Pyrolysis of municipal plastic wastes: Influence of raw material composition

Thermal and catalytic pyrolysis of plastic waste

“…Tertiary recycling of plastic waste containing PVC releases hydrogen chloride, which causes corrosion of the pyrolysis reactor and formation of organochlorine compounds [23] . The presence of chlorine is very harmful for use as fuel in the pyrolysis liquid products obtained [24] . Although plastic waste may be considered economical sources of chemicals and energy, recycling of mixed plastic waste containing PVC not only result in the formation of volatile organic compounds in products, also in the emission of pollution when they are applied [23] .…”

Looking Behind the Process of Pyrolysis in Waste Management: Questions on the Composition and Quality of End-Product and Their Answers by Meas of Analytical Chemistry

“…Despite the differences in the findings in issues of temperature, or catalyst, researchers generally agree on the significance of the chemical composition of raw waste to be pyrolyzed. Spanish researchers studied intensively (López et al, 2010) the question of pyrolysis raw materials and their effects on the composition of end-product. They studied four different types of incoming wastemixtures rejected from waste management plants: samples 1 and 2 contained more than 90 wt% packaging plastics while such materials were much less abundant in samples 3 and 4, which contained more than 30 wt% of materials inappropriate for pyrolysis.…”

First Simple and Easy Process of Thermal Degrading Municipal Waste Plastics into Fuel Resource

“…In accordance with wave number compound are elaborated such as wave number 2956. 38 Comparative study of HDPE-2, LDPE-4, PP-5 & PS-6 fuel emerging that in different band and wave number different functional groups and compound derived. In some cases wave number are matches with one wave to another wave number including compound identification is also found same compound or group.…”

“…Even though, current technologies would conform the emission requirements, incineration arouses almost always public resistance and objections [6,7,8]. Some research group also worked with plastic conversion into fuel catalytic process [9][10][11][12][13][14][15][16][17][18][19][20], thermal degradation process [21][22][23][24][25][26][27][28][29][30][31][32][33] and pyrolysis process [34][35][36][37][38]. Natural State Research, Inc. (NSR) invented a unique process which easy and simple way to converted most of waste plastics into fuel resources and investigated that the reaction of experiment continues randomly without any catalyst or chemical substances.…”
