Özet:The main aim of this study was (i) to investigate the applicability of various sustainable production measures in different industrial sectors and (ii) to conduct a sectoral assessment study for a selected sector in order to contribute to the diffusion of sustainable production approach into Turkish manufacturing industry. As a result of the environmental performance evaluations, objectives were set for six companies from six different sectors in order to decrease the negative environmental impacts and production costs associated with the high impact processes/practices. To achieve these objectives, 77 options were developed and 19 options were selected/implemented in the companies. In the companies, significant water saving (849,668 m3/year) was achieved. In addition to water, 3,607 MWh of total energy was saved. Due to energy saving, CO2 emissions of companies were reduced considerably by 904.1 tons/year. Chemical saving (e.g. NaCl, CdO, NaCN) of 278.4 tons/year was achieved by process and technology changes. By this way pollutant load in generated wastewaters were decreased substantially. Within the scope of the sectoral assessment of Turkish textile industry, a three scale analysis (micro, meso and macro) was conducted by means of survey studies taking into account (i) the textile producer firms’ capacities and awareness, (ii) standards and demands of retailer companies as well as (iii) the existing institutional framework, strategies, supports and incentives. Survey study covered 76 textile producer firms, 10 retailer companies (e.g. multinational corporations) and 17 institutions. As a result of the analysis, recommendations were developed for the diffusion of sustainable production into Turkish textile industry. The results of the study show that the wide-spread uptake of proposed sustainable production measures would generate a tremendous change in the Turkish manufacturing industry even without heavy investments for technology changes. It is expected that the methodologies developed/followed throughout this study will shed light on future sustainable production applications and policies for the widespread adoption of this approach within Turkish manufacturing industry.
