RemBind® is a powdered sorbent that binds strongly to per- and polyfluoroalkyl substances (PFAS) in soil, preventing them from leaching into groundwater where they can cause serious harm to the environment and human health.
The Treatment Process
RemBind is mixed in the soil at an addition rate of 1% to 3% with a small amount of water. The treatment process is complete within 24 hours and the soil can then be immediately reused onsite. Validation samples can then be collected for analysis to verify the reduction in leachability (>95% compared to the untreated soil).
Mixing Equipment
For most PFAS projects, conventional earth moving equipment such as a loader/excavator and a water truck can be used for the treatment process. For larger PFAS projects, specialised soil blending equipment can be used to process up to about 1,000 MT per day, per machine.
Proven Long-Term Stability
The long-term stability of the RemBind reaction has been successfully tested using US EPA LEAF Methods which simulate 100+ years of stability under a wide range of environmental conditions. RemBind treated soils have been independently verified using US EPA Methods 1312 and 1313, which test stability over a wide range of pH values (2−12) and repeated leaches in batch and column scenarios.
Soils treated with RemBind at a US Government site in 2018 have shown no significant PFAS leaching to date.
Full-Scale Projects
RemBind has been used to treat thousands of tonnes of PFAS contaminated soil at full-scale in North America, Europe, Australia and New Zealand with local regulatory approvals.
Worldwide
RemBind® has been used successfully at full-scale worldwide and is available through distributors in North America, Europe, Australia and New Zealand.
