Regardless of fuel prices, energy efficiency is a top-of-mind consideration for most manufacturers these days. One Fortune 500 company in the food packaging industry achieved notable energy-efficiency improvements with an uncommon green initiative that combines pollution-control systems with process heating equipment.
The company produces resealable aluminum bottles for beverages. Because these containers come in direct contact with the consumable liquids, they must be washed and internally coated to ensure safety and product quality. Once applied, the inside coating is heated in an oven for curing. The entire process is energy intensive, requiring both hot water for washing the cans and hot air for drying the coating. In addition, harmful emissions are generated from the coatings as they dry.
