A Bangor hospital is taking care of people and the planet, too. Displays set up Monday in the cafeteria at St. Joseph Hospital show how the building is getting more environmentally friendly. Special flooring, paint, and lighting is used to reduce electric costs and the hospital is also trying to reduce waste. ” Zero-sort, we implemented a couple years ago, we’re doing a wonderful job with that. We’re generating about 3 tons a month out of our compactor out back. We’re also educating employees on some of the new technology with lighting,” said Rick Labrecque, supervisor of housekeeping and laundry. Low-flow shower heads were given away as raffle prizes during the Earth Day event.
