Partnership with DST-CHEMICALS
HOCHBAHN has partnered with DST-CHEMICALS to enhance sustainability in vehicle maintenance and cleaning. In the Barmbek subway workshop, the use of DST-DEGREEZ/9E, a biodegradable and water-based cleaner, has been implemented to improve the degreasing process of vehicle components.

Energy and Water Savings
The introduction of DST-DEGREEZ/9E allows the cleaning plant's temperature to be reduced from 60°C to 45°C, achieving energy savings of up to 45%. Additionally, water consumption has been significantly reduced, contributing to lower environmental impact and waste.
