At Pack Expo, materials were not the only products showcasing green innovation. At the Ossid booth, the company displayed a new low-cost water recirculation system for its case-ready tray overwrapper that can conserve an average of 375,000 gal of water per year. The recirculation system can be ordered with new overwrappers or can be individually retrofitted to existing ones.
"For years, Ossid overwrappers helped improve the sustainability of a packaging line by minimizing consumption of shrink film," says Ernie Newell, vice president and general manager of Ossid, a division of ProMach. "The new water recirculation system contributes to greater sustainability by significantly reducing the water footprint of the packaging line."
Newell explains that Ossid case-ready tray overwrappers are cooled by circulating about 1.5 gal of water/min through the machine. At that rate, each overwrapper consumes about 720 gal of cooling water per eight-hour shift. During a 52-week period, for example, the total water consumption would be slightly more than 375,000 gal. According to Ossid, plants running multiple overwrappers during multiple shifts can easily save the cost of millions of gallons of water entering and leaving the plant.
Following an 18-month research and development effort, Ossid developed a low-cost water recirculation system that when added to an overwrapper cools the machine with as little as one gallon of water per day. The new recirculation system automatically replenishes evaporated water as needed and requires minimal maintenance. Newell estimates the system will pay for itself in less than a year.
