GOING GREEN: CAN WE BE SUSTAINABLE FOR TOMORROW WITHOUT SACRIFICING TODAY?

**A Testing Laboratory Case Study** Some companies go beyond legal requirements to meet or exceed compliance targets, showing their commitment to sustainability. By proactively investing in environmental measures, they not only reduce risks like fines and legal issues but also often improve their bottom line. One automotive R&D lab found a sustainable solution that saved money right away, reduced long-term costs, and solved multiple chemical handling challenges. Intertek is a top provider of third-party testing and research services for the global R&D industry. Their Automotive Research Lab in San Antonio, Texas, is one of the largest independent facilities in the U.S., offering engine, transmission, emission, and fluid testing services. As part of their strict testing procedures, Intertek builds engines according to ASTM standards to ensure precise testing under controlled conditions. Before assembly, each engine part is measured and weighed. After testing, the process is repeated to evaluate changes in the components, which helps assess fluid performance. To accurately weigh and inspect parts, each component must be thoroughly cleaned using solvents like N-pentane, N-hexane, Toluene, Tri-solv, and Acetone. For Intertek’s team, handling drums of chemicals was time-consuming and frustrating. Technicians had to tip 55-gallon drums onto their sides to dispense solvents, then return them upright after use. This process involved threading brass fixtures, managing vents, and dealing with gravity-fed spigots—leading to leaks, clogs, and spills. It was also difficult to completely empty the drums, resulting in wasted chemicals and extra labor to meet EPA regulations. Bob Tome, Intertek’s Manager of ES&H, was looking for a better solution. He attended an industry seminar by TCEQ’s Pollution Prevention Group and discovered an environmentally compliant pumping system. Surprisingly, it cost less than the current spigots and was more durable. The new system allowed staff to safely dispense chemicals directly from upright drums at four gallons per minute, improving efficiency and safety while eliminating dangerous tipping and spills. With the pumps in place, the cleaning process became easier. Chemicals could be transferred directly into smaller lab containers and dispensed via spring-activated nozzles. The system also enabled full drainage of drums to within half an inch, meeting RCRA standards and saving on disposal costs. Pumps lasted up to ten years, reducing waste and maintenance needs. “I’m really impressed with the savings,” said Tome. “The pump cost about $300 less than a spigot, and it lasts ten years instead of needing frequent replacements. Over time, these savings add up. Plus, we improved safety, reduced waste, and achieved our sustainability goals.”
