The waste minimisation in the chemical industry has shifted from the end-of-pipe treatment to the elimination of wastes at the source as well as environmentally sound internal recycling. Several systematic strategies based on the hierarchical process design have been developed and used in the practice. In the case of a chemical company that consists of several processes or plants it is necessary to co-ordinate the waste minimisation incentives on the company level. The main goal is to utilise the waste of a plant in another plant that is to design closed-cycle processing. This article describes a systematic two level procedure for the reduction of the global emission of a chemical company.
