Tom Cerullo

President
“Leading a unique mix of technology and business development individuals, my job is to help customers gain more value from their processes and products. Notably, our niche is to create value from waste and by-product streams. Sustainability is in our DNA, viewing near-zero waste as a reality within our reach. “While our separation technology is recognized for delivering products of high value in cement, minerals, and protein for humans and animals, entering new markets requires addressing the needs of many stakeholders and achieving buy-in from private and public organizations. This demands a comfort level with the big picture and opening minds to new endeavors. Projects take vision and commitment to bring to fruition, and that’s why our staying power, backed by Titan Cement, an international cement and technology leader, is necessary for continuous success.” Tom Cerullo’s leadership roles at STET began in operations, sales, and business development. At the start of his career, he managed STET’s early commercial installations, the first of which was commissioned in 1995. He has helped drive the growth and evolution of the business from startup to the viable commercial business it is today. Tom is a graduate of the Massachusetts Maritime Academy, which provides a unique education for professionals entering the merchant marine, the military services, and the global marketplace. Before joining STET, he spent more than 4 ½ years as a marine engineer with Military Sealift Command. Adds Tom, “A rigorous academic program, combined with a regimented lifestyle at a young age, gave me a foundation for taking responsibility, having the discipline to endure long-term challenges, and persevering  through complex challenges.”
