Brewing beer is a complex process that requires careful control of various parameters such as temperature, humidity and carbon dioxide levels. Many breweries strive to maintain optimal CO2 levels, which can affect the quality and taste of their beer.
 
Carbon dioxide is a natural byproduct of the fermentation process in breweries. While it is an important ingredient in beer carbonation, too much carbon dioxide can cause a number of problems:
 
Unsatisfactory flavor and aroma: High carbon dioxide levels can cause a metallic or stale taste, which can harm the flavor and aroma of your beer.
Over carbonation: Excess carbon dioxide can cause over carbonation, resulting in excessive foam and difficulty pouring the beer.
Preventing Spoilage: Controlling carbon dioxide is critical to preventing oxygen from entering the beer, which can cause oxidation and spoilage.
Safety risks: High concentrations of carbon dioxide pose safety risks to brewery workers and can lead to suffocation if not managed.
 
The brewing industry has made significant progress towards sustainability in recent years, with an increasing focus on reducing carbon emissions and managing environmental impact. Among the many challenges faced, a key aspect is the management and control of carbon dioxide (CO2) emissions during the brewing process. Breweries have been employing innovative techniques to reduce their carbon footprint.
 
One of the main ways breweries control CO2 emissions is to capture and reuse the gas produced during fermentation. During the brewing process, yeast converts sugar into alcohol and carbon dioxide. Breweries have implemented specialized systems to capture and reuse this carbon dioxide. Not only does this help reduce emissions, it also allows the brewery to reuse the gas at various stages of production, including carbonated drinks and cleaning equipment. By integrating these closed-loop systems, breweries can reduce CO2 emissions.
