Alternative Landfill Cover HR
NETIS-Registered Product
QS-230022-A(external link)
This liquid agent can be used instead of the soil cover placed over waste buried at final disposal sites. Because it contains a durable high-molecular-weight polymer, it not only prevents dust dispersal but is also expected to reduce rainwater infiltration into the waste layer. To use, dilute HR with water to the desired concentration, spray it, and then allow sufficient drying time.

Dust and Erosion Control Agent Stonewall
NETIS-Registered Product
KK-200056-A(external link)
Used to prevent dust dispersal and protect slopes at civil engineering and construction sites. The high-molecular-weight polymer coats and binds dust particles, providing long-term surface stabilisation. To use, dilute Stonewall with water to the desired concentration, spray it, and then allow sufficient drying time.

Liquid Flocculant Floc
A naturally derived liquid flocculant for water treatment. When added to regulating reservoirs or similar bodies of water made turbid by soil or mud, it causes suspended particles to aggregate and settle. Before actual use, a beaker test must be carried out to determine the optimum dosage.
Alternative Landfill Cover
HR
| Functions as an Alternative Landfill Cover Increased landfill capacity |
Reduced leachate volume | Reduced dust dispersal |
| Odour suppression | Ground stability | Suppression of pest occurrence |
|
Joint research* conducted with the Faculty of Engineering, Fukuoka UniversityWe confirmed that HR performs at least as well as the soil cover used when burying waste at final disposal sites and functions as an alternative landfill cover. |
