The Recycling Rate for Tires
In Japan, the recycling rate for tires was already 93 percent in 1993, Discarded tires are recycled here in three ways. The most familiar involves simply using them "as is"--in their original shape for such things as playground equipment in schools and public parks. They are even used in some "bullet train" tracks as shock absorbers.
Another popular use of discarded tires involves extracting rubber for processing into new products. "You can recycle rubber 100 percent, and as often as you wish. Rubber used in making tires is especially strong, so the rubber derived from scrapped(报废的)tires can be used in various ways," says Minoru Muraoka, president of Muraoka Rubber Co. who is bent on(致力于)recycling tires. In addition to being reused in tires, recycled rubber is used to make sheet rubber. Also, powdered rubber is used to make roof tries and slabs for sidewalks, thus contributing to improving the looks of our cities.
The third use for scrapped tires is as fuel. Half of all scrapped tires are currently used for this purpose at various installations requiring large amounts of heat energy.
Furthermore, Takeji Kobata, a researcher in Hokkaido has developed an epoch-making technology for making activated carbon (活性炭) by burning used tires. Activated carbon made from tires is of better quality and has greater absorptive power than other varieties already on the market. With the Kobata method, 1. 5 kilograms of activated carbon can be obtained from a single 7-kilogram automobile tire. Kobata has already obtained manufacturing patent (专利) in the United States, Canada and Taiwan, and has also opened the patented process to the public in Britain, Germany, France and Brazil

轮胎回收率
1993年，日本的轮胎回收率已达93％。在这里，废弃的轮胎以三种方式被回收再利用。最常见的一种回收利用方式是按照它们的原样——它们本来的形状——将其重新用作学校及公园的操场娱乐设施，有时这些轮胎还被用在一些“新干线’’列车的铁轨上以减少震动。
废弃轮胎的另一种常见的回收再利用方式是从它们中间提取橡胶加工成新产品。一心致力于轮胎回收再利用研究的Muraoka橡胶公司总裁Minoru Muraoka说：“你可以百分之百地、无数次地回收橡胶。用来做轮胎的橡胶韧性很强÷所以从废弃轮胎中提取出来的橡胶回收再利用的用途也就很多。”除了将提取的橡胶重新用来制造轮胎外，它还被用于制造薄片状橡胶，另外，橡胶碎料还被用来制造房瓦及人行道边板，因此也能美化我们的城市。 废弃轮胎的第三种用途是作燃料。现在，有一半的废弃轮胎被用作燃料，为那些需要大量热能的建筑设施服务。
此外，北海道的一位研究员Takeji Kobata开发了一种划时代的技术，他通过燃烧废弃轮胎制造出活性炭。这种从轮胎中制造出来的活性炭与市场中现有的其他活性炭相比，质量更好，吸收力更强。用Kobata开发的这种方法，一个重7千克的汽车轮胎可以制出1．5千克的活性炭。Kobata已在美国、加拿大和台湾获取了生产专利，并向英国、法国、德国和巴西的公众开放已经获得专利权的加工过程
