While many organisations are scrambling to meet increasingly stringent sustainability legislation, there are specific companies who continue to exceed expectations by implementing advanced technologies and forward-thinking approaches to keep ahead of the curve.
One such sustainable undertaking is the rehabilitation of Rinaldo Road Quarry in Durban, an area which is now being developed with the assistance of Corobrik.
4 sustainable actions
Focused on rehabilitating quarries
Corobrik has always sought to rehabilitate its quarries with the policy of concurrent rehabilitation. In most cases there are two outcomes, with the area either being rehabilitated back to its original use or reused for other economic activities.
“Land from rehabilitated quarries is used for a variety of reasons,” explains Musa Shangase, Corobrik’s commercial director. “This includes office space, factories and warehousing – as can be seen at Briardene in Durban North – or retail space, as was done at Liberty Midlands Mall in the Pietermaritzburg region. In the Western Cape, one rehabilitated quarry is now a wine farm and upmarket housing estate.”
Technologies ensure savings
Alongside the quarry rehabilitation, Corobrik has invested in state-of-the-art green equipment, including extrusion technology at all its factories. This has allowed for enhanced product quality and dematerialisation that translates into significant energy reductions. Savings of 20% in drying and firing energy, reduced diesel use and an 8% reduction in mortar use are some of its sustainable achievements.
Further energy savings have been made following the implementation of advanced robotics at Corobrik’s Rietvlei, Lawley and East Brick factories. Through production flexibility, Corobrik can lower the demand on the energy grid during peak hours while also optimising the amount of energy needed for brick production.

Corobrik converted from a coal-fired to a natural gas-fired kiln at its Lawley factory, reducing emissions while also earning Corobrik the Certificates of Emissions Reductions by the United Nations Clean Development Mechanism – a first for any South African company.
How to achieve certification audits
Shangase notes that in July 2018, Corobrik’s KwaZulu-Natal and Gauteng factories undertook comprehensive certification audits. “All of them retained their ISO 14001 (Environmental Management Systems) and OHSAS (Occupational Health and Safety Management Systems) 18001 certification,” he explains. “We envisage that within the next couple of years, our factories in the Free State and Mpumalanga will also achieve these certifications.”
Continued research will benefit the consumer
The clay bricks rate highly with respect to their energy efficiency in terms of thermal properties and durability.
“We have adopted the Good Business Framework,” concludes Shangase. “This programme broadens the depth of understanding and commitment within the business from a sustainability perspective. We will continue to research and invest in lowering environmental impact in production while creating an energy-efficient product that benefits the consumer.”
