To reduce waste volume, local governments or private operators can
implement a controlled burning process called combustion or
incineration. In addition to reducing volume, combustors, when properly
equipped, can convert water into steam to fuel heating systems or
generate electricity. Incineration facilities can also remove materials
for recycling.
Over one-fifth of the U.S. municipal solid waste incinerators use refuse
derived fuel (RDF). In contrast to mass burning—where the municipal
solid waste is introduced "as is" into the combustion chamber—RDF
facilities are equipped to recover recyclables (e.g., metals, cans,
glass) first, then shred the combustible fraction into fluff for
incineration.
A variety of pollution control technologies significantly reduce the
gases emitted into the air, including scrubbers, which use a liquid
spray to neutralize acid gases and filters, which remove tiny ash
particles.
