The thermal degradation of the mixture of waste HDPE & LDPE defined as WPB, in the ratio of 3:1 by wt% and the mixture of jute, HDPE & LDPE defined as JFWPB in the ratio of 1:3:1 by wt%, was carried out in a self designed, laboratory scale, stainless steel reactor in the oxidative environment. The reactor was heated up to 180 degrees C with a heating rate of 1 degrees C/min, by using the digital temperature controller. The recovered liquid yield from WPB was reported less than 5% which had been improved upto 56% with JFWPB. The comparatively FTIR analysis of both the samples revealed that unsaturated hydrocarbon fragments were transformed in to the oxygenated products which were confirmed by GC/MS analysis and identified as a phytol, free fatty acids and silica derivatives by using NIST library. The saponification value, acid value, ester value, % free fatty acids and % glycerol for Oil(JFWPB) was found close to the coconut oil. (C) 2016 Elsevier Ltd. All rights reserved.
