We define small-scale as over 20 - 75 kTpa and medium scale as 75 - 250 kTpa

This Rating Report includes all types of high temperature thermal processing, not just classical moving grate incineration.  Plasma companies, gasification technologies and a few pyrolysis processes are included where they are targeted at the above scale of application.  In addition to moving grate incineration systems, there are some fluidised bed technology supplers who also target this application and who are therefore included.

Systems from all over the world are included and the list is relatively comprehensive.  Normally we list technologies under the company that is the process developer and not under local agents or engineering partners.  In some instances however we have listed other companies with whom a technology is often associated, such as a licensee for a particular region of the world.

We have also separated out the applications covered to identify where a process is specifically targeted at only one particular feed.  Feedstocks covered include MSW ‘black bag’ waste; the residual fraction after recycling (grey bag waste’); and more homogeneous fuel fractions (such as RDF,SRF PEF or RRBF). There may be multiple ratings for some processes where these processes aim to be accepted for several types of input.

Where the energy recovery method is not spelt out it is assumed to be generation of electricity via the steam cycle.  If other routes are being pursued (such as gas engines or gas turbines) this is noted and our rating reflects the extent to which this integrated concept has been demonstrated.
