PIGMENTURA by CHT wins German Sustainability Award in the Products category
25 December 2025: On 4th December 2025, the German Sustainability Award was presented in Düsseldorf in the Products category. The award has been presented since 2008 for exemplary sustainability achievements in business, local government, and research. With five competitions,800+ applicants and approximately 2,000 guests at the closing event, it is the largest award of its kind in Europe.
This year, the expert jury of the German Sustainability Award in the Products category honored those products that make particularly effective contributions to sustainable transformation in one of the five transformation fields (climate, resources, nature, society, and value chain). The focus was not only on technological innovations, but above all on the demonstrable impact of a product: To what extent did it contribute to conserving resources, reducing emissions, closing cycles, strengthening social responsibility or establishing sustainable consumption and production patterns? In addition, the jury considered aspects such as innovative strength, scalability, role model function, and long-term impact across the entire life cycle of a product. In a two-stage process, it identified those solutions that, beyond their actual function, have a positive impact on the economy and society.
The sustainable dyeing process PIGMENTURA from the CHT Group was honored in the Products category. CHT Group COO Dr. Lorenza Sartorelli accepted the sustainability award for PIGMENTURA in Düsseldorf from Gregor Steinbrenner, the host of the award ceremony on 4th December.
With PIGMENTURA, the CHT Group has developed a dyeing process that significantly improves resource efficiency in the textile value chain. The use of the pad-dry process achieves greater efficiency compared to conventional dyeing processes. At the same time, energy consumption, CO2 emissions, salt requirements, and the use of rinse water are reduced, and wastewater treatment is significantly reduced. This leads to savings in clean drinking water and makes an important contribution to the transformation of one of the most resource-intensive industries.
Eric Siekmann, Head of Sales Business Division Textile Solutions, on PIGMENTURA “Developing chemical products and processes that make textile manufacturing more sustainable is very important to us. Our development departments have always worked together with our colleagues in application technology and our customers to make energy- and water-intensive dyeing processes more sustainable.
PIGMENTURA is an example of how completely new processes can be developed by rethinking existing methods: The starting point was traditional pigment dyeing, in which the pigments have to be “bound” to the textile using special components. PIGMENTURA follows the idea of adsorbing pigments on the surface, thus simplifying the process.”
Dr. Annegret Vester, Chief Sustainability Officer at CHT, can confirm this “It was a highlight when it became clear how much potential for savings could be achieved in the dyeing process with PIGMENTURA. Classic reactive dyeing of textiles is associated with very high energy and water consumption. During the development phase, there were numerous obstacles to overcome, as each individual step in the process had to be developed to process maturity. Added to this is the diversity of textiles, which leads to significant changes in dyeing behavior, which we have now been able to standardize with PIGMENTURA.”
