Process for the disposal of waste, ABSTRACT The accumulated waste is pressed under high pressure to form blocks or boards having high strength, low elutablity and low permeability, then packed in film individually or in stacks in a dust-tight and water-tight manner and deposited in this form on a dump like building bricks. The process can be used universally for all waste which is available as bulk material and has no coarse components, such as stones, metal pieces and the like. (Figure 3) Le A 26 291

Why it's free to use
- Filed December 13, 1989. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 13, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 13, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
