Perth based Biogas Renewables has commissioned a plant that will take between 35,000 and 50,000 tonnes of food waste per year and is capable of producing between 2.4 to 2.6 megawatts of energy.

The company was awarded the Large Scale Bioenergy Innovation Award for the project, with Bioenergy Australia CEO Shahana McKenzie saying the application of anaerobic digestion is a major advancement of the Australian market.

Biotechnology company Microbiogen was awarded a commendation for its development and launch of a superior biocatalyst for the global bio-ethanol industry.

Ms Palaszczuk was awarded the Government Leadership Award for the Queensland Government’s 10-year Roadmap and Action Plan to support the growth of the state’s bio-economy. The plan identifies 15 current projects which represents a potential investment of around 41.4 billion and the creation of 2500 new jobs in rural and regional communities.

“The integrated approach is paving the way for Australia to develop a sustainable, export-oriented industrial biotechnology and bioproducts sector by 2026,” Ms McKenzie said.

“The plan shows a pathway which recognises Queensland’s mix of natural resources, skilled workforces, world-class research and development and supporting supply chain industries.”

The research Leadership Award was presented to the Australian Biomass for Bioenergy Assessment platform, which is a collaboration of states, industry and universities to enable better links between biomass suppliers and end users.

Victorian Pyrenees Shire Council won the Community Leadership Award for its large-scale project which focused on converting straw and straw pellets to energy.

Ms McKenzie said the awards are recognition for the breadth and scope of the bioenergy work being undertaken across Australia.

“Bioenergy is the subject of considerable interest and investment world-wide, due to its enormous potential to reduce carbon emissions and drive a more sustainable energy future,” she said.

Consortium to harness value from agricultural waste

A new $10.9 million research consortium is set to increase the value of agricultural waste by turning it into new products, led by the University of Adelaide.

A total of 18 partners will come together to develop high-value products from agricultural waste, including nine South Australian based companies from the agriculture and food sector alongside nine national and international academic institutions and industry partners.

The Agricultural Product Development Research Consortium has been granted $4 million over four years by the South Australian Government, with the University of Adelaide contributing $2.3 million, with the remaining support coming from partners.

Biomolecules that can be derived from crop waste show potential anti-oxidant, anti-inflammatory, anti-microbial, anti-cancer or gut health properties. Other uses include providing mechanical strength or texturizing properties in food, structural materials, lubricants and cosmetics.

Waste from apples, cherries and mushrooms could be used in skin care products thanks to their biological makeup while waste from broccoli, cauliflower, brussel sprouts or cabbage could have potential benefits for diabetic patients.

Research Consortium Lead Investigator and Director of Adelaide Glycomics Professor Vincent Bulone said Agriculture is a key contributor to SA’s economy which has a potential to generate high value products and create post-farm gate industries.

“Our agricultural and horticultural industries generate abundant waste biomass, which is currently disposed of at a cost to the producer, or only a low return. But there are compounds we can derive from this waste – a range of different ‘biomolecules’ – that have high-value potential applications for their structural or health properties,” he said.

Some consortium partners include CSIRO, University of South Australia, KTH Royal Institute of Technology (Sweden), Coopers Brewery, Carlsberg Group (Denmark), Raw Nation Wholefoods, Vanquish Technologies and Ingredion Inc (USA).

SA Minister for Industry and Skills David Pisoni said South Australia’s agricultural sector is a significant contributor to the growth of the state’s economy.

“The outcomes from this major research consortia that includes local, national and international research institutions along with industry partners, will contribute to the creation of new post-farmgate industries through the development and commercialisation of value-added products from agricultural waste,” he said.

Byron Bay Bioenergy calls for businesses to help supply feedstock

Byron Shire Council, NSW, has opened an expression of interest for the supply of commercial organic waste to the proposed Bioenergy Plant in Byron Bay.

The technology involved in the waste to energy plant is able to receive more than what the Byron Shire Council already collects, meaning more can be contributed from additional sources.

Byron Shire Mayor Simon Richardson said they’re putting out the call to local business and industry to supply commercial food waste and commercial fats, oils and greases as feedstock for the bioenergy plant.

“This is a huge win for our community because it will enable businesses to divert large quantities of commercial food waste from landfill to a Council owned and operated 400-kilowatt bioenergy plant to power our Sewage Treatment Plants,” Cr Richardson said.

“It is the start of us creating our own clean and renewable energy here in the Byron Shire and I strongly encourage our business community to get on board this ground-breaking initiative.

“Our intention from the start was to create a local and scalable bioenergy solution and it is very exciting to be at the stage where we are here inviting the business community to the table,” he said.

It is proposed that the new Bioenergy plant will be located at the Byron Sewer Treatment Plant sit on Wallum Road, Byron Bay.

The Bioenergy plant will help Council reach its zero emissions target by 2025 and make some serious reductions to our carbon footprint,” Cr Richardson said.

It is expected the plant will be commissioned and operational by December 2020.

New solar powered composter for Canberra community

A new solar powered composter has been unveiled at the Canberra Environment Centre to launch the Canberra Community Composting project.

The composter was purchased by the centre after it received a $24,200 grant from the ACT Government’s Community Zero-Emissions Grants program.

Food scraps can be dropped off at the Environment Centre to be processed by the new machine, nicknamed The Hungry Composter. The project aims to support members of the community who feel as if they don’t have the time, space or knowledge to compost at home.

The Hungry Composter is able to process 100 litres of mixed waste a day, including paper, cardboard, food scraps and green waste. It is solar power, odourless, continuous-feed system that processes food scraps into ready-to-use compost within 10-14 days.

Community members need to register with the Environment Centre before disposing of their waste for composting.

ACT Government Sustainability Programs Senior Manager, Ros Malouf said it was a fantastic example of a community group working with the ACT government to implement a project which will have significant benefits for both residents and the environment.

“In addition to generating nutrient rich soil, composting is a great way to reduce emissions. Organic material sent to landfill produces methane, a greenhouse gas that is approximately 25 times more potent than carbon dioxide.”

Turning waste into water in the City of Melbourne

More than 60 tonnes of waste have been diverted from landfill thanks to a machine installed by the City of Melbourne that turns food scraps into waste water.

Over the last year, the ORCA aerobic digestion system has used micro-organisms to transform 62 tonnes of food scraps from the busy Degraves street face precinct into greywater, making it one of the most heavily used machines of its type in Australia.

ORCA Enviro Systems Executive General Manager Tas Papas said micro-organisms in the unit digest the waste, creating wastewater that goes straight into the sewer system via a grease arrestor.

The ORCA is basically a mechanical “stomach” that digests fruit, vegetables, grains, dairy and proteins, so you end up with greywater that is safe to put into the drain without resorting to landfill,” Mr Papas said.

“Degraves Street cafes set aside food waste as part of their daily operations. By diverting the food waste from landfill, we are also able to prevent greenhouse gases from escaping into the environment.

“Over the course of a year, that also means more than 8,000 litres in diesel fuel is saved because fewer trucks are needed on the road.”

Because space is a premium in the city centre, ORCA was chosen to handle the increased volume of food waste being generated from the busy café district.

“The ORCA has helped City of Melbourne to build strong support among local businesses for food recycling efforts and keep the bustling precinct clean and appealing,” Mr Papas said.

The machine was installed in the Degraves Street recycling Facility in May 2017. The ORCA is rolling out across Australia in pubs, shopping centres, food courts and hotels.

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.

Related stories:

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.”

Planet Ark partner with Bingo Industries to divert coffee grounds

A new trial aims to divert spent coffee grounds from landfill and repurpose them into higher value uses.

Planet Ark will begin the Coffee 4 Planet Ark trial in September in Sydney, in collaboration Bingo industries and with leading coffee roasters and members, such as Lavazza. Tata Global Beverages via its Map Coffee brand will collect spent coffee grounds from limited corporate businesses in Melbourne.

The program aims to roll out around the country in 2019 after it identifies the best and most cost-effective collection method.

Planet Ark undertook a 2016 feasibility study that found almost 2800 tonnes of spent coffee grounds are sent to landfill in Sydney alone.

Once in landfill, the grounds would begin to break down and produce methane. Diverting the spent grounds from Sydney would save approximately 1600 tonnes of carbon dioxide equivalent emissions annually, according to the study.

To develop new end uses for coffee grounds, Planet Ark has begun working with the SMaRT centre at the University of New South Wales. It has also secured a partnership with Circular Food to produce a nutrient rich soil fertiliser called Big Bio, which will utilise the collected grounds.

Planet Ark CEO Paul Klymenko said the Coffee 4 Planet Ark program was an important step in ensuring spent coffee grounds were being used to their greatest potential rather than entering landfill.

‘Currently, the vast majority of coffee grounds produced after extracting your coffee are going to landfill. Planet Ark believes in creating a circular economy where all resources are used to their greatest potential,’ Mr Klymenko said.

‘We are thrilled to be working with some of Australia’s leading coffee roasters to trial a collection and repurposing system for coffee ground waste.’

REMONDIS and Lake Macquarie open new organics processing facility

REMONDIS Australia and Lake Macquarie City Council have opened a new organics processing facility at the Awaba Waste Management Facility.

REMONDIS Australia and Lake Macquarie City Council have opened a new organics processing facility at the Awaba Waste Management Facility in late July.

It is part of the council’s new three-bin waste management system, which aims to reduce the amount of waste sent to landfill by as much as one third by recycling food refuse.

Food and green waste will be recycled at the new facility and turned into compost products for reuse on parks, grounds and sporting fields.

The facility has a unique hybrid model of ‘in-vessel’ and ‘mobile aerated floor’ systems and includes a fully automated tunnel composting system to pasteurise food waste in two weeks

With a mobile aerated floor finishing. It also includes an automatic, cashless weighbridge system that gives users access to the facility with the swipe of a card.

REMONDIS CEO Luke Agati said the company is proud to be investing in Lake Macquarie and the Australian resource recovery sector.

“REMONDIS has been composting garden waste at Awaba for Lake Macquarie City Council since 2013, and this new facility will enable us to also convert food waste into a valuable resource,” Mr Agati said.

“The facility will convert up to 44,000 tonnes per year of organic waste into compost and soil amendment products.

“REMONDIS applauds forward-thinking local government organisations such as Lake Macquarie City Council for their dedication to building the vital recycling infrastructure that will create job opportunities, strengthen the Australian economy and reduce our environmental footprint.”

Lake Macquarie Mayor Kay Fraser said the Organics Resource Recovery Facility would see the City take a leading role in recycling and waste management.

“This is a significant step in our Waste Strategy and in our efforts to encourage people to think and act more responsibly about household waste disposal,” Cr Fraser said.

“By making it easy for residents to dispose of organic waste appropriately, we will encourage them to recycle and close the food consumption loop.

“About one third of household garbage bin contents is food waste, so this will divert significant amounts of organic material from landfill, extending the life of our Awaba Waste Management Facility and saving an estimated $4 million over 10 years in waste management costs.”

The project was supported by a grant of $2 million as part of the NSW EPA’s Waste Less, Recycled More initiative, funded from the waste levy.

Parliamentary Secretary for the Hunter Scot MacDonald said the NSW Government was pleased to assist by contributing a $1.4 million grant to the facility and $0.6m for community engagement initiatives, from the EPA’s Waste Less Recycle More initiative.

“This facility will improve the availability of organic compost for local primary producers and reduce unnecessary wastage of high quality organic material. I congratulate Lake Macquarie City Council in securing investment from a business with the calibre of REMONDIS.”

More than 100 contracting firms were engaged to build the facility, which also features an education centre where schools and community groups can see the recycling process.

Lake Macquarie Organics Resource Recovery Facility Branch Manager Gunther Neumann said REMONDIS is proud of its environmental achievements in Lake Macquarie.

“Since 2013, REMONDIS has diverted more than 100,000 tonnes of garden organics from landfill in the region, saving more than $13 million in landfill levies for residents,” Mr Neumann said.

“With the opening of the Lake Macquarie Organics Resource Recovery Facility, REMONDIS looks forward to a new chapter in organics processing that will deliver additional landfill levy savings and create new market opportunities locally, reinforcing our role as a valued member of the local community.”
