4. WHAT IS PYROLYSIS
?
“Pyrolysis is the thermal
decomposition of organic material
at elevated temperatures, in the
absence of gases such as air or
oxygen.”
Endothermic Reaction
PYROLYS
IS
pyro means “Heat”
lysis means “Breakdown”

6. Why
Co-Pyrolysis?
Co-pyrolysis constitutes
the pyrolysis of more than
one type of feedstock,
resulting in a positive
synergistic effect. This
positive synergistic
interaction due to the
mixing of feedstocks during
pyrolysis has led to
efficient oil content in
combination with a secure
and alternative way to
handle non-biodegradable
waste. It is cost-efficient
method.

9. FEEDSTOCK
Packaging Industry Waste
Human currently produce more than 350
MMT of plastic waste per year.
Approximately 63 wt% of this waste comes
from packing and packaging.
Bidi Industry Waste
Bidi industry generates waste such as
discarded tobacco leaves, packaging
materials, and other byproducts. Proper
waste management practices are
essential to address environmental
concerns associated with the bidi
industry.

10. Process of
Pyrolysis
Stage 1:
FEEDSTOCK
PREPARATION
Solid waste material is sorted
and grinded.
Stage 2:
DRYING
Moisture content of
biomass is reduced
through heating
Stage 3:
PYROLYSIS
Decomposition of the feed
into bio-oil, syngas and
char takes place in the
absence of oxygen
Stage 4:
COOLING
Byproducts are cooled and
collected for further
processing and utilization

13. PROS
 Simple, inexpensive
technology and
environmental friendly
 Waste Management
 Reduce the country’s
dependence on
imported energy
resources by
generating energy
from domestic
resources
CONS
 Requires dry product.
 Ineffective in
destroying and physical
separating inorganic
compound from
contaminated medium.
 Requires proper
treatment, storage and
disposal of hazardous
wastes

14. Application of Pyrolysis
Chemical industry: to produce methanol, activated carbon,
charcoal
Building material: mixture of stone, soil, ceramics and glass
obtained from pyrolysis waste can be used as a landfill cover
liners
Electricity: syngas can be used in gas or stream turbines for
producing electricity
Cooking: grilling, frying and baking
