Plastic pyrolysis is a distillation process used to transform plastic waste into fuel. The waste is heated to more than 400°C in a first tank and is transformed into gas. Depending on the condensation (cooling) temperatures of this gas, different types of fuel are obtained: | |||
- between 390 and 170°C, condensed gas produces diesel (diesel). | |||
- between 210 and 20°C, condensed gas produces gasoline. | |||
- below 20°C, there remains non-condensable residual gas which can be used to supply the heating of the process. | |||
As part of this prototype, only polypropylene (PP) and/or high density polyethylene (HDPE) and low density polyethylene (LDPE) are used. Note that a majority of polypropylene will give more gasoline, just as a majority of polyethylene will give more diesel. However, it is possible to mix the two. | |||

Plastic pyrolysis is a distillation process used to transform plastic waste into fuel. The waste is heated to more than 400°C in a first tank and is transformed into gas. Depending on the condensation (cooling) temperatures of this gas, different types of fuel are obtained:
- between 390 and 170°C, condensed gas produces diesel (diesel). - between 210 and 20°C, condensed gas produces gasoline. - below 20°C, there remains non-condensable residual gas which can be used to supply the heating of the process.As part of this prototype, only polypropylene (PP) and/or high density polyethylene (HDPE) and low density polyethylene (LDPE) are used. Note that a majority of polypropylene will give more gasoline, just as a majority of polyethylene will give more diesel. However, it is possible to mix the two.
For this test, plastic waste is mostly polypropylene.
Preheating is necessary. It allows for the condensation of gases at high temperature before passing through the last two tanks.
Let plastic waste consume itself until non-condensable gas forms. It comes as an addition to the gas initially used. For this test, 125mL of canister gas has been used, to which has been added residual gas.
Here, the machine was heated during roughly one hour. Switch off the system and let it cool down before opening the tanks. We get around 125mL of fuel in tank n°2 and 30mL of fuel in tank n°3.
