Statewide Recycling Services has saved thousands of dollars each week in transportation costs after purchasing a PBS-approved Freighter six-axle Dog trailer.
We spoke with City of Swan Manager Fleet and Waste, Colin Pumphrey, about the municipality’s approach to upskilling its staff and waste management strategy.
Green Distillation Technologies has announced its extra-large tyre recycling plant will open in Perth, Western Australia in June 2018.
The venture is a collaboration between the Tytec Group and Green Distillation Technologies. They have jointly established Perth based Tytec Recycling Pty Ltd to undertake economic green recycling of large tyres. Referred to as off the road tyres (OTR), they are classified as those with rim sizes ranging from 25 to 63 inches and are used on the large mining dump trucks.
GDT has developed Australian technology that will recycle end-of-life tyres into oil, carbon and steel using their destructive distillation process. Transport of tyres from mine sites around Australia to the recycling plant will be undertaken by Tytec Logistics which has over 75 per cent of the national OTR logistics market, as well as providing storage for the extra-large tyres.
The plant, which will completely recycle the whole tyres and not cut or crumb the rubber, will be located on the Tytec facility at in the Perth suburb of Welshpool. It will have a capacity of 5,000 tonnes of OTR tyres per year, which will amount to over 2 million litres of oil, approximately 2,000 tonnes of carbon and 1,000 tonnes of steel.
The actual cost of the plant is based on engineering estimates of $8.5 million and will be quantified once the final engineering and construction contracts have been determined. The OTR plant differs from a conventional passenger/truck tyre recycling plant as the chamber will be ten times larger and consequently the material cost will be significantly higher.
New technology implemented by Cleanaway will help local councils answer queries from residents on the status of their bin pickup, and be informed when a scheduled job has been completed.
Technology on-board Cleanaway vehicles will provide near real time information on the company’s truck locations, allowing it to better manage waste collected in weekly kerbside pickups.
It comes as the company prepares to launch its Cleanaview technology in Noosa Council, Queensland on 1 September, followed by The Hills Shire, NSW on 2 October.
Cleanaway aims to help educate residents about what can and can’t be disposed of through their local collection, and how they can safely dispose of other materials. It is also looking to help improve the quality of recyclables delivered to its Material Recycling Facilities and reduce the amount of contaminated materials which end up in landfill. Importantly, it also means that it can ensure prohibited and potentially dangerous materials don’t end up in landfill, and can be safely disposed of.
The Federal Government has announced funding support for the South Australian Government’s $155.6 million Northern Adelaide Irrigation Scheme.
The scheme will deliver an additional 12 gigalitres a year of recycled water from the Bolivar Wastewater Treatment Plant.
Upgrades will be made to the Bolivar Wastewater Treatment Plant to deliver the additional recycled water, as well as a new pipe network north of the Gawler River.
Once necessary approvals are in place, construction will take approximately a year and a half.
The new infrastructure will be built with the ability to increase capacity to 20 GL a year, as demand and access to overseas markets grow.
An independent economic assessment conducted for the SA Government has identified the extra 12 gigalitres of recycled water a year would create 3700 jobs in the region and add $578 million a year to the state’s economy – growing to 6,000 jobs and $1.1 billion a year when at the full 20 GL capacity.
The City of Swan’s recycling centre has officially opened, using recycled products in the construction of its new facility.
Opening the Bullsbrook Recycling Centre last week, Western Australian Government Environment Minister Stephen Dawson praised the city for its environmentally sound design.
All the roads and hardstands within the recycling centre were built using recycled road base materials and the on-site sheds have been re-used from the previous property owners.
The recycling centre, located between the Bullsbrook and Ellenbrook town centres, will provide the community with a year-round facility to sort, recycle and re-use unwanted bulk items and waste materials. It will be free for all City of Swan residents.
It forms the first stage of what will become a sustainable hub for the area including a tip shop, community workshops, community gardens and education centre.
“This new facility will help reduce the amount of material picked up in verge bulk collections and reduce the amount of waste going to landfill,” said Environment Minister Stephen Dawson.
“This facility is a great example of collaboration between the State and local governments, providing fit-for-purpose infrastructure to the community.”
Researchers from Edith Cowan University have developed a way to modify the atomic structure of iron to create a metal which they say can strip impurities from water in just a few minutes.
The research, recently published in the journal Advanced Functional Materials, offers new applications in the mining, textile and other industries where large amounts of wastewater are
Associate Professor Laichang Zhang from ECU’s School of Engineering was able to change the atomic structure of iron to form what is known as metallic glass.
Metallic glass gets its name not from the fact that it is transparent and can be used in windows, but because its atomic structure resembles that of glass.
Whereas the atomic structure of traditional metals is very ordered, with the atoms forming a grid like structure, metallic glass atoms have a much more disorganised composition.
“It is this disordered atomic structure that gives metallic glass its very interesting and useful characteristics,” Professor Zhang said.
Saving waste water
A thin strip of the iron-based metallic glass developed by Professor Zhang can remove impurities such as dyes or heavy metals from even highly polluted water in just minutes.
“It works by binding the atoms of the dye or heavy metals to the ribbon, leaving behind useable water,” Professor Zhang said.
“This offers a number of benefits compared to the current method of using iron powder to treat wastewater. Firstly, using iron powder leaves you with a large amount of iron sludge that must be stored. Secondly it is expensive to produce and can only be used once.
“In contrast, the iron-based metallic glass we have developed can be reused up to 20 times, produces no waste iron sludge and can be produced as cheaply a few dollars per kilogram.”
Professor Zhang said the technology could have significant applications in the textile and mining industries.
“Mining and textile production produces huge amounts of water that is contaminated with heavy metals and dyes respectively,” he said.
“We have already had significant interest from companies in both China and Australia who are keen to work with us to develop this technology, including Ausino Drilling Services, whose clients include Rio Tinto and the Aluminium Corporation of China.”
Both Ausino Chief Executive Officer Dr Minlu Fu and Vice General Manager of Beijing Wuyi Environmental Technology Ltd Mr Yeqiang Wu said they were looking forward to collaborating with Professor Zhang.
“Our experts noticed that Laichang’s recent research using metallic glass as a catalyst for ultrafast water purification is very achievable in the industrial application,” Dr Fu said.
A joint project involving Sustainability Victoria, Bass Coast Shire and neighbouring councils has netted 653 kg of dangerous chemicals during a two-hour Detox Your Home collection at Wonthaggi.
Sustainability Victoria’s Resource Recovery Group Director, Jonathan Leake, said more than 300 kg of flammable goods were brought in by 30 people to the first collection of the financial year.
“‘Detox Your Home’ is a safe, free and easy-to-use service that diverts hazardous good from landfills and lets you dispose of common household chemicals without harming your health or the environment.”
“In this case an average of 21kg per person was brought in. It’s an indicator of what else is out there.”
Detox Your Home is administered by Sustainability Victoria delivered in partnership with local councils and is funded through the landfill levy. Products collected are recycled and diverted from landfill.
In the 2016/17 financial year, nearly 73 tonnes of chemicals were collected at 30 metropolitan and country Detox Your Home activities across Victoria.
