ACT opens bulky waste collection tender

The ACT Government is seeking applications for a service provider to implement its bulky waste collection service, expected to roll out mid-2020.

City Services Minister Chris Steel said local industry participation will be a key evaluation criteria in the selection process.

“The government is cracking down on illegal dumping, but at the same time we will also provide an accessible service for households to drop off unwanted bulky items to encourage good behaviour,” Mr Steel said.

“Greater weighting will be given to tenderers that can demonstrate a commitment of engagement and involvement of local businesses.”

The rollout of bulky waste will see each household receive a single collection per year of up to two cubic metres for items including damaged furniture and worn-out household appliances.

According to Mr Steel, residents will be able to book collections online, with exact service details to be determined in consultation with the service operator.

“We’ve rolled out green bins across the city and we’re rolling out bulky waste collection to provide better city services in Canberra,” he said.

Tackling the food revolution: Loop Organics

Loop Organics is working with the end-to-end users of organics, delivering high-value crops and supporting NSW farmers during the recent drought.

While there is no universal definition of drought, NSW is experiencing one of its most severe droughts on record, with extreme low rainfall affecting farmers over the past six to nine months.

As governments around the world deal with climate change and its impact on multiple sectors, one solution being proposed to support the agricultural sector is sustainable intensification. In a nutshell, sustainable intensification sees better optimisation of resources while using fewer inputs and producing greater yields.

This paradigm shift is already being driven by multiple organisations across Australia, including Loop Organics. The company has managed to get high crop yields using organics wastes from food manufacturing where the majority of the state is in drought, and in turn supply fodder to NSW farmers experiencing drought.

Loop Organics has donated bales of oaten hay grown in the winter of 2019 to farmers in the Northern Tablelands and Lower Hunter Valley area, closing the loop between food processors and primary producers and creating healthier soils that can support ongoing agricultural production.

With a combined experience of more than 60 years, the team at Loop Organics have a wealth of experience in a broad range of organics management areas. The company has presided over some of the largest liquid organics and biosolids reuse programs in Australia. Its services comprise composting, wastewater lagoon desludging and dewatering, collection, transport and land application of both liquid and solid organics.

Loop’s staff has provided consulting and contracting services to water authorities and councils since 1994. The company operates large-scale biosolids management and reuse programs for a number of east coast water authorities and food processors.

In the Sydney Basin, Loop Organics receives waste from milk producers, chicken abattoirs, yoghurt culture manufacturers and a range of other sites. Loop Organics works on farms on the outskirts of Sydney. In some cases, the farms have been left for a long period of time without any intensive farming.

Tim Wilson, of Loop Organics, says Loop operate on five farms in the Sydney Basin, close to 1000 hectares of land.

He says that a history of soil compaction is eliminated through deep ripping and delivery of moisture, organic matter and nutrients directly to the root zone. This process mechanically breaks up compacted soil layers and uses strong tynes to loosen hard layers of soil.

“We’ve been able to retain a lot more soil moisture in the dry period so we’re getting high yielding crops where the majority of the state is in drought,” Tim says.

“We’re not using any chemical fertiliser, we’re using a by-product from food generation so it’s sustainable. We’re just returning what’s been taken from the soil, putting it back and getting a high value product out of it.”

Lisa Rawlinson, Loop Organics Director, says that the winter crops are typically oats and in the summer, crops such as sudangrass, millet or sorghum are grown. Importantly, moisture and high value nutrients are returned to the soil at a suitable application rate to produce high value crops which Loop can supply to farmers during periods of drought.

“The production we’re achieving is almost akin to those from irrigation areas and that’s principally because the liquids we’re delivering into the subsoil are being retained, so the crops can withstand the low rainfall drought conditions we’ve been experiencing over recent years,”
Lisa says.

Loop Organics’ Hunter Valley composting facility, located at Ravensworth, is situated within a market with a large demand for organic products and along B-double transport routes. The facility can process up to 55,000 tonnes per year of garden organics and biosolids to create specialised soil amendment products for agriculture and mine rehabilitation purposes.

Matthew Brown, Loop Organics Regional Manager, Hunter Valley, says the company is now looking to grow its Hunter Valley site and is open to new sources of clean material.

“We are hunting for clean, commercial-scale quantity material,” Matthew says.

“At the moment we’ve got the ability to bring green waste in and we’ll look at producing a high-quality compost, targeting farmers and mine rehabilitation.”

He says that Loop Organics is keen to support councils with green waste and food organics services.

“We already have a good relationship with local government, but it’s also thinking about how we can help them in other areas that they have to manage.”

“The compost facility is designed to take materials not just in the Hunter, but also out of Sydney and part of the broader Loop Organics business.

The focus for the future is also for Loop Organics to gain approval to receive, process, decontaminate and compost food organics in the Hunter.

He says the company is looking to the future to ensure it can meet its customer’s needs in three to five and even 10 years’ time.

Team up with maintenance experts to improve the performance of industrial pumps

Replacing a piece of equipment such as an industrial water pump can be a costly and time-consuming exercise. Avoiding the upfront cost and associated downtime, whether through predictive or regular maintenance, can enable extended product lifetimes.

BSC provides a full suite of services for industrial pumps that includes repair and refurbishment, asset care, site installation, commissions, and condition-based monitoring and assessments.

These services are conducted in a manner that directly suits the end users and starts with and understanding of the issues or faults that the pump is experiencing.

“If we’re assessing the condition of the equipment while it’s in an operation, and we’re doing some level of predictive maintenance, then we would be looking for indications that there are flow issues in the pump, from the data that we’re analysing,” says BSC Engineering Manager, Ryan Kendrigan.

“From there we would see if there is wear inside the actual pump housing and if we need to schedule a shutdown to either exchange or repair that pump to get it back to optimal working condition.”

“Once they’ve pulled the pump out then by visual inspection after the pump is disassembled, we can either provide the products for the customer to repair the pump themselves, or we have facilities to repair that ourselves depending on what’s fit for purpose.”

Working with the customer to find the solution that fits, BSC have the capabilities for whatever requirements may arise, according to Kendrigan.

“We have done 24-hour jobs where we’ve ripped the pump out ourselves, had it repaired and then back into service. For swimming pools, we’ve been able to pull the pump out at 7pm and have it back in and running at 5.30am when the filter system starts up again.”

Within this process, whatever the customer’s maintenance program is, BSC draw upon their range of products to find a solution. These include the industry-renowned sealants, protectants and coatings from LOCTITE backed by the world’s leading adhesive company Henkel. BSC Product Manager, Michael Rowe, describes how these fit in.

“There may be a requirement to repair some damage where whatever fluid that has been passing through a pump has either scoured or damaged part of the metal area in there. LOCTITE have a material that will help rebuild and repair a pump back to specification. So, instead of replacing the pump with a brand-new unit, they can do a repair that also reduces the overall cost of maintenance.”

During the operation of a pump, the constant movement of water, slurry, or other liquid wears down the internal parts. The metal or material will erode, needing to be repaired to ensure efficient functioning. As Rowe highlights, LOCTITE products are designed to overcome this reality.

“LOCTITE ceramic coatings such as LOCTITE PC 7227 Brushable Ceramic and LOCTITE PC 7255 Sprayable Ceramic can be applied over the original damaged surface area. Then they use a rebuild product, LOCTITE EA 3478 Superior Metal to build back the actual material of the pump and then they’ll apply another coat of the ceramic over the top of it again – this will bring it back to a nice smooth surface. It will also allow the medium to pass cleanly over those surfaces without building up,” said Rowe.

Henkel Key Account Manager, Neil Board states, “what distinguishes Henkel’s LOCTITE products when compared to other, similar products on the market, is that they are available in different colours, LOCTITE PC 7255 sprayable ceramic is available in Grey or Green, LOCTITE PC 7227 Brushable ceramic is grey and LOCTITE PC 7228 Brushable ceramic is White, the later also being AS/NZS 4020-2002 potable water approved.”

“Those colour differentiation’s allows you to see whether there has been wear,” said Board. “You’ll apply one colour first and then a second coating of a different colour over the top, so that on a visual inspection you can see what’s happening.”

Deciding on the right LOCTITE product to apply is part of the expertise of Kendrigan and other BSC engineers, who decide which solution fits the user’s need best.

“Depending on the overall wear of the pump, the repair work can use a couple of different products,” said Board. “That’s where the BSC engineering team will assess what’s required.”

Importantly, the BSC engineering team don’t just provide access to the products required but forge a partnership with customers to get the job done right.

“We work with our customers to supply them with the right components, and potentially give them the training and advice they will need to make their programs as efficient as possible,” Kendrigan says.

Kendrigan adds: “It’s not a case of supplying a product to a customer and forgetting about them, it’s about how can we make their lives easier and better by the services and solutions that we provide to them.”

Giving back to the land: Enrich360

Brisbane Airport has installed an enrich360 dehydrator at its Skygate Precinct, enabling it to reach its landfill diversion targets and move towards a circular economy.

Last year’s announcement of the waste levy in Queensland created a new business case for Brisbane Airport.

With the levy stimulating additional demand for resource recovery solutions, Brisbane Airport began to look at diverting some of its most prominent waste streams.

Having previously conducted audits into its incoming tonnages, the airport knew food waste was its second biggest input after glass. Moreover, the airport has a target to divert 80 per cent of its total waste from landfill by 2030, with food waste emerging as the low hanging fruit.

Andrew Masci, Environment & Sustainability Adviser, says the airport decided to investigate and identify a suitable food waste service. He says that this was its first foray into non-standard commingled recycled, with the airport also participating in the QLD Government Container Refund Scheme.

In a six-month investigation process, enrich360 emerged as the most suitable choice, with its food dehydrator arriving in February this year and timing well with the levy’s 1 July start date.

Launched in late 2017, enrich360’s program uses a dehydrator to condense food waste into recycled water and biomass that can be utilised as fertiliser or as part of compost. The model is established on a closed loop system where restaurants and food service businesses across the country convert their food waste into rich organic fertiliser to give back to farmers and grow better, more nutritious produce.

The benefits lead to more resources being recovered while replenishing globally scarce nutrients and improving Australia’s low food waste recovery rate. The process works to reduce the volume of food waste by up to 93 per cent and create a sterile and pathogen-free material. In a closed loop reverse logistics process, logistics partner In2food picks up the materials during their usual drop-off route and delivers them to farms.

Brisbane Airport’s Skygate Precinct was chosen as the ideal location for a trial of the dehydrator as it was not too busy and included a range of food outlets in the area.

Enrich360’s suitability centred on Brisbane Airport’s desire to ensure its food waste would always find a home, ensuring it did not go to landfill when the airport didn’t have an end-to-end solution.

“Brisbane Airport is transitioning to a circular economy and that is why enrich360 grabbed our attention. There were different dehydrators in the market, but none offered the full service,” Andrew says.

“It took three months to kick off with a few teething issues, but now we are getting amazing results.”

The results speak for themselves, with enrich360 diverting 5500 kilograms of food waste since commencing its trial in February.

Andrew says that around 11 retailers have so far participated in the program. He say the dehydrator is able to detect whether it is overfilled and unfilled. Depending on moisture content, it takes roughly 10 to 12 hours to produce the biomass.

He says that participating retailers will soon be able to take part in a certification scheme that will allow them to showcase their involvement in the program to their customers. The scheme requires partners to demonstrate compliance to the organisation’s program to be granted an enrich360 certification mark.

As an added benefit, Andrew says that Brisbane Airport is also testing whether single-use compostable items could break down in the machine and support the maturation process.

“What I like about the machine is it takes a lot of different varieties of food waste, including chicken bones. There is very little it can’t handle,” Andrew says.

To ensure the system is commercially viable for operators, enrich360 provides purchase, rent and rent-to-own options – enabling businesses to dehydrate food waste on site and have it collected for farms or off-site composting.

The airport is now looking to expand its programs to the main terminals: a challenging, but ambitious next step.

Dean Turner, enrich360 CEO, says with issues of climate change sweeping through the headlines, the system has never been more timely. He says enrich360 is now getting buy-in from a range of businesses, including retail, restaurants, food outlets and universities.

“One of the interesting things in talking to our other global partners who sell this equipment is it was developed eight years ago, and what we’re feeling is it was eight years to early. Now is the time when people are ready for this technology,” Dean says.

“Certainly we found visitors at the Waste Expo were visiting our stand in droves. Almost everyone wanted to talk about their situation, from manufacturing plant operators right through to large-scale primary producers.”

He adds that primary producers, for example, tend to have massive volumes with high water content and the dehydrator can create a water source and dry output slow-release fertiliser.

“When you dehydrate the food waste, you get a green standard recycled water that can be used for all sorts of end uses, including irrigation.”

Dean says the company is now setting its sights on moving into hospitals and the aged care sector.

“An aged care facility can use the water and fertiliser each day across their grounds, creating a circular economy within their own premises,” he says.

In future, he hopes demand for the outputs will be so high that it creates a commodity that end users are prepared to purchase from the generator.

The mechanical stomach: iugis

Tas Papas, iugis Enterprise Sales Director, speaks with Waste Management Review about working with Veolia to promote on-site recycling and the aerobic digestion process.

While waste occurs throughout the food supply chain, roughly two-thirds of Australia’s food waste is generated in consumer-facing businesses or in the home.

To minimise its contribution to the overall footprint, the City of Melbourne, one of the most populous juristications in the state, installed an ORCA aerobic digestion system at its Degraves Street Precinct in 2017.

Diverting more than 60 tonnes of waste in its first year, the machine uses natural microorganisms to convert food into wastewater, which is then sent directly into the sewer system.

According to Tas Papas, iugis Enterprise Sales Director, iugis introduced ORCA technology to Australia two years ago, after a six-year run in Canada and the United States.

Tas says iugis, an internationally managed service technology company, is committed to changing the way businesses deal with their food waste. He adds that as part of this commitment, iugis has developed a collaborative partnership with Australian waste management provider Veolia.

“We saw Veolia as a business that continues to look for waste technologies beyond landfill, and in the last 12 months, they have been offering our ORCA food waste digester as one of their organics solutions,” Tas says.

“Veolia suggest the ORCA to customers looking for an economically viable way to divert food waste, and while the national partnership is still in its infancy, the future looks very promising.”

The ORCA aerobic digestion process uses natural microbes, which are automatically sprayed into the unit, oxygen and naturally occurring heat to digest food waste down to a liquid.

Tas says once the material reaches liquid form, the ORCA passes it through an in-built filter and discharges it from the unit.

“One of the great advantages of the ORCA, which we refer to as the mechanical stomach, is that the metabolisation and digestion rate is accelerated by continuous feeding,” Tas explains.

“Operators don’t have to wait until the end of a cycle as material can be fed into the machine 24 hours a day – it loves a continuous feed.”

Accoring to a 2019 Blue Environment Report prepared for Veolia, the ORCA produces a 100 per cent diversion from landfill rate. This rate, Tas says, enables iugis to register under the Emissions Reduction Fund.

Through reduction credits, the Emissions Reduction Fund aims to incentivise individuals and organisations to adopt new practices and technologies to reduce emissions. These credits, Tas says, add a layer of economic incentive to ORCA installation.

Another economic benefit, Tas says, is that compared to standard dehydration systems, the ORCA uses minimal energy.

“To dehydrate food, a significant amount of heat needs to be added, which typically comes from a pump that requires three-phase power,” he says.

“The ORCA on the other hand, only uses single phase power, so a standard 10-amp power point is all that’s required. Operationally, it’s very cheap to run.”

In addition to landfill diversion and less energy use, Tas says the ORCA allows businesses to reduce emissions through a reduced reliance on kerbside waste collection.

“Recycling at the source also means businesses can assist in getting waste trucks off the road, which is a key focus for us.”

Tas says processing 25 tonnes of food waste in the ORCA is the equivalent to reducing the emissions of a diesel truck travelling 21,000 kilometres. He adds that recycling waste at the source also eliminates extra costs associated with bin collection.   

To further minimise the strain of financial output, Tas says iugis put all machines to market as a managed service.

“Investing in new technology can be prohibitive to smaller buisnesses, so we allow users to pay a monthly fee as part of a fully managed service,” he says.

“iugis manages all the consumables including the microorganisms, and offers ongoing preventative maintenance.”

He adds iugis offers a range of ORCAs to suit all size and tonnage needs.

“Our new baby ORCA, which can process 120 kilos of food waste each day, is the perfect solution for smaller businesses such as restaurants, cafés and pubs,” Tas says.

For larger businesses such as hotels and shopping centres, Tas says iugis offers digesters capable of processing up to a tonne of food waste each day.

“The more exposure on-site recycling solutions get, the wider the uptake will be,” he says.

“iugis, which is Latin for perpetuity, is continuously looking to develop technology that increases digestion rates and inspires more on-site recycling.”
