Composition for manufacturing eco-friendly mat, manufacturing method of eco-friendly mat, and eco-friendly mat

A manufacturing method of eco-friendly mat, comprising the steps of:

• a) recycling step:
• collecting recycled insoles or collecting recycled insoles and at least one of waste generated during the production of TPU and/or EVA copolymer and offcuts generated during the production of insole pads, to obtain recycled materials, wherein the recycled insoles comprise pads and fabrics attached to the pads, the pads are made of TPU and/or EVA copolymer, and the fabrics are made from at least one selected from the group consisting of plant fibers, animal fibers, and synthetic fibers;
• b) shredding step:
• shredding the recycled materials to obtain recycled polymer scraps having an average particle size between 0.3 mm to 5 mm and recycled fiber scraps having an average fiber length between 0.3 mm to 5 mm;
• c) heating and mixing step:
• heating and homogeneously mixing the recycled polymer scraps, the recycled fiber scraps, and a polyether-based adhesive to obtain a composition, wherein
• based on 100 parts by weight of the polyether-based adhesive, the composition comprises 260 to 340 parts by weight of the recycled polymer scraps and 10 to 100 parts by weight of the recycled fiber scraps;
• and
• d) cooling and molding step:
• introducing the composition into a mold, cooling to solidify the composition, and demolding to produce an eco-friendly mat.
