Starting today, the World Green Building Council is celebrating World Green Building Week. BASF also provides solutions that support sustainable building and contribute to climate protection. During the week, BASF will showcase a range of these solutions online under the hashtags #WGBW2017 and #OurHeroIsZero. These include insulation systems, solutions to optimize the concrete mix so that it can contain a higher proportion of recycled materials, ways to reduce impact sound, and more. Interested stakeholders can join the conversation from September 25 to October 1, 2017 by following BASF on  Facebook,  Twitter, or WeChat (@BASF_in_Action).
