Abstract

The general class of polymers are polyurethanes (PU), which are prepared by the polyaddition of isocyanates and hydroxyl groups of different compounds. Polyurethane linkages are formed by the reaction of poly-isocyanate and multi-functional hydroxyl compounds and results polyurethane foam. The foams have wide range of densities and may be flexible, semi-flexible or rigid in nature. The blowing agents are responsible for the structure of foam and are introduced during foam formation through volatilization of low-boiling liquids or through the formation of gas due to chemical reaction. Besides these agents, surfactants, catalysts, etc. are also used during the manufacturing of foams. This polymeric material is the most important for making different types of daily need items. Therefore, it is essential to recycle the wastes of it. There are so many methods to recycle the wastes of polyurethane, but no methods have yet been of commercial purpose and regular practice. The objective of our study is to develop a new sustainable technology of recycling the wastes of polyurethanes.
