Touting its vast forests and his administration’s ability to cut through red tape, Gov. Paul LePage pitched Maine as the perfect place for bioenergy executives to make investments. LePage offered his remarks to open the third day of the Advanced Bioeconomy Leadership Conference in San Francisco. The conference, which drew a crowd of more than 300, was convened to bring together investors, reseachers, policy makers, executives and others interested in tapping renewable natural resources for new industrial uses. Maine has more than 17 million acres of forestland, and its economy has been hampered by the closure of five paper mills in three years — mills that used to be a primary market for wood and pulp.
