• In this study, the pyrolysis characteristic of waste paint dregs has been investigated by comparing with wood chips at 500°C, 700°C and 900°C with a laboratory-scale reactor. The results showed that the gaseous yield significantly increased for waste paint dregs than that for wood chips with increase of pyrolysis temperature. Therefore, it is possible to gasify waste paint dregs like wood chips at high temperature to obtain efficient combustible gas for a dual-fueled engine. And the behaviors of heavy metals in the waste paint dregs were also investigated. It showed that Pb was volatile, Ti and Zn were non-volatile in the temperature range of 500°C∼900°C. Then, demonstration gasification and power generation experiments were carried out by a plant of commercial scale, using waste paint dregs and wood chips as fuel. The results agreed with the laboratory experiments, namely the heating value of pyrolysis gas produced from waste paint dregs increased with increase of gasification temperature, while that produced from wood chips didn't increase significantly with increase of gasification temperature. Pb was also volatile as in the laboratory experiment. The power generator efficiency of the diesel engine was 34% when the energy input ratio of fuel gas produced from waste paint dregs was 60%.
