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 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.

Waste management and recycling is the fundamental part a sustainable economy. For more efficient and safe recycling, it is necessary to use intelligent systems instead of employing humans as workers in the dump-yards. This is one of the early works demonstrating the efficiency of latest intelligent approaches. In order to provide the most efficient approach, we experimented on well-known deep convolutional neural network architectures. For training without any pre-trained weights, Inception-Resnet, Inceptio...
Kinetic modeling of enzymatic hydrolysis of pretreated kitchen wastes for enhancing bioethanol production
Çekmecelioğlu, Deniz (Elsevier BV, 2013-03-01)
It is well known that use of low cost and abundant waste materials in microbial fermentations can reduce product costs. Kitchen wastes disposed of in large amounts from cafeterias, restaurants, dining halls, food processing plants, and household kitchens contain high amounts of carbohydrate components such as glucose, starch, and cellulose. Efficient utilization of these sugars is another opportunity to reduce ethanol costs. In this study, the effect of pretreatment methods (hot water, acid solutions, and a...
Solvent recovery from photolithography wastes using cellulose ultrafiltration membranes
Savaş, Aygen; Çulfaz Emecen, Pınar Zeynep (2022-04-05)
Solvent recycling and reuse are indispensable for ensuring a sustainable chemical industry and circular economy. In this study we report the fabrication of cellulose ultrafiltration membranes and their application in recovery of propylene glycol methyl ether acetate (PGMEA) used as developer solvent in SU-8 photolithography. Cellulose membranes were fabricated via alkaline hydrolysis of cellulose acetate membranes in aqueous NaOH. Membrane permeance and molecular weight cut-off (MWCO) were tuned via changin...
Optimisation of the treatment and disposal of solid wastes in Northern Cyprus
Barışsever, Coşku; Solyalı, Oğuz; Sustainable Environment and Energy Systems (2016-9)
Solid waste management has been a key issue of Northern Cyprus for many years as only half of the wastes are properly handled at a sanitary landfill whereas the rest are currently being burned or buried inappropriately at many open dumping areas all over Northern Cyprus which is a serious threat to the public health and the environment. In this study, we propose a mixed integer nonlinear programming model to determine which treatment facilities to build and their sizes, whether the current landfill sho...
Performance-based landfill design: development of a design component selection matrix using GIS and system simulation models
Tarhan, B; Ünlü, Kahraman (Springer Science and Business Media LLC, 2005-11-01)
Designing environmentally safe and economically feasible landfills can be a challenging task due to complex interactions that need to be taken into account between landfill size, waste and site characteristics. The main focus of this study is, by interfacing the geographic information systems (GIS) with system simulation models (SSM), to develop a methodology and a landfill design component selection matrix that can enable the determination of landfill design components providing the desired performance wit...
