GRANULATION RECYCLING OF POLYURETHANE REMNANTS AND CONCRETE REMNANTS BASED ON AGGREGATE OF LIGHTWEIGHT EXPANDED GLASS

摘要

A procedure of recycling of waste polyurethane and concrete remnants based on aggregate of lightweight expanded glass, where a new liquid polyurethane or concrete phase is added in a mould, reduces the accumulation of building wastes on building sites and municipal landfills, decreases the costs of building waste disposal and at he same time enables the manufacture of new auxiliary insulation products and reduces the consumption of starting raw materials.
