a Crop residues, normally recycled to land.

b Animal manure, normally recycled to land. Not including emissions from free-ranging animals.

c Values in parentheses are emissions or consumption ( - ) from energy recovery. These values are not included in totals.

d Metal ore mining in the United States.

e Nonmetallic mineral mining in United States, excluding alumina and phosphate concentration wastes.

f Coal mining, not including coke-oven emissions.

g Petroleum and gas drilling.

h Including natural gas processing and transmission. H2O, CO2, and O2 emissions (consumption) based on combustion of process wastes for energy.

i Process wastes of the organic chemical sector are partly combustible and partly incombustible. Detailed breakdown not available.

j Iron and steel slag are by-products with many uses. concentration wastes are included with the mining sector.

k CO2 emissions are included with fuel combustion

NOTES: Plus ( + ) signs refer to production. Minus ( - ) signs refer to consumption. VOC = volatile organic chemical.
