Australians consume 69 million litres of beer annually
Australians consume 69 million litres of beer annually, generating an estimated 17 billion discarded bottles and cans each year, theguardian.com reported. Fewer than half of those containers are recycled, and Clean Up Australia ranks drinks containers as the third most littered item nationwide. Commercial brewing operations also drive carbon emissions through production, freight, and resource-heavy agricultural supply chains. In response to this massive footprint, domestic breweries and researchers are testing alternative manufacturing methods, renewable energy systems, and reusable packaging to curb environmental damage.
Corporate breweries target net-zero emissions
Multinational conglomerates control the vast majority of mainstream beer brands in Australia, including Carlton Draught, Victoria Bitter, XXXX, and Tooheys. Japanese parent companies Asahi Group Holdings and Kirin Holdings own these household labels and have established long-term carbon reduction targets. Asahi purchases 100% renewable electricity across its Australian and overseas breweries and offices and aims for net-zero greenhouse gas emissions by 2040. Kirin targets complete renewable electricity sourcing by 2040 and net-zero emissions by 2050. Meanwhile, homegrown craft producers are implementing operational changes faster to shrink their local impact.
Bodriggy pursues carbon neutrality in Melbourne
Bodriggy Brewing Company operates as the second Australian and first Victorian brewery certified as carbon neutral through the federal government’s Climate Active program. Senior brewer Andrew Joseph states that sustainable brewing defines the future of the local industry. The Melbourne business offsets its emissions using carbon credits and targets a further 30-percent reduction by 2030. Bodriggy installed its own grain silo to cut delivery frequency and collaborated with packaging manufacturer Pactec to design reusable keg lids. The brewery plans to adopt e-water cleaning technology and transition to an electric vehicle fleet.
Adelaide University and Coopers trial energy-efficient barley
Researchers at Adelaide University are partnering with Coopers Brewery to investigate barley cultivars that require less energy during the malting process. Malting traditionally relies on gas-powered kilns to dry grain, consuming significant thermal resources. Professor Matthew Tucker, director of the Waite Research Institute, notes that the cheapest energy and the greenest energy is the one that you don’t need to use. Cultivating barley strains that dry faster reduces the energy required for production while lowering operational costs.
Young Henrys turns brewery carbon dioxide into livestock feed
Young Henrys in Newtown generates power using a 30kW solar installation and 100% renewable electricity contracts. The craft brewery collaborates with the University of Technology Sydney to capture carbon dioxide emissions from fermentation and feed the gas into algae bioreactors. The resulting algae is mixed with spent brewing grain to produce a protein-rich animal feed. Trials involving 80 sheep showed promising results, with a testing panel reporting that the algae supplement improved the omega-3 content and flavour of the cooked lamb. Researchers are currently evaluating livestock species to identify options that reduce methane emissions.
Venues across Australia offer refillable glass vessels for takeaway beer
Venues across Australia offer glass vessels known as growlers and squealers for customers purchasing takeaway tap beer. A growler holds 1.89 litres, roughly equivalent to a six-pack, while a squealer provides a smaller 900-millilitre option. Consumers can wash and refill these containers repeatedly at participating locations. Online directories such as Beer Crawl help patrons locate nearby venues offering draft refills.
Frequently asked questions about sustainable brewing in Australia
What percentage of Australian beer bottles and cans are recycled?
Fewer than half of the estimated 17 billion bottles and cans consumed and disposed of annually in Australia are recycled, according to reporting from theguardian.com.
Which major Japanese conglomerates own traditional Australian beer brands?
Asahi Group Holdings owns Carlton Draught, Victoria Bitter, Great Northern, Balter, and Mountain Goat. Kirin Holdings owns XXXX, Tooheys, Hahn, James Boag, Little Creatures, and Stone and Wood.
How does the Young Henrys algae project work?
Researchers at the University of Technology Sydney capture carbon dioxide from Young Henrys fermentation tanks and pump it into algae bioreactors. The harvested algae is combined with spent grain to create protein-rich livestock feed.
What is a beer growler?
A growler is a 1.89-litre glass flask that customers can fill with tap beer at participating venues, then wash and reuse to reduce packaging waste.
