Here’s how beer (yes, really) is being used as green energy – Electrek

A wastewater treatment plant west of Adelaide, Australia, is utilizing stale beer to generate biogas, which in turn can power approximately 1,200 homes.

Beer = biogas

Water utility SA Waters Glenelg Wastewater Treatment Plant integrates old beer with sewage sludge. That combination produces a biogas, which is naturally produced from the decay of organic waste that then powers the entire plant. SA Water is owned by the South Australian government and provides services to around 1.5 million people.

So where is SA Water getting the influx of stale beer? From bars, bars, dining establishments, and clubs that have been shut as an outcome of the pandemic, and its putting it to good use.

As Euronews explains:

The plant created a record 355,200 cubic meters of biogas in May and another 320,000 cubic meters in June, according to Energy Live News.

The beer biodegrades under heats in big digester tanks, utilizing natural bacterial processes which release biogas. This biogas, in turn, creates electrical energy.
The wastewater plant has been repurposing 150,000 liters of expired beer each week … As a result, the plant has actually seen eco-friendly energy generation increased to 654 megawatt hours in a single month.

SA Water senior manager Lisa Hannant said:

Glenelgs co-digestion program includes high strength organic waste from industry to sludge from the sewage treatment process.
Utilizing the power of biogas through our onsite gas engines produces sustainable energy for the treatment plant and a sustainable alternative for hazardous waste thats otherwise hard to get rid of and treat.
The industry has actually stayed resilient and adjusted to guarantee their resources arent lost, while enabling a result for the environment.

The wastewater treatment center usually produces sufficient biogas to power around 80% of its energy needs.

Its also a pity for the hospitality and beer industry to be having a hard time like this, however a minimum of the stale beer has been put to good usage. Possibly this design of recycling stale beer for tidy energy is something that can be adjusted for the long term.

The alcohol market has been struck hard by the coronavirus pandemic. Champagne producers have stated theyve lost an estimated EUR1.7 billion ($ 2 billion) in sales this year. There are more than 100 million unsold bottles of fizz. So there is a great opportunity that the grapes may end up as hand sanitizer. (And that is an absolute tragedy, as I am a big Champagne lover, however we do need hand sanitizer, sigh.).
