Respect the Humanities

Tony Goldsby-Smith

The arts and humanities are essential to innovation, as we need a nation capable of seeing beyond the obvious and thinking creatively.

Adopting and scaling truly circular economies – where materials are kept in use for as long as possible to create greater sustainability – will really only occur through such an alignment.


With COVID-19 disrupting global supply chains and sparking questions about sovereign manufacturing capabilities, now is the time to adopt new technologies and practices that can help us to better manage our materials as resources, to reduce waste, and to create new supply chains and jobs.


This alignment of recycling and manufacturing is a key focus of my Sustainable Materials Research and Technology (SMaRT) Centre at the University of New South Wales in Sydney. We recently published two papers that explain the science and technology behind this concept.


The SMaRT Centre created the phrase "mircorecycling science" to describe its novel approach to researching innovative technologies and approaches related to reforming various waste streams into value-added materials and products. This process, which is achieved through decentralised manufacturing, is seen as a way to help regional and rural communities.


In the area of waste management, an ever-increasing population, technological advances, variable consumption trends and inefficiency in use of materials are forcing us to a near-crisis point. 


Australia’s governments have agreed to ban the export of glass, plastic, paper and rubber tyres from January 2021. We therefore need to start treating these waste items as the ‘renewable resources’ that they are, feeding them back into manufacturing and diverting them from landfill, stockpiling and incinerators.


A key challenge is that, at scale, existing, centralised recycling and waste treatment methods often simply turn things like PET bottles back into PET bottles. What we need is a recycling and manufacturing system that can innovate by reforming waste so that it can have more diverse and value-added end uses. 


Traditionally, recyclers have not seen themselves as manufacturers, and manufacturers have not seen themselves as recyclers – but we need them to.


If we accept that we need plastic, for instance, and that we want to keep it out of landfill and incinerators – which destroy the material forever – then we need a system that treats plastic as a renewable material.


One emerging development is the SMaRT Centre’s Microfactorie® technologies, which are modular-based and can reform waste into value-added materials for reuse and remanufacture. 


This decentralised model, which brings together recycling and manufacturing capabilities, is designed to transform problematic waste materials – such as glass, textiles and plastics – into new, value-added materials and products. Examples include green ceramics for use in the built environment, and filament for use by manufacturers as a feedstock and by other users who do 3D printing.


Many of these innovations have occurred as a result of funding from the Australian Research Council (ARC), which also enabled the formation of the ARC Green Manufacturing Hub, hosted by the SMaRT Centre. In 2020 a new ARC Microrecycling Hub hosted by UNSW will research battery and consumer wastes, and seek to progress the science and technology of microrecycling and bring about more innovations. I have had the privilege of being appointed Director for both of these ARC Hubs.


Through our ongoing collaborations with manufacturing and waste recycling industries, we have developed these manufacturing and recycling solutions to address some urgent waste and recycling problems while at the same time boosting manufacturing capabilities, job creation and environmental benefits.


We now have an incredible opportunity to solve for numerous existential problems at once: collectively, we can address waste and recycling issues, and reduce our carbon footprint, while also enhancing our manufacturing capability. This has the potential to create new supply chains and enhance our sovereign capability.


COVID-19 has unearthed the weaknesses in our existing plan for meeting certain sovereign challenges. There is the potential, though, to start a "green materials" movement whereby we use waste as a renewable resource in manufacturing as a way to supercharge our economies. As we move into a likely period of recession, this could help to lay the foundations for the next recovery or growth period.


The SMaRT Centre is exploring options for moving from producing the aforementioned green ceramics at a lab scale to producing them at an industrial scale. This effort, which includes plans for commercialisation, has the potential to set new benchmarks in innovation, efficiency and sustainability for the built environment sector.


The SMaRT Centre, using foundational, selective thermal transformation techniques developed as part of our microrecycling science, has also created an innovation that we call material microsurgery.


This new technique extracts from electronic waste valuable core elements that can be used in a novel way: as a hybrid layer to improve the performance of the surface of steel. This modification enhances regular steel by giving it a high-performing "super-surface".


We used the term "material microsurgery"for this technique because we were inspired by the processes that medical surgeons use in microsurgery, where they apply targeted and selective solutions to problems. 


We need our existing waste and recycling systems to adopt new processes and technology and to align themselves with manufacturing. That is, this is to be more of a lateral than a vertical integration or alignment.


In the face of our current waste, recycling and manufacturing challenges, doing onshore and more sophisticated processing of recycling as part of manufacturing can "change the game" for Australia, and for all countries around the world. 


The goal is to eliminate the word "waste" from our vernacular – because waste will become the renewable resource that we know it is.

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!
