MHT involves a mechanical sorting or pre-processing stage with technology often found in a material recovery facility.
The mechanical sorting stage is followed by a form of thermal treatment.
This might be in the form of a waste autoclave or processing stage to produce a refuse derived fuel pellet.
MHT does not however include a stage of biological degradation (anaerobic digestion or composting).
Different MHT systems may be configured to meet various objectives with regard to the waste outputs from the process.
