The document discusses different types of waste - solid, liquid, and gaseous - and how they affect human health and the environment. It provides examples of each waste type, such as garbage and rubbish being solid waste, wastewater being liquid waste, and gases from automobiles and factories being gaseous waste. The document also discusses proper waste management practices like reducing, reusing, and recycling waste.

11. What is Waste?
• UNWANTED OR
UNUSABLE materials
• Waste is any substance
which is discarded after
primary use, or it is
worthless, defective or
no use.
12. What is Waste?
• Urbanization and rapid
advancements in
industrialization has led
to an increase in the
production and
consumption processes
resulting in the
generation of wastes.
13. HOW WASTE IS GENERATE?
• Waste are generated from variety of
sources: household. Commercial
establishments, industrial processes,
agricultural and from others.
• Waste is generated in small, medium and
large cities and towns are about 0.1kg, 0.3
kg, 0.4 kg and 0.05 kg per day
respectively.
15. SOLID WASTE
Solid form, non- soluble
materials ranging from
municipal garbage to
industrial wastes that contain
complex and sometimes
hazardous substances”
17. LIQUID WASTE
Liquid form such as chemicals,
oils, and waste water from ponds
and manufacturing industries.
It includes sewage as well as
wastewater from industrial
processes and agricultural
processing.
In general, the waste maybe classify as
follows
18. LIQUID WASTE
Wastes generated from washing,
flushing or manufacturing
processes of industries.
In general, the waste maybe classify as
follows
19. GASEOUS WASTE
These wastes released in the
form of gases from
automobiles, factories, burning
of fossil fuels. etc and get mixed
in the atmosphere.
In general, the waste maybe classify as
follows
20. GASEOUS WASTE
These gases includes carbon
monoxide, sulphur dioxide,
nitrogen oxide, ozone, methane
etc.
In general, the waste maybe classify as
follows
21. Classify each waste produced based on its
source.
• SOURCE OF WASTE
1.Urban or Municipal Wastes
2.Industrial Wastes
3.Commercial wastes
4.Agricultural wastes
26. WASTES ACCORDING TO
GENERATION
• MUNICIPAL SOLID WASTES
• Mixture of paper, plastic, clothes,
metals, glass, organic matter etc.
• Generated from households, commercial
establishments and markets.
27. WASTES ACCORDING TO
GENERATION
• INDUSTRIAL WASTES
• Liquid and solid waste that are
generated by manufacturing and
processing units of various industries
like chemical, petroleum, coal, metal,
sanitary and papers.
28. WASTES ACCORDING TO
GENERATION
• INDUSTRIAL WASTES
• Non- Hazardous Waste
• Substances are safe to use
• These waste produced from food,
processing plants, cotton mills, paper
mills, and textile industries.
29. WASTES ACCORDING TO
GENERATION
• INDUSTRIAL WASTES
• Hazardous Waste
• Substances are unsafe to use
• Generated by nearly every industry.
30. WASTES ACCORDING TO
GENERATION
• INDUSTRIAL WASTES
• Metals, chemicals, drugs, lather, dye,
rubber are some examples. Liquid
industrial waste that runs into a
stream from a factory can kill
aquatic fauna and also cause death
for humans.
31. WASTES ACCORDING TO
GENERATION
• COMMERCIAL WASTES
• Mining
• The waste generated by mining
activities disturb the physical,
chemical and biological features of
the land atmosphere.
32. Classification of Waste
• In general, the waste are classifies on the basis of
their biological, chemical and physical properties
also on the basis of nature.
Biodegradable Wastes
Non- Biodegradable Wastes
Hazardous Wastes
Non-Hazardous Waste
34. Classification of Waste
Hazardous Wastes
dangerous or capable of having a harmful
effect on human health or the environment.”.
Non-Hazardous Wastes
Substances safe to use commercially,
industrially, agriculturally, and economically.
These substances usually create disposal
problems.
35. WASTES ACCORDING TO
GENERATION
• AGRICULTURAL WASTES
• Waste generated from farming
activities. These substances are mostly
biodegradable.
36. WASTES ACCORDING TO
GENERATION
• FISHERY WASTES
• Waste generated due to
fishery activities like fish
viscera,
• fish bones, and scales.
• These are extensively
found in coastal and estuaries
areas.
37. WASTES ACCORDING TO
GENERATION
• RADIOACTIVE WASTES
•Waste containing radioactive
materials. These are commonly by-
products of nuclear processes.
38. WASTES ACCORDING TO
GENERATION
• E- WASTES-Electronic wastes
generated from any modern
establishments. They may be
described as discarded electrical or
electronic devices. Some electronic
scrap components such as CRTs
may contain contaminants such as
lead, cadmium, and beryllium or
brominated flame retardants.
39. WASTES ACCORDING TO
GENERATION
• BIOMEDICAL WASTES
• Solid or liquid wastes
including containers,
intermediate or end
products generated during
diagnosis, treatment, and
research activities of
medical sciences.
40. • Several wastes disposal practices
in the country include
concentration and contain or
also known as isolation
specifically for solid waste.
Landfills and dumps minimize
the impact of waste in the
environment.
41. • Landfills is a place to
dispose waste material by
burying or covering over
with soil and becoming an
extending usable land after a
few years.
42. • Dump is an excavated piece of
land or waste storage and
regulated by the government.
• Smaller than landfill
• Other useful options are
composting, resource recovery
and energy recovery.
43. • As a grade 11 student, what do you
think are your ways to lessen wastes
in your community?
44. THE 3 Rs of WASTE MANAGEMENT
REDUCE REUSE RECYCLE
The best way to
mange waste is
not to produce it.
Avoid disposable
goods e.g. Paper,
plates, napkins,
razors and
lighters
Avoid over-
packaged goods
e.g. foil, paper,
and plastics
It makes economic
and environmental
sense to reuse
products:
Reuse products for
the same purpose.
A series of steps
that takes a used
material and
processes---
remanufactures
and sells it as a
new product.
45. Copy and complete the table by
classifying the types of waste
produced in the community. Refer to
the word pool. Suggest measures of
waste management under each
column. Write you answers on a
separate sheet of paper.
