A sheet moulding compound (SMC) of fibre-glass and ortho-phthalic polyester has been pyrolysed in a laboratory installation at 300, 400, 500, 600 and 700 o C for 30min. Solid residues of 72-82wt%, gas yields of 6-12wt% and liquid yields of 9-13wt% were obtained. No significant influence of temperature was observed over 400 o C, however, there certainly was influence under 400 o C, both in pyrolysis yields and in the composition and characteristics of the liquids and gases obtained. The pyrolysis liquids are a complex mixture of C 5 -C 2 0 organic compounds, mainly aromatic and with numerous oxygenated compounds. They have high gross calorific values (34-37MJkg - 1 ) and are non-polluting liquid fuels. About 40% weight of such liquids could be used as petrol and the remaining 60% could be mixed with fuel oils. The gas fraction produced is very rich in CO and CO 2 . Consequently, its gross calorific values are rather low (13.9-16.4MJm 3 N); however, it can have energy source to self-sustain the process.
