WHY IS PAPER RECYCLING NECESSARY ?

In 2003/04, paper and card accounted for almost a third of all household waste collected for recycling, with almost 1.3 million tones being collected in England. This means however that there is still a considerable amount that isn't recycled and is largely going to landfill or incineration.

Although the raw material for making paper is predominantly trees, it is a common misconception that recycling waste paper saves trees. Trees for papermaking are grown and harvested as a long-term crop with new trees planted to replace those cut down. Nearly all paper is made from wood grown in these "sustainable" forests.



The more important environmental issues are:

The nature of forests and where they are situated. As the demand for paper has increased, more timber has been needed to meet the demand for wood pulp. In some cases this has meant the loss of valuable wildlife habitats and ecosystems, as old forests have been replaced by managed plantations, usually of fast-growing conifers. The lack of tree species diversity in managed forests has a direct impact on the biodiversity of the whole forest.

By using waste paper to produce new paper disposal problems are reduced.



For every tone of paper used for recycling saves the following:


-At least 30000 liters of water

-3000-4000 kHz electricity (enough for an average 3 bedroom house for 1 year)

-95% of air pollution

-Producing recycled paper involves between 28 - 70% less energy consumption than virgin paper and uses less water. This is because most of the energy used in papermaking is the pulping needed to turn wood into paper.

-Recycled paper produces fewer polluting emissions to air (95% of air pollution) and water. Recycled paper is not usually re-bleached and where it is, oxygen rather than chlorine is usually used. This reduces the amount of dioxins, which are released into the environment as a by-product of the chlorine bleaching processes.

-Paper is a biodegradable material. This means that when it goes to landfill, as it rots, it produces methane, which is a potent greenhouse gas (20 times more potent than carbon dioxide). It is becoming increasingly accepted that global warming is a reality, and that methane and carbon dioxide emissions have to be reduced to lessen its effects.

Hey vikram,

I am also uploading a document which will give more detailed explanation on the Introduction on Recycling.
