Proses Pirolisis Limbah Plastik High Density Polyethylene (Hdpe) Menjadi Bahan Bakar Minyak (Bbm)

ABSTRACT
The high-density polyethylene (HDPE) plastic bags, more commonly known as
"kantong kresek" in Indonesian, have become the most prevalent plastic waste
polluting the environment. The plastic, composed of long-chain hydrocarbon
molecules, is highly resistant to natural degradation, necessitating technologies
that can manage plastic waste without creating new waste. The pyrolysis process
has proven to be successful in treating plastic waste. Pyrolysis can thermally
degrade long-chain polymer molecules into smaller molecules. This research aimed
to process HDPE plastic waste, categorized into colored and non-colored plastics,
into fuel oil using pyrolysis with two parallel reactors. Each reactor contained 500
grams of HDPE plastic waste, which was heated to a temperature of 370°C for
approximately 2 hours in reactor A. The pyrolysis gas was directed into reactor B.
In reactor B, the gas was separated at three different heating temperature ranges:
100–175°C, 175–270°C, and 270–360°C. The pyrolysis process yielded yellow,
yellow-brown, and brown oils for colored and non-colored plastics, with similar
total yields of 76.2% and 75.4%, respectively. The separation temperature variation
had a significant impact on oil yield. The highest yield was obtained at temperatures
of 270-360°C for colored plastic (32.4%) and 175-270°C for non-colored plastic
(29.7%). From the physical property tests, it was observed that the separation
temperature affected the density, viscosity, and flash point of the oil. The calorific
value of all produced oils ranged from 11.53-12.01 kcal/g, higher than Pertamina's
standard.
