Craft brewers cut down carbon dioxide pollution during COVID-19
Share Now on:
Beer makers buy a lot of carbon dioxide. They use it not only to add some fizz to your IPA, but also to purge tanks for cleaning and to transfer beer from tank to bottle.
Most carbon dioxide available for purchase is a byproduct of oil and gas production. But COVID-19 has depressed the price of oil and suffocated the demand for gasoline, so oil, gas and ethanol plants are making less carbon dioxide. Which is making the product more expensive for those who need it, breweries included.
Coincidentally, brewing actually produces a lot of carbon dioxide. But it’s expensive to capture so most brewers just release the gas into the atmosphere, contributing to pollution.
Amy George figured out that it doesn’t have to be that way.
“There are three steps of purification,” she said, pointing to a carbon capture machine at Austin Beerworks, a brewery on the north side of the Texas capital. The machine looks a bit like a hotel ice maker.
“The first are dryers that remove water. The second is an activated carbon vessel that removes impurities, and then the third is a chiller that takes that gas and converts it to a liquid,” George said.
Her company, Earthly Labs, sold this contraption to the brewery about a year ago.
“It was kind of always the holy grail of craft brewing was to be able to figure out how to reclaim the CO2 that we’re producing and be able to put it back into our beer,” said Adam DeBower, one of the co-founders and owners of Austin Beerworks.
DeBower said his company paid about $100,000 for the unit and its installation.
At Denver Beer Company, co-founder Patrick Crawford decided a carbon capture machine made sense there, too.
“I think we’ll see much smaller breweries and breweries our size, capturing their own CO2 and using it,” Crawford said.
One thing that’s driving breweries to capture their own carbon dioxide is that right now some suppliers don’t want to bother with low-volume customers.
“Some of our customers had suppliers say, ‘We’re going to ration CO2 for medical supply use,'” George said. “‘We’re going to increase your prices 30%, we’re going to cut your supply in half.'”
“Everybody’s going to feel the pinch,” said Bob Pease, CEO of the Brewers Association, which represents small and independent American craft brewers. He said a carbon dioxide shortage might get worse before it gets better as bars and restaurants, big users of CO2, reopen.
Molson Coors and AB InBev will likely feel the pinch less so than craft breweries. Because of their scale, larger breweries have been repurposing their carbon dioxide for years.
What’s true for all brewers is that the ability to capture carbon dioxide provides only some of what beer makers need to use, so they currently still have to buy carbon dioxide on the open market.
COVID-19 Economy FAQs
What’s going on with extra COVID-19 unemployment benefits?
It’s been weeks since President Donald Trump signed an executive memorandum that was supposed to get the federal government back into the business of topping up unemployment benefits, to $400 a week. Few states, however, are currently paying even part of the benefit that the president promised. And, it looks like, in most states, the maximum additional benefit unemployment recipients will be able to get is $300.
What’s the latest on evictions?
For millions of Americans, things are looking grim. Unemployment is high, and pandemic eviction moratoriums have expired in states across the country. And as many people already know, eviction is something that can haunt a person’s life for years. For instance, getting evicted can make it hard to rent again. And that can lead to spiraling poverty.
Which retailers are requiring that people wear masks when shopping? And how are they enforcing those rules?
Walmart, Target, Lowe’s, CVS, Home Depot, Costco — they all have policies that say shoppers are required to wear a mask. When an employee confronts a customer who refuses, the interaction can spin out of control, so many of these retailers are telling their workers to not enforce these mandates. But, just having them will actually get more people to wear masks.
