Zu sehen ist ein aufgeschnittener oder geöffneter Wandaufbau an einer Gebäudeecke. In der Mitte befindet sich ein weißes, körnig strukturiertes Dämmmaterial, das senkrecht zwischen zwei Wandflächen liegt. Rechts davon ist ein Armierungsgewebe aus feinem, weißem Kunststoffgeflecht sichtbar, das teilweise von Putz umgeben ist.

HBCD

HBCD or HBCDD stands for hexabromocyclododecane and is a ring-shaped, brominated hydrocarbon molecule. Due to its technical properties, HBCD was primarily used as a flame retardant for plastics and was therefore mainly used in Building insulation materials made of polystyrene (EPS / XPS)partly also in packaging plastics (EPS) for use. In May 2013, HBCD was categorised as a persistent pollutant (POP) under the international Stockholm Convention. This resulted in a worldwide ban on trade and use (with transitional periods). Since 22 March 2016, products (substances, mixtures and articles) containing more than 100 mg/kg HBCD may no longer be manufactured and sold in the EU. A temporary exemption for polystyrene (EPS) ended on 21 February 2018. Insulation materials containing HBCD are not classified as "hazardous waste" in Germany, but there is a separate collection requirement, a mixing ban and obligations to provide evidence and keep records.
