2.  Discarded after primary use.
 Damaged , defective or superfluous material. Example
– rejected materials during textile manufacturing
process.

3.  Defined according to ‘modern system of waste
management’ viz
1. Municipal waste eg: household waste
2. Biomedical waste eg: clinical waste
3. Hazardous waste eg: industrial waste
4. Special hazardous waste eg: radioactive waste.

4.  Reuse : practice of using something again , whether for
original purpose eg: reusing shopping bags or to fulfill
a different function eg: reusing coffee grounds for pest
control.
 Recycle : breaking down of used items to make raw
materials for manufacture of new products. Eg :
production of fertilizer from industrial waste.

5.  It helps protect the environment by reducing air , land , soil
and water pollution.
 It conserves natural resources which are already massively
depleted.
 It saves energy. Recycling and composting saved more than
1.3 quadrillion Btu of energy which is the equivalent of
over 229 million barrels of oil.
 It creates jobs such as collecting and sorting.

6.  In our country , waste management is governed by Ministry
of Environment, Forest and Climate change (MoEF) .
 It works together with State Pollution Control Board set up
in various states.
 Certain laws are also present in the legal setup which helps
in regulation of waste in India.
 The National Environment Policy, 2006 laid emphasis not
only on disposal of waste but also recycling and waste
treatment.
 Beside this policy various acts have also been established
such as ‘The Environment Protection Act’ , ‘Hazardous
waste rules,2008’ etc.

7.  Waste materials produced by industrial processes or
activity. Eg: chemical solvents, pigments, sludge,
metals etc.
 It has existed since the start of Industrial revolution.
 It can be classified into two types:
1. Hazardous industrial waste eg: solvents used in
cleaning or degreasing operations.
2. Non hazardous industrial waste eg: sugars, lactic
acid, bromides or carbonates.

8.  The fertilizer industry is a highly capital and energy
intensive industry in India for eg., it has a total installed
capacity of 18 MTPA (millions tones per annum) for N
& P fertilizer nutrients while their consumption is 28
MTPA.
 The nutrients are processed into formation of the
fertilizer products like urea, DAP rtc, which is also
consumed at 57 MTPA against a production capacity of
42 MTPA.

9.  Agro industrial wastes of cattle dung, vinegar,
production residue and rice straw were solid state
fermented by inoculation with Trichoderma harzianum
to produce fertilizer containing 6-phenyl-l± pyrone
(6PAP).
 Defecation sludge from sugar beet industry containing
CaCO3, organic matter, nitrogen, phosphorus,
potassium and microelements is used to produce
fertilizer.
