Open the CIPO recordAbstract From the Canadian patent
A waste collecting and recycling system where a portable waste sorting apparatus is located at a first collecting location. Waste from a nearby locality is brought to the collecting location where the recyclable material is sorted out and carried to another location for recycling or possibly further shipment. Then the portable separating apparatus is moved to a second collecting location and the process is repeated. The waste material brought to these locations can in some instances be presorted, with further sorting or separation being accomplished at the collecting locations. Thus efficiencies are realized in transportation costs and also in effective use of the sorting apparatus.

Why it's free to use
- Filed April 10, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 10, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 10, 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.
