Blog: Why Tankbeer Systems Are the Sustainable Choice for Breweries

As the brewing industry continues its journey toward greener practices, the spotlight is increasingly on smarter logistics and sustainable packaging.

At Duotank, we understand the urgency for breweries to reduce their environmental footprint—without compromising on quality or efficiency. One innovation that’s making a meaningful difference? Tankbeer systems.

In this blog, we explore how tankbeer offers a more sustainable approach across production, transportation, usage, and cleaning—helping breweries move toward a more eco-conscious future.

Sustainable Production: Reusable Tanks, Recyclable Materials

Tankbeer systems significantly lower their environmental impact compared to traditional beer logistics. The tanks are made of high-grade stainless steel, a durable material that can be reused for decades and is almost entirely recyclable—often already containing recycled content when produced.

The only single-use component in the system is the inliner—a food-grade plastic bag that holds the beer inside the tank. While once considered a weak point in terms of sustainability, today’s inliners are increasingly made from fully recyclable materials, marking a big step forward in reducing waste and enhancing the system’s eco-friendliness.

Smarter Logistics: No Empty Returns, Less Fuel Use

When it comes to transport, tankbeer also shines. Unlike kegs, there’s no need to return empties—reducing round-trip shipping. As the tank empties during delivery, the total vehicle weight decreases, cutting down fuel consumption and emissions throughout the delivery cycle. It’s a win for efficiency and the environment.

Eco-Friendly in Use: Less CO₂, No Wastewater

Perhaps the biggest sustainability win is seen during the usage phase. Traditional keg systems rely on CO₂ to push beer out of the container, but tankbeer systems use compressed air instead.

Let’s compare:

  • Tapping 50L of beer from a keg uses approximately 6 kg of CO₂.
  • Tapping the same amount from a tankbeer system uses only 3 kg of CO₂, through compressed air production.

That’s a staggering difference in carbon emissions.

Easy, Water-Free Cleaning

Once the tank is empty, there’s no need for a deep clean. The process is as simple as removing the used inliner and replacing it with a new one. This eliminates the need for water, chemicals, and energy-intensive cleaning cycles—a major contrast to the extensive cleaning required for reusable kegs and bottles.

The Bottom Line: Better Beer, Lower Footprint
Tankbeer systems offer breweries a smarter, cleaner, and greener way to distribute their product. From production to pour, the environmental benefits are clear—and growing with every innovation.
