The Nano-Bio-Rem technology, developed with funding from TAČR (project TA01021792), is based on the sequential combination of abiotic Cr(VI) reduction using nanoscale iron and microbially mediated Cr(VI) reduction. Laboratory and pilot-scale tests confirmed high efficiency in permanently removing Cr(VI) from groundwater. The technology is environmentally friendly, does not introduce harmful substances into the subsurface, and does not cause long-term adverse changes in the hydrochemical composition or microbiology of groundwater. The project resulted in a validated technology and registered Utility Model No. 28124.

The circulation system enables active and remotely controlled dosing of remediation agents into the rock environment, resulting in more uniform distribution and, ultimately, reduces rebound of contaminant concentrations. It also shortens the time required to achieve target concentrations and reduces the total amount of agents needed. Online monitoring of key parameters and remote system control allows prompt response and increased efficiency of the remediation process. The system’s effectiveness was confirmed through successful application at a site contaminated with chlorinated hydrocarbons. The system was developed with support from the Technology Agency of the Czech Republic under the ALFA 4 program (project TA04021725) and is registered as Utility Model No. 29656.

Biofer-rem remediation technology involves the application of iron microparticles and easily fermentable substrates into the contaminated geological environment. This creates favourable thermodynamic conditions for (1) both abiotic and biological reduction of chlorinated ethenes and (2) the formation of reactive FeSₓ-based minerals, which also facilitate abiotic contaminant degradation. This technology is especially suitable for sulphate-rich sites. It was developed with financial support from TAČR (project TH01030851 "BIOGEOCHEM") and tested through a long-term pilot-scale trial. The project resulted in a validated technology and a functional prototype of the remediation product.

The Thermo-bio-rem technology is based on thermally enhanced in-situ anaerobic bioremediation of chlorinated contaminants. During this process, sequential hydrogenolysis of chlorinated ethenes occurs, ultimately producing non-toxic ethene and ethane. The metabolic process is significantly accelerated by raising the temperature of the rock environment to the optimal range of 20–30 °C. A substantial portion of the energy required for heating is obtained from solar power. The technology was developed with financial support from TAČR (project TH01031225) and verified under real conditions at two contaminated sites. The outcome of the project is a validated remediation technology.

For a German client, we assessed the regulatory requirements for entering the Czech and Slovak markets as a waste trader, specifically in the area of waste batteries. In addition to applying the Waste Act, it was necessary to examine relevant legislation concerning business licensing and trade conditions in both countries.

Our SIS database for managing legal obligations has been used for several years by a number of companies, especially in the automotive sector. These include ZF Group plants, as well as ITW Pronovia, THK Rhythm Automotive, and BCS Automotive Interface Solutions. Outside the automotive industry, our database solution has also been implemented in Pragolaktos Dairy.
