This is a presentation on fuel from plastic waste mainly for mechanical engineering or for environmentalist.

3. SCOPE OF CONVERSIONOF PLASTICS INTO FUEL
In this scenario, my presentation aims to solve
the twin problem of environment pollution
due to plastic and the need for an alternative
fuel source.
The main aim is to find a solution to the
mountings problem of plastic disposal, for
which the plastics are converted into valuable
fuel.

4. PLASTICS
Plastics are non-degradable
polymers mostly containing
carbon, hydrogen and few
others elements such as
chlorine, nitrogen etc.

5. DEMAND FOR FUEL
The present rate of economic growth is
unsustainable without saving of fossil
energy like crude oil, gas or coal. Thus
mankind has to rely on the
alternate/renewable energy sources
like biomass, hydropower, geothermal
energy, wind energy, solar energy,
nuclear energy, etc.

6. WASTE PLASTICS
• Waste plastics are one of the most
promising resources for fuel production
because of its high heat of combustion
and due to the increasing availability in
local communities.
• The conversion methods of waste
plastics into fuel depend on the types of
plastics to be targeted and the
properties of other wastes that might be
used in the process.

9. PYROLYSIS
PYROLYSIS IS A PROCESS OF THERMAL
DEGRADATION OF PLASTICS IN THE
ABSENCE OF OXYGEN.

11. PRINCIPLE OF PYROLYSIS
• When the long chain of plastic polymers breaks at
certain points or when lower molecular weight fractions
are formed it is termed as depolymerisation.
• In the process of conversion of plastics into fuel, random
depolymerisation is carried out in a specially designed
reactor in the absence of oxygen and in the presence of
coal and catalytic additives.
• There is total conversion of waste plastics into value
added fuel products.

12. CATALYTIC CRACKER
 Catalytic cracking is the breaking of large hydrocarbon
molecules into smaller and more useful bits.
 The cracker must be designed in such a way that the
vapour from the reactor must have maximum surface
contact with the catalyst.
 The catalyst will act as a molecular sieve which permits
the passage of small molecules.
 The hydrocarbon molecules are broken up in a fairly
random way to produce mixtures of smaller
hydrocarbons, some of which have carbon-carbon double
bonds.

14. 2. CONDENSER

15. CONVERSION OF PLASTIC INTO FUEL
• The entire process is undertaken in a closed reactor
vessel followed by condensation process.
• Waste plastics while heating up to 2700 to 3000 degree
Celsius convert into liquid-vapour state, which is
collected in condensation chamber in the form of liquid
fuel.
• The organic gas which is generated can be used in dual
fuel diesel generator set for generation of electricity.
• The slurry liquid waste is topped down from the heating
reactor vessel.
