAME production model in accordance with the guidelines for creating a circular economy business model. The main players and system boundaries were identified, and the flows of mass streams and energy among installations were described for the model. The system boundaries covered not only entities occurring along the supply chain but also entrepreneurs supplying feedstock and receiving products. GHG emission (or other assessed environmental impacts) generated by these entities is included in the calculation made for the whole system. An inventory table was also drawn up. The article presents the algorithm of building such a model. The optimization of such a model is based on selecting stream flows between particular economic operators in such way to achieve an effect assumed for a whole system (e.g. minimization of GHG emission) but not for a single economic operator or product. |
