Eco-efficiency and industrial symbiosis – a counterfactual analysis of a mining community

Complex utilization, a production model analogous to those described by industrial symbiosis, was planned at the Russian Kola Science Center in mid-1980. The model integrates the waste streams of mining industries in the Kola Peninsula in such a way that waste from one industrial operator becomes raw material for another. Using a counterfactual method, this article determines the eco-efficiency of the model between the years 1985 and 2005. A parallel study of the eco-efficiency of the actual system, i.e. in the absence of complex utilization, is then performed for the same time period. The study shows that complex utilization would indeed have yielded increased eco-efficiency, even though not all environmentally harmful emissions would have decreased. As a result of market collapse and the use of upstream pollution prevention together with traditional end-of-pipe technologies, however, the actual system shows net emission reductions similar to those modeled in complex utilization. It is suggested that in systems like the mining industry of the Kola Peninsula, with high production volumes and poorly developed environmental technologies, upstream pollution prevention together with traditional end-of-pipe technologies may prove more attractive than industrial symbiosis, despite the substantial increases in eco-efficiency of the latter.
