　　Narrator 1：You are now going to hear a talk about glass recycling.   Narrator 2：

　　Glass recycling is now a standard process in many towns andcities of the world.Millions of glass items are used every day,with bottles，jars and light bulbs being among the mostcommon.The process of recycling glass rather than making it new saves energy and reduces the amount of waste at landfills.

　　The first step in the process of recycling household glass is towash the items in warm,_s_9aPy water.This is to ensure thatthere isnt any drink or food left on the glass.Secondly，the jarsand bottles are collected by one of two systems，depending onthe town or city.In some places，bottles and jars are taken bythe general public to bottle banks.Bottle banks are largerecycling bins，usually with three holes that enable the glass tobe separated by colour——clear,brown or green.In other cities，people put their bottles and jars in a container which theyleave outside their house on a set day of the week.A truckthen comes past,and the glass is collected and sorted intodifferent colours by glass collection companies.

　　Thirdly,the glass is taken to a glass plant,where the actualrecycling process takes place.At the glass plant,one of twothings can happen.In the first case，the bottles are sterilizedand then reused for their original purpose that is，soft drinkbottles are refilled with soft drinks，or jam jars are refilled withjam，and so on.Reusing bottles as they are saves money，andsaves more energy than the second process.In the second case，the glass is melted down and made into new bottles or otherproducts entirely.First，all of the glass of one colour is placedinto abig crushingmachineand broken into smallpieces.Itisimportant to separate the different types and colours of glass，because they have different chemical properties.Then,thecrushed glass is mixed with amounts of sand,ash andlimestone andplacedin a furnace to be melted.

　　Finally,most of the melted glass is poured to make new bottlesand jars.However,depending on the quality,it can be used tomake other products，including floor tiles and fibreglass.

　　Narrator 1：You are going to hear a talk about the recycling processfor aluminium cans.

　　Narrator 2：

　　Every year，millions and millions of drink cans are soldaround the world.Approximately 75 per cent of these drinkcans are made of aluminium.The process of recycling thesecans is very important because it saves energy and reduces theamount of waste in landfills.

　　In the first step in the recycling process，the used cans arecollected.As with glass bottles and jars，this means that thecans are either taken by the general public to large recyclingbins-known ascan banks-outside supermarketsand othershops，or picked up from outside people’s houses by cancollection companies.Secondly，the cans are taken to specialcentres，where they are checked for any liquid,paper or othermaterials that could be a problem for the recycling process.

　　Thirdly，the cans are then transported to a recycling plant，where a machine cuts them into small pieces.Then the piecesof aluminium are melted in a very hot furnace，before beingpoured into huge moulds and left togo cold.

　　In the next stage，the big blocks of aluminium are taken toanother plant for rolling.First,they are heated and then rolledby a machine to make them thin.Next,they are left to cool，before being rolled a second time until they are thin enough tomake new aluminium cans.The thin Pieces of aluminium arethen put into another machine where they are cut up andmade into new cans.After this，the new cans are painted withthe colours and the logo of the drink company.Inthefinal stages，the cansareplacedin anoventodry，beforebeing washed.Lastly，the new，clean aluminium cans are fiUedwith gas and liquid.They are now ready to be transported toshops，supermarkets and drink machines for people to buy.Then，the recycling process begins all over again.
