Alex Fraser’s supply of sustainable alternative materials for Queensland’s construction industry is paving the way for greener roads. The company’s continued innovation has resulted in it claiming a state first certificate.
Recent modelling* undertaken by leading environmental solutions provider Veolia, has revealed that a drastic reduction in greenhouse gases is needed in Australia to prevent global warming.
Sydney has been ranked Australia’s most sustainable city in 2018, according to the Sustainable Cities Index from Arcadis.
The index ranks 100 cities on three pillars of sustainability which it defines as people, planet and profit.
- SUEZ provides $165,000 for sustainability projects
- Veolia releases Rethinking Sustainability case study videos
- Planet Ark and HP release sustainability report
Australian cities were mostly located in the centre of the list, with Sydney and Canberra reaching 34th and 35th place. Brisbane was listed as the 44th most sustainable while Melbourne trailed behind at 56.
All of the cities on the list performed well on people focused measures, scoring high in health, education and digital enablement. Cities performed moderately well when it came to profit due to employment and ease of doing business.
However, each Australian city scored worse in the planet pillar, with greenhouse gas emissions and waste management common issues across all four cities.
London was ranked the most sustainable city, with eight of the top ten spots being European cities.
The 2018 Sustainable Cities Index emphasised the impact of how digital technologies have impacted on citizen’s experience of the city, but it found that technology is not yet able to mitigate things like traffic jams, unaffordable transport options, the absence of green space or the uncertainties caused by ageing infrastructure.
Arcadis Australian Cities Director Stephen Taylor said with no Australian city cracking the top 30, there is a need to improve the long-term sustainability, resilience and performance of our cities.
“Across our cities, particularly in Sydney and Melbourne, we’ve seen a real shift over the last few years beyond green sustainability to social sustainability. Both government and private developments are increasingly focusing on how projects can better improve communities, including financial gains and community wellness,” Mr Taylor said.
“Despite the middle of the road rankings, the nation’s strong focus on developing integrated transit systems, addressing affordability and embracing sustainability in construction are all positive signs for future improvement across the three pillars,” he said.
Consumers are aware of the problems caused by packaging waste but expect the industry to provide more sustainable options, according to research launched by packaging company Pact Group.
The research has found 91 per cent of Australians are concerned about the impact of packaging, with 76 per cent more concerned about packaging waste now than they were five years ago.

- New national targets set within 2025 packaging plan
- Championing packaging sustainability
Despite this, the research has found that less than half would be willing to pay more for a product with environmentally friendly packaging.
Pact Group, Executive Chairman Raphael Geminder said that Australia’s packaging industry needs smarter packaging waste solutions, with consumer sentiment shifting and government action forthcoming.
“We can no longer simply rely on consumers to solve the problem, we need government and industry working side by side to create scaled, standardised solutions to tackle packaging waste,” Mr Geminder said.
“In order to realise this vision, we require industry-wide collaboration to simplify the recycling process for consumers.
“An integrated approach will allow us to deliver innovation at scale so new solutions do not simply increase cost and lose value. Consumers should not be forced to choose between value and sustainability,” he said.
The company has announced its own targets to meet those outlined by the Environment Minister Melissa Price last week. Pact Group aims to eliminate all non-recyclable packing, offer 30 per cent recycled material across its portfolio and provide solutions to reduce, reuse and recycle all single use secondary packaging in supermarkets by 2025.
Mr Geminder said there are tangible, incremental changes that can be made today, with longer-term changes which will require cross industry collaboration.
“I will be calling on my industry colleagues to work together with us on common platforms, agreed standards and processes that will create a framework for manufacturers, brand owners and retailers to solve problems systematically,” he said.

Around 100 tonnes of recycled glass and plastic have been used in a road resurfacing project in Melbourne’s City of Yarra.
A road resurfacing trial took place in the suburb of Richmond, with Stanley and Margaret Street repaved with an asphalt product containing recycled glass, asphalt and high-density polyethylene (HDPE) plastic.

The project repurposed around 7300 two litres plastic bottles and 55,000 glass bottles, which is equivalent to the annual kerbside recycling collection for every household on Stanley Street.
The City of Yarra engaged recycling company Alex Fraser for the project and has called on the company to repair and repave more streets in the coming weeks, which will use an additional 1000 tonnes of sustainable asphalt.
Alex Fraser Managing Director Peter Murphy said this was a prime example of how a circular economy can be achieved – with government, industry and community working together to recycle problem waste streams, and invest in recycled materials to build new, sustainable infrastructure.
“The City of Yarra’s progressive approach to the use of sustainable material is an excellent illustration of how local councils can proactively reuse the waste generated in their communities to build and maintain their cities while reducing the carbon footprint of their projects by up to 65 per cent,” Mr Murphy said.
City of Yarra Mayor Daniel Nguyen said the City of Yarra had worked with Alex Fraser to incorporate sustainable materials like glass and recycled concrete into its road works.
“As a council with a strong focus on sustainability we are excited about using recycled plastics in our latest roadworks for the wide range of environmental benefits it delivers,” said Cr Nguyen.
More than 100,000 pieces of contact lens waste have been diverted from landfill in Australia as the Bausch + Lomb Recycling Programme hits its one-year anniversary.
Bausch + Lomb launched its recycling programme in partnership with TerraCycle in 2017 to help Australians keep contact lenses, lens cases and blister packs out of landfill.

Any contact lens waste can be shipped to TerraCycle for no charge, who will shred, wash and melt it down into sustainable raw material to use in manufacturing instead of virgin plastic.
A number of public drop-off locations are also available around Australia in environmentally conscious optometry stores.
For each kilogram collected and sent to TerraCycle, Bausch + Lomb donates $1 to the Optometry Giving Sight foundation.
Optometrist at Bailey Nelson Claremont in Perth Jayson Chong said collecting locals’ contact lens waste helps his team champion sustainability.
“While most of our customers are educated about the environment, many are surprised to learn that we can also recycle contact lenses!” Mr Chong said.
“Running an eco-friendly business helps us build a good reputation and promote workplace satisfaction for our staff.”
Optometrist at Point Cook & Sanctuary Lakes Eyecare in Point Cook in Victoria Jenkin Yau said joining the program was an important way for his store to contribute to the community.
“We felt it was important to become a public drop-off location for the program as our customers like to do the right think socially and environmentally,” Mr Yau said.
“Additionally, the generous donations from Bausch + Lomb to Optometry Giving Sight made the decision very easy.”
TerraCycle Australia & New Zealand General Manager Jean Bailliard said they are thrilled to celebrate this milestone, as it is a huge win for the environment.
“We’re really driven by the commitment of companies like Bausch + Lomb who are dedicated to tackling waste.”
Coffee grounds could be used to create biodegradable plastic coffee cups thanks to new research from Macquarie University.
The process converts the spent coffee grounds into a lactic acid which is then turned into a plastic, however the method is still being refined by researcher Dominik Kopp.

- Planet Ark partner with Bingo Industries to divert coffee grounds
- BioPak and Perth cafes combine to compost coffee cups
Because 50 per cent of coffee grounds are made up of sugars, they can be converted into bio-based chemicals.
The method was inspired by a metabolic pathway that is thought to exist in an evolutionary ancient organism, which lived in hot and extremely acidic environments.
“Australians consume six billion cups of coffee every year, and the coffee grounds used to make these coffees are used only once and then discarded,” says Mr Kopp.
“In Sydney alone, over 920 cafes and coffee shops produced nearly 3,000 tonnes of waste coffee grounds every year.
“Ninety-three per cent of this waste ends up in landfill, where it produces greenhouse gases that contribute to global warming.”
Mr Kopp sources the coffee grounds from one of the shops on Macquarie’s campus and took them back to the lab.
“We assembled a synthetic pathway to convert the most abundant sugar in the coffee grounds, mannose, into lactic acid,” he says.
“Lactic acid can be used in the production of biodegradable plastics, offering a more sustainable and environmentally-friendly alternative to fossil fuel-derived plastics.
“You could use such plastics to make anything from plastic coffee cups to yoghurt containers to compost bags to sutures in medicine.”
His next step will be to further refine the conversion pathway and improve the yield of lactic acid.
“I think my project is one of many interesting approaches on how to use synthetic biology in a responsible manner for the development of a more sustainable and greener industry that doesn’t rely on crude oil,” says Dominik.
“The simple idea that we are converting waste into a valuable and sustainable product is extremely exciting!”
