text: An advanced thermal recycling system (or an ATR system) is an advancement of existing energy-from-waste (EfW) technology. An ATR system transforms municipal solid waste (MSW) into electricity or steam for district heating or industrial customers. The combustion bottom ash and the combustion fly ash, along with the air pollution control system fly ash, are treated to produce products that can be beneficially reused. Specifically, ATR systems consist of the following:
  * Solid waste combustion, boiler and combustion control system, energy recovery and air pollution control equipment;
  * Combustion bottom ash and fly ash treatment systems that produce commercially reusable products; and
  * An optional pre-processing system to recover recyclable materials contained in the MSW delivered to the facility before the MSW enters the thermal processing area of the facility.
