LOUISVILLE, Ky. (WDRB) – A potential biodigester ordinance has cleared a major hurdle.

Louisville Metro's Planning and Zoning Committee passed the proposed ordinance Wednesday evening, but the committee also approved some additional restrictions to the ordinance.

The plant cannot be near the airport, nor can it be within a half mile of any homes or daycares.

Biodigesters break down organic material, such as old food, and turn it into gas.

There were two different proposed biodigesters in Louisville's west end in 2015. But, after neighbors voiced concerns about health hazards and the smell, company organizers back out of the plans.

"Protect our neighborhoods, be conservative with this technology. One mile is still too close. Consign methane plants to the landfill with no waivers," said one resident at Wednesday night's Planning and Zoning Committee meeting.

The biodigester ordinance will now move on to Metro Council.
