Environmental Integrity Project says Maryland is quickly becoming the nation's capital for waste-to-energy plants which, it says, are more polluting than coal-fired plants.
The Washington-based environmental group says Maryland has three waste-to-energy plants permitted or under development and two already in operation. It's data shows the state's two largest incinerators create more pollution per hour of energy generation than each of the state's four largest coal-fired plants.
Environmental groups earlier this year criticized a decision by Gov. Martin O'Malley to support enhanced incentives for waste-to-energy. They say it will hurt recycling efforts.
