The Main Elements of an Advanced Thermal Technology Energy Plant
Waste Reception, Handling and Pre-treatment

The pyrolysis and gasification process is focused on treating the organic based materials present in MSW (e.g. paper, plastics, card, putrescible waste, green waste).

Therefore, non combustible materials and recyclables, (typically metals and glass) may be removed prior to the thermal treatment reactor stage. In addition and depending on the technology employed, the feed material might require processing to remove excess moisture, and shredding to reduce the size.

It is the preference (for most ATT processes) to treat only pre-processed MSW that makes these systems appropriate to be integrated into a wider municipal waste management strategy.

ATT processes may for example be used in conjunction with sorting technologies such as those employed in Mechanical Biological Treatment plant.

Some MBT plant are designed to produce a fuel stream (primarily composed of paper, card and plastics) as one of the outputs from the process. This is commonly referred to as refuse derived fuel or RDF.

This may be more amenable to processing in an ATT plant rather than raw MSW.
