An attempt was made here for the production and use of waste plastic oil (wpo) oil extracted through pyrolysis and
biodiesel from microalgae (MA). The oil extracted by pyrolysis was blended with MA biodiesel and further added with various
dosage of zinc oxide nano additive for use in CI engine to measure the combustion, performance and pollution characteristics.
The thermal efficiencyof the engine increased by 2.6 % and NOx pollution increased by 5.7 %, HC, CO and Smoke pollutants
decreased with the use of MWP oil and microalgae biodiesel ZnO nano additive blend. Also, the use of SCR at the exhaust
reduced the NOx emission by 76% when compared to the diesel operation.
