Metal oxide Aided Subsurface Remediation: From Invention to Injection

Project description

Novel metal oxide reactants support cost-effective soil and groundwater remediation

Polluted water and soil are leading causes of death worldwide. With increasing water scarcity, remediation becomes an even more pressing need. Toxic chemicals and organic solvents are key sources of soil and groundwater pollution throughout Europe and abroad. Current technology for remediation is costly and disruptive. With the support of the Marie Skłodowska-Curie Actions programme, the METAL-AID project will train 14 early stage researchers in projects to develop technologies to decontaminate soil and groundwater directly underground. Focusing on known and new metal-oxide reactants, the team will develop models for safety assessment, as well as quantify effectiveness in the lab and at field sites.

Objective

Thousands of sites across Europe are polluted with toxic metals and organic solvents; many more exist worldwide. As EU population grows, clean water will determine the quality of life and economic stability. Most sites remain contaminated because existing technology is costly and disruptive. Society needs an innovative way to decontaminate soil and groundwater directly underground. In METAL-AID, we will develop new technologies through fundamental knowledge.

We are a consortium of experts in natural materials, contaminant reactivity, groundwater treatment and environment policy, spread over 4 consulting firms, 6 universities and a government agency. We will train 14 early stage researchers (ESRs) through integrated, intersectoral research, using advanced technology, ranging from nanometre to field scale. ESRs will gain technical, business and personal skills, as they push a promising soil and groundwater remediation technology toward commercialisation. To meet the METAL-AID goals, the ESRs will:

1) Test known layered double hydroxide (LDH) and redox active green rust (GR) reactants that show promise for remediating toxic metals and chlorinated compounds and invent new ones;
2) Derive thermodynamic and kinetic data, essential for safety assessment modelling;
3) Quantify reactant effectiveness and reacted phase stability and compare these with natural analogues;
4) Inject the new reactants at field sites operated by our beneficiaries.

METAL-AID begins at technology readiness level, TRL 1 and runs to TRL 6, implementation. The government agency will provide guidance so our new technology complies with regulations and has promised R&D funding after the ETN ends, to carry it into full commercialisation. The ESRs will be trained to tackle challenges of concern to society, to communicate across sector boundaries and with the public, in a network that will last long after the project ends. We will provide a pool of scientists for roles in EU's knowledge based economy.
