Waste Management Trend Region 10
The following graph shows the 10-year trend in quantities of TRI chemicals managed as production-related waste managedThe sum of all non-accidental chemical waste generated at a facility. It is the sum of on-site environmental releases (minus quantities from non-routine, one-time events), on-site waste management (recycling, treatment, and combustion for energy recovery), and off-site transfers for disposal, treatment, recycling or energy recovery. by facilities in Region 10.
Note: For comparability, trend graphs include only those chemicals that were reportable to TRI for all years presented.
From 2011 to 2020:
- Total production-related waste managed decreased by 457 million pounds (-33%), driven by decreased releases reported by metal mines. Excluding metal mines, waste managed decreased by 26.7 million pounds (-8%).
- Facilities in Region 10 managed 978 million pounds of production-related waste, 72% of which was disposed of or otherwise released, compared to 11% nationally. Metal mines drive the quantity of waste managed in the region, due to large quantities of metal-containing waste disposed to land; for 2020, metal mines managed 66% of all production-related waste managed in the region.
- Since 2019, quantities of production-related waste managed in the region decreased by 22%, driven by decreased disposal quantities from metal mines. Excluding metal mines, waste managed in Region 10 decreased by 48.6 million pounds (-13%).
In 2020, 4% of facilities in Region 10 (28 facilities) reported implementing new source reduction activities. As one example of source reduction in Region 10, an agricultural chemical manufacturer began using a liquid raw material with fewer impurities which generated less filter cake waste containing zinc.
