where are all your old clothes? was it discarded at random or sent to the recycling bin? according to the china textile industry federation, if china's waste textiles can be fully recycled, it is equivalent to saving 24 million tons of crude oil a year, saving nearly a third of the cotton planting area and reducing carbon dioxide emissions by 80 million tons.
chinese academy of engineering consulting research project "waste resource recycling technology development strategy research, chemical fiber textiles" work conference held in beijing recently, combing comparison study in depth the resource recycling waste chemical fiber textiles at home and abroad on the basis of present situation and development trend, put forward the our country the key task of resource recycling waste chemical fiber textiles, made clear the development direction of whole industry chain technology system.
china is a major country in the production and application of chemical fiber in the world. in 2016, the total production of chemical fiber reached 49.44 million tons, accounting for 69.4% of the total global chemical fiber, and the total processing of textile fiber reached 54.2 million tons, of which chemical fiber accounted for 84.23%, taking the leading position. with the rapid development of the industry and the rapid increase of consumption, the disposal of waste chemical fiber textiles also comes along. it is estimated that by the end of the 13th five-year plan period, china's waste chemical fiber textile production can reach nearly 200 million tons, but china's textile recycling rate is less than 10%, compared with developed countries, there is a significant gap.
waste chemical fiber textiles are treated as waste for simple disposal such as landfill or incineration, which not only seriously pollutes the environment, but also causes great waste of resources. seeking for recycling has become an urgent need for the development of china's textile industry.
according to chinese academy of engineering shi-cheng jiang, in order to promote the benign development of industry of our country chemical fiber regeneration and comprehensive upgrade, the chinese academy of engineering in 2017 to set up the "waste resource recycling technology development strategy research, chemical fiber textiles" consulting project, led by member of textile fields, relying on the donghua university, and invite the experts in related academics, representative enterprises such as more than 40 people involved in the research. it took more than a year to form the research report and the suggestions of academicians.
"chemical fiber recycling is an important direction of chemical fiber industry in the new era." hua-ping wang project's secretary-general said that in the next 10 years, with "zero dumped, clean and low carbon, high efficient high-quality value" as the guide, with major project of science and technology as the gripper, to "administration, production, study and research, with" independent innovation system construction as the support, to establish scientific research and national textile recycling engineering technology development platform, make our country of polyester, polyamide, polypropylene, pps key chemical fiber varieties such as recycling technology and the innovation ability among the world's highest.
on this basis, the project puts forward the key tasks. one is the research on the basic science of waste chemical fiber material regeneration; second, waste chemical fiber textile rapid identification and sorting technology; third, waste chemical fiber textile pretreatment and resource standardization; fourth, the key technology and industrialization upgrade of mechanical and physical method regeneration; fifth, the key technology and industrialization of physicochemical method regeneration; sixth, the key technology and industrialization of chemical process regeneration.
at the same time, the project formed three special recommendations. first, build a modern recycling logistics system for waste textiles. under the national related department to coordinate with local government and professional structure, set up textile logistics technology and equipment purchasing list, the government special allowance form, form system complete, fully functional, management, operation and orderly old chemical fiber textile recycling logistics industry chain, which is based on modern returned logistics information platform construction, gradual smart recycling bins, professional logistics and distribution station construction, built in 200 km recycling economic circle, realizing a complete coverage of returned logistics network system.
second, the construction of waste chemical fiber textile recycling industry cluster and demonstration park. we should make full use of synergies and economies of scale, optimize resource allocation, and improve the efficiency of resource utilization, so as to form a radial driving force by combining point-to-point and point-to-point, and promote the recycling and recycling industry of waste chemical fiber textiles to achieve rapid progress.
third, the construction of waste chemical fiber textile industry and research innovation and display platform. it is suggested that the state set up a special state key laboratory for recycling and recycling of waste textiles and a national engineering technology research center, strengthen the construction of scientific research and talent platform, and accelerate the in-depth research on chemical fiber recycling and the transformation of research results.
