Abstract

There is provided a process for the thermal treatment of waste materials, particularly pharmaceutical waste materials. The process comprises placing the waste material into a chamber and increasing the temperature inside the chamber in three stages. At a first stage, water in the material is desorbed as water vapor. At a second stage, organic ingredients in the material are desorbed and decomposed producing condensable organic vapor and non-condensable synthesis gas. And at a third stage, polymer-based components of the material are depolymerized and decomposed producing condensable hydrocarbon vapor. The non-condensable synthesis gas produced can be used as heating source for the process.
