Residents at simultaneous town meetings Wednesday evening in Camden and Rockport rejected the recommendations of their town officials and turned down proposals for their communities to contract with ecomaine of Portland for trash disposal.

The two main options for the towns were ecomaine and a proposal by Fiberight LLC, which wants to build a $69 million Hampden facility that would use technology to change organic materials in trash into biogas after the glass, metal, paper and plastic are recycled.

The Municipal Review Committee, which represents towns largely in northern and eastern Maine, has aligned with Maryland-based Fiberight.

In March, the boards of the Mid-Coast Solid Waste Corporation, which serves Camden, Rockport, Lincolnville and Hope, voted to recommend that their communities enter into a contract with ecomaine.

Rockport Town Manager Rick Bates said the voters rejected the ecomaine proposal at Wednesday evening’s Rockport town meeting by a significant margin.

He said the question of what to do next for waste disposal will go back to the Mid-Coast Solid Waste Corporation.

Jim Guerra, executive manager of the solid waste corporation, said the board would meet at 7 p.m. Wednesday, June 22, at the Rockport Town Office. He said ecomaine and Fiberight were the two options and that it would be a matter of the board reconsidering Fiberight or reasserting itself and educating the public on why it backed ecomaine.

Camden Select Board Chair John French told residents at that town meeting that Fiberight had not yet built a plant and that uncertainty was a concern.

Residents at both town meetings, however, said Fiberight’s plan would be less expensive for the towns and more environmentally sound.

Camden and Rockport send their waste to the Penobscot Energy Recovery Company incinerator in Orrington.
