RECYCLING OF RIGID POLYURETHANE WASTE – A COST REDUCTION STRATEGY IN RIGID POLYURETHANE FOAM PRODUCTION
With the surging demand for rigid polyurethane in worldwide as insulation material against increasing temperature, a large number of polyurethane foam wastes need to be disposed. There are mainly four types of disposal technology, landfill, incineration and recycling in the world. This research work presents recycling of rigid polyurethane foam waste as an input in the production of sandwich panels. This method ensures a huge cost saving in the rigid polyurethane sandwich panel production process while waste reduction is also achieved in large volume.
