Neustark

Concrete causes 7% of global CO2 emissions – more than 2 x more than global aviation.  Concrete producers (e.g. Holcim, Heidelberg, CEMEX) want to achieve zero emissions by 2050. Neustark enables zero emissions concrete by capturing concrete production emissions from the atmosphere and permanently converting them to limestone. This climate positive limestone replaces cement and sand which are major cost drivers for concrete production.
