Book Description
In the disposal phase of shopping bags/textile products, recyclability is one of the primary factors that need to be considered in evaluating the eco-impact. There are no models or approaches to quantify the recyclability potential of various textile fibres and raw materials used for shopping bags in terms of their environmental and economic gains. An attempt was made in this research to develop a model to quantify the recyclability potential index (RPI) of various textile fibres and raw materials used for shopping bags. Results of the RPI model indicate that polypropylene and polyester outscored all the other materials in question. Apart from reusability and recyclability, biodegradability is also an important focus in the ecological category. This research employed the results of a biodegradability test conducted for various shopping bags on the same platform using the soil burial test. Soil burial test results showed that paper bags followed by cotton bags demonstrated better biodegradation results. Regarding consumption behaviour, the perceptions or opinions of consumers have to be taken into consideration to make the end-of-life scenario values in the life cycle assessment calculations rather than using assumptions of the usage and disposal values. LCA studies reported to date on various shopping bags have used an assumption to model the end-of-life scenarios of various shopping bags, but this may not reflect reality. Hence a questionnaire survey was conducted in this research among different user groups in Mainland China, Hong Kong and India and the results from the real users were utilized to model the end-of-life phase of the various shopping bags. With the aid of the eco-functional model where the values from the discussed aspects are synthesized, eco-functional capacities of any product can be assessed and an "eco-functional" score can be assigned to any product. 23 samples made out of different types of shopping bags were assessed in terms of their eco-functional properties and the eco-functional score of each bag was evaluated and the results are presented. The results of the eco-functional assessment reveal the importance of every aspect of a product to meet the requirements of eco-functional assessment. For the eco-functional assessment combined with LCA study various shopping bags, a suitable functional unit based on consumption statistics from Mainland China, Hong Kong and India was earmarked for this LCA study. Detailed life cycle inventory details were collected for various life cycle phases of different types of shopping bags. Carbon footprint, ecological footprint and eco-damage assessments were made to quantify the life cycle impacts of each phase of the various shopping bags with the aid of SIMAPRO version 7.3 of LCA software. The LCA results revealed that each phase of life cycle impacted the final result and the reusable bags outscored single use bags in all three territories. Nonwoven bags made out of polypropylene followed by polyester and woven cotton bags caused fewer life cycle impacts. LDPE bags were shown to create higher impacts in the list of samples chosen for this study. Also the life cycle impacts of shopping bags used by an average Indian were found to be less compared to those for Chinese and Hong Kong residents. It was also apparent from the LCA results that the greater degree of reuse selected, the less the carbon footprint, ecological footprint and eco-damage in all the three territories. Even a small contribution from the consumer's side, to reuse a bag one more time, would make a great difference in terms of mitigating environmental impact. Consumer's support in terms of reusing a bag till its last point in life cycle and recycling it rather than disposing to landfill, supported by government recycling policies, will reduce the environmental impacts made by different types of shopping bags.

Book Description
Life cycle assessment (LCA) is used to evaluate the environmental impacts of textile products, from raw material extraction, through fibre processing, textile manufacture, distribution and use, to disposal or recycling. LCA is an important tool for the research and development process, product and process design, and labelling of textiles and clothing. Handbook of Life Cycle Assessment (LCA) of Textiles and Clothing systematically covers the LCA process with comprehensive examples and case studies. Part one of the book covers key indicators and processes in LCA, from carbon and ecological footprints to disposal, re-use and recycling. Part two then discusses a broad range of LCA applications in the textiles and clothing industry. - Covers the LCA process and its key indicators, including carbon and ecological footprints, disposal, re-use and recycling - Examines the key developments of LCA in the textile and clothing industries - Provides a wide range of case studies and examples of LCA applications in the textile and clothing industries

Book Description
This book highlights the notion of Circular Economy under the umbrella of Sustainability because of the widespread momentum it is gaining. Today the whole world is certainly in emergent need of an alternative system to traditional economy which is linear, i.e. make, use and dispose to get rid-off the waste and very important to ensure continuous use of resources, which is possible by the advent of circular economy. A circular economy aims to utilize the resources in use for as long as possible, extract the maximum value from them during use, then recover and regenerate products and materials at the end of each service life vis-à-vis traditional linear model. This book discusses circular economy in terms of assessment with various case studies.
