2. WASTES
Waste are unwanted or unusable materials. Waste is
any substance which is discarded after primary use, or
is worthless, defective and of no use. A by-product by
contrast is a joint product of relatively minor
economic value.
3. Kinds of waste
Solid wastes
■ Examples:
plastics, bottles, cans, papers,
scrap iron, and other trash.
Liquid wastes
■ Examples:
domestic washings, chemicals,
oils, waste ,water from ponds,
manufacturing industries and other
sources.
4. Classification of Wastes according to
their Properties
Bio- degradable
■ Example:
paper, wood, fruits and others.
Non- degradable
■ Example:
plastics, bottles, old machines,
cans and others
6. India generates around 60 million tones of garbage every single day and almost 45
million tones , a whopping 75%, of the garbage are dumped untreated in the
landfills. Delhi and Mumbai together generate about 10 million tones of garbage
every day. If we do not reduce waste and generate it at current rate, India will need
1,240 hectares of land, which is the size of a metropolitan city like Bengaluru, to
dump country's waste. The situation is alarming and needs everyone to start taking
immediate action to deal with the garbage problem.
8. REDUCE PLASTIC
The only solution is to junk
plastic and look for alternatives.
For instance, substitute plastic
cups and plastic pens with
paper cups and vintage ink
pens respectively. Ditch plastic
straws, instead sip your drinks.
To make nine plastic bags is
takes as much as energy as
driving a car for one kilometre.
Besides, plastic bags are
harmful for the environment. So
for the next shopping
expedition, replace plastic bag
with a mesh bag that comes
with a drawstring or a cloth
bag. Denim bags are a great
way to reuse old or worn out
jeans.
9. Segregate Waste
Simply start by getting color
coated bins. Differentiate the
bins into following: Green for
organic, yellow for glass, white for
paper, grey for metal, red for
hazard and blue for plastic.
Segregate waste into two
categories – Bio-Degradable and
Non-Bio-Degradable.
Put wet wastes like leftover
foods, vegetables, peels etc. in
an organic dustbin which can
later be used for composting
Segregation of waste can reduce
the garbage burden on the
already overflowing landfills,
thereby curbing the pollution
levels.
10. ADOPT
COMPOSTING
Composting can reduce
household waste generation by
30 per cent. Composting is
also
beneficial for plant growth as
it
provides many essential
nutrients for them and it can
also be used as fertilizer. It is
believed that a family of 4 can
easily reduce their waste from
1000 Kg to less than 100 kg
every year if they adopt
segregation and composting
11. Go paperless
Papers account for almost 35 per
cent of the waste that is dumped in
landfills. From paper cups to
napkins everything ends up in
landfills from the trash can. To
reduce paper waste, start using old
clothes like rags for cleaning
around the house, instead of paper
towels. Switch to hand towels
from paper napkins in your
kitchen. Avoid using paper plates
in house parties.
12. Adopt 3R’s
Re-purposing your household
trash is a good way to reduce
waste. For example, instead of
throwing the plastic bottles use
them to decorate your house
and make other DIY plastic
showpieces. Switch to items
that can be refilled like printer
cartridges or glue, reuse plastic
folders. Use old wood and
pallets to build compost bins.
Reuse toiletries like shampoo
bottles as cell charging
stations, old toothbrushes as
cleaning tools.
