The soil particle solidification method is a system that modifies construction sludge and construction-generated soil by adding solidifying agents and polymer coagulants.

Cured treatment soil is neutral (in the neutral range) and granular, making it suitable for vegetation, and the treatment is carried out using a high moisture soil solidification recycling system. Using a solidifying agent in the neutral range (pH=5.8–8.6: Water Pollution Control Law) (AC High Cure, Eco Hard A), high moisture soil is processed into granular solid form. Since gypsum (hemihydrate gypsum) is the main component and solidification occurs quickly, it requires almost no curing period. 【Features】 - Gypsum (hemihydrate gypsum) is the main component, and solidification occurs quickly, requiring almost no curing period. - The treated soil is neutral and granular, making it suitable for vegetation. - The treated soil is not toxic to fish. *For more details, please refer to the related link page or feel free to contact us.

This method uses a pH neutralizer (Dr.pH for sludge) to neutralize strongly alkaline soils such as improved soil and self-hardening sludge. After mixing the target material with the neutralizing agent, the pH value stabilizes in about 3 to 7 days. It complies with soil environmental standards, and the applications for self-hardening sludge and similar materials expand after neutralization. 【Features】 ■ The pH value stabilizes in about 3 to 7 days after mixing the target material with the neutralizing agent. ■ The applications for self-hardening sludge and similar materials expand after neutralization. ■ Complies with soil environmental standards. ■ Performs neutralization treatment of self-hardening sludge and lime-improved soil. *For more details, please refer to the related link page or feel free to contact us.

Our company is currently developing a recycling-type solidifying agent using waste gypsum boards. The recycling products made from waste gypsum boards require processes to return them to calcium sulfate and technologies for insolubilization, among others. Waste gypsum boards contain a high amount of fluoride, which has posed challenges for recycling; however, we have achieved insolubilization using special additives. As a result, we expect cost benefits compared to conventional products. *For more details, please refer to the related links page or feel free to contact us.
