A garbage processing vehicle includes a rotational fermentation drum device which is disposed on a load platform of a vehicle, for mixing garbage with aerobic microorganisms and air in a rotational drum and providing conditions favourable to fermentation. By processing the garbage in a vehicle, device installation space can be saved and the garbage can be processed during transportation. Exhaust heat of the vehicle's engine is conducted to a peripheral space of the drum and air sucked from the periphery of the engine is supplied to the inside of the drum to promote fermentation.

Why it's free to use
- Filed November 15, 1991 and granted July 7, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 15, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 15, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
