Open the CIPO recordAbstract From the Canadian patent
Vent structures are provided on the upper and lower sides and lid of an organic waste cart so that wet biomass deposited in the cart is dried by convective air currents passing through the cart. The lid vent is hooded to prevent moisture from passing into the biomass. A perforated false bottom within the cart elevates the biomass above the lower vents to assure that drying air can circulated throughout the biomass.

Why it's free to use
- Filed November 10, 1998 and granted August 7, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 10, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 10, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
