Transition from Conventional to Sustainable Production: A Case Study in OSTIM Organized Industrial Zone

Organized Industrial Zones (OIZ) are places for manufacturing of goods and provision of services, established and operated in accordance with the provisions of the Ministry of Science Industry and Technology of Turkey. The process input-outputs and their environmental impacts are ignored in conventional OIZ’s. However, global conditions of competition have changed today and manufacturers need to consider the economic, ecologic and energy factors, reuse of products and raw materials, recovery of waste and the efficient use of all resources. They have to focus on cleaner production (CP) for being competitive in market. As a case study, 10 Small and Medium Sized Enterprises (SME) which are producing in different areas like rubber, metal working, galvanized coating, and casting were chosen. In each company, flow charts were analyzed, inputs and outputs were identified. Raw materials, chemicals, water and energy were taken as inputs. Since there was no continuous production in each company, all parameters were considered annually. All data was benchmarked with Eco-Invent database to make suggestions for clean production to each company. After cleaner production analysis, it was tried to reveal possible symbiotic relations between companies. After all analysis, data showed that energy efficiency based industrial symbiosis (IS) is more possible and efficient than waste-raw material exchange. Based on this, by creating a virtual eco industrial park, possible scenarios for the realization of industrial symbiosis were prepared. Examining the best practices of eco-industrial parks in the world, an eco-industrial virtual park was designed for OSTIM OIZ for sustainable environmental friendly production.
