| j TRI National Analysis 2018 LI#/\ www.epa.aov/trinationalanalysis/ \/LI February 2020 Pollution Prevention and Waste Management Each year, the Toxics Release Inventory (TRI) collects information from more than 21,000 facilities on the quantities of TRI-listed chemicals they recycle, combust for energy recovery, treat for destruction, and dispose of or otherwise release both on and off site as part of their normal operations. These quantities, in total, are collectively referred to as the quantity of production-related waste managed. Looking at production-related waste managed over time helps track progress made by industrial facilities in reducing the amount of chemical waste generated and in adopting waste management practices that are preferable to disposing of or otherwise releasing waste into the environment. EPA encourages facilities to first eliminate the creation of chemical waste through source reduction activities. For wastes that are generated, the most preferred management method is recycling, followed by combusting for energy recovery, treatment, and, as a last resort, disposing of or otherwise releasing the chemical waste into the environment in an environmentally safe manner. This order of preference is established in the Pollution Prevention Act fPPAl of 1990 and illustrated by the waste management hierarchy graphic above. One goal of the PPA is that over time facilities will shift from disposal or other releases toward the more preferred techniques in the waste management hierarchy that do not result in releases to the environment. As with any dataset, there are several factors to consider when using the TRI data. Key factors associated with data used in the National Analysis are summarized in the Introduction. For more information see Factors to Consider When Using Toxics Release Inventory Data. Also note that the list of TRI chemicals has changed over the years. For comparability, trend graphs include only those chemicals that were reportable for all years presented. Figures that focus only on the year 2018 include all chemicals reportable for 2018, therefore, values for a 2018-only analysis may differ slightly from results for 2018 in a trend analysis. Waste Management Hierarchy 1 ------- | j TRI National Analysis 2018 LI#/\ www.epa.aov/trinationalanalysis/ \/LI February 2020 Source Reduction Activities Reported Facilities are required to report to TRI new source reduction activities that they initiated or fully implemented during the year. Source reduction includes activities that eliminate or reduce the generation of chemical waste. Other waste management practices, such as recycling and treatment, refer to how chemical waste is managed after it is generated and are not considered source reduction activities. The source reduction information the TRI Program collects can help facilities learn from each other's best practices and potentially reduce their own chemical releases. For more information, see the TRI Source Reduction Reporting Fact Sheet. Source Reduction Activities Reported Good Operating Practices Process Modifications ¦ Spill and Leak Prevention ¦ Inventory Control Raw Material Modifications ¦ Product Modifications ¦ Cleaning and Degreasing ¦ Surface Preparation and Finishing Note: Facilities report their source reduction activities by selecting codes that describe their activities. These codes fall into one of eight categories listed in the graph legend and are defined in the TRI Reporting Forms and Instructions. • In 2018, a total of 3,120 new source reduction activities were implemented by 1,270 facilities (6% of all facilities that reported to TRI). • Facilities select from 49 types of source reduction activities that fall under the 8 categories shown in the graph. The most commonly reported source reduction category is Good Operating Practices. 2 ------- TRI National Analysis 2018 www.epa.aov/trinationalanalysis/ February 2020 o For example, a printed circuit board manufacturing facility reported periodic maintenance of equipment that helps minimize overdosing ammonia into the process. fClick to view facility details in the Pollution Prevention rP21 tooll Additional Resources • See the TRI P2 Data Overview Factsheet for more information on source reduction reporting in recent years. • Note that facilities may have implemented source reduction activities in earlier years which are ongoing or completed projects.

In the pollution prevention hierarchy green chemistry is a means to achieve source reduction. Advancements in green chemistry allow industry to reduce or even prevent pollution at its source by, for example, designing manufacturing processes that use or produce fewer quantities of TRI chemicals, or no TRI chemicals at all. Six of the source reduction codes are specific to green chemistry activities, although green chemistry practices may also fit under other codes. This figure shows the chemicals for which the highest number of green chemistry activities, based on the six green chemistry codes, were implemented over the last five years and the sectors that reported those activities.

I™! 6 ------- oEPA TRI National Analysis 2018 www.epa.aov/trinationalanalysis/ February 2020 Reported Barriers to Source Reduction Facilities that did not implement new source reduction activities for a TRI chemical have the option to disclose any barriers that prevented them from implementing source reduction. Since 2014, TRI reporting forms include barrier codes, which enable reporting and analysis of obstacles that facilities may be experiencing. This figure shows the types of barriers that facilities reported for metals and for all other (non-metal) TRI chemicals. Barriers to Source Reduction Reported for Metals and All Other Chemicals, 2014 - 2018 (O -Q T3 CD +j k_ O Q. CD £ CD U &_ CD Q. 100% 90% 80% 70% 60% 50% 40% 30% 20% 10% 0% Metals I Source reduction unsuccessful Regulatory barriers I Insufficient capital I Further source reduction not feasible I No known substitutes Non-metals I Technical information needed I Reduction not technically feasible I Product quality concerns I Other barriers Note: Facilities report barriers to source reduction by selecting from nine codes that describe possible barriers. These codes are defined in the TRI Reporting Forms and Instructions. From 2014 to 2018: • Facilities reported barriers to source reduction for 333 chemicals and chemical categories. Analyzing the source reduction barriers reported to TRI helps identify where more research is needed, for example, to address technological challenges or promote development of viable alternatives. It may also allow for better communication between 7 ------- v>EPA TRI National Analysis 2018 www.epa.aov/trinationalanalysis/ February 2020 those that have knowledge of source reduction practices and those that are seeking additional help. • The most frequently reported barriers for both metals and non-metals were no known substitutes or alternative technologies and further source reduction not feasible. This excludes other barriers, a catch-all category available to facilities. • While no known substitutes was the most frequently reported barrier for both metals and non-metals, it accounted for almost half (47%) of the barriers reported for metals but made up a smaller portion (37%) of barriers reported for non-metals. • For the no known substitutes barrier for metals, many facilities reported the presence of the TRI metal in their raw materials (e.g., metal alloys) as the reason they did not implement source reduction activities. Examples include: o A sign manufacturer reported that the prime aluminum and magnesium they use in production contains trace amounts of lead as an undesirable impurity. fClick to view facility details in the Pollution Prevention rP21 Tooll o An iron and steel mill noted that manganese is used in steel production to comply with American Society for Testing and Materials (ASTM) standards, so they are unable to reduce their use of this chemical. fClick to view facility details in the P2 Tooll • Further source reduction not feasible was another commonly reported barrier, especially for non-metals. Facilities select this barrier code when additional reductions do not appear feasible. For example: o A plastic product manufacturing facility implemented a recirculation system for bulk storage and an accurate metering system related to its stvrene usage. Further reductions could be realized with the implementation of a robotic application process, but the facility reported insufficient capital to install such equipment. fClick to view facility details in the P2 Tooll • You can view barriers reported for any TRI chemical bv using the TRI P2 Search Tool. 8 ------- oEPA TRI National Analysis 2018 www.epa.aov/trinationalanalysis/ February 2020 Source Reduction Activities by Chemical For the chemicals with the highest source reduction reporting rates over the last 5 years, this figure shows the number and types of activities implemented.
