New concept for valorisation of the polluted grounds and waste

Kurzfassung

A French company develops research and development for valorisation of the polluted grounds and waste. It proposes the management of the polluted grounds, materials resulting from these wastes but also the sorting and the waste disposal resulting from wild discharges. The various dies retained for the polluted grounds and materials resulting from the buildings public work support the valorisation of waste while based on the analytical results tests. The company looks for technical collaboration.

Details

A French company develops a pole of research and development studies the properties with the leaching of various compounds in order to, as well as possible manage the polluted grounds and waste of the buildings public works. The tests of leaching and percolation realised respect the physicochemical characteristics of the future conditions of storage: pH, salinity, temperature, duration of contact of their future use.
The innovating step allows the valorisation of some materials through theirs re-use in various harbour, road work or public constructions. It contributes to limit the systematic storage of this type of materials, emerging in the more or less long term with the saturation of the various rubbish dumps.
In order to be autonomous and to be able to carry out this kind of studies, a laboratory specialised in the characterisation of waste at summer set up, it proposes only tests of leaching and tests of percolation, this with an aim of being able to carry out the potential test polluting, according to the obligation relating to the elimination of the blast-furnace slag and the necessary storage of dangerous waste.
The process is based on several innovative materials: posts of percolation according to several norm "characterisation of waste, tests of behaviour to leaching, test of percolation to ascending flow" and posts leaching according to "characterisation of waste, leaching, conformance testing for leaching of fragmented waste and mud".

Innovative Aspects:
- Tests carried out under real physicochemical conditions of the material's future use.
- Solution for polluted ground re-use instead of systematic storage in discharges.
- Autonomous pole.
- Financial reduction of the costs of depollution for example of polluted grounds.
- Financial reduction of the management of wild discharges.
- Better approach of the dangerosity of materials.
