1 Introduction
of rejects and sludges totals about 15%, calculated on the recovered paper input
on an air-dried basis. Because landfilling of organic matter has no future in many
countries, most organic waste requires burning in order to reduce its volume.
Effective, clean incineration technologies are available that control flue gas emissions,
and the heat content of the residues and sludges contributes to self-supporting
incineration. The final waste (ashes) can either be discarded or used as raw
materials in other industries. An increasing volume of rejects and sludges can be
used in brick works, the cement industry, and for other purposes.
