A reducing agent that safely detoxifies carcinogenic substance hexavalent chromium into non-toxic trivalent chromium using the power of biotechnology!

The patented "Improved 6-Removal" is a liquid that, when added to soil, detoxifies the carcinogenic substance hexavalent chromium into safe trivalent chromium. The ST13 strain discovered by Professor Sugiyama from Tokyo University of Technology detoxifies hexavalent chromium. Our company has commercialized it through industry-academia collaboration. We have confirmed its strength, safety, impact on pH, and reduction effect, and it has also obtained NETIS certification. (KTK-160025-A) 【Features】 ■ Detoxifies the carcinogenic substance hexavalent chromium into safe trivalent chromium when added to soil ■ Confirmed strength, safety, impact on pH, and reduction effect, and has obtained NETIS certification ■ Addresses the leaching risk of hexavalent chromium from recycled sand and recycled crushed stone *For details, please request materials or view the PDF data from the download.

basic information

■We demonstrate our strength in ground improvement work. → We eliminate the risk of hexavalent chromium leaching associated with ground improvement work using cement-based solidifying agents. Even cement-based solidifying agents referred to as hexavalent chromium-compatible types, which reduce hexavalent chromium leaching, still contain hexavalent chromium, and there is a risk of leaching due to compatibility with the soil (according to a study by a national advisory body, 1 in 25 cases). In public works, this is mandatory, and even if hexavalent chromium leaches during the pre-inspection noted by manufacturers and the cement association as a precaution, construction can be carried out using "Improvement 6 without leaching" in the design method. ■For contaminated soil due to hexavalent chromium → Soil confirmed to be contaminated with hexavalent chromium, such as leftover soil from piles mixed with cement or sites of plating and chemical factories, can be made safe simply by spreading and mixing. ■For recycled sand and recycled gravel → We also address the risk of hexavalent chromium leaching in recycled sand and recycled gravel, which contribute to zero emissions as recycled materials. By simply spreading and mixing, we can effectively utilize resources while ensuring safety and security.
