Overview

Green Brine Technologies is a Namibian company developing the country’s first integrated desalination-brine-to-chlor-alkali facility in the Erongo Region.

The project converts high-salinity reject brine from existing desalination plants into essential industrial chemicals — primarily caustic soda, hydrochloric acid, chlorine and sodium hypochlorite — while recovering minerals and reducing environmental discharge into the ocean.

Namibia currently imports 100% of its chlor-alkali chemicals, mainly for the mining, water treatment and industrial sectors. Green Brine addresses this by creating local production capacity using a circular-economy approach that turns a waste stream into valuable products.

The project is currently at the advanced pre-feasibility / early FEED stage, with a projected CAPEX of approximately USD 63.6 million and a planned capacity of 50.8 tonnes per day of caustic soda.

Why Investing

Brine-to-Chemicals Circular Model

Green Brine uses existing desalination brine as its primary feedstock for chlor-alkali production, reducing reliance on mined salt and freshwater while creating value from an industrial by-product.

Strategic Location & Import Substitution

Its proximity to major desalination plants, mining operations and industrial offtakers positions the project to supply essential industrial chemicals locally, addressing regional dependence on imports.

Integrated Environmental & Industrial Opportunity

Combines reduced brine discharge with local industrial development, with potential to incorporate renewable energy and green hydrogen into the production process.
