Recycling & Waste Management
1.
2. Recycling
Recycling is a process to change waste materials into
new products to prevent the wastage of potentially
useful materials, reduce the consumption of fresh
raw materials, reduce energy usage, reduce air
pollution and water pollution by reducing the waste
disposal.
Recycling is an useful key component of modern
waste reduction system.
4. Recyclable solid waste materials include
different types of solid materials such as
glass, paper, metal, plastic,
polyeteline, textiles etc.
Although similar in effect, the reuse or
the composting of biodegradable
(organic) wastes such as food or garden
waste is not typically considered
recycling.
5. Different types of solid waste can be found from textile and garments
industries. Piece of cloths, unused yarn, broken buttons and other utilities
are among them. These things can not be used in garments making but they
can be used in other ways. As for example, Garments Cotton is the type of
cotton which is made by the waste fabrics and yarns torne or cut in small
length.
6. Plastic is a such element that does not reacts
with natural components anyway so that that
harms much to the environment. It reduces
soil fartility, obstacles the water flow, even
sometimes increases deseases. So recycling
plastic materials is the only way to reduce the
pollution created by it.
7. The process of recycling plastics as Polyethylene
Terephthalate(PET), Polyvinyl Chloride(PVC),
Polypropiline(PP), Polystyrene(PP) and others are:
Collecting
Washing
Melting
Refining
Producing recycled product
PET is known as the food grade plastic. So it needs
to be sanitized and non harmful for human use after
recycling.
8. There are several types of metals we use in our daily life. Among
them we use iron (steel), aluminium, coppar mostly. Here the
recycling process of aluminium is given.
9. Glass recycling is the process of turning waste
glass into usable products. Glass waste should
be separated by chemical composition,
depending on the end use and local processing
capabilities, might also have to be separated
into different colors. Many recyclers collect
different colors of glass separately since glass
retains its color after recycling. Glass is a brittle
substance and in broken state it is so sharp to
cut human or animel skin.
10. Waste glasses Taken to treatment plant Washed properly
Crushed & melted Re-produced glsses Ready to use & recycle
11. After use, the waste papers such as Newspspers, Books,
Writing pads, Packing papers etc are collected and others
stored. Then they are taken to the recycling industries and
then they are passed through several processes to make
them re useable in same or different ways.
The things which can be made by recycled papers are:
Newsprint Papers
Envelops
Paper Bags
Boxes
Hard boards
