This web site has been prepared to illustrate the key aspects of the technologies available for treating municipal waste in 2004.
Many of the descriptions provided are generic or based on 'typical' examples of the technologies. The reason for this is the wide diversity of options available in some systems (Anaerobic Digestion, MBT, In-vessel Composting and Pyrolysis and Gasification, in particular).
Each technology is accompanied by a schematic diagram illustrating typical inputs and outputs of the processes, the key for these diagrams is as follows:-
Key to the schematic diagrams in each section
Waste Input Technology Output as waste / fuel / recyclate
Emission to air Emission to Water Output to electricity generation
In addition to the technologies included there is also a section on dedicated pre-treatment processes which may form part of an integrated waste management solution.
The policy matrix section is a matrix showing how the technologies relate to current UK environmental policies. There may be exceptions to the results in this matrix as in some instances the result is dependent upon specific configurations of technologies and the interpretation of policies.
January 2012 Update:
Over the last 8 years since this web site was conceived there has been significant development of a number of technologies which are commonly now referred to as "Heat (Thermal) Treatment". We have added a page to provide further information on this subject here.
