WORCESTER, Mass. (AP) — Worcester development officials have approved a plan to build a medical plant-growing facility on a brownfield site in the city. The Planning Board this week gave the go-ahead for PharmaSphere LLC to break ground as the first tenant in the South Worcester Industrial Park. The Telegram & Gazette reports that PharmaSphere intends to build a 50,000-square-foot bioprocessing facility. PharmaSphere will cultivate medicinal plants at the facility for sale as active pharmaceutical ingredients. Earlier this year, the $16.9 million project received a key financing component when the City Council granted a $2.5 million, eight-year loan to PharmaSphere. The project is expected to create about 60 full-time jobs.
