ABSTRACT

This piece of study involves degradation of plastic waste in presence of two different catalysts. It was found in gas chromatography (GC) analysis results that in presence of these catalysts more than 80% of polymer by weight was converted into either liquid or gaseous hydrocarbons. These can be utilized as fuel or can be transformed into other useful products. Thermo gravimetric analysis (TGA) and differential scanning calorimetric (DSC) analysis of polymers suggest that presence of these catalysts lowers degradation temperature and change mechanism of degradation.
