MaineHealth Pen Bay Hospital and MaineHealth Waldo Hospital are advancing sustainability initiatives aimed at reducing waste and lowering greenhouse gas emissions. These efforts are part of MaineHealth’s broader environmental responsibility strategy, which focuses on minimizing the health system’s environmental footprint while maintaining high standards of patient care.

A big component of this work is food waste reduction. Though a composting program launched in 2024, the hospitals significantly increased the amount of food diverted from landfills. Composting volumes rose from around 15,000 pounds to more than 41,000 pounds within a year, demonstrating measurable progress in waste diversion. This initiative helps decrease methane emissions associated with landfill disposal while promoting more responsible materials management.

The hospitals have also implemented operational changes within their cafeterias. By shortening menu cycles, food production can be better aligned with actual demand, reducing overproduction and unnecessary  waste. These adjustments allow staff to more accurately track food usage and purchasing patterns. Also, surplus food than remains safe for consumption is donated to local community organizations, including AIO Food and Energy Assistance and the Belfast Soup Kitchen, supporting food security efforts.

Beyond food-focused strategies, both hospitals have completed energy conservation projects and expanded recycling and composting programs. Together, these actions contribute to MaineHealth’s systemwide climate goals, which include reducing greenhouse gas emissions by 25 percent by 2027 and achieving net-zero emissions by 2050. Their progress has earned national recognition through Practice Greenhealth Partner for Change awards, highlighting leadership in healthcare sustainability.
