research project on a thermo-sensitive sorting process
was carried out at the Institute of Process Development, Peat
and Natural Matter Research (iTN) of the Zittau/Goerlitz University
of Applied Sciences to show a new way of recycling of
plastics. The aim of the research is to evaluate the separability of
plastics with a new sorting process and to clarify relevant influencing
parameters. The laboratory tests involve microwave heating
of plastic specimens in a cavity resonator at a frequency of
2.45GHz and a non-contact temperature measurement by means
of infrared detection. The results confirm the suitability of the
thermo-sensitive sorting process to distinguish many different
types of plastics and reveal the significant influence of parameters
such as microwave heating time, microwave power, particle
size, and water content on the differentiation of plastics on the
basis of microwave heating.
