35. What kinds of plastics are used for food
handling and storage and are there any
health hazards of using it?
Plastic packaging plays a signification role in the shelf
life and ease of storage and cooking for many foods
and most are safe to use provided that they are used
appropriately.
1. Polyethylene terephthalate (PET) is used to make
soft drink, water, sports drink, ketchup, and
salad dressing bottles, and peanut butter, pickle
jelly and jam jars. It is strong, heat resistant and
resistant to gases and acidic foods. It can be
transparent or opaque. Not known to leach any
chemicals that are suspected of causing cancer
or disrupting hormones and it can be recycled.
2. High density polyethylene (HDPE) ……
3. Low-density polyethylene (LDPE) …..
4. Polypropylene (PP) …..
5. Polycarbonate ……
In addition, polystyrene (PS) and polyvinyl
chloride (PVC) are also used during food material
transportation and handling in supermarkets.
Modern food safe plastic bags are plasticizer-free
and will not release harmful chemicals into your food
while it is being cooked.

Recyclability of PET/plastics

Reprocessed for use in manufacture
Tertiary recycling
Production of basic chemicals and fuels
Quaternary recycling

Miscreants damage
machines installed this
month at Western
Railway stations
Vedika Chaubey, Mumbai
MARCH 27, 2017
Less than a month after they were
installed, two machines that crush
plastic bottles have been damaged.
Western Railway officials said the
machines at Bandra and Andheri
stations were tampered with when
miscreants tried to steal cameras and
speakers fitted on them.
Wockhardt Foundation had installed
the bottle crushers at a cost of Rs 7
lakh each at 10 stations, including
Churchgate, Santacruz, Goregaon
and Borivali, on the western
suburban railway line. The company
has spent nearly Rs 30,000 to repair
the machines.

Plastics in Roads
• The plastic can be shredded to the right size and
incorporated right into the tar.
• The plastic melts and lends its qualities to the
road.
• The entire process is much more eco-friendly
than plastic being recycled since no toxic fumes
are vented.
Plastone Blocks
• Made from a mixture of waste plastic and
stones/granite waste/ceramic waste
• Withstands more pressure and resist water
percolation
• Many advantages over conventional blocks of
cement

Established
knowledge
• Annual growth
~9% (currently .260
Mt/year)
• ~8% of world oil
production is used
• ~33% used for
disposable items
of packaging
Concerns &
uncertainty
• Is our usage of
hydrocarbons for
plastics
sustainable?
• Biopolymers -
• To what extent
they can replace
oil-based plastics?
• Is land available
for production of
biomass?
Recommendations
• Increase/incentivize material reduction & reuse
• Extensive LCAs
• Develop
alternative
monomers,
polymers and
additives using
green chemistry
approaches
• Standards &
labelling of
recyclable,
‘degradable’,
‘biodegradable’

Established
knowledge
• Domestic and
industrial wastes in

• Recycling of some
polymers (e.g. PET)
increased
considerably, but not
for all plastics
• Biodegradable plastics
can compromise
recycling – need
industrial composting
(not readily
degradable in landfills)

from plastics in landfill
• Degradability/
environmental fate of
additives used in
biodegradable
polymers?
Recommendations
• Increase/incentivize
product design for:
• Use of recycled
feedstock
• Increased end-of- life
recyclability
• Innovations in collection
& separation of plastic
waste

Challenges in Waste Management : Post-use
fate of Plastics
Established
knowledge
• plastic debris present
in marine habitats,
incl. poles and deep
sea
• plastic debris is
increasing/stabilizing
(not declining)
• plastic debris is
fragmenting into
micro-plastics (<20
mm)
Concerns &
Uncertainty
• Mechanism of formation
of micro-plastics not
fully understood
• rates of accumulation of
debris on land, in
freshwaters and in
deep-sea are not certain
• do biodegradable or
compostable plastics
degrade in natural
habitats?
Recommendations
• education, engagement &
enforcement for:
• use of used plastics as
feedstock for recycling
• Prevention of
wasteful & adverse
ecological effects
• cleaning programmes
in natural, urban and
industrial locations
• develop standard
protocols to monitor plastic
debris
• research on breakdown of
degradable &
biodegradables

43. Life Cycle Assessment
Definition:
• “Compilation and
evaluation of the inputs,
outputs and the potential
environmental impacts of a
product system throughout
its life cycle”
• This establishes an
environmental profile of
the system!
ISO = International
Organization for
Standardization
Ensures that an LCA is
completed
in a certain way.
WHAT CAN BE DONE
WITH LCA?
1. Product or project
development and
improvement
2. Strategic planning
3. Public policy making
4. Marketing and eco-
declarations

45. Plastics – boon to mankind
As we approach the 10 billion population mark
• Pressure on land for food vs fuel vs fibre vs packaging material
• Water security challenges
• Increasing aspirations – for hygiene, modern materials
PET/Plastics helps civilizational progress:
• Lowest ecological footprint compared to paper, textiles, glass or metals
• Safest – no leaching
• Most convenient (non-fragile, lighter, versatile, cost-effective)
• Recyclable
• Amenable to innovations
• Releases land for much needed requirements of food
Plastics: Release land for food and meet the increasingly aspirational society
