PFAS contamination in agricultural soils
The past application of sewage sludge has resulted in PFAS contamination of large areas of agricultural soil. This presents challenges to agriculture, authorities and consumers that have scarcely been encountered before. These persistent chemicals can enter the food chain via soil and forage crops, consequently finding their way…
Research project
PFAS in soil washing
Soil washing is currently the only internationally established industrial-scale process for treating large quantities of PFAS-contaminated soil and excavated material. The aim is to separate the contaminants from the gravel and sand, which make up most of the material, and concentrate them as much as possible in the wash water and…

tireX+ - Reduction of tyre abrasion emissions
During a one-year field trial, UMTEC is investigating and optimizing the separation system developed in the preliminary project for the removal of tire abrasion from road runoff. Due to its space-saving design, the system is particularly well-suited for use in urban areas. To assess its efficiency and cost-effectiveness in…

PFAS in Incinerator Bottom Ash (IBA)
Around 700,000 tonnes of incineration residues from municipal waste-to-energy (WTE) plants are deposited in landfills in Switzerland in the form of incinerator bottom ash (IBA) every year. On behalf of a landfill operator, UMTEC is investigating the PFAS contamination of IBA from various WTE plants, as well as the factors…

VinylMet - Recovery of heavy metals from MSWI slag
In an earlier project (VinyAcid), it was found that the dosed addition of PVC sorting residues in MSW incineration plants not only produces more acid but also shifts heavy metals from the slag to the filter ash. This enables heavy metals to be recovered from the filter ash.
Research project
DepoCarb - Stabilisation of slag landfills through carbonation
In cooperation with waste incineration plants and landfill operators, field tests are being carried out on the ‘artificial’ carbonation of MSWI slag. This achieves a chemically inert state (‘earth crust quality’) of the slag, so that heavy metal emissions discharged with the landfill leachate are reduced or prevented in the long…
Research project
Eco-plaster - plaster mortar made from mineral waste
UMTEC has discovered that a combination of paper ash and selected, finely ground waste materials has very good binder properties. In this innovation project, a binder formulation is being optimised for use as exterior wall plaster.

TISCAREC - Recycling of artificial turf
Tisca Tischhauser AG would like to promote the environmentally friendly disposal of the artificial turf it produces. This strengthens the sustainability of the high-quality Tisca artificial turf.
