Life cycle assessment for additives
BYK Additives & Instruments is the first additives producer to carry out a life cycle assessment (LCA) for individual products and have it certified by TÜV Rheinland. The internationally recognized standards ISO 14040 and 14044 provide the basis for the LCA. Now, certified statements on environmental impact factors, including the carbon footprint, can be made for up to four products in total.
“This certification enables us to set new standards for our sector,” Dr. Roland Peter, President Division BYK Additives & Instruments, explained at the presentation of the certificates in Wesel. “The product-related life cycle assessments represent a further milestone in our Greenability strategy. In this way we are helping our customers worldwide to manufacture eco-friendly products.” In the long term, according to Dr. Peter, life cycle assessment is likely for a series of further defoamers or wetting and dispersing agents. Currently, four more additives are being analyzed.
Dispesion agents and defoamers
TÜV Rheinland is an internationally acknowledged and accredited testing institute. The company initially certified DISPERBYK®-190, a dispersion agent for aqueous systems, along with three defoamers: BYK®-012, BYK®-023, and BYK®-1740. These are used, for example, in architectural coatings or paper coatings. The defoamers are food-compatible and are characterized by their exceptionally low VOC content. BYK®-1740 is also biodegradable, since it is produced from renewable materials.
Data on the manufacturing process as well as on the upstream processes are required as the basis for the LCA. In addition, such factors as energy consumption, transport routes, and the raw materials used are taken into consideration. The findings obtained are documented in the form of an Environmental Product Declaration (EPD) in accordance with the international standard ISO 14025.
