Internet data suggests that in the United States (US), a
range of 7 to 12% of municipal solid waste (MSW) currently is used in waste-to-energy
(WTE) incineration. And, in the European Union (EU), the WTE range is 18 to
23%. The total MSW amount (not just that
incinerated but also recycled/composted and land-filled) appears to be about 265
million metric tons (mt) in the US and about 250 million mt in the EU. These totals are based on assuming that each
person in the US generates about 5 pounds of MSW per day and in the EU about 3
pounds and the US population is 319 million and the EU population is 503
million.
Assurances on exactly what the WTE percentages are seem to
me to be very difficult to pin down. This
is because percentages (found on the Internet) are based on assumptions,
estimates, and surveys and searching the Internet exhaustively can find
different percentages for WTE use. But
most of what is found falls in the ranges given above. With respect to total MSW amounts for both
the US and the EU, total populations used are probably fairly accurate. Pounds of MSW per person are based on a range
of estimates found on the Internet.
The US has long been recognized as significantly lagging the
EU in the use of WTE. However, with the
recent opening of the Palm Beach County, Florida’s WTE plant (apparently the
first US WTE plant to be opened in the last 20 years) and the preponderance of
scientific research, data, and analysis supporting WTE as the best alternative
compared to land-filling, the US may be about to increase its percentage of WTE
use.
Assuming the mid-point (9.5% for the US; 20.5% for the EU) for
the above-provided WTE ranges, the US uses about 25 million mt of MSW per year
in WTE (0.095 X 265 million mt total MSW) and the EU uses about 51 million mt
per year (0.205 X 250 million mt).
Should the US grow to the same level as the EU (20.5%) in its WTE use,
the US would go from 25 million mt per year to 54 (0.205 X 265) million mt per
year in WTE use. The new West Palm
Beach plant is reported to be able to process about 1 million tons (presumably
US not metric tons), so should the US reach an approximate EU WTE percentage
level, more than 30 West Palm Beach-size plants would be needed.
