∗
Composting of yard trimmings, food scraps, and other MSW organic material. Does not include backyard composting.
†
Includes combustion of MSW in mass burn or refuse derived fuel form, and combustion with energy recovery of
source-separated materials in MSW (e.g., wood pallets and tire-derived fuel).
‡
Discards after recovery minus combustion with energy recovery. Discards include combustion without energy recovery.
Details may not add to totals due to rounding.
