Source Reduction Activities by Parent Company in the 2015 TRI National Analysis
See Other Graphics in this Section
This graph shows the parent companies that implemented the most source reduction activities in 2015. The number of source reduction activities reported in 2014 is also shown for reference.
The parent companies’ facilities that reported to the Toxics Release Inventory (TRI) Program primarily operate in the following industries:
- Chemical manufacturing sector: Valspar, Solvay, PPG Industries and 3M
- Multiple sectors, e.g. pulp and paper, petroleum refining, and chemicals: Koch Industries
- Multiple petroleum-related sectors, e.g. petroleum refining, bulk petroleum, chemicals: Chevron
- Metal containers: Silgan Holdings
- Petroleum refining: Northern Tier Energy
- Steel manufacturing: Nucor
- Bulk petroleum industry (store and distribute crude petroleum and petroleum products): Sprague Resources
Good operating practices, such as improving maintenance scheduling and installation of quality monitoring systems, are the most commonly reported source reduction activities for these 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 or waste management activities.
Examples of additional pollution prevention-related information for 2015:
- A PPG Industries coatings facility switched to an alternative raw material for which n-butyl alcohol is not required for its manufacture. (Raw Material Modification) [Click to view facility details in the Pollution Prevention (P2) Tool]
- A Chevron terminal installed spill kits and drain covers in high-risk areas to prevent spills from leaving through storm water drains. (Spill and Leak Prevention) [Click to view facility details in the P2 Tool]
- Through an employee recommendation, a 3M paper manufacturer reduced the volume of methyl isobutyl ketone used by switching to a different process catalyst. (Process Modification) [Click to view facility details in the P2 Tool]
