Air Quality Concerns
Unlike the other renewable energy technologies considered in this report, on-site
use of biomass resources involves atmospheric emissions, solid waste residues
(ash) and possibly water-borne wastes. While the decomposition of waste into
simpler compounds by gasification should reduce emissions, detailed data for
gasification could not be found in the literature (except for coal and clean wood).
It may be expected, however, that emissions from a gasification operation could
be no worse than those of a direct-burn operation which may be found in the
56
