Solid Waste Association of North America (SWANA) books

Prepared by the SWANA Landfill Gas Division, the specifications are representative of today’s construction industry. Organized in three-part format established by the Construction Specifications Institute: General, Products, and Execution. Topics include: Earthwork & Trenching; Condensate Pumps; Pipes, Valves & Fittings; Extraction Wells; Blowers and Flares; Condensate Tanks.

This report compared the output of existing landfill methane models to actual field data obtained from 18 US long-term LFG collection & recovery projects; discusses the advantages & limitations of four types of landfill methane models: a zero-order, simple first order, modified first order & multi-phase first order mode; demonstrates these four models; and provides a computer project titled Methane Gas Recovery Program (MEGAREP) to accept keyboard inputs to project methane generation over time f

This year's symposium covered a variety of topics including: Financing LFG projects anf new market opportunities; A focus on LFG in Florida; The EPA's landfill methane outreach program; Current LFG research and modelig projects; Microturbines; Monitoring LFG area and point source emissions; Combined gas and leachate managment; Outlook for LFG in today's energy market; Siloxanes: analysis and treatment; and LFG collection systems: state-of-the-art and retrofits.

Prepared by SWANA’s LFG Management Division, this document is based on their professional assessment of current practices and procedures for the management of landfill gas systems. The manual covers health and safety, materials, and well installation, with safety procedures stressed throughout.

At the 25th LFG Symposium, sessions focused on the following issues: How are we doing?- U.S. and global data on LFG utilization; LFG markets: old and new!; LFG engines- ask the experts!; Siloxanes and microturbines: operational experiences; Field measurements of emmissions, percent recovery and migration; LFG oxidation: bio-strategies for emissions control; LFG utilization in CA, TN, PA & AZ; Compliance and standards: U.S. and U.K. perspectives; and Innovative strategies: LFG collection, utiliza
