PAPER RECYCLINGA Paper is different from other waste produce because it comes from a sustainable resource: trees. Unlike the minerals and oil used to make plastics and metals, trees are replaceable. Paper is also biodegradable, so it does not pose as much threat to the environment when it is discarded. While 45 out of every 100 tonnes of wood fibre used to make paper in Australia comes from waste paper, the rest comes directly from virgin fibre from forests and plantations. By world standards, this is a good performance since the worldwide average is 33 percent waste paper. Governments have encouraged waste paper collection and sorting schemes and at the same time, the paper industry has responded by developing new recycling technologies that have paved the way for even greater utilization of used fibre. As a result, industry’s use of recycled fibres is expected to increase at twice the rate of virgin fibre over the coming years.
B Already, waste paper constitutes 70% of paper used for packaging and advances in the technology required to remove ink from the paper have allowed a higher recycled content in newsprint and writing paper. To achieve the benefits of recycling, the community must also contribute. We need to accept a change in the quality of paper products; for example, stationery may be less white and of a rougher texture. There also needs to support from the community for waste paper collection programs. Not only do we need to make the paper available to collectors but it also needs to be separated into different types and sorted from contaminants such as staples, paperclips, string and other miscellaneous items.
C There are technical limitations to the amount of paper which can be recycled and some paper products cannot be collected for re-use. These include paper in the form of books and permanent records, photographic paper and paper which is badly contaminated. The four most common sources of paper for recycling are factories and retail stores which gather large amounts of packaging material in which goods are delivered, also offices which have unwanted business documents and computer output, paper converters and printers and lastly households which discard newspapers and packaging material. The paper manufacturer pays a price for the paper and may also incur the collection cost.
D Once collected, the paper has to be sorted by hand by people trained to recognise various types of paper. This is necessary because some types of paper can only be made from particular kinds of recycled fibre. The sorted paper then has to be repulped or mixed with water and broken down into its individual fibres. This mixture is called stock and may contain a wide variety of contaminating materials, particularly if it is made from mixed waste paper which has had little sorting. Various machineries are used to remove other materials from the stock. After passing through the repulping process, the fibres from printed waste paper are grey in colour because the printing ink has soaked into the individual fibres. This recycled material can only be used in products where the grey colour does not matter, such as cardboard boxes but if the grey colour is not acceptable, the fibres must be de-inked. This involves adding chemicals such as caustic soda or other alkalis, soaps and detergents, water-hardening agents such as calcium chloride, frothing agents and bleaching agents. Before the recycled fibres can be made into paper they must be refined or treated in such a way that they bond together.
E Most paper products must contain some virgin fibre as well as recycled fibres and unlike glass, paper cannot be recycled indefinitely. Most paper is down-cycled which means that a product made from recycled paper is of an inferior quality to the original paper. Recycling paper is beneficial in that it saves some of the energy, labour and capital that go into producing virgin pulp. However, recycling requires the use of fossil fuel, a non-renewable energy source, to collect the waste paper from the community and to process it to produce new paper. And the recycling process still creates emissions which require treatment before they can be disposed of safely. Nevertheless, paper recycling is an important economical and environmental practice but one which must be carried out in a rational and viable manner for it to be useful to both industry and the community.

Marriage is an ancient religious and legal practice celebrated around the world. However, wedding customs vary from country to country.
The Wedding Dress: In many countries, it is customary for the bride to wear a white dress as a symbol of purity. The tradition of wearing a special white dress only for the wedding ceremony started around 150 years ago. Before that, most women could not afford to buy a dress that they would only wear once. Now, bridal dresses can be bought in a variety of styles. In some Asian countries and in the Middle East, colors of joy and happiness like red or orange other than white are worn by the bride or used as part of the wedding ceremony,
The Wedding Rings: In many cultures, couples exchange rings, usually made of golf or silver and worn on the third finger of the left or right hand, during the marriage ceremony. The circular shape of the ring is symbolic of the couple's eternal union. In Brazil, it is traditional to have the rings engraved with the bride's name on the groom’s ring, an vice versa.
Flowers: Flowers play an important role in most weddings. Roses are said to be the flowers of love, and because they usually bloom in June, this has become the most popular month for weddings in many countries. After the wedding ceremony, in many countries the bride throws her bouquet into a crowd of well-wishers – usually her single female friends. The person who catches this bouquet will be the next one to marry.
Gifts: In Chinese cultures, w edding guests give gifts of money to the newly-weds in small red envelopes. Money is also an appropriate gift at Korean and Japanese wedding. In many Western countries, for example in the U.K, wedding guests give the bride and groom household items that they may need for their new home. In Russia, rather than receiving gifts, the bride and groom provide gifts to their guests instead.
With the continued internationalization of the modern world, wedding customs that originated in one part of the world are crossing national boundaries and have been incorporated into marriage ceremonies in other countries.
