THERMAL DEGRADATION OF WASTE POLYOLEFINES AND THEIR APPLICATION IN BLAST-FURNACE PROCESS

Monika Kuźnia, Aneta Magdziarz

Abstract


Nowadays about 60% of world production and consumption of plastics are polyolefines. They are used as packaging, in building engineering, automotive industry or electronic engineering. High calorific value and proper Chemical composition of polyolefines (based on carbon and hydrogen) make them ideal for use in a wide range of applications. The polyolefines can be used as a substitute for coke in blast-furnace processes. This paper outlines thermal decomposition of PE-LD, PE-HD, PP which are used in agriculture and packaging from household. Thermogravimetry (TG) and Differential Scanning Calorimetry (DSC) were used as analytical methods.


Keywords
