Source Reduction Activities by Parent Company
Facilities are required to report their parent company information to TRI. For TRI reporting, a parent company is defined as the highest-level company located in the United States that directly owns at least 50% of the company’s voting stock. EPA groups facilities by parent company to assess waste management at the parent company level and identify companies and industries that regularly implement source reduction activities.
The figure below shows the parent companies whose facilities implemented the most source reduction activities for 2022. Facilities outside of the manufacturing sector, such as electric utilities and coal and metal mines, are not included in this chart because those facilities’ activities do not lend themselves to the same source reduction opportunities as the activities at manufacturing facilities.
Note: This figure uses EPA’s standardized parent company names.
Operating Practices and Training, such as improving maintenance or scheduling and installing quality monitoring systems, were the most reported types of source reduction activities for these parent companies. Process and Equipment Modifications were also commonly reported.
Some of the facilities in these parent companies submitted additional text to describe their pollution prevention activities. Examples include:
- A printed circuit board manufacturing facility owned by Amphenol Corp updated equipment and optimized a metal plating process to extend plating bath life and reduce nitric acid usage. [Click to view facility details in the TRI P2 Search Tool]
- A farm equipment manufacturing facility owned by Great Plains Manufacturing Inc. changed the layouts for sheet and plate steel cutting to be more efficient and generate less scrap metal. [Click to view facility details in the TRI P2 Search Tool]
You can find P2 activities reported by a specific parent company and compare facilities’ waste management methods and trends for any TRI chemical by using the TRI P2 Search Tool.
