The process in Plastcon

Plastcon can turn plastic to oil through pyrolysis – a process where material, in this case plastic, is exposed to high temperatures in an oxygen-free environment. This process results in a chemical and physical separation of the different molecules in the plastic, which have a limited thermal stability and begin to break apart into various components under the right conditions.

Pyrolysis of plastic materials always produces solid waste (such as charcoal), oil vapours/liquid and several non-condensable gases.

Plastcon extracts the liquid and oil vapours from the pyrolysis process and condenses and separates them into gases and oils in its distillation unit. The exact product of the process depends on five parameters:

We handle plastic of any and all types

A unique feature of our Plastcon system is that it is able to accept any type of plastic even PVC and PET, which are commonly regarded as difficult in regards to recycling. Simply, it can convert all types of plastic to oil.

Moreover, our system does not require the plastic to be cleaned or washed when it enters. Any food residue, glass pieces or other contaminants are sorted out in the process.

1. Plastic density

The mass density (weight/volume) of the plastic has an effect on the capacity of the plant (higher mass equals higher capacity).

2. Plastic water content

This influences the energy consumption of the plant as well as the gas and oil liquid yield.

3. Plastic properties

The elementary composition of the plastic – as well as its fixed carbon content, ash content, calorific value, particle size and volatility level – is relevant to the temperature and time consumption of the pyrolysis process. Smaller particles generally decompose faster, which can result in a greater yield of oil.

4. Pyrolysis temperature

The temperature which the plastic is subjected to in the process has a major effect on the final result. High temperatures provide greater quantities of noncondensable synthetic gases, while lower temperatures produce more condensable gases and oil. The temperature also affects the processing time and is precisely controlled.

5. Pyrolysis time

The amount of time that the plastic spends in the pyrolysis reactor affects the degree of thermal conversion of solid waste and the composition of the vapours produced. The pyrolysis time can be regulated by the plant's system process control.
