Industry Insight

Primary Treatment – Flare Stations
Secondary Treatment – Methane Cogeneration
Advanced Treatment – High BTU Cogeneration

– EPA – Environmental Protection Agency – Basic Information about Landfill Gas – (40 CFR Part 98)
– Landfill Gas (LFG) is a natural byproduct of the decomposition of organic material in landfills.
– LFG is composed of 50% methane and 50% CO2
– As of August 2020 – 565 operating LFG energy projects in USA – 475 landfills are good candidates
– When MSW (municipal solid waste) is first deposited in a landfill, it undergoes an aerobic (with oxygen) decomposition stage when little methane is generated. Then, typically within less than 1-year, anaerobic conditions are established and methane-producing bacteria begin to decompose the waste and generate methane.

– LFG is collected through vertical and horizontal piping buried in a MSW landfill.
– Primary Treatment (Moisture Removal) – LFG – Knockout Pot – Filter – Blower – Flare
– Secondary Treatment (Impurity Removal) – After Blower – Siloxane/Sulphur Removal) – Compressor to Boiler to generate steam for Steam Turbine…(CHP) Combined Heat Power – Cogeneration
– Advanced Treatment – After Compressor – CO2 removal N2, O2, VOC removal as necessary – Flare/Thermal Oxidizer for Waste/Tail Gas – High-BTU (Vehicle Fuel or Pipeline Injection)

– 72% of current operational LFG energy projects in USA generate electricity. A variety of technologies, including reciprocating internal combustion engines, turbines, microturbines and fuel cells, can be used to generate electricity for onsite use and/or sale to the grid. The reciprocating engine is the most commonly used conversion technology for LFG electricity applications because of its relatively low cost, high efficiency, and size ranges that complement the gas output of many landfills.

Stalled Pneumatic Pumps

– Minimize the amount of Methane Gas that is released to the atmosphere (help reduce odor & smog)
– Maximize the amount of Methane Gas you can use to fuel the landfill Cogeneration Plant
– QBumpBox and QSolarBumpBox fixes your stalled pneumatic pumps (see brochure)

Stormwater Basins

– Meet CA Regulation for Water Conditioning – Phase II MS4 Permits
– Off-Grid Cloud-Based Stormwater Dosing Skids (see attached article)
– Attached also is California Water Board’s Fact Sheet (other states have similar plans)
