• C. Lee Daigle

  Client Manager

  Lee Daigle is a registered professional engineer in civil engineering with 25 years of experience in the landfill gas industry. Mr. Daigle started his career as an intern at a municipal solid waste landfill in Colonie, New York while attending Rensselaer Polytechnic Institute. While interning, he was fully immersed in the operations, maintenance, and construction of landfill gas collection and control systems, which instilled him with a passion for the industry. Upon graduation, Mr. Daigle continued to focus on landfill gas, and expanded his expertise in landfill gas utilization feasibility assessment, design, regulatory compliance, construction, and operations. Mr. Daigle has worked on landfill gas collection systems in over 30 states/territories, three Canadian provinces, and several countries abroad. He has been responsible for the initial start-up and monitoring of collection and control systems and has performed data analysis and interpretation to assist in optimizing overall landfill gas system performance. He also performed construction management and construction quality assurance (CQA) services during the installation of numerous landfill gas extraction and treatment systems, giving him a strong understanding of the construction issues associated with the implementation of cost-effective landfill gas system designs. Since 2011, Mr. Daigle has expanded his practice into all areas of solid waste design including the design and permitting of municipal solid waste cells and closures. Recently, Mr. Daigle has been elected to the Solid Waste Association of North America's Board of Directors, Wisconsin Badger Chapter and currently serves as Vice President of the board.

  associate professor

  James M. Tinjum, PE, PhD, F.ASCE, is an Associate Professor and outgoing Director of the Geological Engineering Program at the University of Wisconsin–Madison. Dr. Tinjum has 35 years of solid waste experience, beginning in 1990. Prior to his engagement as a faculty member at UW–Madison in 2008, he worked for 15 years in industry for prominent engineer-procure-construct firms and a Fortune 50 company. He has specialized technical knowledge in geoenvironmental and remediation engineering for landfills with industrial waste (lime kiln dust, cement kiln dust, foundry residuals, paper mill sludge, coal combustion residuals), municipal solid waste (particularly landfill liner and cover systems and the monitoring, recovery, and value-added use of landfill gases), and hazardous waste. He conducts research in waste geotechnics and waste containment systems; the beneficial reuse of industrial byproducts (e.g., for subgrade improvement and cementitious stabilization of pavement layers); life cycle environmental analysis of geo systems; remediation of contaminated sites; and fate and transport of landfill gas emissions. Dr. Tinjum developed these interests not only through industry practice and applied research, but also through discussions and interactions with practitioners participating in his nationally/internationally attended engineering short course programs. In applied practice, Dr. Tinjum has participated in nearly 100 solid waste projects.
