Passage （A）
Around 45% of plastic waste is recycled annually in the UK and plastic waste is on the increa.However,one of the problems with prent plastic recycling methods is that you end up with a lower-quality plastic with wor properties (特性) than the original.This means that plastic drink bottles cannot simply be recycled into new drink bottles continuously,but instead are ud for other lower-grade products like park benches笑话论坛.
Now,British scientists have developed a new method of chemical recycling.They u lower temperatures and more environmentally friendly chemicals than previous methods to turn plastics back into their constituent chemical molecules (分子).In this way,they can be ud to make new plastics of the same quality as the original.
下一步工作打算
“Most plastics are now recycled using mechanical methods,where they are transformed into liquids before being made into something new,”said a professor named Matthew Jones.“The problem is,melting plastic changes its properties and reduces the quality.Our method of chemical recycling overcomes this problem.Then plastics can be ud all over again without losing any properties.”
The rearchers are recycling some kinds of plastics,including plant-bad PLA,a plastic ud for food packaging and PET,which is ud for drink bottles.So far,the technology has only been demonstrated in a small range.However,scientists are now working to produce larger quantities of chemicals信封封面格式.
“There is no single solution to the problem of plastic waste—the approach has to be a co
mbination of reducing,reusing and recycling.Our method of chemical recycling could allow carbon to be recycled endlessly rather than digging more up from the ground in the form of fossil fuels,or letting it into the atmosphere as a greenhou gas,”said Dr.Paul McKeown from the University of Bath.

Passage （B）
Imagine being a business that regularly takes huge quantities of your own products worth millions of pounds and burns them up. Your stock literally goes up in smoke. It sounds crazy, but the practice is common for some of the world’s biggest clothing manufacturers. They argue that it is the most cost-effective way of maintaining their brand’s exclusivity (独特性).
The clothes that are burned are tho that do not ll at a high enough price. Rather than watch them go on sale, the companies would t fire to them and regain a small amount of energy.
Nobody knows exactly how much unsold stock is burnt annually by tho fashion hous, but burning clothes has various negative impacts on the environment. For example, burning clothes made from artificial fibers may relea plastic microfibers into the atmosp
here, which worns global warming. A UK parliamentary committee report on sustainability and the fashion industry advis the government to ban the burning of unsold stock if it can be reud or recycled.
Actually, there are other approaches. What if tho companies had a ction tasked with taking back unsold clothes, redesigning them into new products, and shipping out the new products to the market once again?
There is also now an opportunity to focus on biodegradable (可生物降解的)fabrics. Clothes that break down faster might not have to be burned. They would also appeal to tho who care about the environmental impact of their own wardrobes.
Additionally, we have an over-production problem. According to the World Bank, while clothing sales have rin steadily since 2000, clothing utilization has fallen at roughly the same rate. For every extra T-shirt that is sold, it will be worn roughly half as much as it would have been 20 years ago. That means better forecasting market trends would in theory result in less waste.

Burning clothes won’t happen simply through fashion firms. The scale of fashion production has to change. And it’s important to recognize that the consumer-focud brands will only go where the market takes them. If protecting the environment really matters to the public, they have to make clear that they want more sustainable clothing in the first place. Without consumers demanding that, it won’t change.
