In a strategic venture with the Industrial Development Corporation (IDC), Nafasi Water Technologies has commissioned the first module of its purpose-designed waste sludge processing facility at the Highveld Industrial Park, in eMalahleni, Mpumalanga.

The facility is engineered to recover and beneficiate waste sludge generated from mine- impacted-water treatment processes and convert these by-products into commercially saleable chemical inputs for fertiliser production.

It represents a significant step in commercialising a locally developed industrial solution that turns an environmental liability into a productive manufacturing opportunity.

“The innovation lies not only in treating water, but in extracting further economic value from the residual waste stream, thereby reducing landfill disposal, lowering the long-term cost of treatment and creating a new domestic source of industrial chemicals,” says Nafasi Water Technologies CEO Suzie Nkambule.

The facility is located in a province that is at the intersection of heavy industrial activity, coal-transition pressures, mine-water risk and significant agricultural demand.

“The Mpumalanga region needs investment in alternative industries that respond to the challenges of the energy transition and the long-term effects of coal mining on water resources.”

She explains that the engineering innovation at the heart of Nafasi Water Technologies approaches this holistically by strengthening catchment resilience while building a new industrial venture.

As both funder and equity partner, the IDC is supporting the scale-up of a circular- economy platform that links mining, water treatment, chemical manufacturing and agriculture in a single value chain.

The IDC’s investment underscores its mandate to back high-impact, innovation- driven ventures that build new industrial capability, support localisation and unlock commercially viable responses to South Africa’s water-security and environmental challenges.

Its development finance approach enabled the incubation and deployment of these technologies in markets where early-stage industrial innovation carries significant technical and commercial risk.

“This is precisely the kind of investment the IDC is mandated to support – a locally developed technology platform with the potential to build new manufacturing capacity, localise imported inputs, strengthen water resilience and create a scalable model for industrial renewal in mining regions,” says IDC industry planning and development divisional executive Rian Coetzee.

“Our role as funder and equity partner is to help derisk innovation that can unlock new productive sectors and deliver measurable developmental impact.”

By combining project development support, equity participation and long-term industrial partnership, the IDC is helping to move the venture beyond demonstration into a platform that can be replicated across other mining regions where mine-water treatment, waste reduction and local chemical production are strategic priorities.

The commissioning of the new facility reflects vision, determination and technical excellence.

It also reflects something that South Africa really needs more of: courage to look at difficult problems differently and create new solutions, he says, noting that it serves as a replicable blueprint for how development finance can help convert early-stage industrial technologies into bankable, revenue-generating assets.

“[The plant is] more than a facility; it is a bridge from pilot to commercialisation, a bridge from environmental challenge to industrial value. It is a bridge from imported pensions to local production, and a bridge from today's regional economy to tomorrow's industrial opportunity,” he adds.

“We want to see a modular expansion of this. We want to see similar plants elsewhere in the country that also address this initiative.”

Nafasi Water already operates mine-water reclamation facilities in the region, positioning the Highveld Industrial Park facility close to its primary feedstock sources.

Over time, Nafasi aims to maximise the value extracted from waste by-products through further technology development, including the potential deployment of ion- exchange processes to recover useful chemicals directly from mine-impacted water.

This creates a pathway for continuous innovation, further industrial investment and the development of a South African circular water-technology capability with relevance beyond Mpumalanga.
