Landfill gas (LFG) is typically thought of as a byproduct that emerges years after waste placement. But mounting data and operational experience suggest that gas generation begins, and can be collected, much earlier than traditionally assumed. 

This presentation explores a forward-thinking approach to gas collection that challenges conventional timelines and promotes early-stage beneficial use. We’ll first discuss new findings on early LFG generation and explain how collecting gas before regulatory requirements kick in can serve as a best management practice, helping reduce emissions, improve odor control, and support long-term gas management strategies.

However, early gas collection comes with trade-offs. The methane content tends to be lower, and flow rates can be inconsistent. These characteristics make traditional upgrading technologies less effective or economically feasible during the early years. This is where innovation steps in.

We'll introduce a low-pressure cryogenic upgrading system designed to handle the unique characteristics of early-stage gas. Unlike conventional systems, this technology can handle low methane concentrations and variable flow, making it possible to upgrade early-collected gas into pipeline-spec renewable natural gas (RNG). This process can create an earlier revenue stream and help offset the capital cost of gas collection infrastructure.
