**Many industrial processes generate large amounts of heat that are not reused. This energy is often lost, while it could be directly reintegrated into operations.** Veolia develops **solutions** and **methods** to capture this excess heat and reuse it within industrial systems. [Learn more](#learnmore) ## **Recovering waste heat** to improve efficiency and reduce energy consumption **Recovered heat can be reused directly on-site for:** - **Preheating water or air** - **Supporting production processes** - **Covering additional thermal needs** This allows industries to [reuse energy](https://youtu.be/-wYV6uJTdic?si=gyJP7f1zwGP0UGPW) already available within their operations. ## **Identifying** Recoverable Heat Sources ![Codant-background](/sites/g/files/dvc3966/files/styles/crop_freeform/public/image/2026/03/Codant-background%20%281%29.png.webp?itok=fFdzJ74r) **These solutions are particularly relevant for key sectors such as iron and steel, metallurgy, cement, glass and chemicals, where heat is central to production processes such as data centers.** They can be integrated into existing installations, without major disruption to operations with the ultimate goal to reduce dependency on fossil fuels so that the region can optimize energy consumption. ![Energy - icon](/sites/g/files/dvc3966/files/image/2026/04/Energy%20-%20Icon.png) ## **Reuse** Within Operations ![Recovering industrial waste heat](/sites/g/files/dvc3966/files/styles/crop_freeform/public/image/2026/04/Waste%20Heat%20Recovery%20%26%20Valorisation.jpg.webp?itok=TekgSCN2) ## Learn more about **Waste Heat Recovery & Valorisation** [Talk to an expert](/contact-us) ![Codant-background](/sites/g/files/dvc3966/files/styles/crop_freeform/public/image/2026/03/Codant-background%20%281%29.png.webp?itok=fFdzJ74r) **Explore** **our relevant solutions** [Discover our Energy solutions](/energy-solutions) **\#** [Waste to Energy](/energy-solutions/waste-to-energy "Waste to Energy in South Africa") **\#** [Combined Heat and Power Solutions](/energy-solutions/heat-and-power-systems "Combined Heat and Power Solutions South Africa") **\#** [Solar PV systems](/energy-solutions/solar-pv-systems "Solar PV Systems in South Africa") **\#** [Waste Heat Recovery & Valorisation](/energy-solutions/waste-heat-recovery-services "Waste Heat Recovery & Valorisation South Africa") **\#** [Fuel Switch Solutions](/energy-solutions/fuel-switch-solutions "Fuel Switch Solutions in South Africa") **\#** [Anaerobic Digestion](/energy-solutions/anaerobic-solutions "Anaerobic Digestion in South Africa") **\#** [Energy Monitoring and Optimization](/energy-solutions/energy-monitoring-systems "Energy Monitoring and Optimization in South Africa")
