One of our most exciting sustainability projects in 2017 came from our Environmental team in Krugersdorp, South Africa. The question: How to turn an underutilized process by-product into a novel construction material and – at the same time – harness an opportunity to assist the underserved population around the site?
The Krugersdorp site had built up significant stocks of an aggregate By-product. Onsite storage was approaching saturation, and no one wanted to landfill the product. Instead, the team identified an existing South African technology solution that creates hollow core building blocks using similar aggregates. The blocks were sculptured to enable ease of use even for novice builders, allowing the construction of basic buildings and homes – quickly and safely.
Going forward, the site intends to increase production and develop relationships with more members of the local community so that the blocks can be utilized in sustainable construction projects for community housing – all built by members of the same local communities.
