6. End-of-life management for polyurethanes

PU materials are designed for long-term applications thanks to their high-strength urethane bonds. However, these properties can lead to the accumulation of persistent waste in the environment if PU materials are not properly disposed of. PU consumption generates around 3 Mt of PU waste every year in Europe . Historically, three main methods of PU waste disposal have been used: landfill (50%), incineration (45%) and recycling (5%). With increasing waste regulations, it is important to explore new PU waste management methods...
