Project Type

Arsenic/Chromium Soil Stabilisation for Industrial Redevelopment

Project Summary

Delivered RemBind® products for immobilisation of arsenic and chromium contaminated soil at a former wood treatment plant being redeveloped for commercial/industrial use. Contaminated soils were successfully treated in-situ using a 5% addition rate of both RemBind® 100 and RemBind® Alum, eliminating the need for costly off-site disposal and enabling onsite reuse under paved areas.

Project Outcomes

Significant cost savings achieved by avoiding landfill disposal costs estimated to be prohibitively expensive for 1,600 tonnes of contaminated soil.
Circular economy approach implemented by beneficial reuse of alum sludge waste product and retention of treated soil on-site.
Environmental sustainability achieved through elimination of transport emissions and landfill burden while maintaining regulatory compliance.
87% arsenic reduction and >99% chromium reduction in soil leachability, enabling safe long-term retention within the redevelopment footprint.

Proven at Scale
