Section 4: Waste Management by Parent Company

Parent Companies with the Greatest Number of New Source Reduction Activities

This figure presents the parent companies that reported the most newly implemented source reduction activities in 2013. The parent companies’ TRI facilities primarily operate in the following industries:

• Pulp and paper, petroleum refining, and chemicals: Koch Industries
• Chemical manufacturing sector: Valspar, 3M, and BASF
• Petroleum refining and chemicals: Shell Oil
• Bulk petroleum industry (store and distribute crude petroleum and petroleum products): Global Partners
• Metal containers: Silgan Holdings
• Steel manufacturing: Nucor
• Multiple sectors including chemicals, fabricated metals, and industrial equipment: Illinois Tool Works
• Electric utility: Salt River Project

Good operating practices, such as improving maintenance scheduling and installation of quality monitoring systems, are the most commonly reported source reduction activities for these top parent companies. Spill and leak prevention and process modifications are also commonly reported. Some of these parent companies submitted additional text to EPA with their TRI reports describing their pollution prevention activities. Examples include:

• An automotive products manufacturing facility, owned by Illinois Tool Works, reduced the need to flush pipe lines when changing product lines by adding designated pipe lines for specific chemical products. (Process Modification) [Facility Details]
• By switching from a batch manufacturing process to a continuous process, one 3M Co chemical facility reduced total waste of certain glycol ethers. (Process Modification) [Facility Details]
• A BASF organic chemical manufacturer reduced its use of nitric acid by implementing more precise delivery methods and improved metering. [Facility Details]
