Harmful carbon dioxide emissions to be converted to useful chemical building blocks
Engineers from the University of New South Wales (UNSW) have found a novel way to transform harmful waste carbon dioxide into chemical building blocks which can be used to make useful industrial products.
If utilised on a large international scale, the newly developed process could quicken the global transition to a cleaner, greener economy.
Carbon dioxide emissions are the primary greenhouse gas emitted through day-to-day human activities. Whilst it is a naturally occurring greenhouse gas, human industrial activity has resulted in an unsustainable increase of carbon dioxide in the atmosphere, trapping heat and driving future widespread, catastrophic climate change.
Whilst the ability to convert carbon dioxide into useful material is not new, the process has historically been a costly and complicated one.
According to Dr Daiyan, a research lead on the project, “past attempts have used expensive materials such as palladium, but this is the first instance where a very cheap and abundant material, made locally in Australia, has been successfully applied to the problem of waste carbon dioxide conversion”.
In collaboration with Dr Emma Lovell, Dr Daiyun has now developed a method that they say is as simple as playing with Lego.
Research duo Dr Rahman Daiyan and Dr Emma Lovell from UNSW’s School of Chemical Engineering claim that by making zinc oxide at very high temperatures using a technique called flame spray pyrolysis (FSP), they can create nanoparticles which act as the catalyst for turning carbon dioxide into ‘syngas’ - a mix of hydrogen and carbon monoxide used in the manufacture of industrial products.
Dr Lovell describes ‘syngas’ as the chemical equivalent to Lego.
“This is because the two building blocks - hydrogen and carbon monoxide - can be used in different ratios to make things like synthetic diesel, methanol, alcohol or plastics, which are very important industrial precursors,” said Dr Lovell.
“So essentially what we are doing is converting carbon dioxide into these precursors that can be used to make all these vital industrial chemicals”.
Both Dr Lovell and Dr Daiyan said that their work is effectively closing the loop in the industrial process that creates harmful greenhouse gases. They hope to soon determine the eventual mix of the ‘syngas’ building blocks produced by the carbon dioxide conversion.
According to Dr Daiyan, “at the moment you generate ‘syngas’ by using natural gas - so from fossil fuels. But we are using waste carbon dioxide and then converting it to syngas in a ratio depending on which industry you want to use it in.”
The duo’s next project will scale up their efforts to transform waste gas into useful materials to the point where it would have the potential to convert the entirety of the carbon dioxide waste emitted by a power plant.

As Australia grapples with a critical skills shortage, many are now encouraging young people to embrace a career in the trades, where a wealth of opportunities awaits.
In 2016 I published a blog article titled Moonshots for Australia: 7 For Now. It’s one of many I have posted on business and innovation in Australia. In that book, I highlighted a number of Industries of the Future among a number of proposed Moonshots. I self-published a book, Innovation in Australia – Creating prosperity for future generations, in 2019, with a follow-up COVID edition in 2020. There is no doubt COVID is causing massive disruption. Prior to COVID, there was little conversation about National Sovereignty or supply chains. Even now, these topics are fading, and we remain preoccupied with productivity and jobs! My motivation for this writing has been the absence of a coherent narrative for Australia’s business future. Over the past six years, little has changed. The Australian ‘psyche’ regarding our political and business systems is programmed to avoid taking a long-term perspective. The short-term nature of Government (3 to 4-year terms), the short-term horizon of the business system (driven by shareholder value), the media culture (infotainment and ‘gotcha’ games), the general Australian population’s cynical perspective and a preoccupation with a lifestyle all create a malaise of strategic thinking and conversation. Ultimately, it leads to a leadership vacuum at all levels. In recent years we have seen the leadership of some of our significant institutions failing to live up to the most basic standards, with Royal Commissions, Inquiries and investigations consuming excessive time and resources. · Catholic Church and other religious bodies · Trade Unions · Banks (and businesses generally, take casinos, for example) · the Australian Defence Force · the Australian cricket teams · our elected representatives and the staff of Parliament House As they say, “A fish rots from the head!” At best, the leadership behaviour in those institutions could be described as unethical and, at worst….just bankrupt! In the last decade, politicians have led us through a game of “leadership by musical chairs” – although, for now, it has stabilised. However, there is still an absence of a coherent narrative about business and wealth creation. It is a challenge. One attempt to provide such a narrative has been the Intergenerational Reports produced by our federal Government every few years since 2002. The shortcomings of the latest Intergenerational Report Each Intergenerational Report examines the long-term sustainability of current government policies and how demographic, technological, and other structural trends may affect the economy and the budget over the next 40 years. The fifth and most recent Intergenerational Report released in 2021 (preceded by Reports in 2002, 2007, 2010 and 2015) provides a narrative about Australia’s future – in essence, it is an extension of the status quo. The Report also highlights three key insights: 1. First, our population is growing slower and ageing faster than expected. 2. The Australian economy will continue to grow, but slower than previously thought. 3. While Australia’s debt is sustainable and low by international standards, the ageing of our population will pressure revenue and expenditure. However, its release came and went with a whimper. The recent Summit on (what was it, Jobs and Skills and productivity?) also seems to have made the difference of a ‘snowflake’ in hell in terms of identifying our long-term challenges and growth industries. Let’s look back to see how we got here and what we can learn. Australia over the last 40 years During Australia’s last period of significant economic reform (the late 1980s and early 1990s), there was a positive attempt at building an inclusive national narrative between Government and business. Multiple documents were published, including: · Australia Reconstructed (1987) – ACTU · Enterprise Bargaining a Better Way of Working (1989) – Business Council of Australia · Innovation in Australia (1991) – Boston Consulting Group · Australia 2010: Creating the Future Australia (1993) – Business Council of Australia · and others. There were workshops, consultations with industry leaders, and conferences across industries to pursue a national microeconomic reform agenda. Remember these concepts? · global competitiveness · benchmarking · best practice · award restructuring and enterprising bargaining · training, management education and multiskilling. This agenda was at the heart of the business conversation. During that time, the Government encouraged high levels of engagement with stakeholders. As a result, I worked with a small group of training professionals to contribute to the debate. Our contribution included events and publications over several years, including What Dawkins, Kelty and Howard All Agree On – Human Resources Strategies for Our Nation (published by the Australian Institute of Training and Development). Unfortunately, these long-term strategic discussions are nowhere near as prevalent among Government and industry today. The 1980s and 1990s were a time of radical change in Australia. It included: · floating the $A · deregulation · award restructuring · lowering/abolishing tariffs · Corporatisation and Commercialisation Ross Garnaut posits that the reforms enabled Australia to lead the developed world in productivity growth – given that it had spent most of the 20th century at the bottom of the developed country league table. However, in his work, The Great Reset, Garnaut says that over the next 20 years, our growth was attributable to the China mining boom, and from there, we settled into “The DOG days” – Australia moved to the back of a slow-moving pack! One unintended consequence of opening our economy to the world is the emasculation of the Australian manufacturing base. The manic pursuit of increased efficiency, lower costs, and shareholder value meant much of the labour-intensive work was outsourced. Manufacturing is now less than 6% of our GDP , less than half of what it was 30 years ago!
