One manufacturer has patented a process that breaks down polyurethane into polyol using industrial waste or scrapped automotive parts; glycolysis processes are being used that generate polyol for use in automotive seating foam and cushions for furniture and bedding. In this process, polyurethane is pulverized into powder and then is heated in a reactor at 392° F (200° C) with glycol, which converts it into a raw material. During the reaction, chemical cleavage of the polymer chains (urethane) takes place. The foam rubber industry will continue to investigate methods for reducing and recycling scrap. One manufacturer is investigating a process for directly producing molded foam parts from shredded flexible polyurethane foam trimmings and production scrap.

Most foams consist of the following chemicals: 50% polyol, 40% polyisocyanates, and 10% water and other chemicals. Polyisocyanates and polyols are liquid polymers that, when combined with water, produce an exothermic (heat generating) reaction forming the polyurethane. The two polyisocyanates most commonly used are diphenylethane diisocyanate (MDI) and toluene diisocyanate (TDI). Both are derived from readily available petrochemicals and are manufactured by well-established chemical processes. Though MDI is chemically more complex than TDI, this complexity allows its composition to be tailored for each specific application. MDI is generally used in rigid foams, whereas TDI is typically used for flexible foam applications. Blends of MDI and TDI are also used.
