Specialty chemicals company LANXESS will be showcasing its extensive pigment palette for construction material coloring at the leading trade show bauma 2022 from October 24 to 30 in Munich.

The company will be sharing a platform with its sales partner Harold Scholz, which this year celebrates its 120-year anniversary. The focus will be on product solutions for sustainable building and application expertise in long-lasting concrete coloring.

“Sustainable construction is a vital part of the journey toward an economical and environmentally friendly future, which is why environmental product declarations are increasingly being used in the construction industry and are among the key prerequisites for structures to be granted sustainability certification,” says Michael Ertl, head of the Inorganic Pigments (IPG) business unit at LANXESS. “By delivering greater transparency for the basic materials of the construction industry, we are enabling our customers to make much more accurate assessments of the environmental impact of their products,” says Ertl.

The EPD (Environmental Product Declaration) helps to ensure the necessary transparency. It describes construction materials, products, and components in terms of their environmental impact in accordance with the international standard ISO 14025 and European standard EN 15804 for construction products and services of all kinds. As the first manufacturer of synthetic iron-oxide pigments, LANXESS offers audited environmental product declarations for selected product groups – verified in accordance with international standards by the Institut für Bauen und Umwelt e.V. (IBU), an association of building product manufacturers.

 “When raw materials used in production have verified EPDs, they can be factored into the life-cycle assessment of the construction material and have a positive influence,” says Holger Wendt, head of the Construction market segment at IPG. “Furthermore, EPDs offer a solid foundation for comparing iron oxide products from differing raw material suppliers,” he says.

Comparing different products is a worthwhile endeavor because the manufacturing process for synthetic iron oxide pigments uses a great deal of energy. LANXESS has therefore systematically invested in improving the carbon footprint of its pigments over the past few decades by implementing sustainable production processes at its production sites.
