在服装生产过程中，产生了大量的废物。may take between one to five months to fully biodegrade, with the condition that the waste comprises only of organic cotton fabrics. The waste generated is a mixture of natural as well as synthetic fibre, with 20 to 200 years of decomposition time. Each chemical treatment elongates its biodegradation time. A viable solution to this problem may be the adoption of every technique resulting in lower waste generation. Zero waste Fashion may be a step towards achievement of sustainability. A Zero waste policy must be adopted to identify inefficiencies in the use of inputs like raw materials, power and workforce. Zero waste policy supports every phase of the sustainability movement. This paper is centered on the main causes of waste generation in garment industry and the Zero waste generation techniques of garment production and other means of waste reduction which can be adopted to make the fashion industry sustainable.
