Under the Pollution Prevention Act of 1990 (PPA), TRI collects information to track industry progress in reducing waste generation and moving towards safer waste management alternatives. Measures that facilities have taken to prevent pollution and reduce the amount of toxic chemicals entering the environment are shown in the table below. Although factors other than these reported practices contribute to year-to-year changes in releases, results are sorted by largest reduction in order to facilitate identification of pollution prevention successes.

As a result, this facility does everything possible to reduce loss via any route. This includes cyclone separation and collection of fines contained in exhaust gasses and reverting of all uncontaminated materials back into the process. The site through customer approval was able to reuse a slugged heat twice in production reducing the amount of materials going off-site to metal recycling.		//enviro.epa.gov/enviro/P2_EF_Query.p2_report?FacilityId=15071CRCBL1001R&ChemicalId=0007440473&ReportingYear=2016&DocCtrlNum=1316215340985&Opt=0
