Landfill Gas Design and Management

Learn about the critical factors of solid waste landfill gas design, management, emissions control, operations, and high-value recovery. The management of LFG emissions and migration control results in positive public image, reduced nuisance odors, protection of public health and safety (i.e., the public good), protection and improvement to the bottom line, and compliance with regulations. Learn from expert and diverse course faculty (top-flight researchers, owners at the cutting edge of evolving practice, industry experts). Get a firm grasp of the background and design specifics to compete in this industry, including industry-leading information on the principles and practices of systems that monitor, collect, transport, treat, and recover landfill gas from municipal, industrial, and hazardous waste landfills. Understand practical emerging technologies and turn your landfill into a revenue-producing, sustainable system for the public good:
