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.

Sacyr opens waste treatment plant in south-east Melbourne

International waste management company Sacyr has opened a waste treatment plant in Melbourne with the capacity to process 120,000 tonnes of organic waste per year.

A Sacyr spokesperson said the indoor composting facility will be one of the most advanced of its type in Victoria.

“The facility will be used by councils in the south eastern suburbs of Melbourne, providing service to a population of 1.2 million people to recycle green garden and food waste,” the spokesperson said.

“The resulting compost will have a great commercial value due to the aerobic tunnel fermentation process and the aerobic maturation in the warehouse, resulting in a product that complies with the most demanding standards within the industry and with the rigorous Australian quality standard AS4454.”

According to the spokesperson, the facility takes the process of composting and industrialises it.

“Instead of relying on individuals to compost their organic waste, Sacyr can compost the organic waste of eight south-east Melbourne metropolitan councils and produce up to 50,000 tonnes of quality compost per annum.” the spokesperson said.

“The facility creates several environmental benefits to the Australian waste management sector such as reducing the amount of landfill waste and reducing the emission of greenhouse gasses such as methane.”

The spokesperson said all plant warehouses will be completely sealed and have an efficient deodorisation system so not to affect neighbouring residents.

“With the start-up of the plant, more than 65,000 tons of CO2 per year will cease to be released into the atmosphere and the emissions generated by landfill waste will be reduced by 85 per cent, the equivalent of removing 13,900 cars from circulation,” the spokesperson said.

The facilities treatment process combines a mechanical system developed by German company Stadler and a biological and air treatment system designed by Dutch company Waste Treatment Technologies.

“Sacyr’s know how, acquired over more than 20 years, will be an innovation in Australia’s current waste management system,” the spokesperson said.

“This procedure stands out, among other aspects, for its ventilation spigots and leachate collection systems.”

Geelong launches $3M organics composting facility

The City of Greater Geelong has launched a $3 million garden organics composting facility that is able to recover 35,000 tonnes of green organics per year.

Compost from the Geelong Garden Organics Composting Facility will be used on council land, such as parks and ovals, and local farmers. It will see an abatement of 49,000 tonnes of carbon dioxide emissions per year.

Sustainability Victoria provided a $500,000 grant towards the facility on behalf of the Victorian Government.

Projects in regional Victoria have increased the organics processing capacity by 38,250 tonnes per year, with approximately 74,570 households now able to access kerbside collections for food and/or organic waste. With the launch of the new facility, kerbside organics collection services have resulted in an average abatement of 81,621 tonnes of carbon dioxide per year.

Sustainability Victoria CEO Stan Krpan said he was delighted to see the organics facility opened.

“We’ve been working closely with the City of Geelong to enable greater recovery of its valuable resources,” he said.

“Victoria’s population could reach 10 million by 2050, putting pressure to our waste recovery and disposal systems. Taking action now through creating and expanding recycling opportunities will greatly reduce the environmental impact of these resources ending up in landfill, and their economic value being lost.

“This project falls under Statewide Waste and Resource Recovery Infrastructure Plan and the Victorian Organics Recovery Strategy, which plans for all viable recovered materials to be extracted from waste streams before reaching landfill,” Mr Krpan said.

The new Geelong facility is able to provide long term benefits such as processing the council’s green organics, with the potential to process additional organic materials such as food.

“Geelong is one of three large regional organics projects funded by the Victorian Government. It followed Ballarat and Bendigo which all now divert large quantities of organics from waste streams,” Mr Krpan said.

EPA VIC consider application for $12M waste to energy facility

Resource Resolution Pty Ltd has applied to establish a $12 million commercial food waste processing facility which has the capability of producing biogas for energy.

The proposed facility would process 30,000 tonnes of liquid food waste a year and produce 2.4 megawatts of power.

Resource Resolution also aims to recover organic matter for use as animal feed or to generate renewable energy with an anaerobic digestion facility.

Environment Protection Authority (EPA) Victoria received the works approval for the site, planned to be located at 19 Winter Road, Girgarre.

Resource Resolution has proposed to use the Biogass Renewables AD system, which is currently used in Perth, WA. It is estimated that the bioenergy operation will process 23,382 tonnes of dairy, 3,475 tonnes of food products, 2,421 tonnes of fruit and vegetables and 722 tonnes of supermarket and grocery waste.

EPA Victoria’s assessment of the application will consider best practice technology, energy efficiency, greenhouse gas emissions and waste composition. It will also assess any potential risk to human health and the environment, including from emissions to air, noise, disposal of digestate, the waste water treatment system and operation contingencies.

An application for an amendment to the current planning permit is currently under assessment by Campaspe Shire Council.

Works approvals are required for industrial and waste management activities that have the potential for significant environmental impact.

CEFC finance composting facility for Melbourne councils

Organic waste from eight Melbourne councils will be sent to a new composting facility, to be built by international waste management company Sacyr Group.

The Clean Energy Finance Corporation (CEFC) will commit up to $35 million towards the new composting facility.

Related stories:

The $65 million South Eastern Organics Processing Facility will be the most advanced of its type in Victoria and will produce approximately 50,000 tonnes of high grade compost each year.

The compost will be made from processed household garden and food waste from council kerbside green waste collections in Melbourne’s south-east, which will then be used on local parks and gardens.

Food and green waste makes up an estimated 42 per cent of landfill for Australia’s municipal and commercial waste streams.

The Melbourne councils include Bayside, Cardinia, Casey, Frankston, Glen Eira, Greater Dandenong, Kingston and Monash.

Sacyr expects the fully-enclosed, in-vessel aerobic composting and maturation plant will be operational by mid-2019. It will aim to operate for 15 years, with a potential five-year extension.

The new facility will have an annual processing capacity of 120,000 tonnes of waste each year, the equivalent of 12,000 truckloads of waste. It is expected to abate more than 65,000 tonnes of carbon dioxide equivalent emissions annually. This would cut the greenhouse gas emissions from landfill by 85 per cent if it were to be landfilled, which is equivalent to taking 13,900 cars off the road.

Sacyr Group has built 48 plants around the world and handles more than three million tonnes of waste each year. It currently operates in Australia through its subsidiary, Sacyr Water, which has built and operates the Binningup desalination plant.

The technology used in the plant has been developed over two decades, ensures plant storage reservoirs are completely closed, and uses efficient and reliable deodorisation systems.

Federal Government  Environment Minister Josh Frydenberg said converting waste to compost can play a part in Australia’s long-term waste solutions.

“This facility alone, which will be the most advanced of its type in Victoria, can process around 12,000 truckloads of waste per year,” Mr Frydenberg said.

“It means food and organic waste produced by south east Melbourne residents will not end up in landfill and will instead produce high-grade compost for our gardens and parks.”

CEFC CEO Ian Learmonth said the corporation is looking across the economy to identify finance opportunities to reduce Australia’s emissions.

“We’re pleased to be making our first project investment to help councils and communities tackle emissions from their organic waste,” he said.

“When organic waste such as food and green waste ends up in landfill it breaks down and produces methane. With this technology, councils can avoid those emissions by turning their organic waste into reusable compost, while also reducing our unsustainable reliance on landfill as a waste disposal option.

“We strongly endorse the principle of avoiding and reducing waste at the source. Our finance is about effectively manage the remaining waste, so that it doesn’t end up as landfill and we make a meaningful difference to our greenhouse gas emissions,” Mr Learmonth said.

CEFC Bioenergy Sector lead Henry Anning said the CEFC finance model for the Melbourne project was an industry first, providing councils with access to a project financing structure that has rarely been leveraged across local government.

“Australia’s waste sector is facing enormous challenges, because of the growing amount of waste we produce as well as increasing community concerns about the way we handle that waste. This new Melbourne facility provides us with a practical and proven way to turn organic waste into a reusable commodity at the same time as avoiding harmful emissions,” Mr Anning said.

“We expect to see more councils and communities consider innovative ways to manage all forms of waste. This innovative project finance model offers opportunities for other groups of councils considering investing in substantial waste management infrastructure to reduce landfill waste.”

Monash Uni helping farmers profit from food waste

Research has begun on helping farmers transform their food waste into profit while improving their business model thanks to a joint effort from Monash University’s School of Chemistry, IITB (India), the Food Innovation Centre and the agriculture industry.

Monash University is using a holistic approach to ‘biomass valorisation’ to help the industry extract high value components such as antioxidants, oils, pectin and protein from food disposal. Mangoes, pomegranate and pineapple skin, spent coffee grounds and almond ash.

The food waste also extends to fresh produce that is disposed for not meeting the cosmetic standards of supermarkets.

Professor Tony Patti said the biomass valorisation looks at the entire fruit or vegetable, not just what is eaten, which is what currently provides value to the grower.

“The skins, seeds, kernels, leaves and off-cuts were seen as ‘waste’, adding to their disposal costs. These by-products are not waste, but a potential valuable resource, providing several components, identified as being of high market value,” Dr Patti said.

“Monash is working with Australian growers and businesses to diversify the potential market opportunities, including expansion into the pharmaceutical, cosmetic and pet food industries.

“Using this research, food and agricultural companies can tackle costly waste challenges, improve their environmental footprint and create a sustainable business that takes full advantage of growing demand in domestic and export markets for high quality food products,” he said.

Half a million dollars awarded to Vic regional composting facility

A proposal to develop a regional Victorian composting facility has received $500,000 in funding from the state government.

Organic waste management company Pinegro are developing a $5 million project to use an enclosed tunnel system for the composting of food and organic green waste from local councils in the Morwell region.

Related stories:

Currently, Pinegro composts using an open windrow method but this process can be affected by weather conditions.

By implementing the new system, the company will be able to compost within a contained, temperature-controlled environment to deliver a better product, faster.

Pinegro’s grant will go toward the construction of a waste receival building, composting tunnels and air and water filtration systems.

It is expected to divert 18,000 tonnes of organic waste from landfill each year.

The funding was part of the second round of the Resource Recovery Infrastructure Fund, which is supporting 13 projects across regional Victoria.

These projects are expected to divert more than 85,000 tonnes of waste a year from landfills.

Victorian Minister for Environment Lily D’Ambrosio said food waste from homes accounts for around 250,000 tonnes a year in Victoria.

“These upgrades to the composting system will increase Pinegro’s capacity to process food waste and absorb more from local councils,” she said.

Applications for the third round of the Resource Recovery Infrastructure Fund are now open. For more information, click here.
