2013 TRI National Analysis: Waste Management by Parent Company - Parent Companies with the Most Production-Related Waste Managed

Section 4: Waste Management by Parent Company

Parent Companies with the Most Production-Related Waste Managed


Many of the facilities reporting to TRI are owned by parent companies that also own other facilities reporting to TRI. Facilities reporting to TRI are asked to provide information on their parent company if they have one. The parent companies reported to TRI must be located in the United States.

This figure shows the parent companies that reported the most production-related waste in 2013. Eight of these parent companies were also in the top 10 in 2012, while Clean Harbors and E I Du Pont De Nemours moved into the top 10 in 2013.

These parent companies vary in size and in the sectors in which they operate. The number of TRI reporting facilities owned by these companies ranges from 1 to 126. The parent companies’ TRI facilities operate in the following sectors:

  • Metal mining: Teck American
  • Hazardous waste and solvent recovery: Clean Harbors
  • Multiple sectors, e.g. pulp and paper, petroleum refining, and chemicals: Koch Industries
  • Chemical manufacturing: Dow Chemical, Syngenta, Honeywell International, BASF, and E I Du Pont De Nemours
  • Petroleum refining: PBF Energy
  • Metal smelting: The Renco Group

Nine of these top parent companies reported implementing one or more new source reduction activities in 2013. Some companies also reported additional (optional) information to TRI about their pollution prevention or waste management activities. Among the top 10 parent companies, additional information reported included:

  • A Honeywell facility worked with vendor and internal department resources to develop a new formulation for its coating line. This raw material substitution resulted in a 99% reduction in the use of methanol at the facility. (Raw Material Modification) [Facility Details]
  • Through an internal pollution prevention audit and an employee recommendation, a Syngenta facility reduced ammonia emissions by improving ammonia recovery through stripping and optimizing the conditions of reactions that involve ammonia. (Process Modification) [Facility Details]
  • A BASF organic chemical manufacturing plant implemented a site-wide spill prevention plan, focused specifically on over-fill protections and safer chemical transfer. (Spill and Leak Prevention) [Facility Details]
