Founded in 2016, activated carbons producer Rotocarb was established with the goal of servicing the carbon-based water purification needs of South Africa. Today, Rotocarb stands as an innovative and pioneering enterprise, dedicated to producing sustainable and locally made activated carbons to meet not only South Africa’s, but the world’s purification needs. Utilising macadamia nut shells, a by-product of the nut industry, this biomass is transformed into high-grade activated carbons through a clean, eco-friendly and energy efficient thermal manufacturing process.

Rotocarb’s novel technology, which is operated under an exclusive license in conjunction with its strategic partners, has created an agile, robust and competitive business that is able to offer premium grade activated carbons without the burden of minimum order quantities, long lead times and duties suffered by imported alternatives. 

Rotocarb’s operations span across three provinces which collectively see to the production of over 1 500 t/y of activated carbon across 20 product ranges. Rotocarb’s facilities harness solar power, harvest rainwater and employ innovative autogenous thermal processes in the manufacturing of its products. Rotocarb’s efforts towards global sustainability are particularly aligned with the United Nations Sustainability Development Goals (SDGs) for SDG 6 - Clean Water and Sanitation, SDG 7 - Affordable and Clean Energy and SDG 13 – Climate Action. 

Rotocarb is South Africa’s largest activated carbon manufacturer and is committed to growing the business locally and regionally while contributing to a sustainable future with its novel and high-quality activated carbon products. 


To provide world class activated carbon products to the filtration, purification and food processing industries while contributing to the socio-economic development of South Africa in an environment friendly and sustainable manner.
