WHAT IS WASTE?
Waste includes all items that people no longer have
any use for, which they either intend to get rid of or
have already discarded. Additionally, wastes are such
items which people are require to discard, for exampleby lay because of their hazardous properties. Many
items can be considered as waste e.g., household
rubbish, sewage sludge, wastes from manufacturing
activities, packaging items, discarded cars, oldtelevisions, garden waste, old paint containers etc.
Thus all our daily activities can give rise to a large
variety of different wastes arising from different
sources.

India is the second most populous country, which has about 16%
of the world population and 25% of the land area.
Rapid industrialization last few decades led to depletion of
pollution of precious natural.
Rapid industrial developments also led to the generation of huge
quantities of hazardous wastes, which aggravated the
environmental problems in the country by depleting and
polluting natural resources.
Rational and sustainable utilization of natural resources and itsprotection from toxic releases is vital for sustainable socio-
economic development.
Hazardous waste management is a new concept for most of the
Asian countries including India. The lack of technical andfinancial resources and the regulatory control for the
management of hazardous wastes in the past had led to the
unscientific disposal of hazardous wastes in India, which posed
serious risks to human, animal and plant life.

What is Recycling ?
The practice of collecting the waste materials into the
new useable products. This process prevents thewaste of useful materials. Recycling is the process of
re using the given products and producing the new
products from. It means that it is the process where
old goods are re manufactured and transformed intothe new usable products
Recycling is the process that involves the techniques
for creating new materials with the help of wastes and
used stuff .the main reason for the recycling is to
potentially decrease the inhabitants and
environmental pollution.

.
Different types of paper that can be
recycled
Cardboard/Paperboard
It is clean card board that can be recycled. It is high qualityand durable material due to which it being recycled into
paperboard but make sure that these cardboards are emptyand dry.
Newspaper recycling
Newspaper recycling involves the recycling of newspaper tocreate the new newspapers and paper products. The mainthing kept in mind while newspaper recycling is thatnewspaper does not contain any other material such as paint
over it and rubber bands rapped around

Types of Recycled Plastic
There are several types of petroleum that is refined andrecycled for obtaining the seven types of plastic resin fromdifferent type of petroleum each with the different propertiesand quality.
There are seven types of plastic resin:
1. Polyethylene Terephthalate (PET),
2. High Density Polyethylene (HDPE),
3. Polyvinyl Chloride (PVC), 4. Low Density Polyethylene (LDPE),
5. Polystyrene (PS)
6. and Other (usually a composite of several previously
mentioned)

Recycling Steel, Glass, Aluminium
Cans, and Foil
Glass, steel, copper, aluminium cans, andother metals are easily recognizable and quiteeasy to recycle.
glass bottles must not be mixed with any othertype of glass like light bulbs, Pyrex plates, glasstableware, auto glass, and window glass.
Aluminium cans should be cleaned just enough toprevent odours and it is no longer necessary to
remove labels for processing. The high heat usedin glass and metal reprocessing is enough to takecare of the problem of contamination.

Recycle Electronics or E-Recycling
Exporting Our Dirty Problem: USA exports its e-
wasted to countries like India, Pakistan and China
The Process:
breaking down the equipment into its componentparts
parts are then recycled through various methods
depending on the material Metals, plastics, and glass.

Recycling Water or Reclaim Water
Water recycling is reusing treated wastewater forbeneficial purposes such as agricultural andlandscape irrigation, industrial processes, toilet
flushing, and replenishing a ground water basin Water recycling offers resource and financial
savings
Gray water: is re-useable wastewater from
residential, commercial and industrial bathroomsinks, bath tub shower drains, and clotheswashing equipment drains

Gray water is reused onsite, typically for landscape irrigation.
Uses for Recycled Water
agriculture
landscape
public parks
golf course irrigation
cooling water for power plants and oil refineries
processing water for mills, plants
toilet flushing
dust control,
construction activities
concrete mixing
artificial lakes

Disadvantages or recycling waste watera) Requires separate factory setups for the recycling process, which results in
more energy consumption and extra cost, transportation and sorting and
cleaning as well as storage expenses
b) Big truck and big dumpers on the traffic roads irritates the traffic flow. They
collect garbage form different places and interrupt the traffic sequences.
c) Pollutants are generated even in recycling process which itself has chemicalskews involved
d) Recycling is not at all cost effective process.
e) The poor quality items cannot be recycled are dumped in rivers, and big holes
which results in the poisonous affect in the form of contaminated water
resources for the poor maintenance of recycling process are still limited ,
recycling installations also required big land area which becomes infertile

Advantages of recyclinga. Recycling minimizes the use of glass.
b. Helps in increasing the production of plastic and
paper.
c. Removes pollution in the form of garbage
recycling.
d. Creates awareness in the people for saving their
environment.
e. It minimizes the use of natural resources.
f. Avoid pollutants from interfering the natural
processes

Disadvantages of Recycling
Separate factories must be set up for the
recycling of materials (pollution, energy
consumption)
Some recycling is not cost-efficient and
annually results in a net loss
in the process of recycling papers and
plastics, harsh chemicals are used that can
cause health problems on exposure
