With the wide application of polyurethane foam materials, a large number of polyurethane foam wastes need to be disposed. There are mainly three types of disposal technology, landfill, incineration and recycling in the world. In this paper, through comprehensive comparison, recycling is the most desirable way. Physical recycling method, due to the simple operation and relatively active application, in the short term is an effective means. Chemical recycling method, due to its higher technical difficulty, is difficult to realize large-scale industrialized production in the short term. And in the future, recovery utilization is the ultimate method.

• Polyurethane Foams: Past, Present, and Future (2018, background): “PUFs ́ wastes generated in production or recovered after use can be disposed in landfills or incinerated, but neither are acceptable because long-range ecological goals dictate zero pollution as well as the conservation of raw materials [159].”
