2021 Owens Corning Sustainability Report | Reducing Our Environmental Footprint | Waste Management | 179 50% intensity reduction of waste/byproducts generated from 2018 baseline. This 17% improvement from 2018 is due in part to increased focus on waste generation and operational efficiency improvements across the business. After reducing waste intensity by 50%, repurpose or recycle 100% of remaining waste/byproducts from 2018 baseline. Expanding our use of diversion outlets and end-use applications for our byproducts contributed to this 2% improvement from 2018. By 2030, we will send zero waste to landfill. It’s an ambitious goal, but it can be achieved through our two-part plan: 2030 GOALS FOR WASTE MANAGEMENT We can do this by improving efficiency and process design. Reduce waste intensity by 50% ZERO Waste-to-Landfill We will also recycle waste back into our own processes wherever possible. Repurpose or recycle the remaining waste.
