One of the best-equipped final disposal sites in the country, this facility makes use of the latest technology and combines environmental friendliness with safety.
In 2007, as a host of environmental problems were coming to the fore, we constructed a large controlled landfill disposal site. Having a landfill surface area and volume roughly equal to the size of Tokyo Dome, this controlled final waste disposal facility is on a sufficient scale for our planned long-term operations.
Constructed in October 2019

DSC (Direct Spray Control) Process
It is not only the scale of this controlled landfill disposal site that matters. A further priority for Oono Associates is reliability, which is why we have utilized the DSC process. DSC uses polyurethane resin (rapid-curing sealant and cushioning sealant) sprayed directly on to a mortar undercoat. Bonding tightly to the mortar, the resin forms a robust, impervious layer.
