This technology was developed in cooperation with DEKONTA as the main partner within a research project co-financed by the Ministry of Industry and Trade of the Czech Republic (project FR-TI1/237). The result is an in-situ remediation method utilizing the biodegradation potential of indigenous microorganisms to treat rock environments contaminated with trinitrotoluene (TNT). The technology’s effectiveness was validated through two pilot-scale applications at a real contaminated site.
