In and around LaSalle, Heartland Biogas has a rotten reputation. The odorous waste digester and renewable energy producer on Weld County Road 49, southeast of LaSalle, was closed four years ago by the Weld County Board of County Commissioners after repeated odor complaints and other concerns. But new ownership is looking to change the reputation and reinstate the facility's permits. Platte River Biogas, owned by an affiliate of Rockland Capital, has informed the county it intends to apply for reinstatement of the site's use by special review permit. But area residents, the company says, shouldn't be concerned the company is bringing back the noise — or the funk.
