Responding to the construction industry’s interest in sustainable construction, USG Corp. has expanded the Environmental Responsibility section of its Web site (www.usg.com). The expanded section includes a Product Sustainability Table that covers a wide range of products manufactured by United States Gypsum Company and USG Interiors Inc. The table features specifications on post-consumer and post-industrial recycled content, densities, volatile organic compounds, manufacturing efficiencies and raw materials for each product. In addition, USG has developed specific answers to the ASTM’s Standard Practice for Data Collection for Sustainability Assessment of Building Products as they apply to USG products, manufacturing processes, operational performance, indoor environmental quality and corporate environmental policies. This standard is frequently used as a guideline in answering industry questions about sustainable construction. USG is a founding member of both the United States Green Building Council and the National Safety Council and has earned the Mine Safety and Health Administration’s “Sentinels of Safety” award more than any other U.S. company. The company develops and manufactures products made from natural, recycled and recaptured materials.
