A development is currently underway in Denmark that could transform the way we manage excavated material, sludge, and soil contamination throughout the Nordic region. Using Backer’s new mixing technology, companies have begun stabilizing roads, capping landfills, and reusing materials on-site—with a mixing precision of up to 1%.
The results have been so successful that the Danish government now sees hundreds of millions in potential savings, and the issue has reached the political level. The technology is environmentally friendly, resource-efficient, and circular—and ready to be introduced in Sweden.
Technology at a Glance
Backer’s mixing system enables continuous, precise, and reliable mixing of soil, sludge, and waste materials. Unlike traditional methods, the mixer can also handle unscreened and uneven material—without any downtime.
The system combines sorting and feeding into an integrated process that provides full control over the blending. The recipe—which may include lime, bentonite, biochar, or ash—is developed in collaboration with the customer based on the material’s properties and the desired outcome.
Applications
- Soil stabilization and soil improvement– ensures that roads, noise barriers, and construction sites remain stable even in poor soil conditions.
- Final capping of landfills– mix bentonite and soil to create impermeable, secure surface layers.
- PFAS and other contaminants– stabilize and bind hazardous substances in the soil to prevent leaching.
- Reuse of dredged material, clay, and excavated material– reduce transportation and the need for virgin material.
- Rehabilitation of contaminated industrial sites—such as old sawmills—into developable land.
Why this is important for Sweden
Currently, there is a lack of large-scale solutions for precise and continuous mixing of materials. This technology opens up entirely new possibilities for:
- reduce the amount of waste sent to landfills,
- reuse local materials,
- meet climate goals by reducing transportation,
- reduce the costs of excavation and restoration work.
Germany already has legal requirements for local waste management, and Denmark is leading the way. Sweden now has the opportunity to follow suit—with Norditek and Backers at the forefront.
Next step
Starting next week, Our will be available. We are planning demonstrations and test runs where you can see exactly how mixing works in practice.
