Aboutwaste
The word "rubbish" is a noun that refers to garbage or refuse
or any other waste, trash or junk. Any thing worthless can also be referred to
as rubbish. Rubbish also means a foolish discourse or any nonsense that one is
talking or speaking. Rubbish can also be used as a verb to refer to disclaiming
what another is saying. The word is derived from the Middle English word
"robishe".
Rubbish in its sense as waste can be in solid,
liquid or gaseous states. Rubbish is generally discarded by every individual,
family, community and municipality. Several forms of rubbish like plastics,
glass and scrap metal can be recycled and in various other forms of household rubbish can be composted and mixed with the soil
once again. Rubbish can also be burnt in incinerators and electricity
harnessed.

:
Reduce,
reuse, recycle
We all produce
rubbish. Usually we don’t think about it. We just throw it away. But the world
is running out of room to store all the rubbish that is piling up. If left
lying around, rubbish becomes a health hazard and looks ugly. Burning rubbish
pollutes the air and the ashes are often toxic. Sometimes rubbish is dumped
into rivers and lakes and pollutes the water. Often rubbish is buried in the
ground. Buried rubbish may contain toxic substances that leak into the soil and
pollute the water supply. There are three things we can do to limit the impact
of rubbish on the environment :
·
Reduce.
The best
solution is to reduce the rubbish we make in the first place. For example, we
should only buy products that do not have much packaging and that we really
need.
Think
carefully about what kinds of materials are used in the things we buy. Once
they become rubbish, they might take a long time to decay.
Plastics, there are
nearly 50 kinds of plastics commonly used to make everything from juice
containers and rubbish bags to windows and doors. Many plastics are strong and
durable. They won’t rot, decay or dissolve. However, making plastic uses a lot
of energy. Many plastic products cannot be used again, so we throw them out.
The problem with plastic rubbish is that it turns into poisonous products.
For example,
vinyl, which is used to make bottles, car parts and pens, pollutes the soil if
it is buried and releases poisonous substances into the air if it is burned. We
should try to reduce the amount of plastics that we use. However, some plastics
can be recycled to make hair combs, floor tiles and polyester clothing.
· Reuse
People are often very imaginative in reusing items, rather than throwing them away. For example, we can flatten empty aluminium cans and use them as sheet metal. We can make furniture out of scrap wood and use well-washed glass jars to store foods, carpentry and office supplies. More examples are given on pages 8–9 in this issue of Footsteps.

· Recycle
If items such as glass bottles, metal and tin cans, newspapers and plastics cannot be reused, it may be possible for them to be recycled. For example, glass is washed in special factories, broken into pieces and then melted down into ‘new’ glass ready to be made into something else. Some countries have factories that will recycle these materials.
