The Africa Zero Liquid Discharge (ZLD) System market is projected to grow from USD 33.9 million in 2025 to USD 58.5 million by 2035, at a CAGR of 5.6%. This steady growth is driven by increasing industrialization and stringent environmental regulations across the continent.
As industries such as mining, power generation, oil & gas, and chemicals expand, the demand for effective wastewater treatment solutions that minimize environmental impact intensifies. ZLD systems enable industries to recycle water and eliminate liquid waste discharge, addressing freshwater scarcity and pollution concerns in water-stressed African regions.
Rising government enforcement of water discharge norms and growing awareness about sustainable water management are significant factors propelling market adoption. Additionally, infrastructure investments in municipal wastewater treatment to combat urban water pollution add to market growth prospects.
Technological advancements are enhancing the efficiency and cost-effectiveness of ZLD systems in Africa. Hybrid ZLD technologies, combining membrane filtration with evaporation and crystallization, dominate the market due to their improved performance and energy savings. Innovations such as zero liquid discharge with integrated recovery of valuable by-products and digital monitoring for process optimization are gaining traction.
urthermore, the market benefits from increasing collaborations between technology providers and local governments or industries to deploy scalable and sustainable solutions tailored to regional water challenges. The growing need to comply with global sustainability goals and reduce water footprint across industrial sectors drives ongoing research and development, pushing the market toward higher adoption rates.
Government policies and regulatory frameworks play a critical role in shaping Africa’s ZLD market landscape. Environmental agencies across major African countries, including Egypt, South Africa, Nigeria, and Kenya, have introduced stricter effluent discharge standards to reduce water pollution.
These regulations encourage industries to invest in advanced ZLD technologies to meet compliance requirements. Furthermore, financial incentives, subsidies, and support programs for sustainable water treatment solutions enhance market accessibility. International funding and partnerships also contribute to infrastructure development.
As environmental sustainability and water conservation become national priorities, leading ZLD system manufacturers are investing in product innovation and local partnerships to capture growth opportunities while aligning with Africa’s evolving regulatory environment.
The Africa zero liquid discharge system market is segmented by system type into conventional and hybrid systems; by application into power generation, oil & gas, chemicals & petrochemicals, mining & metallurgy, pharmaceuticals, food, textile & leather, paper, and others (including water utilities, electronics, municipal wastewater treatment, agriculture, and heavy manufacturing); by aircraft into commercial, regional, business, military aircraft, and helicopter. By sub-region into Northern Africa, East & West Africa, and Southern Africa.
Hybrid segment is expected to grow at a CAGR of 6.2% from 2025 to 2035, outpacing the overall market CAGR of 5.6%.

The commercial aircraft segment emerges as the most lucrative based on demand and operational scale to grow at a CAGR of 6.3% from 2025 to 2035. This segment’s growth is underpinned by increasing air travel across the continent, driven by expanding urban centers and improved airport infrastructure.
This accelerated growth reflects the segment’s heightened need for stringent environmental compliance and advanced wastewater treatment systems within ground support and maintenance operations, where managing effluents from cleaning, de-icing, and manufacturing processes is critical. Regional and Business aircraft segments, benefiting from increased regional connectivity and private aviation demand, respectively.
However, their growth is comparatively moderate due to smaller fleet sizes and limited infrastructure development. Military aircraft and helicopter segments constrained by budget cycles and slower procurement rates to maintain stable demand for specialized ZLD applications related to defense and emergency services.
| Aircraft Segment | CAGR (2025 to 2035) |
|---|---|
| Commercial Aircraft | 6.3% |
Challenges
High Capital Outlay and Operating Cost
Zero Liquid Discharge (ZLD) technologies are not adopted by African nations to a large extent yet since primarily capital cost and operating cost are the issues. Technically efficient operation of waste water treatment plant, and maintenance cost, is earning an unacceptable amount of money for industries.
Lack of technocrat human resources as well as technology is also the issue for the widespread application of ZLD. Government subsidies, innovation that saves costs, and access to finances in an effort to facilitate support mechanisms must be improved so that the Zero Liquid Discharge technology can be implemented by local industries.
