This document defines and describes different types of wastes: biodegradable waste, non-biodegradable waste, and electronic waste. Biodegradable waste includes materials from plant and animal sources that can be broken down by other living organisms, such as food scraps. Non-biodegradable wastes like plastic do not degrade and can pollute the environment. Electronic waste, or e-waste, refers to discarded electronic devices. The document outlines challenges with each type of waste and stresses the importance of reducing, reusing, and recycling to properly manage wastes.

2. Types OF Wastes
Biodegradable Waste Non-Biodegradable waste Electronic Waste

3. Biodegradable waste
is a type of waste ,typically
originating from plant, animal sources,
which may be degraded by other living
organisms.

5. Biodegradable waste can be commonly
found in muncipal solid waste
(sometimes called biodegradable
muncipal waste).

6. Types of Biodegradable
waste:-
Vegetable peels
Manure
Sewage
Slaughter house

11. Climate change impacts
• The main enviromental threat from biodegradable
waste is the production of methane in landfills.
Methane is 21times as potent a greenhouse gas as
CO2 and accounted for some 3% of total green
house gas as emissions in the EU-15 in 1995.The
Landfill directive 1999/31/EC obliges member
states to reduce the amount of biodegradable
waste that they landfill to 35% of 1995 levels by
2016, which will significantly reduce the problem.

13. Use of biodegradable waste:-
Biodegradable waste can often by used for
composting or must doubtlees be a resource for
heat, electricity and fuel in future as it is begin
achieved by the swiss Kompogas treatment for 20
years now.

14. Non-Biodegradable
waste
• Waste that can’t be broken down by other living
organisms are called by Non-biodegradable waste.

16. Types of Non-biodegradable
waste:-
Plastic
Polythene bag
Plastic bottle

17. Problems of Non-biodegradable
waste:-
Blocking grains
Killing cows & any other animals.

18. Non-biodegradable plastic waste:-
• Plastic wastes present formidable problems as they
are at present not biodegradable, are bulky and
can resist incineration. Incineration in fact may
not be possible due to production of noxious or
toxic fumes. Inadequate levels of recycling
aggravate the waste problem. In addition, in a
world where plastic production may , in a decade,
reach over 60 million metric tons per year, plastic
waste is a major loss of an important commodity.

19. Companies such as coca cola and Pepsi have
captured major market shares in India, but
have not taken any interest in ensuring
the plastic bottles are recycled. While the
old glass bottle were reused, PET scrap is
not worth enough to ensure recovery
because the two PET recycler are
importing subsidized scrap from Europe
and U.S.A.

21. As a result, plastic bottles and thin-film
bags are littered everywhere in India,
blighting heritage areas, blocking drains
and killing cows. Laws requiring use of
virgin materials and thicker bags have
not solved the problem.

& non-biodegradable

24. Types of electronic waste :-
Mobile phone
Computer
Television
Microwave
Refrigrators

25. Definition of e-waste
• Electronic waste may be defined as discarded computers,
office electronic equipment, entertainment devise electronics,
mobile phones, televisions, refrigerators. This definition
includes used electronics which are destined for reuse,
Resale , salvage, recycling , or disposal. Other define the re-
usable and secondary scrap to be “commodities” , and reserve
the term “waste” for residue or material which is dumped by
the buyer rather than recycled , including residue from reuse
and recycling operations.

27. Because loads of surplus electronics are frequently commingled, several
public policy advocates apply the term “e-waste” broadly to all
surplus electronics .Cathode ray tubes (CRT) are considered one of
the hardest types to recycle. CRTs have relatively high
concentration of lead and phosphors, both of which are necessary
for the display . The united states Enviromental protection agency
(EPA) includes discarded CRT monitors in its category of
“hazardous household waste” but considers CRTs that have been
set aside for testing to be commodities if they are not discarded,
speculatively accumulated, or left un protected from weather and
other damage.

28. Debate continues over the distinction
between “commodity” and “waste”
electronics definitions. Some exporters are
accused of deliberately leaving difficult-
to-recycle, obsolete, or non-repairable
equipment mixed in loads of working
equipment. Protectionists may broaden
the definition of “waste” electronics in
order to protect domestic markets from
working secondary equipment.

29. The high value of the computer recycling
subset of electronic waste ( working
and reusable laptops , desktops, and
components like ram) can help pay the
cost of transportation for a large
number of worthless pieces than can be
achieved with display devices, which
have less (or negative) scrap value.

30. Problems
Rapid changes in technology, changes in media
(tapes, software, MP3), falling prices, and
planned obsolescence have resulted in a fast-
growing surplus of electronic waste around the
globe. Dave Kruch, CEO of cash for laptops,
regards electronic waste as a” rapidly expanding”
issue. Technical solutions are available, but in
most cases a legal framework, a collection system,
logistics, and other services need to be implemented
before a technical solution can be applied

31. An estimated 50 million tons of E-waste is produced
each year. The USA discards 30 million computers
each year and 100 million phones are disposed of
in Europe each year . The enviromental protection
agency estimates that only 15-20% of e-waste is
recycled, the rest of these electronic go directly into
land fills and incinerators. “EPA estimates for
2006-2007.

32. According to a report by UNEP titled, “Recycling-
from E-Waste to resources,” the amount of e-
waste being produced – including mobile phones
and computers – could rise by as much as 500
percent over the next decade in some countries,
such as India . The united states is the world
leader in producing electronic waste, tossing away
about 3 million tons each year.

33. China already produces about 2.3 million tons
domestically, second only to the united states.
And, despite having banned e-waste imports,
china remains a major e-waste dumping ground for
developed countries.
