Clean Technologies and Environmental Policy

Ö KOPROFIT® is a model that was developed in Graz in 1991. In the meantime, the approach attracted companies and regions worldwide. The program is still running in Graz: the regional network includes a beginners as well as a club program for the continuation and sustainable development of the region. The overall goal of Ö KOPROFIT® is to provide a platform for an active transfer of experiences and know-how between companies, authorities, and experts. The key elements of the approach are group workshops, individual consulting, and the Ö KOPROFIT® award. The basic workshops handle the subjects cleaner production, waste management, energy and material flow analyses, environmental controlling and marketing, effective teamwork, creativity, and legal compliance. With this approach, considerable resource savings could be realized. An analysis of implemented measures demonstrates, the longer the companies have been participating in Ö KOPROFIT® the percentage of measures under the category "new technologies" increases. Thus, the demand on certain expertise to solve specific technical problems grows. In this context also the need to collaborate with providers and developers of technologies, as well as with funding bodies for extensive development projects increases. Particularly in small and medium sized enterprises (SMEs), investments in technological frames often face a barrier, as well as lacking time resources for the implementation. These are challenges that require the continuous adaption of the approach regarding input and structure. New subjects, changes within sectors, and personal conditions make Ö KOPROFIT® a dynamic innovative sustainability network. © Springer-Verlag Berlin Heidelberg 2012. Source

Journal of Cleaner Production

Cleaner Production is an organized approach to minimize industrial waste and emissions by increasing the efficiency of the use of materials and energy. It is propagated especially by UNIDO and UNEP as an approach to identify preventive measures to cut on waste and emissions from industrial activities. Case studies conducted by the authors in the last 10 years demonstrate, that in a number of cases water consumption per production unit of industries from the surface treatment sector, from food processing and from the textile industry could be reduced by 30-90%, auxiliary materials consumption could be reduced by 30-50%, and energy consumption of processes could be reduced by 15-25%. All these measures were actually economically beneficial for the companies, most of these measures paid back in less than one year [1]. The standard approach to apply Cleaner Production originates from chemical engineering. It follows the steps of: Drawing a process flow sheet - collecting input/output data - doing mass and energy balances - identify sources for waste and emissions - set priorities - identify options. In the process of option generation one generally relies on expert knowledge or on checklists which are available in different manuals or in the best available technology reference (BREF) notes.11The BREF-notes are documents developed by the European Commission to support companies and the relevant authorities in the process of upgrading their technology to best practice standards, as required by the IPPC directive (Integrated Pollution Prevention and Control; Directive 2008/1/EC). They state best practise regarding pollution prevention for most industrial sectors. This approach is strong with teams with an (chemical) engineering background. The authors wanted to develop a generic approach for option identification especially for teams with little formal engineering background or teams which have to go beyond their professional experience by using elements of the so-called TRIZ method (Theory of inventive problem solving, or originally Russian: "{A figure is presented}" (Teoria reschenija isobretatjelskich sadatsch)). TRIZ offers very strong tools for developing process improvement options on a generic level without specific technological knowledge about the process which shall be improved. The authors have found from their research that especially the concept of the Ideal Final Result, and the Laws of Evolution form a conceptual framework which can aid effectively in the identification of improvement options in a systematic way. © 2009 Elsevier Ltd.
