The COSIA Tailings EPA Aspiration is to strive to “Transform tailings from waste into a resource that speeds land and water reclamation”.

Technologies that help achieve this Aspiration must also have a positive environmental net effect so that improvements in tailings treatment do not result in detrimental impacts on other environmental areas. Specifically they must also have the potential to improve one or more of the following areas:

  • GHG intensity
  • Water quality
  • Impact on land and disposal management
  • Cumulative effects mitigation

In addition, tailings treatment technologies that improve environmental performance while decreasing capital and/or operating costs are important as lower cost technologies that also result in environmental performance improvements are the most likely to be commercialized.
