First SA road built with plastic bags and glass

The first South Australian road built with soft plastics and glass at Happy Valley in the City of Onkaparinga will utilise plastic from approximately 139,000 plastic bags and packaging and 39,750 glass bottle equivalents.

Downer and City of Onkaparinga have partnered with resource recovery and recycling companies Close the Loop and RED Group for the project, following similar projects in NSW and Victoria.

Along with soft plastics and glass, toner from about 3200 used printer cartridges and more than 50 tonnes of recycled asphalt were also repurposed to create 265 tonnes of asphalt used to construct the road along Caribbean Crescent in Happy Valley.

Downer Executive General Manager Road Services Dante Cremasco said the milestone event demonstrated the importance of partnerships with other thought leaders to create economic, social and environmental value for products that would more than likely end up in landfill, stockpiled, or as a pollutant in natural environments.

“Together with City of Onkaparinga and our partners, we have proven that with thought leadership and the tenacity to make a positive difference, we have set a new benchmark in the state when it comes to sustainability by creating new avenues to recycle and repurpose waste materials into new streams of use. It’s all about pulling products, not pushing waste,” Mr Cremasco said.

“Further to the direct sustainability benefits, this cost competitive road product called Reconophalt has enhanced properties of improved strength and resistance to deformation making the road last longer, andallowing it to better handle heavy vehicle traffic,” Mr Cremasco added.

City of Onkaparinga Mayor Erin Thompson said this is an exciting South Australian first and demonstrates council’s commitment to working with industry on innovative and cost-effective solutions to a changing operating environment.

“The City of Onkaparinga manages and maintains over 1350 kilometres of sealed roads and works hard to ensure they’re well maintained as cost effectively as possible and in line with leading asset management principles,” Mayor Thompson said.

“We also collect approximately 14,000 tonnes of recyclables every year. Major disruptions in international markets for recyclables over the last 12 months present significant challenges, as well as emerging opportunities.”

“Creating local demand for recyclables products is one such opportunity and this is a fantastic example of what can be achieved by government working with industry.”

Downer partnered closely with Close the Loop to tailor waste products such as soft plastics to suit a road construction application.

“Our close partnership with Downer, along with our collaborative partnership with RED Group has allowed us to design, develop and manufacture sustainable products using problematic waste streams. We are very pleased to see soft plastics used for the first time in a SA road,” said Nerida Mortlock, General Manager of Close the Loop Australia.

Nestlé pledges to improve recycled content in EU packaging

Nestlé has pledged to increase the amount of recycled plastics the company uses in some of its packaging in the European Union by 2025.

The company aims to include 25 to 50 per cent recycled materials in PET layer in laminates, caps on glass jars and tines, trays for meat products and shrink films for display trays.

It follows Nestlé’s pledge in April to make all of its packaging recyclable or re-useable by 2025.

The announcement is part of the voluntary pledging exercise on recycled content by the European Commission. Nestlé CEO for Zone Europe, Middle East and North Africa Marco Settembri delivered the pledge in person to the European Commission.

Mr Settembri said the company is taking the first concrete steps to achieve its packaging ambitions.

“Nestlé supports the Plastics Strategy of the European Union. We share the vision that no plastic packaging ends up in the environment. Recyclable packaging, good recycling infrastructure and more use of recycled material will help us close the loop,” he said.

City of Yarra uses recycled glass and plastic in road resurfacing

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.

Victorian recycling research and development grants now open

Sustainability Victoria has opened applications for Research, Development and Demonstration Grants of up to $200,000 for projects that can increase the quality of recycled products sold in Victoria.

Businesses, local governments and researchers can apply for grants between $50,000 and $200,000 to help stimulate markets for products made from recovered resources.

Projects that investigate one or more materials which have specific supply or demand side barriers which could be overcome with support from the government are encouraged to apply.

Concrete and brick, electronic waste, glass, organic material, paper and cardboard, plastics, rubber and textiles have all been identified as targeted materials for the grant.

The grants have been designed to support the industry in commercialising new products and processing approaches and to increase the end market uptake and demand for the targeted materials.

Successful applicants will have their projects matched dollar for dollar by the state government.

Previous research projects included alternative uses for glass fines and flexible plastics in construction and manufactured products, such as railway sleepers, plastics in concrete footpaths, glass in non-load bearing concrete and roof tiles made from glass waste.

Sustainability Victoria CEO Stan Krpan said the grants would increase job creation, develop quality products for end markets and increase investment in products made from recovered resources.

“Recent shifts in the current international recycling in gives Victoria greater impetus to develop local markets for the products we can recycle,” Mr Krpan said.

“It is crucial such markets are developed so the value of recovered resources is realised.

“This funding provides industry the opportunity to develop and trial new or existing products and specifications that use significant and reliable quantities of targeted materials,” he said.

The program will also inform the industry of the possible opportunities to use recovered materials in manufacturing to support using products made from recycled content.

“Recycling is an increasingly important community issue, and we are committed to maximising the opportunities to support new markets that use significant and reliable volumes of priority materials,” Mr Krpan said.

“It’s also an opportunity for universities and industry to work together to develop practical solutions to an important, and costly, community issue, which will benefit us all.

New information on Tasmanian Container Refund Scheme released

A Tasmanian round table discussion has seen local government and the waste industry agree to the creation of a Waste Action Plan, amid the release of a report on the potential framework for a Container Refund Scheme.

Consulting firm Marsden Jacob Associates (MJA) has detailed the model framework for a Tasmanian Container Refund Scheme (CRS).

The report concluded the scheme should include common features with similar schemes, such as the eligible containers and price.

Related stories:

It has allocated 18 months to set up the scheme and found the total funding requirement over 20 years would be $239 million, of which $138 million are refunded deposits. The costs of running the scheme were found to be around $101 million, or 4 cents per eligible container.

A redemption rate of at least 80 per cent was outlined, with a target of at least 60 refund points. Graduated sanctions were recommended for failing to meet these targets, with a verifiable auditing and tracking system required to ensure the objectives are met.

Potential cost savings for local councils were found, with beverage container litter estimated to fall by half, with an 80 per cent redemption rate.

MJA said in the report that the market should be allowed to determine the operational details of the system. The firm estimates nominal price impacts on consumers who don’t redeem the containers would start at around 10 cents per container and rise over time to 16 cents, with cost impacts on redeemers being around 10 cents lower.

Another finding from the report said the CRS should be run by a single co-ordinator and operator, set up as a product stewardship organisation (PSO). This PSO would be overseen by a board of directors that is representative of the industry and ensures access to relevant expertise.

The Action Plan will aim to consider initiatives like the CRS as part of the broader context across Tasmania. It will be further developed following China’s increased restriction on solid waste imports.

With the implementation of stricter contamination levels for imported waste, the amount of recyclate and waste that it will accept has decreased significantly, affecting Australia’s waste industry.

Tasmanian Minister for the Environment Elise Archer said the government will continue to consider the views of local government, industry, business and the community regarding a CRS and a range of other initiatives in developing the Waste Action Plan.

Local Government Association of Tasmania President Doug Chipman said that local government has welcomed the round table.

“The impacts of China’s restrictions are being felt deeply by councils and the community’s interest in waste management in general has risen significantly,” Cr Chipman said.

“We have five motions on waste at our upcoming LGAT General Meeting and I look forward to collaborating with the State Government in addressing these issues.”

ACT CDS locations announced as scheme begins

The first locations for the Australian Capital Territory’s Container Deposit Scheme (CDS) have been announced.

The scheme commenced on 30 June 2018 and refunds consumers 10 cents for returning an eligible container.

The scheme targets containers that occur most often in the waste stream of ACT, covering glass, PET, HDPE, aluminium, steel or liquid paperboard cartons, between 150 millilitres and three litres in size. The scheme does not include plain milk containers, flavoured milk containers above 1 litre, pure juice drinks, wine, spirit or cordial bottles.

Director of ACT NoWaste Michael Trushell said a total of nine return points will open across Canberra’s north and south side with more locations to join over the next 12 months.

“To receive a 10 cent refund, residents will be able to take their eligible containers to two types of return points, express return points for returning up to 500 containers or bulk depots, which can accept any number,” he said.

“The ACT CDS is a little different to the one that operates in NSW. Residents can choose to collect the refund or donate the funds directly to a charity. Social enterprise groups like the Salvation Army and St Vincent de Paul have express shopfronts across Canberra that will benefit from the scheme.”

The locations include:

  • 151 Gladstone Street, Fyshwick (bulk depot)
  • 10 Buckland Street, Mitchell (bulk depot)
  • 1/9 Wooley Street, Dickson (express return point Vinnies)
  • Corner Pitman Street and Athllon Drive, Greenway (express return point Vinnies)
  • Corner Rae and Purdue Streets, Belconnen (express return point Vinnies)
  • Corner Anketell and Reed Streets, Tuggeranong Square, South Greenway (express return point Salvos)
  • Shop 7, Corner Hindmarsh Drive and Botany Street, Phillip (express return point Salvos)
  • 32 Hoskins Street, Mitchell (express return point Salvos)
  • 15 Mildura Street, Fyshwick (express return point Salvos)

“I would like to thank the Network Operator, Return-It and the Scheme Coordinator, Exchange for Change ACT for working behind the scenes to establish the first CDS for Canberra,” Mr Trushell said.

Lake Macquarie City Council push to swap sand with recycled glass

Recycled crushed glass will substitute sand in civil works projects as Lake Macquarie City Council pushes for local solutions to national issues.

The project aims to reuse thousands of tonnes of glass every year, with the potential to reuse 12,000 tonnes collected from across the Hunter region if other councils get involved.

Related stories:

A plant built on the Central Coast is manufacturing the glass sand for the council’s trial.

The sand has similar applications to normal sand and can be used as a bedding material in drainage projects and other civil works.

Lake Macquarie Mayor Kay Fraser said glass bottles, jars and other items collected from household recycling bins would be sorted and processed as usual at a materials recovery facility at Gateshead.

“There is a growing need across Australia to find an end use for recycled glass,” Cr Fraser said.

With companies finding it cheaper to import new glass than buy recycled, we need to start coming up with innovative, cost-effective alternatives.

“This collaborative project could help solve a national crisis in our own backyard,” she said.

Manager Planning and Sustainability Alice Howe said more than 5000 tonnes of glass were collected for recycling annually across Lake Macquarie.

“Our strategy is twofold: we are demonstrating the suitability of recycled glass sand for our own civil works program, and have amended our engineering guidelines to specify how this material can be used in development across the city ,” Dr Howe said.

“We aim to gradually increase the amount of recycled glass that is processed into glass sand and used in our own operations. If the rest of the region follows our lead, this initiative could close the loop on thousands of tonnes of glass each year.”

Dr Howe said if the end-use issues for recycled glass aren’t addressed soon, the stockpiles of material will continue to grow.

Glass and plastics could be used to help build footpaths

End-of-life plastics and glass fines could soon be used in the construction of footpaths instead of going to landfill, according to a new study from the Swinburne University of Technology.

The research found plastics and glass fines could be incorporated into concrete footpaths while still meeting the standard requirements, and without compromising the mechanical properties.

Related stories:

It is estimated that approximately 100,000 tonnes of flexible plastics end up in landfill each year, and only 48 per cent of glass waste is recovered for recycling, according to Sustainability Victoria.

The next step for this project is to include local governments and industries to increase the amount of recycled content in footpath construction.

“The use of recovered plastics and glass fines in concrete footpaths will divert significant quantities of these materials from landfill, while reducing the demand for virgin construction materials,” said Swinburne University of Technology’s Dr Yat Choy Wong.

This research project is one of seven projects that investigate new ways to increase the use of recovered class and flexible plastics.
