Sustainability Runner Up

Mpumatech has secured the runner-up position in the sustainability category of the 2024 Sassda & Columbus Stainless Awards, thanks to an innovative approach to addressing environmental challenges in the mining industry.

Andrew loannou of Mpumatech shares insights that saw the company earn recognition for a project born from an urgent need to implement more sustainable practices within the mining sector. “Our project was inspired by the environmental challenges posed by traditional mining methods, particularly the use of mild steel split sets, which are prone to corrosion and require frequent replacements, leading to significant environmental waste.”

Recognising the drawbacks of hot-dip galvanising, a process used to extend the life of mild steel but fraught with environmental concerns, Mpumatech sought a sustainable alternative. “We aimed to create a split set that not only matched the performance of mild steel but also eliminated the need for environmentally harmful coatings,” says Ioannou.

The solution is manufacturing split sets from 3CR12 stainless steel, which is inherently resistant to corrosion without additional treatments. This innovation significantly extends the service life of split sets in underground mining while reducing the environmental impact associated with material waste and the galvanising process. “By choosing 3CR12 stainless steel, we are supporting the industry’s operational needs and moving towards a more sustainable future in mining,” Ioannou adds.

Transitioning to 3CR12 stainless steel was not without challenges, particularly in changing the mindsets of end users who were accustomed to using galvanised mild steel. “Scepticism about moving away from traditional methods was a significant hurdle,” recalls Ioannou. Mpumatech addressed this challenge by collaborating closely with engineers, environmental specialists and procurement teams in field tests and comparisons to demonstrate the benefits of 3CR12 stainless steel, including its superior corrosion resistance and reduced environmental impact. “Through persistent education and open communication, we shifted perceptions and established 3CR12 as a sustainable, cost-effective solution,” Ioannou notes.

For Mpumatech, sustainability is more than just a trend; it’s a strategic business advantage. “By selecting materials like 3CR12, we reduce  maintenance and replacement costs, leading to long-term savings,” Ioannou explains. This focus on sustainability not only enhances business operations but also positions Mpumatech as a leader in promoting environmentally responsible practices in the mining industry.
