You should spend about 20 minutes on Questions 30-41 which are bad on the Reading Passage below.
PAPER RECYCLING
A Paper is different from other waste produce becau it comes from a sustainable resource: trees. Unlike the minerals and oil ud to make plastics and metals, trees are replaceable. Paper is also biodegradable, so it does not po as much threat to the environment when it is discarded. While 45 out of every 100 tonnes of wood fibre ud 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 worl照例的反义词是什么
dwide 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 ud fibre. As a result, industry’s u of recycled fibres is expected to increa at twice the rate of virgin fibre over the coming years.
B Already, waste paper constitutes 70% of paper ud 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 parated 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-u. The 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 houholds which discard newspapers and packaging material. The paper manufacturer pays a price for the paper and may also incur the collection cost.直接报价
D Once collected, the paper has to be sorted by hand by people trained to recogni various types of paper. This is necessary becau 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 ud to remove other materials from the stock. After passing through the repulping process, the fibres fro
湖南哪里好玩m printed waste paper are grey in colour becau the printing ink has soaked into the individual fibres. This recycled material can only be ud 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 u 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 dispod of safely. Nevertheless, paper recyc
ling is an important economical and environmental practice but one which must be carried out in a rational and viable manner for it to be uful to both industry and the community.
