Shawmut Associates LLC has received town approval to redevelop a recycling and solid-waste processing facility on Cranberry Highway. The company, part of New Bedford-based ABC Disposal Service Inc., will dismantle the existing plant and use it at another ABC facility, said Michael Camara, an owner of the family-run business. The new building will be around 89,000 square feet, more than twice the size of the existing structure, and will take in all recyclables, as well as commercial and residential trash, and convert leftovers from the waste process into fuel briquettes that will be sold, Camara said. The plant’s power will come from solar panels on the roof, he said. He added that construction should start in August and be complete a year later, when the company expects to hire about 50 workers.
