Zero Waste Program Case Study: Spraying Systems Co

Spraying Systems Co. manufactures industrial and agricultural spray products, including spray nozzles and accessories. The company wanted to reduce its waste generation and increase diversion. ISTC's Zero Waste program helped them achieve their goals by providing the company with an accurate baseline measurement of waste generation at its Wheaton, Illinois headquarters. In addition, ISTC staff collaborated with Spray System's operations, manufacturing, and sustainability teams to devise a plan for improving waste diversion. Finally, ISTC staff conducted a post-implementation waste stream characterization to measure success and identify opportunities for improvement.

2015 Illinois Governor's Sustainability Award Winner: Hoffer Plastics, Inc. -Hoffer Plastics used a number of strategies to increase efficiency and reduce their environmental impact. They initiated a 100% facility-wide recycling program that diverted 58,000 pounds of materials from the landfill. Their energy conservation measures reduced their electricity consumption by nearly 4 million kWh. Conservation strategies included: installing high efficiency lighting; replaced chilled water pump motors with variable-frequency drive motors; installed thermal blankets on machine barrels; and implementing a compressed air efficiency initiative. Installing a cooling water filtration system that captures back-flushed water to reuse in the cooling towers has reduced the company's water use by 1.3 million gallons.​
