Pemanfaatan Limbah Plastik Jenis High Density Polyethylene (HDPE) Sebagai Bah…
Plastic has properties that are non-biodegradable or cannot be broken down by decomposing organisms in nature, so plastic requires a very long process to decompose by itself. One method of processing plastic waste is pyrolysis. Pyrolysis is a degradation process of thermal biomass by heat in the absence of oxygen. This research was carried out with the aim of knowing the results of plastic pyro…
