Creating new revenue streams through
co-products in Africa

From the 2025 Annual Report

During the sugar manufacturing process, our businesses in Africa are increasingly producing a variety of co-products to create additional value.

In Tanzania, demand for potable alcohol (ethanol from molasses) is twice the local supply. A new distillery is being constructed to double Kilombero’s production for the domestic market, with an additional 14 million litres per year of high-quality ethanol forecast to be produced at the site. The expansion investment totals £48.2m and also includes a new fertilizer plant which will produce a potassium-rich, yield-enhancing fertiliser, suitable for sale to local cane growers.

Another intrinsic part of the sugar production process is power generation. Residual biomass from sugar cane is used to produce electrical energy, with surplus electricity made available for possible export into national grids.

In Eswatini, energy efficiencies resulting from investment in operations have enabled the export of approximately 55GWh of power annually to the national grid, creating a steady revenue stream.

In Tanzania, the new ‘K4’ plant is expected to provide up to 10MW of biomass power for export to the national grid. Opportunities to further increase electrical exports in Eswatini are also being examined, and to a lesser extent in South Africa.

As capacity is expanded in Africa and operational efficiencies further improved, we are upscaling our
co-product capabilities and diversifying our revenue streams, benefiting not only our business but local and national economies.
