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.
i. Process of paper recycling
ii. Less threat of waste paper to the environment
iii. Collection of paper for recycling

I. Read the following passage and choose the best answer.
Before the invention of plastic: Before plastic, the only materials that could be molded into different shapes were clay and glass. However, both of these materials are heavy and break easily. This is why plastic was a big improvement.
Today, plastic is used in almost everything, from shopping bags and bottles to chairs and cars. Plastic has conquered the world. But do you know how it was first made?
1862 - Parkesine
The first man-made plastic was created by Alexander Parkes, who introduced it at the 1862 Great International Exhibition in London. It was called Parkesine, and it was made from plant materials. Once heated, it could be molded, and it held its shape when cooled. Also, it could be made colored or transparent. However, it was too expensive to produce for common use.
1866 - Celluloid
In the 19th century, billiards was so popular that a lot of elephants were being killed for their ivory, which was used to make billiard balls. So, people tried to find a substitute. A U.S. billiard ball company offered a prize of $10,000 to the person who could design the best substitute for natural ivory. In 1866, John Wesley Hyatt created Celluloid while trying to win the prize. Although he failed to win, Celluloid was later used to make many products, including false teeth, piano keys, and ping pong balls.
1909 - Bakelite
Leo Baekeland created Bakelite in 1909. Made entirely of artificial materials, it was the first true plastic. It was inexpensive, and it kept its shape when heated. Soon, it was being used in many things, including electrical products and jewelry. Since then, many other plastics have been developed.
Today - Petroleum
Today, most plastics are produced from non-natural materials made from petroleum. They are light, flexible, strong, and cheap. Despite all these advantages, there is one problem: plastic waste breaks down slowly and toxic chemicals can leak from it. Therefore, people are trying to develop less harmful plastics.
1. What is the main idea of this passage?
A. Plastic is harmful to many plants and crops.
B. New materials are currently being created to replace plastic.
C. Plastic was originally invented as a substitute for petroleum.
D. Plastic has been developed and improved over a long period of time.
2. Which item was NOT made with Celluloid?
A. ping pong balls B. billiard balls C. false teeth D. piano keys
3. Which was an advantage of Bakelite?
A. It broke down very slowly. B. It didn’t contain any chemicals.
C. It could be used to store petroleum. D. It could be heated without changing shape.
4. What can be inferred about Parkesine?
A. It wasn’t as strong as ivory. B. It could not be seen through.
C. It cost more to make than Bakelite. D. It was named after a billiard ball company.
5. Which can replace the word “produce” in line 8?
A. discover B. analyze B. introduce D. manufacture
These materials can be recycled into other packaging products.
These materials can be recycled.into other packaging products.
