Low-cost Textile Recycling Process
PACE Partners the Government of Canada is contributing to the following Calls to Action from the Circular Economy Action Agenda for Textiles
7. Increase efficiency and quality in textile sorting
8. Make the recycled fibers market competitive
The Government of Canada, through the Canadian Plastics Innovation Challenge, is financing Met-Tech’s project to develop a comprehensive solution for recycle of waste textile materials that minimizes labor, energy, and capital inputs and uses closed-looped processing technology for the recycle of chemical solvents. Specifically, it consists in developing a low-cost textile recycling process for chemical sorting, separation and removal of dyes from waste textiles for (1) the recovery of a pure polyester product and (2) the conversion of cotton, viscose, rayon, and other cellulosic based materials into high value, nontoxic, biodegradable biopolymers. Moreover, the chemicals used to treat the textiles are internally continuously recycled.
Through this action, Canada aims at improving the textile waste sorting efficiency and recycling profitability since materials would not need to be pre-sorted and the combined physical and chemical separation would allow to keep low labor input costs and streamlining downstream material recovery steps while increasing the value of cellulose based materials.
Objectives for 2021
The Met-Tech Inc. Low-cost textile recycling project is currently at the stage of proof of concept, which is expected to be completed in July 2021. The next steps will consist of securing and initiating prototype development work by the end of 2021, after which, if successful, a pilot project may be conducted.
