Greening our energy and utilities

Industriepark Höchst recovers energy from waste and renewables

Infraserv Höchst's utilities strategy for Industriepark Höchst is sustainable and eco-friendly while remaining commercially sound for the long term.

Paragon in emission prevention and energy efficiency

Infraserv Höchst prevents over 500,000 metric tons of harmful CO2 emissions every year through internal power generation. Roughly two-thirds of these savings are achieved by the park's high-efficiency energy production facilities, which rely heavily on co-generation. The park's combined heat and power (CHP) plant, for example, achieves efficiencies of roughly 90 percent when combined with modern gas turbine plants – around double the efficiency of a conventional electric power station. In addition, waste heat from disposal and production plants is systematically recovered and fed into the park's supply networks, which significantly reduces fossil fuel consumption and CO2 emissions.

Waste-to-energy and renewable energy

Infraserv Höchst has stepped up its reliance on renewable energy and embraced a waste-to-energy strategy. Sources of renewable energy include high calorific value waste, also known as refuse-derived fuel, which is fired at the waste-to-energy plant. This not only makes environmental sense, but is required by law. Infraserv also converts organic waste such as expired food or digester waste into biogas at a biogas plant. The plant, one of the largest of its kind in Germany, can even produce biogas from industrial sewage sludge thanks to an innovative process. Food is not used – only food scraps or expired food. The resulting biogas is upgraded to pipeline-quality biomethane and fed into the public grid as sustainable energy produced at Industriepark Höchst.

Innovative projects driving sustainability at Industriepark Höchst

As a site operator, Infraserv Höchst aims to press ahead with sustainability projects at Industriepark Höchst and provide the park’s tenants with an infrastructure that also supports this move.

Gas turbines enable coal phase-out

Infraserv Höchst is investing a nine-figure sum to build two new gas turbines and modernize the current gas turbine plant at Industriepark Höchst. The site will be fully independent of coal once these projects are up and running.

Water conservation in water treatment

Water is an important resource for the chemical and pharmaceutical industry. Large quantities of water are needed at Industriepark Höchst as well. Around 95 percent of the water used at the park is river water extracted from the Main.
