A business model centered on in-situ and on-site remediation as core competitive advantages

「Soil contamination remediation business (now the Environmental Solutions Business); expanding orders by providing an integrated solution from risk assessment through in-situ remediation; advancing the construction model through coordination with risk assessment and the use of DX; deploying PFAS groundwater remediation methods and bringing water treatment capabilities in-house.」

「We will expand soil contamination remediation into the Environmental Solutions Business and seek to increase revenue by differentiating ourselves through innovative remediation technologies, PFAS response technologies and consulting capabilities.」

「In the soil contamination remediation business, we are advancing initiatives including proposals for risk-based methods and performance-guaranteed construction, thorough construction quality, cost and schedule management, and improved operational efficiency through DX.」

「For the in situ permeable reactive barrier method, we received and completed an order for a project subsidized under Tokyo’s program.」

「We are focusing on differentiated proposals, including economical countermeasures aimed at managing soil contamination, known as risk-management methods; cost-cap guarantees, under which soil surveys and countermeasure work are provided as a package with the total countermeasure cost guaranteed; and the in situ permeable reactive barrier method, or Plume Stop method, which Tokyo certified as a recommended technology under its “Groundwater Contamination Expansion Prevention Technology Support” program. For the in situ permeable reactive barrier method, we received an order for a project subsidized under Tokyo’s program.」

「The first project using the in situ permeable reactive barrier method, newly introduced from a US company as a leading risk-management method for prolonged groundwater contamination at operating factories, was completed successfully. A hybrid method combining our in situ chemical oxidation technology with the Plume Stop method has been certified as a recommended technology under Tokyo’s “Groundwater Contamination Expansion Prevention Technology Support” program.」

「For the in situ permeable reactive barrier method, newly introduced from a US company as a leading risk-management method for prolonged groundwater contamination at operating factories, the first project is currently under construction. A hybrid method combining in situ chemical oxidation technology held by 株式会社エンバイオ・エンジニアリング with the Plume Stop method has been certified as a recommended technology under Tokyo’s “Groundwater Contamination Expansion Prevention Technology Support” program.」

「As more customers seek alternatives to complete remediation, we are focusing on differentiated proposals, including economical countermeasures aimed at managing soil contamination, known as risk-management methods, and responsible construction in which soil surveys and countermeasure work are provided as a package with the total countermeasure cost guaranteed.」

「For this service, we provide customers with soil contamination countermeasures that offer low cost, a short construction period and low environmental impact by combining proposals based on the method known as “in situ remediation,” which breaks down contaminants underground without excavating contaminated soil, the method known as “on-site remediation,” which excavates contaminated soil, breaks down and removes contaminants on site, and then backfills the soil, and the conventional “excavation and removal” method.」

「We are focusing on differentiated proposals, including economical countermeasures aimed at managing soil contamination, known as risk-management methods, and responsible construction in which soil surveys and countermeasure work are provided as a package with the total countermeasure cost guaranteed. However, the order environment remains unpredictable.」

「Orders increased for countermeasure methods aimed at managing soil contamination rather than achieving complete remediation, referred to below as “risk-management methods.”」

「Because contamination remains in place under management-based methods, coordination among stakeholders, including business owners, nearby residents and financial institutions, is essential. Going forward, we will focus on developing personnel with strong consulting capabilities who can handle such projects and seek to expand orders.」

「Orders for countermeasure methods aimed at managing soil contamination rather than achieving complete remediation increased, resulting in a substantial increase in profit. Management-based methods are also recommended from the environmental perspective of achieving decarbonization and are expected to become mainstream in the future. Although demand for complete remediation remains strong, the proportion of management-based methods is expected to increase going forward.」

「Through on-site construction, we have established proprietary countermeasure technologies, including in situ thermal treatment capable of addressing highly difficult soil contamination that cannot be handled with current soil remediation technologies, as well as chemical oxidation, bioremediation and adsorption technologies.」

「The number of new survey projects has almost recovered, so new countermeasure projects are expected to increase going forward. However, customers remain cautious about large-scale projects, and the impact of COVID-19 continues to affect order values. Profit margins, meanwhile, showed no significant change. To secure a stable order pipeline despite the uncertain outlook, we are strengthening our structure, in cooperation with business partners and group companies, to increase comprehensive proposals that include construction work and to actively win orders for work related to public projects.」

「Some projects also combine soil contamination countermeasure work with construction work at the site, and we are strengthening our structure to increase proposals related not only to surveys and countermeasures associated with conventional business closures but also to land development.」

「In addition to surveys and countermeasures based on conventional laws and regulations, the number of technically demanding projects is increasing, including projects using methods aimed at preventing contaminant migration and surveys of oil contamination using direct-sensing technology.」

「Since the early stages of the soil contamination issue in Japan, our group has sought to outperform competitors through its track record, treating as a core competitive strength its technical capabilities in the highly economical “in situ and on-site remediation” methods introduced at an early stage, which remediate soil on site without excavating or removing contaminated soil off site.」

「We focused on developing new customers and demand, centered on stronger proposal capabilities, including the in situ thermal desorption method, and the introduction of warranty services, among other measures.」

The design work for the first in situ thermal desorption project was completed, and production of the aboveground treatment equipment began. We also received and completed an order for an in situ immobilization project involving heavy metals.」

「We also received an order for an in situ immobilization project involving heavy metals. The related revenue will be recognized in the third quarter.」

「We provide services and products to companies that need to address soil contamination, which has become widely recognized as a significant risk in real estate transactions and development. While competitors primarily provide services based on the high-cost method of “excavation and off-site removal” of contaminated soil, our group primarily provides services and products based on “in situ and on-site remediation,” which enables soil to be remediated on site without excavation or off-site removal. We propose soil contamination countermeasures characterized by lower costs, shorter construction periods and lower environmental impact than methods such as excavation and off-site removal.」
