Rubbish
It really is a good idea to put rubbish into different containers if
there is a recycling service in your town or city. Recycling saves
energy and natural resources, and it reduces the amount of
rubbish that goes into landfill. For example, all your food waste
should be separated as this can be recycled to produce electricity
or fertilizer. For glass, this can be recycled many times. This saves
using natural resources and energy to make new glass.
There are very few things we can't recycle. Glass, paper, food,
cardboard and metal are all OK. Tetra Pak are trickier because they
are made from various materials which are difficult to recycle. PET
bottle recycling is complicated, too. It's expensive, but possible.
Clothes are in a different category because they can be reused
rather than recycled. They just need to be washed and given to
somewhere like a charity. And lastly, shopping bags. These are
mainly made of plastic and can't be recycled. The best thing is to
reuse your own bag.
It's good to wash certain items as it makes it easier for them to be
recycled and it also reduces the problem of smell. The two types of
rubbish you can wash fairly easily at home are glass items, like
bottles and jars, and PET bottles. It's a good idea to wash drink
cans, too.
One way to reduce the amount of rubbish we produce is to be
careful what you buy. For example, we waste a lot of food because
we don't plan our meals properly or just buy something because it
looks tasty. We should cut back on the amount we buy and eat
everything we do buy! It's simple, really.
