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.”

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.

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.”
