Definitions
- the present invention relates to the field of packaging waste.
- the term "waste” is used within the meaning of European Directive 2006/12 / EC of April 5, 2006 and designates any substance or object which falls under the categories listed in Annex I to this Directive, which the holder discards or which he intends or has the obligation to dispose of.
- It relates more particularly to the conditioning of waste resulting from asbestos-removal work for buildings or public works.
- EP 3 133 033 relating to a flexible packaging of solid waste with a capacity greater than 5 m 3 , consisting of a mechanically resistant outer casing and an inner casing dustproof, each comprising a cover which can be closed on a pocket by closing means so as to close the packaging in a leaktight manner using a system of flaps extending from the upper peripheral edge of the packaging, interposed between the outer envelope and the inner envelope and covering the means for closing the inner envelope.
- Such packaging is well suited for homogeneous waste of the milled type, polluted soil or steelworks dust, with a small particle size.
- the flexible containers conditioning the waste are placed in a metal skip during their loading and transport.
- Some skips can be unloaded, on the storage site, from the transport truck, in particular using an articulated arm of the Ampliroll® type, requiring a slight inclination during dumping, which allows to preserve the integrity and therefore the tightness of the container.
- the metal container with a capacity of 32T housing the flexible container remains attached to the transport truck and a tilting of the container to unload the flexible container with the waste is carried out.
- the tilt angle is large, in other words the inclination of the bucket during dumping is large, which results in sudden unloading and greatly increases the risk of damaging the flexible container.
- waste management particularly asbestos
- the waste is often made of scrap metal and large blocks, or earth mixed with other stone-like materials, concrete blocks, pieces of fiber cement pipe, which increases the risk of tearing or piercing the containers and ultimately of destroy the seal. It is thus necessary, before packaging the waste in the containers, to pass it to the screening to sort it and / or break the excessively bulky waste into smaller pieces, which generates significant processing costs.
- the present invention manages to solve all or part of this need and relates to a flexible container for packaging waste comprising:
