A firebox apparatus is adapted for transport on a vehicle having a roll-off hoist mechanism by providing parallel guides on the underside of a supporting skid assembly of the firebox apparatus for engaging siderails of a tiltable roll-off track of the hoist mechanism, and by providing reinforced front and rear portions connecting parallel longitudinal skid members to maintain an opening at the bottom of the firebox apparatus yet make the firebox apparatus sufficiently sturdy to withstand loads encountered during loading an unloading from the transport vehicle. The firebox apparatus includes an air curtain system for limiting pollution resulting from incineration of waste. The present invention enables easy installation and removal of the firebox apparatus in crowded environments, such as urban environments, to cleanly burn waste.
