Krones' Fenske notes that beverage manufacturers also are facing the challenge of creating a smaller carbon footprint, and using less water and carbon dioxide (CO2) for carbonated beverages. He also recommends that manufacturers aiming to improve environmental impact invest in newer, volumetric can-filling technology. Krones' Dynafill technology, for example, processes more than 100,000 containers an hour and consumes 20 percent less CO2 in a smaller footprint. The Dynafill features a closed hygienic filling and capping area that eliminates return gas feedback into the product bowl and uses high-pressure injection to ensure product purity and eliminate product loss during filling, Fenske says. "[Krones] currently utilizes low-pressure CO2 can flushing prior to filling, which uses less carbon dioxide," he explains. "To use less water, we capture rinse water for bottles and reuse it for the post-crowner bottle exterior wash-off.
