Since the lock down in Australia forced bars and shops to close down for long, the sale of beer went down.
There were no locals around to enjoy their favorite beverage, thus, the country now has ample storage of beer left behind for use.
The New Source of Energy
The lock-down around the world left in a state of loss. Because there were no bars open for the crowd, Australian brewers are now left with huge inventories of unsold beers.
So much so, that some of the inventory became expired. Rather than wasting it, the state of South Australia came up with a new use of it. They have started using expired drinks for powering water treatment plants!
The Glenelg Wastewater Treatment plant in Adelaide bought millions of liters of unsold beer. It then converted the beer into a renewable source of energy to run its wastewater plant.
The treatment plant uses biogas for running. Industrial waste is mixed with sewage sludge to produce it first and then converted into electricity. The process usually generates enough power to cover 80% of the electricity needs of the plant.
Since the plant started using beer for electricity, it sees a massive boost in production. It has gone up to 654 megawatt hours in a month.
According to Lisa Hannant, the senior manager of production, “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, which is enough to power 1,200 houses,”
A Boost in Electricity Production
According to Hannant, the beer worked great for its plant digesters that create biogas. Digesters are concrete tank with oxygen-free environment where the sludge is heated and decomposed to produce methane gas.
The beer’s high amount of heat that is released during combustion makes the perfect fuel for anaerobic digestion process, as reported by Hannant.
The lock down had an adverse effect on the brewing industry of Austrial. But since Glenelg Wastewater Treatment Plant came up with the idea of using it as a fuel, the brewing industry has new ups to look for.
