Thermoset polyurethane (PU) products such as flexible and rigid foams are long-lasting, durable and useful in many different applications. They are among the six most important plastic materials produced worldwide and promote comfort and safety in daily life. Compared with thermoplastic materials, recycling thermoset PU is a much more challenging process.


Polyurethanes are very versatile materials and are used in a large variety of applications:

  • Construction materials mostly as thermal insulation
  • Appliances
  • Furniture and bedding
  • Automotive & transportation such as car seats, headliners, acoustic products, instrument panels, headrests etc ..
  • Footwear
  • Coatings, adhesives, sealants and elastomers
  • Binders

Recycling of polyurethane foams is primarily done on post production waste by a mechanical recycling process. Foams are chopped in small pieces and compressed with a binder in the rebond process. These recycled products find applications in carpet underlays, shock absorbing mats and acoustic products. The outlet markets are relatively limited and saturated.
