Subijoy Dutta P.E.

Managing Director, S&M Engineering, LLC
Mr. Dutta, a registered professional engineer (P.E.), is fully engaged in water and environmental protection with his leadership in S&M Engineering, LLC (SNM), a Maryland corporation. SNM has a registered office in Kolkata and affiliate offices in Delhi, and Mumbai, India. He finished his B.E. degree in Mechanical Engineering from the Assam Engineering College, Guwahati, India. Mr. Dutta worked in Shillong, India, for about four years before moving to UW-Milwaukee to pursue his MS (Mechanical) degree. A year later, he transferred to the University of Oklahoma (OU) in Norman. After completing two MS degrees, one in Mechanical and the other in Petroleum & Geological Engineering from the OU, Mr. Dutta joined OU as a research faculty and opened his own consulting company, S&M Engineering Services. Later he joined the Tinker Air Force Base in Oklahoma City, where he arranged to clean up five waste sites within a very short time. This earned him a National Award for Environmental Excellence in 1992 from the Air Force Chief of Staff in Washington, DC. Later, Mr. Dutta joined the US Environmental Protection Agency in DC and worked there for 20 years. During that time he worked with a multi-discipline team involving various EPA regional offices and industries to develop the best management practices guide for treatment technologies to minimize emissions and migration of contaminants. He also provided active support to help the Central Pollution Control Board in India in their development of regulations for municipal solid waste management and medical waste. Mr. Dutta’s 35-plus years’ experience as an environmental professional spanned across protection and restoration of human health and the environment involving municipal, hazardous and medical waste sites management. His work in protecting the human health and the environment covers the Yamuna River basin in India, Iloilo River in Philippines, Bagmati River in Nepal, and the Yangtze river in China. Mr. Dutta conducted a number of national and international environmental assessments, remedial design and a few site cleanups. He provided training seminars in medical waste management in cities/universities in India and US. Mr. Dutta visited medical facilities in India and provided training to the hospital management and staff in safe management of infectious waste and the effectiveness of Segregation at source. He provided training seminars in medical waste management in cities/universities in India and
the US.

Mr. Dutta formed the Rivers of the World Foundation, a charitable organization. He is actively working on over 10 rivers in India, Philippines, Nepal, China, and Indonesia. He has authored the following two books: Environmental Treatment Technologies for Municipal, Industrial and Medical Wastes Remedial Scope and Efficacy, 2nd edition, Taylor & Francis (CRC Press), and Sustainable Mining Practices – A Global Perspective, published by Balkema Publishers.
