Melbourne opens recycling hub EOI’s

The City of Melbourne is seeking innovative technological solutions to expand its network of rubbish and recycling hubs throughout the central city.

Lord Mayor Sally Capp said expanding the hub network would streamline collection services and improve public amenity.

“We know there are around 1000 individual bins stored on public property across the central city. Bins in laneways take up space and can cause odour, visual pollution and attract vermin,” Ms Capp said.

“Over the long-term, businesses would be encouraged to use the communal network of resource recovery hubs instead of using on-street bins. As the network expands over time, the number of on-street private waste bins will be reduced.”

Ms Capp said council is asking companies to submit proposals for specialised waste and recycling collection services.

“We will consider everything from mini-compactor bins to specialised vehicles and collection of source separated materials such as glass, organics, paper and cardboard,” Ms Capp said.

“We could tailor our network of hubs to the profile of key precincts around the city. For example, we could deliver more food waste and plastic recycling hubs in our hospitality precincts.”

Ms Capp said council was looking at densely populated international cities such as Milan, which has one of the highest recycling rates in Europe.

“We want to expand our network of waste and recycling hubs to transform the way waste and recycling is collected in the central city,” Ms Capp said.

“Rather than have multiple trucks circling the city, we want to create more communal hubs so businesses can take their items to a local collection point.”

Ms Capp said since 2013, the City of Melbourne has removed more than 500 bins off the streets by providing access to communal garbage compactors and recycling hubs.

Environment Portfolio Chair Cathy Oke said residents and businesses have a critical role to play in helping to reduce waste and find local solutions to the state’s recycling crisis.

“Unfortunately, tonnes of recycling is being sent to landfill, so the most important thing people can do right now is to try to avoid creating waste,” Ms Oke said.

“The City of Melbourne understands this is a state-wide issue and we will continue to examine potential short and long-term solutions such as new technologies.”

Ms Oke said council is also asking residents and businesses to adjust their behaviour to achieve long-term change.

“This means changing the products we buy to ones that have less packaging or things that can be re-used in our homes or workplaces,” Ms Oke said.

“Food waste is an area that almost anyone can cut down on by starting to compost or simply using leftovers to make a new meal instead of throwing them out.”

The City of Melbourne is specifically looking for solutions that include:

— Wi-Fi or radio frequency identification technology that can charge users for the amount of waste calculated / disposed.

— Smart, card, tap technology which can bill users via a pay-as-you-throw waste management system.

— Smart sensors and bin weights to monitor bin levels.

— GPS tracking to help truck drivers know when a bin needs emptying.

— Ability to compact a variety of waste streams for easier storage and collection.

ACOR and MRA propose one-off $150 million recycling payment

The Australian Council of Recycling and MRA Consulting Group have estimated that a one-off payment of $150 million could de-risk and on-shore Australia’s recycling sector through three actions.

Actions include $90 million to retrofit materials recovery facilities to improve sorting, a positive procurement policy to ensure products with recycled content are purchased in Australia and community education to reduce contamination in recycling systems.

In a media statement, MRA welcomed the Council of Australian Governments (COAG) decision to address the many difficulties facing the recycling and waste management sector.

At its meeting of 9 August, COAG announced it would establish a timetable to ban the export of waste plastic, paper, glass and tyres, while building Australia’s capacity to generate high value recycled commodities and associated demand.

MRA Managing Director Mike Ritchie said since China’s National Sword restrictions, the recycling industry has been calling for government intervention to support domestic recycling activities.

“According to the 2018 National Waste Report, Australians generate 54.5 million tonnes of waste per year and we successfully recycle over 31.7 million tonnes of that or 58 percent,” Mr Ritchie said.

“Of that, 4.3 million tonnes is exported, primarily fibre and plastic. This 4.3 million tonnes is now subject to greater import restrictions by the Asian manufacturing nations, as they grow their own domestic recycling industries.”

Mr Ritchie said Australian needs to rebuild its own on-shore reprocessing capacity to avoid fibre and plastic going to landfill.

“That means plastic reprocessing facilities to turn used bottles into plastic pellets, and reusing fibre in recycled paper here in Australia. We know how to do it but the economics have always favoured export,” M r Ritchie said.

“To close the loop in Australia we will need governments and businesses to preferentially purchase materials with recycled content.”

Mr Richie said government needs to introduce recycled content rules for domestic manufacturers, and have purchasing policies in place that require recycled content.

“The most obvious are converting glass bottles into sand for use in road base, and asphalt and reprocessing plastic bottles into asphalt, furniture and fuel. Governments also need to mandate the use of recycled paper” Mr Ritchie said.

“Recycling doesn’t stop at putting the bin out on the kerb, it stops when a product using recycled material is sold back into the economy. If we want to truly close the loop then we need to purchase and reuse products with recycled content.”

BINGO announces financial year results

BINGO Industries has announced its financial year results, with net revenue up by 32.4 per cent to $402.2 million and underlying earnings before interest, tax, depreciation and amortisation (EBITDA) up by 13.2 per cent to $106.1 million.

BINGO Managing Director and Chief Executive Officer Daniel Tartak said business performed broadly in-line with the prior financial year, in what was flagged as a transitional year for the business following its Dial A Dump (DADI) acquisition.

“The acquisition of DADI has materially changed our business, and we’ve made great progress since integrating DADI into our operations,” Mr Tartak said.

“The contribution from DADI since the completion of the acquisition was in-line with expectations. The asset base we’ve secured through the acquisition will help transform our business for many years to come, while supporting our vision for a waste-free Australia.”

Collections revenue was up 20.7 per cent to $213.5 million, which Mr Tartak said was largely driven by a full year contribution of the Victorian business and a partial year contribution of DADI collections revenue.

“Our Post-Collections infrastructure assets now account for approximately 63 per cent of our EBITDA and continue to support the repositioning of the business,” Mr Tartak said.

“We’ve had more than two years of constant activity and investment since our IPO and we now expect to start reaping the financial benefits. We’ll begin to see the positive cash flow impacts from Patons Lane, West Melbourne and a full year run-rate of DADI in FY20.”

Vivo Mobile joins MobileMuster

Smartphone manufacturer Vivo Mobile has joined the mobile telecommunication industry’s recycling program and product stewardship scheme MobileMuster.

Australian Mobile Telecommunications Association Chief Executive Officer Chris Althaus said the program recovers over 95 per cent of the material in a mobile phone, which is then reused to manufacture new products.

“The mobile telecommunications industry is delighted to welcome Vivo Mobile to our world-class recycling program,” Mr Althaus said.

“Our members work together to ensure we keep old mobiles out of the general waste stream and recycle them in a responsible, secure and environmentally sound way, placing reusable commodities back into the supply chain.”

Vivo Mobile Chief Executive Officer Fred Liu said the company was excited to join the government accredited program, as it looks to enter the Australian market.

“Being part of this industry led initiative gives us great confidence that when our customers have finished using their smartphones along with any accessories, they will be recycled to the highest environmental standard,” Mr Liu said.

Since the MobileMuster program began in 1998, it has diverted more than 1400 tonnes of mobiles and accessories from landfill, including over 13 million handsets and batteries.

SA releases Recycling Activities Report

South Australia has achieved the highest diversion rate of any state in Australia, according to the newly released Recycling Activities Survey Report.

Environment Minister David Speirs said South Australia diverted 4.49 million tonnes of material from landfill between 2017-18.

“The state has once again achieved the highest diversion rate of any state in Australia. The increase in our diversion rate is driven by an increase in state infrastructure projects,” Mr Speirs said.

“While all of the long-term key indicators are trending in the right direction, we actually saw a slight increase in waste to landfill from 2016-17 to 2017-18, as well as an increase in waste generation per person, showing we need to remain vigilant.”

According to the report, 87 per cent of the states recovered material is recycled locally.

“Despite considerable impact on recycling as a result of China’s National Sword policy, South Australia’s recycling industry is transitioning by implementing measures to improve the quality of the materials recovered and diverted, and by educating the public on the importance of recycling,” Mr Speirs said.

“Our recycling results are world leading, however, we still have room to improve. South Australia set an ambitious target in 2003 to reduce waste to landfill by 35 per cent by 2020 and we’re at 29 per cent.”

Over 118 individuals from South Australian organisations involved in resource recovery were surveyed for the report.

The survey asked participants to provide the value per tonne of each material stream reprocessed by their organisation.

Using this data, the report lists metal as the greatest contributor to the market value of resource recovery at $177 million, followed by organics at $101 million and cardboard and paper at $40 million.

The overall market value of the South Australia resource recovery sector is estimated at $356 million.

Additionally, the survey highlights masonry and soil as the highest recovered material streams at 30 per cent, followed by organics at 24 per cent and metals at seven per cent.

The report was prepared by Rawtec for Green Industries SA.

Scott Morrison visits Downer CDEnviro recycling facility

Prime Minister Scott Morrison and Industry, Science and Technology Minister Karen Andrews have visited Downer and CDEnviro’s processing facility and asphalt plant.

During the visit, the Federal Government announced it would commit $20 million to grow Australia’s domestic recycling industry.

Downer Reconomy General Manager Jim Appleby said while visiting the facility, Mr Morrison highlighted the government’s support for recycling infrastructure, research and development and positive purchasing.

“It’s amazing to hear the government talking about turbocharging the recycling sector,” Mr Appleby said.

“We are really proud of this facility and how it’s transforming the way Australia sees waste, so it was great to demonstrate this to our Prime Minister and our Industry, Science and Technology Minister.”

Mr Appleby said Mr Morrison highlighted Downer’s sustainable Reconophalt asphalt product as innovative recycling.

“The Reconomy facility in Rosehill Sydney features state-of-the-art street sweeping recycling technology from waste management solutions company CDEnviro,” Mr Appleby said.

“There’s recycling and then there’s revolutionary recycling, and we want to demonstrate that revolutionary recycling is what the world needs.”

The facility annually diverts more than 21,000 tonnes of waste from Sydney road construction projects.

“This material is then used in road construction and applied as asphalt to the road networks from where the material originated,” Mr Appleby said.

“Reconomy and CDEnviro share a purpose in championing sustainability and zero waste.”

East Waste to commission electric waste collection truck

Adelaide waste and resource recovery authority East Waste will commission South Australia’s first fully electric-powered waste collection truck in December.

East Waste will install a 30 kilowatt solar system at its Ottaway depot to provide renewable energy to charge the truck’s batteries.

The truck, supplied by Australian company Superior Pak with drivetrain technology from SEA Electric, will be the first in a fleet replacement program.

East Waste Chairman Brian Cunningham said the new truck will replace a diesel-powered truck and remove the equivalent of 20 vehicles generating 63 tonnes of carbon dioxide every year.

“This is much more than a terrific environmental initiative by East Waste. It will create financial gain to better manage the cost of kerbside collections of recyclable resources and waste,” Mr Cunningham said.

“We conservatively project that our new electric truck will save in excess of $220,000 over the seven-year life of a diesel truck.”

Mr Cunningham said the truck’s drivetrain generates electricity each time it reduces speed, which returns charge to the batteries.

“Residents in suburban streets will fall in love with our new truck without realising it,” Mr Cunningham said.

Electric vehicles hit the road

Waste Management Review talks to the stakeholders involved in trials of electric vehicles trucks to find out the challenges and opportunities behind the burgeoning technology.

In recent months, electric vehicle (EV) trials have been taking off with private waste management companies and councils across the country.

The City of Belmont, about eight kilometres east of the Perth CBD, was announced as the first site in WA for SUEZ’s fully EV truck.

Two months later, Cleanaway announced the first of two fully electric waste collection vehicles had begun kerbside collections in Victoria as part of a three-month trial.

Hobsons Bay at the time of writing had begun servicing households, while Mooney Valley had also planned to host the vehicle. Another trial in a council yet to be announced will also take place in WA.

The trial aims to ensure the vehicles will be tested across a variety of terrains and municipal settings.

As early as the 2018 Melbourne Waste Expo, WM Waste Management Services announced its plans to test three electric trucks with the City of Casey in Melbourne. These began over the past few months.

All EV-powered drive trains were fitted by SEA Electric with a Superior Pak body. In the City of Belmont, SEA Electric estimates the EVs will save around 35,000 litres of diesel each year and avoid around 90 tonnes of CO2 emissions annually.

The noise levels are significantly reduced and reportedly akin to a whisper. The EVs are also presumed to offer significantly reduced maintenance, operate for more than 150 kilometres uncharged and have zero emissions from the vehicle.

EVS ON-BOARDING

Cleanaway is working towards zero-emissions vehicles by powering its EVs with its own renewable sources of electricity generated in other parts of the business.

Cleanaway Head of Fleet Paul Young tells Waste Management Review the EVs conversation started with SEA Electric and Superior Pak around 12 months ago. Superior Pak supplied and electrified the chassis and provided the body.

“It ties very clearly into our company mission to make our operations as environmentally sustainable as possible,” Paul explains.

He says that by not waiting for an original equipment manufacturer (OEM) solution, Cleanaway also identified an opportunity to be a market leader.

“We have a high level of inquiries mainly from our municipal customers around energy and being green so that is why we went down this path.

“We use the term trial, but the assets we’re building are starting the process. We’re not trialling and taking them out. They form part of our fleet like any other asset and we expect the asset to be operational like all other vehicles.”

Once the EVs have been tested by both SEA Electric and Superior Pak (SEA Electric tests the asset by running the vehicle for around 100 hours), they are sent off to the Cleanaway depot, where drivers undergo training by Superior Pak with SEA Electric.

SEA Electric continues to work with the drivers to optimise the vehicle for performance even as the driver is operating the vehicle.

Paul says the body operation is exactly the same as standard diesel vehicles with no changes to the mechanics of the operation.

He adds that another difference is that batteries will be replaced for longevity compared to engine rebuilds for diesel.

Paul says the noise reduction is significant. When it comes to wear and tear, the brakes are considered regenerative, lowering the number of brake pad changes required.

This means that during braking, rather than solely using the conventional brakes, the electric motor acts as a generator to provide a charge to the batteries. As well as providing a useful battery top up, Paul says this is expected to significantly reduce brake wear and subsequently repair and maintenance costs.

“While it is very early days, from a long-term cost perspective we see the benefit in reduced maintenance and fuel. However this will need to be monitored as the vehicle ages to verify the benefits.”

Paul says the vehicles are compliant with National Heavy Vehicle Law and other standard regulations.

While the batteries have added some weight to the vehicle, Paul says he expects this to shift over time.

For the time being, a minor compromise has been made on payload to gain the other benefits.

THE SETUP

Tony Fairweather, Group Managing Director at SEA Electric, says the entire power system is electrified.

This not only includes the battery and electric motor for direct drive to the existing differential, but all of the ancillaries such as air conditioning and heating for the cab, power steering, air compressor for braking and a 22-kilowatt on-board charger.

Tony says SEA Electric began developing the power system (known as SEA-Drive) around 2013.

He says that the company waited for the price of batteries to drop below USD 300 per kilowatt hour (kWh) before coming to market in early 2017.

Tony says that other than OEM chassis selection by the customer, most vehicles deployed to the various councils are largely similar in power system design and performance.

“In the three-axle rigid segment, we commenced with a 180kWh battery pack. However, due to the evolution of batteries and volume over time, our supplier is now able to offer 216kWh in the same size battery pack, which will increase further in the near term.”

He says the electric motor offers around 3500 newton metres of torque and 350kW of power. The vehicles charge in about eight hours (using the on-board charger), but have the ability to charge with (up to) 120kW DC charger and permit about 3500 charge cycles with a 10-year lifespan.

“We run about 700 kilograms heavier than the original tare weight of the internal combustion engine cab chassis which is around five to six per cent heavier. However as the battery density increases, this will reduce over time.”

The trucks are all fitted with an onboard charger, as this segment will typically require a duty cycle to be completed on a single charge, before returning to base to charge with a standard three-phase, 32A power point.

Tony says the vehicles charge during off-peak energy periods in the evening, which is cost-effective for operators, with the option of deriving their energy from non-renewable sources in the grid.

He says that now that the EVs have been tested, the next step is educating buyers who may be apprehensive. Tony notes that in California, buyers are offered up to $165,000 rebate to purchase an electric refuse truck while New York, Texas and Florida are expected to take on similar programs.

He says that given the duty cycle and relatively low kilometres of refuse vehicles, the business case is a no brainer for those in the metropolitan region, with a payback period of about four years without incentives.

He says there is also no risk of battery fires in the electric EVs as the batteries are large and operate at much lower temperatures than smaller EV batteries.

Tony says the next steps are also to work towards increasing government support. He says that Heavy Vehicle National Law regulations around gradeability and noise need to be updated to ensure that EVs don’t have to go to the mainly irrelevant process of complying with Vehicle Standards Bulletin 6 (VSB6).

Michael Strickland, WM Waste Management Services Project Manager, says that the provision of EVs in its service proved an important factor to winning a tender with the City of Casey.

The company currently has three EV compactor trucks as part of its newly acquired contract. It is looking at additional EVs in single axle and has already seen the benefits firsthand of reduced noise.

He says the vehicle uses a lot of power when picking up high speed on the freeway, so it’s about minimising travel time.

While it is still early days for the EV trial, Michael says a few issues are still being ironed out.

“Part of the issue is the trucks were modified and weren’t from the factory floor and with the EV factor, the floor truck had difficulty registering as there are a lot of different design rules,” Michael says.

Michael says initial computer teething issues have been sorted, although the company is getting around 140 kilometres of trips before a charge is needed. To ensure the collection run goes smoothly, start and finish crews work around this, ensuring WM Waste Management Services is able to get two runs a day.

BARRIERS TO ENTRY

A Senate select committee released recommendations earlier this year into increasing the uptake of EVs in the car, truck and bus sector. Some of the recommendations included that the Federal Government develop a national EV strategy to accelerate uptake and manage the risk and transitions of the vehicles.

Dr Peter Hart, former Chairman of Australian Road Transport Suppliers Association, welcomes the shift to electrification but is yet to be convinced of their effectiveness in refuse applications.

“The amount of energy you can store in one litre of battery is still only a fraction to that that can be stored in one litre of diesel fuel, so EVs will be advantageous where energy can be scavenged,” Peter says.

“I think lithium battery technology is advancing rapidly and energy density will continue to increase.

“There are safety issues you run into if you try and get too much energy into a given space. At present, technical standards do not adequately require protection against signs of internal battery degradation.”

He says like any new technology, the EVs will require trial and error to ensure the systems integrate.

“The key success factor for EVs in the waste industry will be to recover more than 50 per cent of the energy used to accelerate the truck from one pick-up point to the next, and to lift the bin. If this can be achieved, the range problem will be solved and the economics will be favourable.”

Charging points will also need to be kept out of the weather to prevent safety risks.

“If you went back a few years, everyone was interested in EVs for long distance haulage, but the reality is we can’t store enough energy so people are now interested in hydrogen fuel cells. In the metropolitan area around deliveries I think EVs will have a significant advantage.”

He says that battery fires are a risk. Lithium ion batteries should be charged using a battery management system that varies the charging voltage to individual cells to avoid over-charging. Peter says that EV trucks must have a well-designed battery management system.

Peter’s call to action is for the development of national (and international) standards that define good practice. He hopes the outcome of trials of EVs in the waste industry will be successful.

Victorian Waste Management Association (VWMA) Executive Officer Mark Smith says that those businesses who are testing and piloting EVs are also testing and piloting the re-sell value of these vehicles.

Mark says that as Australians see cheaper power provided to the national grid, EVs will effectively offer a competitive alternative to diesel and even beat the running costs for standard vehicles in urban/inner city environments.

The Komptech Metalfex

Increasingly stringent standards for recycled organic waste products such as compost and mulch have driven demand for innovative separation solutions. While many products exist for ferrous metals separation, non-ferrous separators have largely been confined to stationary applications like materials recovery facilities. Komptech has responded with a mobile solution that combines ferrous and non-ferrous metal separation: the Komptech Metalfex.

Designed for conveyor feed, the Metalfex has a typical overband ferrous separator. It removes non-ferrous metals using an eddy current separator with eccentric pole system, discharging the metals and the cleaned fraction via two folding conveyors to the left and right of the machine. Like many of Komptech’s hybrid power units, the Metalfex’s components are electrically powered, either from the on-board diesel generator or from the grid. It is available in compact hooklift, easily manoeuvrable two-axle trailer or mobile site chassis versions.

The Metalfex can be used with shredded waste wood and bulk waste, industrial and commercial waste, household waste, mixed construction waste and shredder output. With its tough, powerful design, it can take input grain sizes up to 300 millimetres in an extremely wide range of materials.

The first Metalfex arrives in Australia later in 2019. ELB Equipment, Komptech’s distributor in Australia & New Zealand, is currently booking demonstrations.
