Auckland process technology company Avertana has won a leading global engineering award, taking out the Sustainability
category at the respected IChemE Global Awards, an annual worldwide competition for excellence in chemical engineering,
for its process that turns industrial waste from steelmaking into essential raw materials.
The IChemE Global Awards celebrate chemical and process engineering excellence. Now in their 25th year, they are widely
considered the world's most prestigious chemical engineering awards, Avertana has previously been a finalist in the
awards, in 2016 and 2017, in the SME category. This year, as a larger and more mature business, it entered the
Sustainability award. Former winners in this category include chemical industry leaders such as Johnson Matthey Davy
Technology, Petronas and BASF.
The awards are judged by a panel of senior figures in the chemical and process industries and Members of the Institution
of Chemical Engineers, with up to 30 judges scrutinising each years’ entries. Winners were announced at the IChemE
Global Awards Dinner on 7 November 2019 in Hull, UK.
Avertana has spent the past five years developing a world-first process that refines slag, a by-product of the steel
industry, into a suite of commodity raw materials used to make everyday products, with no residual waste. Avertana’s
technology not only consumes the solid by-products of steelmaking but also avoids mining and further waste generation by
conventional industrial processes.
CEO Sean Molloy said “This is an incredible result for our firm and its technology, especially considering the quality
of all the finalists in our category, and the calibre of former winners. I’m really proud of our team’s accomplishment
in achieving this level of international recognition.”
Working with slag from BlueScope New Zealand Steel, as well as samples obtained from steel mills in China, Russia, and
South Africa, Avertana has now confirmed that its process is applicable to more than 200 million tonnes of slag
globally, providing a global platform for technology deployment.
Using slag as the input to make raw materials for manufacturing has some surprising sustainability benefits. Avertana’s
process consumes 4-6 tonnes of slag to make a tonne of titanium pigment, which makes up around 80% of the revenue from a
factory using the technology. The balance is made into chemicals used in water treatment and fertilisers, as well as
inputs to make building materials such as cement and wallboard.
Compared with sourcing the same raw materials from conventional mining and chemical manufacturing processes, the
technology has a significantly smaller carbon footprint, while at the same time avoiding the mining and processing of
Avertana was also recently named a finalist in the inaugural Trans-Tasman Innovation Awards and has previously been
recognised by the Cleantech Group and ICIS Chemical Business as a leader in environmental innovation. For full results
