Recently, however, the utilization and recycling of waste has become even more important due to the scarcity of unprocessed virgin materials and concerns over the non- sustainable use of natural resources. In addition to this, the increasing cost of waste management and limited landfill space have also increased interest in recovering waste as either material or energy. There is an increasing variety of products that have been produced by using recycled material as the main raw material. Training materials on Recycling of textile materials describe recycling of textile materials- mechanical recycling of textile and other thermoplastic materials with focus on PET bottle recycling; and chemical recycling with focus on carpet recycling. 1 MDT »Recycling« Recycling of textile materials 1 INTRODUCTION Mankind used some 72-75 million tons of fibre in 2007, of which EU with 10 million of tons is the largest consumer and second biggest producer in the World. The average fibre consumption is 11 kg/head, with the American consumer making the largest footprint with over 32 Kg/head. The Turkish or Mexican consumer stands at 10 kg/head, Indian and Chinese consumers at 3-5 Kg/head. Global fibre consumption has been increasing at a rate of 7-10% a year between 2002 and 2007, and even in developed countries it is still growing, owing mainly to fashion.
