Study of a two steps process for the valorization of PVC-containing wastes

The presence of organic compounds in wastes, namely polymer based compounds, is considered a potential relevant source of energy. However, the presence of polyvinyl chloride (PVC) in their composition, causes recycling problems when a thermal process is considered for the wastes treatment [1] preventing its use on processes which the main goal is the energy recovery (Zevenhoven et al. in Fuel 81:507–510, 2002; ...

Energetic valorisation of PVC-containing waste

Wastes are increasingly regarded as important sources of energy, particularly their polymeric component. However, most of these wastes contain polyvinyl chloride (PVC) in their composition, constraining the use of a thermal valorization process in their treatment [1]. This work aims the development of a process for the material and energetic valorization of the PVC-containing wastes. A two-step process was firs...

Kinetic study of thermal de-chlorination of PVC containing waste

With the increasing of plastics content in solid waste, both municipal and industrial, also increases the interest in its use as an energy source. Some of these wastes are an important potential source of energy and might be valorized using the pyrolysis or gasification processes. However, the presence of high chlorine contents in its composition prevents its management by a thermal process, as consequence of t...
