Eco-friendly innovations and solutions for industry

About five million cubic meters of water are treated every day using membrane technology from Siemens. This quantity is equivalent to the daily water consumption of a megacity such as Mexico City.

Electrostatic precipitators are used to clean exhaust gases from industrial and waste incineration plants as well as in power plants. They remove rust and dust particles from exhaust gases and currently operate at a filtration efficiency of nearly 100%. They use ions to induce an electrical charge in the dust particles. These charged particles are then collected on an anode and remove mechanically. At a coal-fired power station, this amounts to up to ten tonnes of dust per day that is not emitted into the environment.

The COREX smelting-reduction process is the eco-friendly alternative to conventional pig iron manufacturing. The use of natural resources and energy is reduced, as are operating costs, and teliable compliance with existing regulations and environmental requirements is ensured.

The extraction of electricity and heat from hot water in the Earth’s crust produces no CO2 or any other greenhouse gases. Since the plant runs in base-load mode and can be operated with few overheads, operating costs are low and an investment is made in a form of energy that is independent of business cycles.

Thanks to Siemens expertise, steam for generating electrical power is obtained from industrial waste heat in energy-intensive sectors such as the cement, glass and metal industry. This additional electricity generation reduces energy costs without burning fuel, so no additional CO2 is released into the atmosphere. The energy efficiency of the plant is increased and the overall environmental impact of the industrial production process is reduced.

With the SISHIP WHR system, Siemens offers clean, economical power generation from the exhaust gas of diesel-powered ships. The extra energy captured means a reduction in emissions of CO2 and NOX, for example, while at the same time less fuel is needed.
