Industrial symbiosis


„Industry and industrial processes act as converter of natural resources into products and services. Industry has an impact on environmental pollution throughout the whole life cycle of a product”. In order to ensure industrial sustainability one concept of industrial ecology is industrial symbiosis [1]. Industrial symbiosis shall demonstrate the analogy to ecological systems, where symbiosis and exchange are advantages. A well-known example is the industrial symbiosis in Kalundborg (Denmark). The unification of different enterprises and public bodies made a further utilisation of by-products possible by closing material cycles. This further caused also economic benefits for the participating companies [2].
So, by incorporating such a concept, lodgment or incineration of waste can be avoided as well as primary raw materials or rather energy sources can be preserved [3]. In order to realise industrial symbiosis, prerequisites are the technical possibility of exchange of production results and input materials as well as a cooperative relationship [1].
