RESEARCH & DEVELOPMENT

As part of its treatment activities, Northex mission is to recycle more than 65% of treated soils in engineering works, earthworks and ultimately even for agricultural purposes. Rather than investing in transportation and disposal of soils in landfills, the company decided to invest in new treatment technologies until reaching a level allowing the use of land for different purposes. To achieve this ambitious goal, the company has carried out since its beginning an intensive research and development (R&D) program to develop new processing techniques.

After working on several different treatment projects, the results of our work indicate that there is no single solution for the treatment of contaminated soil. In this context, we need to consider an approach where more than one technical and procedural contribution is used to remove organic and inorganic contaminants. Northex couples washing techniques, segregation and extraction to allow recovery of treated soil. These techniques and technologies must be demonstrated at laboratory scale before being deployed commercially. Research and development of new techniques is necessary to collect operational data in the lab before transposing the technology on an industrial scale.

Other research projects are carried out in our laboratories in order to find uses for the treated soils. To this end, the treated soil has economic value and Northex is developing projects also aimed at manufacturing products from treated soils for the agricultural sector, road improvements, etc. The treated soils can be amended with different sources of organic carbon and nutrients (compost, fertilizer, etc.).

The research and development department has a team of engineers, geologists and experienced technicians, who worked together to find the best solutions to revitalize the earth.
