Sustainability in remediation

Across the world, communities are struggling with the effects of contaminated soil and groundwater and the risk to the environment and human health. Choosing a sustainable approach to remediate contaminants that won’t contribute to climate change is key to solving these challenges..

REGENESIS provides sustainable in situ remediation solutions. Our technologies enable environmental professionals proven solutions that reduce the environmental impacts of their projects and lower the carbon footprint of their clients’ supply chain. 

Sustainability study confirms lower greenhouse gases, zero waste and less than 1/3 the cost

A recent study compared pump-and-treat systems to in situ remediation using colloidal activated carbon confirming an in situ approach emits 98% fewer greenhouse gases, uses 95% less raw material, generates zero waste, and cuts total costs by nearly 60%—all while minimizing ecological disruption and supporting long-term environmental resilience.

Sustainability case study

PFAS

We asked Ramboll’s circular solutions and climate specialist team to undertake a comprehensive sustainability study comparing our approach to pump & treat. This focused on an international airport where a PlumeStop® barrier is being used to remediate PFAS contamination. The study includes crade-to-grave Life Cycle Analysis, Life Cycle Cost Analysis and a Tier 2 sustainability assessment. The results are clear:

1 Sustainability of in situ and ex situ remediation of PFAS contaminated groundwater (15.05.2023); Ramboll; using ‘cradle to grave’ carbon footprint analysis, full product-level Life Cycle Analysis, Life Cycle Cost Analysis and Sustainability assessment using Ramboll’s SURE model (Tier 2 assessment in line with ISO, ASTM standards and SuRF-UK guidance)

Sustainability case study

Chlorinated solvents

The Danish Environmental Protection Agency published a report analysing the sustainability of an in situ PlumeStop treatment of a chlorinated solvent plume using Life Cycle Analysis and a Tier 2 sustainability assessment. The approach was then compared to a potential pump-and-treat system and shown to be much more sustainable across all parameters.

Read the report to learn why PlumeStop came out as the most favourable remediation option.

Sustainability case study

Petroleum hydrocarbons

This case study describes the voluntary remediation of an impacted operational petrol filling station in the UK where high levels of dissolved phase contamination was shown to be migrating beyond the site boundary.

Environmental consultancy SLR Consulting concluded that the most sustainable remedial design for the site would be the installation of an injectable permeable reactive barrier (IPRB) using PetroFix®. Compared to a source excavation approach, the project prevented up to 55 wagon loads of soil disposal. Substantial energy savings were also made when compared with operating a groundwater treatment plant.
