Green Aggregates for Sustainable Construction

Slaggregates® supplies green aggregates to the construction sector, a division of BAG™ Bafenyi African Group (Pty) Limited. We pride ourselves with the ability to unlock the underlying value of slag from historical stockpiles in millions of tonnes through cutting-edge processing, sequestration and logistics in line with industry standards.

About Us

Slaggregates® is a proprietary of Bafenyi African Group (Pty) Limited, encapsulated by the need to offer superior quality Green Construction Materials and achieve Sustainable Structural Integrity in Modern Engineering.

We are the equilibrium of Sustainable Infrastructure Development and Permanent Mineral Sequestration. Slag, a stony waste matter separated from metals during smelting or refining of ore is gradually becoming a recognised alternative to aggregates quarried from virgin land.

We secure long-term Slag-Use-Agreements with Mineral Processing Plants such as Smelters in South Africa and the entire African continent. Our value proposition to the Mineral Processing Plants is to relieve them of the environmental burden on their slag residuals, an industrial symbiotic intervention.

Our current operations are in the North West province, moving thousands of tonnes per month where we have secured a long-term agreement on Samancor’s historical stockpiles. We are also gaining traction in securing other historical and current stockpiles where it is feasible.
