This study aims to evaluate the efficiency and product characteristics of oil produced through the pyrolysis process from two types of raw materials: LDPE (Low-Density Polyethylene) plastic waste and B3 waste (hazardous and toxic waste). The tests included oil yield, flash point, fire point, density, and viscosity. The experimental results show that B3 waste has a higher oil yield (49.29%) compared to LDPE (36.59%), although both values are lower than the optimal results found in the literature, which can reach 84.32% (LDPE) and 90% (used oil). Analysis of the physical properties of the products showed significant variations. The flash point ranged from 122.4°C to 425.5°C, and the fire point from 212.6°C to 554.9°C, with the lowest values obtained from LDPE collected at the final condenser. This variation indicates that the resulting oil product is a mixture of heavy and light hydrocarbon fractions. Meanwhile, the product's density values (0.7824 - 0.8377 g/ml) and viscosity (4.382 - 8.903 cStokes) show good consistency with data reported in scientific journals, validating these experimental results. In conclusion, although the process is not yet fully optimized, the utilization of B3 waste proved to be more efficient in terms of yield, and the resulting oil product has the potential to be used as an alternative fuel after further purification
