Community action defeats waste burning in cement kilns
Burning waste in cement kilns is another form of incineration, and also wastes resources and results in emissions that are harmful to people''s health and the environment. In order to make cement, hightemperature kilns are needed. Traditionally, coal is used in these kilns, but in the past two decades, many "alternative fuels" have been used.
