Pyrolysis is a thermochemical treatment, which can be applied to any organic (carbon-based) product. It can be done on pure products as well as mixtures. In this treatment, material is exposed to high temperature, and in the absence of oxygen goes through chemical and physical separation into different molecules.

2. INTRODUCTION
Pyrolysis means subjecting plastic to high temperature of 400
to 450 degree Celsius, in absence of oxygen. In case of oxygen
is present, plastic will start burning. During pyrolysis plastic
breaks down into smaller molecules of pyrolysis oil, pyrolysis
gas and carbon black. Pyrolysis is a great way of recycling
waste plastics. This waste plastic pyrolysis plant can be used
for waste plastic recycling.

3. WORKING OF A
PYROLYSIS
PLANT
1. Feed raw materials into the reactor
by full automation feeding machine.
The reactor is supposed to be left 1/3
space for rotating more smoothly.
2. Reactor will be gently heated by
burning fuel material.
3. After all fuel oil produced the
reactor should be cool down.
4. There possibly will be a little
exhaust gas, please expel it after
reaching emission standard.

4. GENERATION/CONVERSION
TECHNIQUES
USED FOR THE SOURCE OF ENERGY
Conversion techniques mainly include-
1. Incineration
2. Gasification
3. Hydrolysis
4. Anaerobic digestion
5. Pyrolysis
6. Chemical feed recovery

5. Depolymerization
Technologies
The result is the generation of
Poly-fuel- “green” synthetic (fuel) oil
Poly-carbon- soot (carbon black)
Poly-gas- synthetic gas
-Environmentally friendly, dealing with the comprehensive issue
of waste disposal.
-Energetically independent, using the input material for its own
operation, while at the same time, it is possible to generate
electric power and heat (CHP) and comprehensively- ecologically-
utilize waste polymers.

6. Pyrolytic Conversion Technologies
1. Pretreatment- this could be as minor as size reduction or as
involved as cleaning and moisture removal.
2. Conversion-pyrolytic processes are used to convert the plastic
to a gas.
3. Distillation- the gas is converted to liquid form.
4. Acid removal process- removal of acids that form in the
breakdown of some scrap plastics. These acids require removal
because they can be corrosive to the PTF systems as well as the
engines that will consume the fuel.
5. Separation/refining/final blending- the final steps required to
make this product consumer ready can neither be done on site
or by a third party, depending on the system design.

9. UTILITY OF THE ENERGY SOURCE IN THE
FUTURE-
Key benefits of pyrolysis include-
•It reduces waste going to landfill and green house gas emission.
•It reduces the risk of water pollution.
•It has the potential to reduce country's dependence on imported energy
resources by generating energy from domestic resources.
•Waste management with the help of modern pyrolysis technology is
inexpensive than disposal to landfills.
•The construction of a pyrolysis plant is a relatively rapid process.
•It creates several new jobs for low income people based on the
quantities of waste generated in the region, which in turn provides
public health benefits through waste cleanup.

10. Effect on the
environment-
•Energetically self-sufficient.
• Complete recycling of plastics and tires.
•Clean process because there is no usable waste
recycling so it does not generate environment
liabilities.
•Fitting in clean production liabilities.
