Plastics gained popularity worldwide due to their broad spectrum of advantages, for which they have been used in many industries. Today, 6300 MT of plastics are being manufactured in USA out of which 79% is disposed in landfills and the same for India is 3360043 tonnes per annum out of which 1,344,017.2 TPA is littered. Plastics have made human lives comfortable, but they also have disturbed the environment. Different procedures to treat plastic wastes have been discussed with a special emphasis on pyrolysis technique in terms of its types (slow pyrolysis, fast pyrolysis, flash pyrolysis). The types of plastics that have been reviewed are polyethylene terephthalate (PET), high-density polyethylene (HDPE), low-density polyethylene (LDPE), polypropylene (PP), polystyrene (PS), poly vinyl chloride (PVC). The final products of pyrolysis are gas, liquid and solid residue or char. From literature, it has been observed that the oil yield of PET with and without catalyst during pyrolysis is 34.4 wt% (600 ℃), 11.4 wt% (900 ℃) and 52.9 wt% (600 ℃), 19.3 wt% (900 ℃), respectively. The same for HDPE and LDPE was 94 wt% (5% catalyst) and 93.2% (10% catalyst), respectively. Such product yields for rest of the types have also been given in this chapter. The applications of plastics type in civil engineering have been tabulated and finally a thermo gravimetric analysis (TGA) has been highlighted to assess the pyrolysis products. The TGA analysis is discussed for a better understanding of the optimum temperature to degrade the feedstock into simple compounds.
