Original Abstract

The Circular Economy principle has to be applied more vigorously to tackle the rapid depletion of resources globally. The industrial and urban symbiosis are patterns implementing Circular Economy that is to maximise the recycling and reuse of resources within a collaborative environment. However, the circularity rate of the system cannot reach 100 %. This is not a sufficient criterion for designing and operating symbiosis in an optimal way. The current work shows that it is crucial to consider the cost, resource, exergy and footprint implications explicitly, in a combined way, for finding the optimal circularity rate. The proposed model is applied to evaluate the trends of the total cost, exergy footprint, water and Greenhouse gas footprints. The case study on the treatment of Municipal Solid Waste is used as a demonstration for evaluating the trade-offs between the cost, Exergy Footprint and environmental footprints against the circularity rate. The results show an approximate 10 % difference between the optimal circularity rates for Water Footprint minimisation and cost/exergy input minimisation. The discrepancies between the footprint and cost optima point to the need for an integrated eco-cost model to account for the monetary penalties from pollution. © 2021 University of Split, FESB.
