LONG BEACH - It's the end of lunchtime at Longfellow Elementary School and students are lining up behind purple recycling bins to sort their trash. The bins are divided into six categories: energy bar wrappers, chip bags, plastic bags, city recycling, juice pouches and cookie wrappers. "I like that we recycle in our school because it's good for the planet," said 6-year-old Jenna Jacob, as she recycled her cookie wrapper. For students at Longfellow Elementary at 3800 Olive Ave. in North Long Beach, recycling is more than a lunchtime activity; it's a way of life, said Principal Laurie Murrin. "It's become part our campus culture," she said.
