An agreement struck by LanzaTech with New Zealand Steel reflects the biofuels company's move from development to commercialisation, says chief executive Jennifer Holmgren.
LanzaTech has its scientific base in Parnell and develops proprietary microbe technology which converts industrial waste gases into valuable chemicals including ethanol, used to make biofuel.
The company said the new agreement with NZ Steel would extend a pilot project to convert waste gases to low carbon fuels and chemicals.
The agreement gave NZ Steel and its Australian parent company Bluescope Steel the opportunity to use LanzaTech's technology commercially, it said.
The two companies had established a partnership in 2008 when LanzaTech built a pilot plant to produce ethanol from waste gases at NZ Steel's mill at Glenbrook.
