Eskişehirdeki tüketici sonrası tekstil atıklarına geri dönüşüm ve ulaşım etkilerinin yda ile incelenmesi

Textile is a material that could be diversified the most, therefore considerations of textile waste recycling/ reuse and the effects of its landfill should be carefully considered. In this thesis, transportation and recycling effects on the household textile waste of Eskişehir was investigated by using Life Cycle Assessment (LCA). Disregarding consumer using stage, the entire life cycle of waste produced from cotton was evaluated. LCA inventory was included for occupation of land, water consumption, chemical consumption, energy consumption, emission to air and water and transportation network. LCA analysis was performed using SimaPro 9.1.0.8 faculty to assess global warming potential (GWP) and single score result. According to the results, the GWP of 4190 tons/year pure cotton household textile waste in Eskişehir was estimated to be 57340 tonnes/year CO2eq from the beginning of the cotton production until the landfilling. The distance of transportation of the initial material of cotton did not have a significant effect on single score or GWP of the cotton household waste. However, changing the transportation length of the household cotton waste had an impact of the results. The minimum environmental vi effects were observed with 301.68 tonnes/year CO2eq reduction when all the household textile waste is recycled in a relocated recycling facility next to the landfill. Sensitivity analysis showed that the GWP caused from reinstating the sorting facility of the city next to the landfill is equivalent to 92.7 kgkm truck transportation load. This effect could be reduced via increasing the recycling rate by approximately 2%. The study indicated that if all the pure cotton textile waste could be recycled, 40% CO2eq emission reduction could be achieved compared to the current situation in Eskişehir. The overall results of this study clearly demonstrated that increasing the rate of recycling was the most effective changes for Eskişehir.
