Steam classified municipal solid waste (MSW) has been studied for use as a combustion fuel, feedstock for composting, and cellulytic enzyme hydrolysis. A preliminary study has been conducted using a prototype plasma are pyrolysis system (in cooperation with Plasma Energy Applied Technology Inc., Huntsville, AL) to convert the steam classified MSW into a pyrolysis gas and vitrified material. Using a feed rate of 50 Ibs/h, 300 Ibs of the material was pyrolysized. The major components of this pyrolysis gas were H-2, CO, and CO2. A detailed presentation of the emission data along with details on the system used will be presented.
