Daiseki Eco Solution Co.

What Daiseki Eco Solution Co. does

Daiseki Eco Solution Co., Ltd. (株式会社ダイセキ環境ソリューション, TYO: 1712) is a Japan-domiciled, Tokyo Stock Exchange Prime Market-listed environmental services company headquartered in Nagoya, Aichi Prefecture. Founded in 1996, the firm operates as a nationally designated survey institution (国的に指定調査機関) authorized to conduct official soil contamination investigations under Japan's Soil Contamination Countermeasures Act. Its core business is a one-stop soil contamination solutions platform covering consulting, site investigation via historical land-use research (地理調査), in-house chemical environmental analysis (pH, SS, VOC), purification engineering and treatment, and material recycling at company-owned facilities. Major operational sites include recycling centers at Yokohama Ebi/Menomagi, Yatomi, Gifu, plus the subsidiary-led Shizuoka facility operated by Green Arrows Chubu; the Tokyo Division provides technical supervision for the Kantō metropolitan market.

The company monetizes primarily through B2B professional-services contracts with construction companies, real estate developers, and public-sector clients requiring pre-construction contamination surveys and remediation under Japanese law. Secondary revenue streams include polychlorinated biphenyl (PCB) waste processing operated by a dedicated department, sale of environmentally conscious products (notably biodiesel fuel produced via a world-first separation membrane process launched June 2024, and recycled soil solidification materials), and disaster-waste handling services delivered under municipal partnerships (Toyokawa City 2023, Aichi Prefecture and Nagoya City in 2024). Distribution is direct enterprise field sales with technical staff participating in client meetings to advise on remediation approach. The company holds wholly-owned operating subsidiaries Green Arrows Chubu and Green Arrows Kyushu, extending its geographic reach and disaster-response capacity beyond Nagoya headquarters.

The firm pursues a sustainability-led positioning with active ESG disclosure (selected Environmental Disclosure Progress Company at the 5th ESG Finance Award Japan, 2024), certification by Japan's Ministry of Health, Labour and Welfare (Eruboshi 2-Star, 2026) for women's workplace participation, and Health Management Excellent Corporation 2026 recognition by METI/Japan Health Conference. Pricing is not publicly disclosed; financial scale figures in the source appear inconsistent with reported headcount (101–250) and cannot be reliably triangulated without restated disclosure.
