PORTLAND, Ore. (AP) — Marion County commissioners have given final approval to an order to stop a company from receiving medical waste until procedures are in place to prevent the burning of fetal material to generate power.

While taking the action Thursday, commissioners said they were horrified and disgusted to learn that Covanta Marion was burning abortion waste to generate electricity.

Commissioners Sam Brentano and Janet Carlson made the decision at an emergency hearing. Both strongly oppose abortion rights.

The facility is owned and operated by Covanta in a partnership with the county. It processes 550 tons of municipal solid waste a day, with only a small portion coming from medical sources.

Covanta Marion did not immediately return a phone message seeking comment. The firm did not have a representative at the hearing.
