Hillsborough County is leasing its Lithia landfill to Waga Energy to convert landfill gas into renewable natural gas (RNG). The county currently utilizes some landfill gas for operations but burns off a significant amount.

The RNG produced will be sent through pipelines for use as a fuel source in existing natural gas systems, aiming to reduce methane emissions. Critics argue that RNG is a form of greenwashing, as it perpetuates fossil fuel infrastructure rather than promoting truly renewable energy sources like solar.

The U.S. EPA states landfill gas consists of approximately 50% methane, a potent greenhouse gas. Hillsborough's solid waste director recognizes that while natural gas isn't a complete solution, it represents a reduction strategy. The partnership could generate $1 million to $2 million annually for the county over 20 years, depending on the volume of gas processed.
