PP, LDPE, HDPE and acrylic are also belong to non-biodegradable category [14]. Fibre recyclability and biodegradability refer to end-of-life option at the grave stage of products and largely contribute to solid waste management and enable us to dispose/ recycle them in a safe manner. Hence a special consideration is given here in this model for these two factors. Scoring scheme developed and the corresponding value of raw materials under discussion is given in Fig. 1. 2 Details of Stage 2 Next stage deals with the quantification of LCIA (life cycle impact assessment).

HTP ecom, i is the Human Toxicity Potential (the characterisation factor) for substance i emitted to the emission compartment ecom (= air, fresh water, sea water, agricultural soil or industrial soil), while m ecom, i is the emission of substance i to medium ecom. The equations for the calculation of Acidification, Eutrophication, Radiation and POCP are as follows [41]: Acidification Acidification ¼ X APi à mi ð3:8Þ i The indicator result is expressed in kg SO2 equivalents. AP i is the Acidification Potential for substance i emitted to the air, while m i is the emission of substance i to the air.

From the analysis it was understood that sewing technology seems to be better in terms of better environmental performance than its counterpart. Recommendations on feasible grounds to reduce the life cycle impacts were also discussed. This chapter also discussed the manual calculation of life cycle impacts pertaining to Chinese consumers of shopping bags. Different impacts were characterized, normalized and weighed pertaining to the impact values applicable to people living in China and the results were also compared with software results.
