Recently, researchers have reported on new ways to break down different kinds of plastics. The new studies could lead to easier high-quality (高质量的) recycling, and help deal with toxic (有毒的) plastic pollution.The world is being covered by plastic, but only about 9% of plastic product...
根据第五段About 63.5 billion kilograms of PET plastic is produced every year.可知每年要生产六千三百五十亿公斤的PET塑料。 本题正确答案为:B。 2. 答案: C 分析: 细节理解题。根据第四段Bacteria use enzymes to cause chemical changes.可知细菌用酶来产生化学反应。 本题正确答案为:C。 3. 答案: C ...
Laser-Induced Breakdown Spectroscopy (LIBS) was applied for the identification of various kinds of plastics for management and recycling of plastic waste. In order to fingerprint these plastics, a laser-produced plasma emission was recorded for spectral analysis of various kinds of plastics. The ...

A tubular free-fall separator for the electrostatic separation of particles of a plastics mixture, includes two parallel opposite rows of vertical tubes which are either arranged rotatably around their own axis or are fixedly installed and are connected with a direct current voltage source for maint...
The other kind is Halomonas Boliviensis(利维亚盐单胞菌), which lives in the salty waters of Bolivia. It eats the sugar that the first bacterium produces and then it can produce polymers(聚合物). Polymers are used to create bio-plastics. The way the bacteria store polymers is similar as ...
According to Newsweek.One of the bacteria can use sunlight to produce sugar. The other land eats the sugar and produces polymers(聚合物). Polymers are used to create bio-plastics. The way the bacteria store polymers is similar as humans store fats.The new way to produce bio-plastic has ...
The experiments of sewage sludge( SS) co-pyrolysis with four kinds of plastics( PE,PP,PS and PVC) were carried out in a high temperature tubular furnace to obtain four kinds of biochar( SSCPE,SSCPP,SSCPSand SSCPVC),respectively. The contents,residual rates,BCR speciation,leaching toxicity ...
根据文章第一段Plastics can take hundreds of years to break down on their own.Very few kinds are highly recyclable.This is because of the way plastics are formed. (塑料需要几百年才能自行分解。高度可回收利用的品种非常少。这是因为塑料形成的方式。)可知,塑料很难分解是因为塑料形成...
By: Johan Larson The renewable feature of crops causes some people to refer to them as sustainable, because they can be repeatedly grown and harvested. By: gavran333 While some plastics may be recyclable, they are not considered sustainable. ...
