World Class Manufacturing
Megatrends across the globe have created a demand for renewably sourced solutions; plant-based alternative products manufactured from renewable resources can have advanced technical properties and functionality compared to their petroleum-based counterparts. For breweries, effective heat transfer is crucial to making refreshing, shelf-stable beverages. Heat transfer fluids are used throughout multiple beverage manufacturing cooling and heating processes. These systems can be found throughout the brewery but are critical in areas such as fermentation and maturation. This study compares traditional petroleum-based heat transfer glycols such as petroleum glycol (1,2-propanediol), used in vessels, jackets, immersion coils, and heat exchangers, with a new plant-based heat transfer material, bio-based 1,3-propanediol. The comparison evaluates safety, stability, pumping efficiency, and a peer-reviewed life cycle assessment. A model system based on a 40,000-gallon fermenter provides insights into where the bio-based propanediol exhibits the optimum performance characteristics across the brewing temperature profile compared to its petroleum-based counterpart. Multiple case studies are presented on the global adoptions the new bio-based glycol highlighting manufacturing performance improvements as well as addressing advances in the sustainable footprint of the sites. The low viscosity profile of the bio-based propanediol enhances pump power consumption, flow rates, and pumping efficiencies, which can improve energy demands and maintenance costs. In addition to being renewably sourced, no petroleum, the bio-based glycol is manufactured using a sustainable process that produces 50% less greenhouse gas emissions and consumes 42% less nonrenewable energy than equivalent petroleum-based diols. At the manufacturing facility’s full capacity, that is equivalent to taking 40,000 passenger cars off the road and turning off one million 100 W incandescent lightbulbs for one full year.
