The word paper comes from the ancient Egyptian writing material called papyrus, which was woven from papyrus plants. Papyrus was produced as early as 3000 BCE in Egypt, and in ancient Greece and Rome. Further north, parchment or vellum, made of processed sheepskin or calfskin, replaced papyrus, as the papyrus plant requires subtropical conditions to grow.

In China, documents were written on bamboo or bamboo material, two negative sides were firstly it was heavy and difficult to transport from one place to another. Silk was sometimes used, but was normally too expensive to consider. Indeed, most of the above materials were rare and costly.

One of the Chinese court official Ts’ai Lun discovered the modern method of papermaking in AD 105; he was the first person to describe how to make paper from cotton rags. Many trace the invention of this type of papermaking to China in 150 BCE.

This idea spread slowly from China to other East Asian cultures, but even after seeing paper, others could not figure out how to make it themselves. Gidancewas required for the manufacturing process but the Chinese were reluctant to share their know-how.

But as time passed by, this know-how was first brought to Korea in 600 and from there to Japan around 610 by a Buddhist priest, Dam Jing from Goguryeo, here fibres (called bast) from the mulberry tree were used.

According to some historians, paper contributed to global cultural advancement. According to this theory, Chinese culture was less developed than the West in ancient times because bamboo, while abundant, was a clumsier writing material than papyrus. Chinese culture advanced during the Han Dynasty and preceding centuries due to the invention of paper; and Europe advanced during the Renaissance due to the introduction of paper and the printing press.

Wood continues to be the preferred source of raw material around the world, with coniferous trees (spruce, fir, pine etc) having longer and more preferable fiber over deciduous trees (eucalyptus, beech, birch etc.) Wood is debarked and processed in the chipper house of a pulp mill and made into chips or slabs before further processing.

It must be noted that paper cannot be recycled indefinitely. After 4-6 usage cycles, the fibers become short and weak and are not usable for paper making. Some virgin pulp is usually added in processes to maintain the strength and quality of fiber.

Recycling is the process of turning waste paper  into a prime product. Most recovered paper is recycled back into paper or paperboard products. With a few exceptions, recovered paper is recycled into a grade similar or lower quality than the original.

THE BENEFITS:

Power & Water Conservation: Every ton of recycled paper saves 30,000 litres of water and 3000-4000 kwh of energy

Emissions: Recycled paper produces 28% less emissions to the atmosphere since it is not usually re-bleached with chlorine. Modern bleaching in recycling plants uses oxygen which is less polluting.

Bio-Degradable: Paper degrades when in a landfill, releasing methane into the atmosphere. Methane is a common greenhouse gas. Recycling is much safer to it.

The market for waste paper has created several common grades which are actively traded between packers and traders and sold to paper mills.

The world market for waste paper has resulted in the creation of some common recyclable grades which are used by paper mills all over the world. The business of recovered paper is a mature industry in North America, Western Europe, Japan, Singapore and Australia. These countries are net exporters of waste paper. The major importers of this waste paper are China, Indonesia, Taiwan and India. Indigenous waste paper recovery in these countries is still in the nascent stage.

Today the economic and environmental benefits from paper recycling portrays a great oppurtunity to grow into a fast growing industry worldwide. Paper is made pre-dominantly from trees. However it is a common misconception that using less paper or recycling paper will save trees. Trees which are used to make paper are grown as a crop in a sustainable basis all over the world. Every stage of the process, from the tree farms till the paper mill is built on principles of economic and ecological sustainability.
