Canndure is a revolutionary new odour control technology that eliminates odour in waste holding tanks. Unlike other deodorizing products that just mask odour, Canndure prevents the formation of thiol containing compounds, the root of tank odours. A little bit of Canndure goes a long way - just one ounce per five gallon capacity removes waste odours, making Canndure both efficient and cost-effective. Canndure is non-accumulative and completely biodegradable. To date, Canndure has been used for odour elimination in: Recreational vehicle and leisure marine holding tanks, Portable chemical holding tanks, Outdoor toilets, Bus and Rail holding tanks, Marine Transportation tanks, and Cat Litter Production. Canndure has been approved for use by Parks Canada and complies with municipal environmental regulations; waste can be transported directly to waste treatment centres for immediate disposal, without any further additives or wasted time. Canndure is supplied in a natural, unscented formulation.
