Abstract
In this paper, solid fuel production from waste polyurethane is proposed. Waste polyurethane was transformed thermally into a brown substance with plasticity through thermal treatment with used vegetable oil at 340-360°C for 1-2 hours. Unlike polyurethane pyrolysis, this treatment was carried out without coke formation. The vacuum residue of the reaction product melts above 140°C, and can be shaped into pellets. For example, pellets of 3.5-mm diameter have a bulk density of 0.7 and a real density 1.1g/cm3. The resulting pellets have a higher heating value of 37.5kJ/g.
