Secondary Products

Program Overview

This Secondary Products Program is all about resource conservation and innovative utilization. It focuses on beneficial use of mineral-based secondary products generated by mining and other industrial activities, with an eye on their potential for value-added product development and innovative technology uses, their potential environmental impacts, and their resource conservation attributes. This is all within the context of sustainability and a circular economy.

Program Goals

  1. Maximize mineral resource utilization
  2. Identify, quantify and characterize mineral-based secondary products/materials
  3. Raise awareness about what’s out there and about how these materials could be beneficially used
  4. Find and match these mineral-based materials end-uses to other resources
  5. Pursue value-added product development and technology opportunities

Unique Strengths, Expertise and Capabilities

  • This unique program makes the most out of what is mined, processed, and generated by mining and other mineral-based industrial activities. 
  • The NRRI team has over 30 years of experience in this area and understands the resources involved and the interdisciplinary connections.
