If you’re lucky enough to know someone from Australia you’re probably like “Hold up; Unsold beer…in Australia??”

We know.

But, don’t forget that the country went into full lockdown mode for over 50 days. That means that a lot of the beer sitting in bars, restaurants, and breweries went stale.

Instead of wasting the brew (which would be a bloody tragedy, mate), much of it ended up going to a great cause; powering a water treatment plant.

At the Glenelg Wastewater Treatment Plant, millions of liters of stale beer have been converted into renewable energy in recent months.

The plant uses a mix of organic waste and sewage to create ‘BioGas.’ The gas is used to power the entire facility, providing about 80% of all the energy the plant requires.

But the recent influx of hooch has boosted its energy generation to new levels.

“By adding around 150,000 liters of expired beer per week, we generated a record 355,200 cubic meters of biogas in May and another 320,000 cubic meters in June. Enough to power 1,200 houses,” Lisa Hannant, senior manager of production and treatment at SA Water said in a statement.

Liters and meters aside, the bonus booze has seriously ramped up the power for the treatment plant.

Some breweries are even creating their own biogas on-site, which they can later use to…you guessed it; make more beer. 

One of Australia’s largest brewers, Lion Beer, dumped 90,000 kegs or approximately 4.5 million liters (1.1 million gallons) of beer into onsite biogas containers.

These moves show that there’s nothing less Australian than letting beer go to waste.
