Innovative Brewing: NASA's Wastewater Recycling Revolution
Written on
Chapter 1: Astronauts' Surprising Beverage
Have you ever considered the drinks of astronauts in space? Surprisingly, they consume recycled wastewater, which has been purified using advanced NASA technology. This innovative approach has now been adopted by some breweries on Earth, aiming to address drought conditions and enhance water sustainability.
While this concept might sound unappealing, let's explore why it is a brilliant solution that can benefit both the environment and your palate.
This paragraph will result in an indented block of text, typically used for quoting other text.
Section 1.1: Understanding Recycled Wastewater
Recycled wastewater is not as unclean as one might assume. In fact, it often exceeds the quality of tap water and, according to brewers, has no distinct taste differences. So how does this work? The technology employed by NASA and these breweries is known as reverse osmosis, a process that forces water through a membrane to eliminate contaminants like bacteria, viruses, chemicals, and salts. The end result is pure water that meets or surpasses drinking water standards.
Section 1.2: Addressing Water Scarcity
Using recycled wastewater for brewing is an intelligent strategy to tackle the water shortages impacting many areas, particularly in the western United States. As population growth and climate change increasingly strain freshwater supplies, water reuse can help communities enhance their resilience and lessen their environmental impact. A study from Stanford University indicates that wastewater treated through reverse osmosis can be as clean as, or even cleaner than, groundwater.
Chapter 2: Overcoming Perception Barriers
The first video discusses how a San Francisco brewery uses recycled water in its beer production, aiming to shift public perception regarding wastewater.
One of the challenges to widespread water reuse is the prevalent belief that Canada has an infinite freshwater supply. Additionally, the "yuck factor" plays a significant role: many people struggle with the idea of consuming or cooking with water that has been previously used for showers or toilets. By transforming wastewater into enjoyable products like beer, breweries can help shift this perception and highlight the value of water reuse.
Another pioneer in this field is Half Moon Bay Brewing Company in California, which collaborated with NASA to utilize the same technology that astronauts rely on to recycle their wastewater in space. They crafted a crisp blond ale named Epic OneWater Brew, which resembles a typical craft beer but is made entirely from recycled wastewater.
Brewer Chris Garrett shared with the New York Times his initial skepticism, which vanished after tasting the water and understanding the purification process. He noted that the recycled water was cleaner than the water sourced on-site and had no taste difference. His goal is to raise awareness about water reuse and inspire other breweries to adopt similar practices.
The second video showcases how Village Brewery in Calgary partnered with University of Calgary researchers and Xylem Technologies to brew a blond ale using reused wastewater in 2020. This initiative marked potentially the first instance of direct potable reuse in Canada, where wastewater is treated to drinking water standards without relying on a reservoir or aquifer as a buffer.
The project is part of a larger initiative called Advancing Canadian Wastewater Assets (ACWA), which seeks to develop and test innovative solutions for wastewater treatment and reuse. Researchers aim to showcase the safety and quality of recycled wastewater and to challenge the public's perception of water reuse while adding an element of fun to their scientific endeavors.
Section 2.1: The Taste Test
So, what do these unique beers taste like? According to those who have sampled them, they compare favorably to traditional beers. Some even claim that they are smoother and less bitter. Of course, taste is subjective, and preferences vary, but the reality is that there is nothing inherently unpleasant about enjoying beer made from recycled wastewater. It is safe, clean, and eco-friendly.
In conclusion, this illustrates how technology can be harnessed for positive change and how innovation can address pressing global issues. It also serves as an excellent opportunity to educate people about the advantages of water reuse for both society and the environment. As one researcher stated, "Direct potable reuse is the process of taking wastewater and treating it to drinking water standards without utilizing a reservoir or aquifer as an intermediary. Technologies exist to produce direct potable water from wastewater; astronauts on the International Space Station have been aware of this for two decades."
Next time you encounter a beer crafted from recycled wastewater, don't hesitate to try it. You may be pleasantly surprised by its flavor and the positive impact it represents. Who knows? You might even become an advocate for water reuse and contribute to its growing acceptance.
