Combustion Residues

Current, Novel and Renewable Applications

Millions of tons of combustion residues, in particular fly ash and municipal waste bottom ash, are generated every year in the world requiring utilization or disposal. With the increasing limitation on disposal to landfill because of environmental, economic and space requirements new products and markets are required. The traditional uses in cement and concrete production and road construction are not sufficient to cope with the increasing volume of residues. In addition, the introduction of mixed fuels for power generation and new combustion technologies coupled with the increasing use of incineration for municipal wastes create new challenges for the use of these secondary raw materials′.

This volume on novel products derived from the new generation of combustion ashes:

  • shows how combustion residues, as well as being used in the above traditional outlets, can also be useful source of primary feed materials for a range of industrial high value products such as zeolites; ceramics; glass fibres; glass polyalkenoate cements for biomedical applications; fire resistant materials; fillers for rubber and plastics; etc
  • discusses the nature of ashes derived from coal co–combustion, biomass and other fuels in traditional and stand–alone power plants and municipal waste incinerators
  • discusses the development of novel commercial products incorporating such ashes, including the importance of technical and environmental standards, marketing strategies and promotion
  • presents an example of how one particular industry has approached the problem of introducing new materials into an established industrial process and the difficulties this has caused
  • provides an important source book for research scientists and engineers in the fields of power generation, environment and construction.

This volume is relevant to industries that produce combustion residues or utilize them in their manufacturing processes e.g. power generation, municipal incinerators, cement and concrete manufactures, ceramic industries (e.g. brick and tile manufacturers) and polymer producers. In addition it will be of interest to academics/researchers in civil engineering, materials, fuel and combustion and regulatory bodies, government departments and waste utilization groups.
