The Walloon Region alone has more than 2,500 waste dumps, presenting with varying levels of contamination (SPAQUe – 2003). This analysis proves that there is an imperative need to find technically, environmentally, financially, and politically/legally realistic solutions to the problems of landfill sites. The MINERVE project has the aim of providing an integrated solution to long-term landfill management problems by developing a methodology broken down into three closely interconnected sections: characterisation of the landfill site, optimisation of the processes of landfill mineralisation and Excavation and treatment of mineralised waste by landfill mining.
In landfill mining, CTP is working to identify and validate the methods of recovery and treatment of waste with the aim of extracting usable materials. The trials carried out have shown that it is possible to recover typical fractions, such as:
The mineral fraction which could be used in cement-bound and other materials.
The fraction consisting of light plastics, which could be processed as replacement fuels.
The ferrous or non-ferrous metal fraction, usable as such.
The project is focusing on shortening the life cycle of waste eliminated in landfill sites via mineralisation optimisation (biochemical stabilisation) and maximisation of its further use (energy, materials) via landfill mining, thus reducing its overall environmental footprint and the associated risks of contamination.
