　　英语四级阅读理解100篇之电子产品回收

　　Japan is getting tough about recycling—and not inthe paper and plastic kind of way. Recently, thecountry requires that all electronic goods—TVs,VCRs, stereos, and more—be recycled. But recyclingwill not beleft to consumers, instead, the devices willbe sent to the original manufacturer for properdisposal.

　　The new law poses a few challenges to manufacturers who are now rushing to set up collectionnetworks and perfecting techniques to disassemble and recycle older products.With an eyetoward the future, they are also integrating easily recycled materials into new products.Plastics, a major component of most electronicproducts,pose a particular obstacle becausetheir quality becomes worse and worse with age,losing strengthand flexibility even ifreprocessed.NEC Corp. overcomes this problem by creating a plastics sandwich, in which thefilling is 100 percent recycled plastic and the outer layers a mixture of 14 percent recycledmaterial.The resulting plastic has sufficient strength and toughness for use as a case fordesktop PCs. The company, in cooperation with plastic maker Sumitomo Dow, has alsodeveloped a new plastic, which engineers claim retains its mechanical properties throughrepeated recycling. NEC uses the plastic, which is also flame-retardant (阻燃的) in batterycases for notebook PCs.

　　Meanwhile, Matsushita Electric, maker of the Panasonic brand, is avoiding plastic in favor ofmagnesium (镁). Magnesium, says the company, is ideal for re cycling because it retains itsoriginal strength throughrepeated reprocessing. Matsushita has developed moldingtechniques to form magnesium into the case for a 21-inch TV. Unfortunately, the magnesiumcase and energy-saving features make the TV about twice as expensive as an ordinarymodel.The company hopes, however, that increased use of magnesium will eventually bringprices down.
