Pilot tests for new bioremediation method for PAH-contaminated soil

We are doing pilot tests with Ragn-Sells AB in Häradsudden, Norrköping, to develop a modular and mobile solution for treatment of PAH-contaminated soil, by using our microbial products with Archaea.

The aim of the project is to develop an innovative and cost-efficient biological treatment technology that is fully based on natural degradation processes of contaminants and to stimulate this method through mixture with renewable resources (e.g. waste from the forestry and pulp industry).

Initial results have shown that breakdown of polycyclic aromatic hydrocarbon (PAH) is between 40-60% in the contaminated soils. Further investigations have to be done on the mixing process and to optimize the blending facility as well as to ensure the efficiency and compare the cost of alternative treatment options in large scale.

Remediation time to reach an acceptable level of PAH so that the masses can be put on landfill for non-hazardous waste

The pilot tests have been financed by Vinnova through the program Innovative startups.
