Finland Develops New Technology To Boost Waste Textile Recycling

According to the Finland VTT technology research center, the dissolution of waste textiles provides an opportunity to reuse large quantities of waste materials for textile production. The new technology can recycle cellulose fiber textiles, not only breaking through the limitation of landfill disposal, but also promoting the effective utilization of materials.

The directive adopted by the European Union in 1999 contains quantitative restrictions on the gradual disposal of degradable wastes that are stacked in landfills. EU countries must make decisions on the future disposal of textile wastes. Finland has introduced regulations to terminate the dumping of textile wastes and will take effect from January 1, 2016.

In view of the treatment of textile waste, Finland is actively studying new industrial solutions. The VTT Technology Research Center's report shows that the fabric that is worn or even stained with a lot of stains can be obtained as good as the original or better than the original.

although textile The reuse and mechanical recovery methods reduce the environmental burden, but the bulk textiles containing poor or badly stained materials limit the opportunity for recycling. The new method has increased the possibility of textile waste utilization, the Finland VTT technology research center. Ali Harlem Yu The professor pointed out.

For high value products, textile recycling saves raw materials. The premise of functional recovery is a system for effective recovery and utilization of textiles for environmental considerations. "Early consideration of recycling is very important at least in the planning stage." Anna-KaisaAuvinen, managing director of Finland textile and Garment Industry Association (Finatex), said.

Anna said: "when the textile and garment industry, consumers and other stakeholders work together to build a voluntary and practical recycling system, the best results will be achieved. We have convened Finland There is a common desire for the development of textile recycling solutions.

VTT, Artaud University and Tampere University of Technology jointly develop new regenerated textile fibers in the "cellulose design world" project (a major technological development project of Tekes, Finland national technological innovation Bureau).

At present, scientists are working on the method of separating cellulose molecules from waste textiles such as cotton by means of highly efficient and environmentally friendly solvents. There are several ways to dissolve cellulose. They have made remarkable progress in the past 10 years. One of them is the Ioncell-F method of Artaud University, which uses the ionic solvent developed by University of Helsinki. VTT's role in the project includes cleaning large staple textiles and preparing suitable forms of cellulose for solvents. Artaud university is responsible for developing the spinning process.
