Initiatives for the 3Rs utilizing new technologies. Eco-pants that regenerate nature and resources, creating an environment.
Recycled gypsum (hemihydrate gypsum) is generally a safe and harmless material used as a raw material for gypsum boards, surgical casts, dental prosthetics, food additives, and more. At "Masato Co., Ltd.," we have developed a neutral solidifying agent as one of the uses for this recycled gypsum. Recycled gypsum reacts with moisture in sludge and returns to its original dihydrate gypsum form, solidifying in the process. We kindly ask for your cooperation in utilizing this recycled gypsum solidifying material, which contributes to an environmentally sustainable society and has no impact on ecosystems. 【Features】 ○ Registered with NETIS: QS-070005; Patent No. 3980008 ○ Proven safe and harmless through environmental standard tests related to soil contamination ○ Does not contain substances that adversely affect the environment, such as harmful heavy metals, which are problematic with cement-based solidifying agents ○ Enables cost reduction by solidifying and improving construction sludge and deep soil into granular form For more details, please contact us or download the catalog.

basic information
【Features】 ○ Neutral → While cement and lime exhibit high pH and strong alkalinity, the improved soil after nationalization at Ecopa becomes neutral, making it harmless to the environment and nature. ○ No leaching of harmful substances → It does not contain substances that affect the environment, such as hexavalent chromium, which is a concern with cement-based solidifying agents, and other harmful heavy metals. → It can be used safely and with peace of mind. ○ Improvement effects are realized in a short time → The hydration time of the recycled stone is very fast, and after mixing with sludge, construction sludge can be re-resourced into improved soil of Class 4 (200KN/m²) or higher in about 3 hours. → Therefore, the curing and temporary storage periods (3-7 days) are unnecessary, and it can be transported immediately without the need for a storage area. ○ The modified soil is neutral and does not re-sludge → Because it uses a neutral solidifying agent, if the original sludge is in the neutral range, it can be re-resourced as neutral soil, preventing sludging. ○ Plant-friendly → Originally, gypsum (calcium sulfate) is used as a special fertilizer as a source of Ca and S, serving as a source of the six essential nutrients for plant growth. → It is also used to promote soil granulation and prevent salt damage. → Therefore, it becomes soil that is gentle on plants. ● For more details, please contact us or download the catalog.

Company information
Masato Corporation has been involved in the fields of civil engineering, construction, and waste management for over 20 years. However, in recent years, environmental issues have been frequently raised, and we have been plagued by the question of whether it is really acceptable to continue as we have been. The water and green earth we live on... the resources given to us by the Earth are not infinite. To effectively utilize these limited resources, the reuse of resources is essential. We are considering and implementing ways to contribute, even in small ways, by leveraging the expertise of Masato Corporation. As part of our future initiatives, we will enhance the production plant for neutral solidifying agents, EcoPant, focusing on increasing production volume and systematizing quality control. We will also establish a system for receiving orders for large-scale plants, expand our waste gypsum recycling business nationwide, and concentrate on the sales of EcoPant, primarily through manufacturing consulting. Additionally, we will continue our joint research with Nagasaki University of Science and Technology and Nagasaki University, striving to improve the recognition of Masato Corporation's products. Moving forward, all employees of Masato Corporation will work together to contribute to society through our products.
