SEPARATION OF FLOOR COVERING COMPONENTS FOR RECYCLING |
摘要 |
<p>This invention relates to methods for processing floor coverings (100), such as carpet and/or carpet tile, having at least one layer containing a polyurethane (104), such that at least this polyurethane-containing layer (104) can be recycled and reused. The method involves contacting the floor covering (100) with an organic polyol (110) and heating (120) it, so that the polyurethane-containing layer (104) softens and/or partially liquefies, but can be resolidified by contact with additional polyisocyanate (140).</p> |
