Paragraph starter

The effective integration of mining waste into a circular economy necessitates a robust classification system. As highlighted by Lemière and Lord (2026), existing classification schemes often fall short in comprehensively assessing suitability for reuse due to factors like chemical stability. Therefore, any design project aiming to utilize such materials must undertake a thorough, multi-faceted characterization process to ensure both functional performance and environmental safety.
