thyssenkrupp Steel supplies CO₂-reduced bluemint^® Steel for water pipeline project in Angola

Duisburg, April 10, 2026. thyssenkrupp Steel is supplying approximately 1,000 tons of CO₂-reduced bluemint^® Steel for a major water pipeline project in Angola, located in southwestern Africa. The material will be used as part of the Quilonga Grande development project, which is intended to fundamentally improve the water supply for the capital city of Luanda in the future.

Hot-rolled strip from Duisburg – processed into large-diameter pipes in Salzgitter

The bluemint^® Steel hot-rolled strip produced by thyssenkrupp Steel is processed into spiral-welded pipes at Mannesmann Grossrohr in Salzgitter. The pipes reach lengths of 13.5 meters and – depending on the route section – diameters ranging from 508 millimeters to 1,626 millimeters. In this project, bluemint^® Steel is used in particular for pipes with a diameter of 1,220 millimeters and a wall thickness of around 12 millimeters. In total, the new water system comprises approximately 105 kilometers of pipeline.

Pipeline project is a key component of Angola’s water supply

The new water transport system will play a central role in supplying die city of Luanda. The metropolis, with a population of around ten million, has faced a massive drinking water deficit of approximately 1.2 million cubic meters per day for years. In many districts, water has so far been supplied primarily by tanker trucks. The new water pipeline is a key component for a reliable and sustainable water supply for the population.

Georgios Giovanakis, Chief Sales Officer at thyssenkrupp Steel: “We are pleased that our bluemint^® Steel is being used in this important infrastructure project. In doing so, we are taking on responsibility within the framework of long-term partnerships, as access to clean drinking water is a fundamental prerequisite for quality of life and social development. Especially in a country that already relies heavily on renewable energy and has a comparatively low per capita CO₂ footprint, bluemint^® Steel makes a meaningful contribution to further sustainable development.”

The Quilonga Grande project demonstrates how low-carbon materials can be specifically integrated into international infrastructure projects. Through the use of bluemint^® Steel, thyssenkrupp Steel is making an important technological contribution to making supply infrastructures more resilient and climate-friendly.

bluemint^® recycled: CO₂-reduced steel through increased scrap content

bluemint^® recycled is a CO₂-reduced steel from thyssenkrupp Steel in which a specially processed scrap product is used in the blast furnace process. By using recycled material, primary raw materials can be conserved and process‑related CO₂ emissions significantly reduced – without compromising the usual mechanical or processing properties.
