Stonyfield Farm makes studied switch to PLA for yogurt multipacks

摘要

The world's largest organic yogurt producer, Stonyfield Farm, Londonderry, NH, has embraced bioplastics, launching new plant-based packaging for all of its multipack form/fill/seal containers. The new polylactic acid cups, made from Ingeo? resin from NatureWorks LLC, replace previous packaging made from high-impact polystyrene, resulting in 48% less greenhouse gas emissions. "When we do packaging initiatives, we usually try to reduce GHGs by at least 5 percent," Stonyfield vice president of Natural Resources Nancy Hirshberg told Packaging World in an exclusive interview before the October 13 launch. "When we approached this project, it was really a priority for us to get out of polystyrene. We were hoping it would be at least a net neutral. So when we got the life-cycle assessment back, we were stunned."
