Commonly known as PU, polyurethane is a polymer that is used to make cushions and mattresses. It is also used as enamel for paints. Though it provides us a comfortable night’s sleep without disturbances, it disturbs our environment. Sad, but true.
PU cannot be recycled. Sometimes it is burned or simply dumped in landfills. Toxic substances like dioxins are released when PU is burned. You already know what this toxic chemical can do to us. Besides dioxins, other harmful substances like isocyanides and hydrogen cyanides are also produced.
When PU degrades, it gives out chlorofluorocarbon (CFC) that depletes the ozone layer.
