The Align RNG biogas facility in Turkey, North Carolina, is part of a California-funded initiative to convert hog waste into renewable natural gas (RNG). This project connects 19 hog farms through a 30-mile pipeline to a processing facility.

Local residents have raised alarms about potential pollution and health risks, as the technology may worsen existing environmental issues linked to concentrated animal feeding operations (CAFOs). Environmental justice groups argue that the project's impact disproportionately affects communities of color, as harmful emissions from the biogas process and existing waste lagoons continue to pose risks. The project claims to capture significant methane emissions annually, but local advocates fear it merely shifts pollution rather than alleviating it.
