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

,manufacturing industries.
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.
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
