New Zealand Steel has signed a future supply agreement with Marlborough cleantech company Carbonscape, and is exploring other options for making use of Carbonscape's patented microwave technology.
Carbonscape has developed a microwave process for converting forestry waste into high value carbon products, including metallurgical coke, which can be used as a fuel and in the steel making process.
A trial shipment is planned for 2014, when New Zealand Steel will use Carbonscape's 'green coke' as an additive in its steel making operation at Glenbrook to reduce carbon emissions.
Following successful trials, a scaled up production plant is being built to deliver commission samples.
Carbonscape is currently securing investment to enable expansion to commercial production.
