The first visible sign of a new Fiberight waste-to-energy plant will get underway soon now that the organization representing more than 100 central Maine communities has voted to release millions of dollars in funding to start constructing a road to the site in Hampden.

The Municipal Review Committee voted unanimously Friday to release up to $1.62 million from the more than $20 million tip fee stabilization fund for construction to start this fall.

Jim Guerra, vice president of the review committee’s board of directors, said he and his colleagues are “relieved and excited” to be moving forward with the project.
