CAPE TOWN, 30 June 2026: Cape Town Biogas (CTB) today announced that IIIM, through its Mid Market Infrastructure Fund 1, has acquired a minority shareholding in CTB. The investment was acquired from existing shareholder Metier Sustainable Capital Fund II, which remains the controlling investor.
Cape Town Biogas is an organic waste processing facility that utilises leading anaerobic digestion technology to process 250 tonnes of organic waste per day into three valuable outputs – Compressed Biomethane, Renewable Beverage-Grade Carbon Dioxide and valuable agricultural inputs. The facility plays a meaningful role in South Africa’s circular economy, providing a compliant and competitive organic waste disposal solution at scale, while producing valuable products for the commercial, industrial and agricultural sectors.
Robert Nel, Director and Principal at Metier, commented: “We are delighted to welcome IIIM as partners in this exciting project. The IIIM team brings deep local and sectoral expertise to CTB, and we look forward to building the Cape Peninsula’s preferred organic waste beneficiation facility together, creating value for our shareholders, the waste management sector, the environment, and the broader economy.”
Mark van Wyk, Chief Executive of IIIM, commented: “This transaction reflects our strategy of investing in local mid market infrastructure investments that deliver both financial returns and measurable social and economic impact. Our investment in Cape Town Biogas marks the Fund’s second entry into the biogas sector and represents our commitment to both energy security and innovative waste management. By diverting organic waste from landfills, we extend the lifespan of existing landfill sites, reserving capacity for materials with no alternative disposal route. The project strengthens energy resilience while creating meaningful employment opportunities across the value chain.”
Metier has led the redevelopment and strategic turnaround of CTB, establishing it as a vibrant producing asset. The collaboration between Metier, CTB and IIIM will unlock synergies, enhance capacity, and accelerate South Africa’s transition to a circular economy while delivering sustainable energy solutions and long term value creation.
