: The PU (Polyurethane) is a very versatile industrially material, however a large volume of waste of PU is disposed on landfills every year. But the process mechanical recycling can be a sustainable and environmentally friendly alternative. This work searches the development of agglomerated boards of industrial waste of polyurethane skin (PUs) with the addition of different non-halogenated flame retardants, as well as your evaluation of reaction to fire. The compositions used were 40-50% (wt.) of industrial waste of PUs, 30% wt. of PU resin and 20-30% wt. of different non-halogenated flame retardants. It was evidenced that the agglomerated boards with 30% APP (ammonium polyphosphate) showed the best result of reaction to fire, classified as V1 based on UL94 V Standard. The agglomerated boards with flame retardants represent good alternative to PU’s waste recycling, and may be used, for example, in revetments or panels for thermic and acoustic insulation for building construction.
