Here in Pennsylvania, breweries are at the heart of our communities, bringing people together for a good old bottle of beer. 

However, the truth is that the brewing process is rather a resource-intensive process with a large carbon footprint. 

So in this article, we’ll explore how breweries can adopt greener and more sustainable methods all while maintaining high-quality beer production.

The Environmental Impact of Brewing

A lot of water, energy, and raw materials are involved in the brewing process. For example, a typical craft brewery consumes around 7 gallons of water to produce just 1 gallon of beer. 

That’s in addition to all the electricity needed for heating, cooling, and refrigeration, which emits significant amounts of greenhouse gasses. 

A lot of natural waste is also produced in the form of spent grains, hops, and yeast byproducts—all these must be managed efficiently.

Beyond the actual brewing process, beers are typically packaged in glass bottles or aluminum cans. While these containers are actually easily recyclable, the truth is that most bottles and cans don’t get recycled at all.  

Conserving Water

With the 7:1 ratio of the amount of water needed to the amount of beer produced, breweries consume a lot of water. Here are just some ways they can use water more efficiently. 

1. Water Recycling Systems – Excess water can be used for cleaning and cooling by installing water reclamation systems.
2. Efficient Cleaning Practices – Dry clearing methods (such as using compressed air or vacuum systems) reduce the need to use water for cleaning.
3. Leak Detection and Maintenance – It’s crucial to regularly inspect pipes and other equipment for leaks, as they can lead to tons of wasted water in the long run.
4. Low-Flow Fixtures – Water-efficient faucets and houses can reduce unnecessary water usage, all while not compromising the brewing or clearing process.
5. Smart Water Monitoring – IoT-enabled trackers and other advanced water monitoring systems can help breweries ensure that they don’t use more water than they need. 

Reducing Energy Consumption

Aside from water, brewery equipment demands large amounts of energy, contributing heavily to their carbon footprint. Here are some solutions to make breweries’ energy expenditure more efficient: 

1. Solar and Wind Power – Solar panels are around 20% more energy-efficient, making them a worthwhile investment for long-term sustainability. Wind turbines are another energy-efficient alternative to traditional power. 
2. Energy-Efficient Equipment – Older equipment tends to be less energy-efficient. Upgrading to better, higher-efficiency boilers, pumps, and refrigerators can reduce your overall energy consumption. 
3. Heat Recovery Systems – The brewing process produces a lot of heat—capturing and reusing this head can reduce the need for even more heating. 
4. LED Lighting – Traditional incandescent bulbs consume almost double the amount of energy compared to LED lighting.
5. Smart Energy Monitoring – As with water usage monitoring tech, smart energy usage monitoring systems help breweries use appropriate amounts of energy (and not much more). 

Ingredient Sourcing

How breweries source their raw materials can also play a large role in reducing their carbon footprint. Doing so responsibly and ethically can have a positive impact on the environment.

1. Organic and Locally Sourced Ingredients – By partnering with local farmers for hops, barley, and other ingredients (instead of working with suppliers from more distant locations) reduces transportation needs and their stain on the environment.
2. Regenerative Agriculture – Consider prioritizing working with farms where regenerative farming techniques are practiced. These practices help improve soil health and carbon sequestration.

Managing and Recycling Waste

Managing brewing byproducts effectively is another key component of sustainable brewing. Breweries can implement the following waste reduction strategies:

1. Spent Grain Repurposing – Instead of discarding spent grains, breweries can donate them to local farms for animal feed or use them in baking and composting.
2. Recycling Programs – Establishing comprehensive recycling programs for glass, aluminum, and cardboard minimizes landfill waste.
3. Composting Organic Waste – Composting yeast, hops, and other organic brewing waste reduces landfill contributions and benefits soil health.
4. Eco-Friendly Packaging – Using biodegradable or recyclable packaging materials, such as compostable six-pack rings and lightweight cans, lowers the brewery’s environmental footprint.

Sustainable Transportation

The fuel used in transporting and distributing products also contributes to emissions. Breweries can make their supply chains greener through:

1. Local Distribution Networks – As mentioned, long-distance shipping will naturally consume more fuel, so prioritize local markets and supplies. 
2. Fuel-Efficient Vehicles – Switching to hybrid or electric vehicles for delivery reduces carbon emissions. Studies show that electric vehicles emit 200g of CO₂ per mile compared to the 350g of gasoline vehicles.  
3. Bulk Packaging and Refillable Containers – Offer kegs and growlers to make it easier for buyers to reduce packing waste. 

Engaging Consumers Sustainably

Even in how breweries engage their customers, they can contribute positively to the environment. Here’s how:

1. Digital Marketing and Communication – Instead of relying mainly on printed promotional materials, which produce paper waste, consider transitioning to digital marketing. 
2. Sustainability-Focused Events – Hosting events that promote environmental sustainability (such as tree planting, river cleanups, or eco-friendly beer festivals) can help promote environmental awareness within the community.
3. Incentives for Reusability – Bottle return programs or discounts for customers who bring reusable growlers encourage sustainability within the community at large.
4. Transparency and Certification – Obtaining sustainability certifications such as LEED, B Corp, or USDA Organic is a tangible way breweries can show their commitment to the environment.
5. Energy-efficient Customer Support – For international breweries looking to break into US markets, researching how to get a US phone number for customer service can make communications more sustainable.

Craft Breweries Leading the Way

Several craft breweries are already setting an example in sustainable brewing. Companies such as Sierra Nevada Brewing Co., New Belgium, and Brooklyn Brewery have implemented industry-leading sustainability practices, from using renewable energy to zero-waste initiatives. These breweries serve as inspiration for others looking to make a positive impact on the environment.

Conclusion

While difficult and maybe even costly upfront, investing in more environmentally friendly practices is worthwhile in the long run. 

Doing so can help breweries’ bottom line too. More water and energy-efficient systems can reduce bills. Not to mention, they can draw in more customers—people, after all, are demanding businesses to be more conscious about their environmental impact.

And that’s all while making sure that the next generations can continue to enjoy their company’s beer.
