Owens Corning has released its sixth annual Sustainability Report, which showed year-over-year intensity reductions in all environmental goals set and a list of innovation-driven achievements.

Among the accomplishments highlighted is a reduction in waste-to-landfill intensity by 22% in 2011, which represents an absolute reduction of more than 37,000 metric tons. Owens Corning also reduced its toxic air emissions intensity by 37% last year. That amounts to an absolute reduction of 236 metric tons.
