In 2024, Impala Rustenburg engaged an independent third-party expert to review its circular economy efforts. The assessment was informed by the operation’s specific context and knowledge of global circular economy practices, including South African mining peers.
The project was completed in August 2024, during which 32 of the operation’s circular economy initiatives were examined by the third party and found to be reasonably well aligned and using innovative approaches that go beyond ‘mining-as-usual.’
Impala Rustenburg’s engagement with local small businesses in delivering its circular economy impact was also highlighted. The study yielded several recommendations for the site, and the Group in general, including setting circular economy targets, the potential to collaborate on circular economy initiatives with value chain participants, and establishing a circular economy forum where ideas and initiatives can be shared with other Group operations.
Based on a total of 32 identified circular economy initiatives, 71% remain or are already operational. Four initiatives (12%) have been discontinued, including on-site equipment refurbishment and wood chip recovery. Two initiatives (6%) appear limited and have scope for significant expansion, including general waste recycling and recovering PGMs from catalysts. There are two pilot projects currently underway (soil building and re-using Li-ion batteries) and one initiative is at the planning stage (wood chip recovery).
Implats will continue to explore potential circular economy opportunities.
