Delta Thermo Energy will be the new owner of Coastal Resources of Maine, the waste-to-biofuel facility in Hampden that has had a dramatic, if short, history since opening in April 2019. The facility closed in May of 2019 and was subsequently placed in receivership. Headquartered in Feasterville-Trevose, Pa., Delta Thermo Energy has a solid track record in waste facilities. The company operates facilities in South Korea, Germany, Japan, Romania, Russia, South Africa and Singapore, as well as piloting programs in the United States.
