This document discusses different types of waste including solid waste, biodegradable waste, liquid waste, sewage waste, and others. It notes that solid waste comes from household, commercial, agricultural, and industrial sources. If solid waste is not properly collected and disposed of, it can create sanitary issues and lead to disease outbreaks. Biodegradable waste can be recycled. Liquid wastes include wastewater, oils, and other hazardous household liquids. The document also provides statistics on waste generation and disposal in India. It discusses factors that influence waste composition and how composition varies between low and high income countries.

3.  SOLID WASTE
 BIODEGRADABLE WASTE
 LIQUID WASTE
 SEOUS WASTE
 ANIMAL BY PRODUCT
 COMMERICAL WASTE
 BIOMEDICAL WASTE
 CHEMICAL WASTE

4. Solid waste
 It is defined as
non –liquid ,non soluble ranging form
municipal garbage to industrial waste that contain complex and
sometimes hazardous substance.
 Source
 household
 Fishers
 Commerce &industry
 agriculture

5. Waste

,junk) is any unwanted or useless material.
Or
any material unused and rejected “ as
worthless or unwanted ” and a useless or
profile less activity using or expanding on
consumers thoughtlessly or carefully.

6. Effects of solid waste
If solid waste not collected and allow to acculamate,
they may create sanitary conditions.
This may leads to epidemic outbreaks.
Many diseases like chorea, diarrhea, plague, jaundice
inessential diseases may spread and cause loss of
human lives.

7. Biodegradable waste

8. RECYCLING
• Recycling refers to the collection and
refuse of waste material such as empty
beverage container,
• The material from which the items are
made can be processed into new
products.
• Materials for recycling may be collected
separately from general waste using
dedicated bins.

9. Liquid wastes
 liquid wastes can be defined as
such as fluids as wastewater ,
fats , oil , or grease and
hazardous household liquid to
name a few.
Examples : domestic washings,
waste water pounds, oils
,manufacturing industries.

10. waste in India
 7.2 million tones of hazardous waste.
 One sq. km of additional landfill area every-year
 Rs. 1600 crores of waste & disposal of these
wastes.
 In addition of this industries discharge about 150
million tones of high volume of low hazard
waste every year , which is mostly dumped on
open low lying land areas.

11. Composition of wastes
I. Waste composition is influenced by factors such as culture,
economic development ,climate and energy sources ; composition
often waste is collected is collected and how to disposed.
II. Low income countries have the highest proportion of organic
waste.
III. Paper , plastic , and other inorganic materials make up the highest
proportion of organic wastes at 62% while OECD countries have
the least at 27%, although total amount of organic waste is still
highest in OECD countries.
IV. Although waste composition is usually provided by weight, as a
country’s affluence increases, waste volumes tend to be more
important, especially with regard to collection: organics and inserts
generally decrease in relative terms, while increasing paper and
plastic increases
