Fashion brand JUMA recently showed its newest collection at a workshop in Shanghai. Eighteen clothing items from the collection, including jumpsuits, jackets, shirts and dresses, were made from recycled plastic bottles. “We realized that billions of water bottles are being thrown into landfills and the ocean every year and that these bottles take hundreds of years to decompose(分解). We thought we should use them to create our clothes and help the environment，” said Alia Juma, the company's design director. Many other fashion companies are finding similar ways to save our planet these days. The process is rather simple. First, the plastic bottles are washed and cut into small pieces. Then they are melted and shaped into small balls. The balls are melted again to form thread(线). People can then use the thread to make different kinds of clothes. According to Juma, it takes 67，000 bottles to create 1 ton of thread. This reduces carbon emission(排放) by 4.2 tons and water use by 6.2 tons compared with the normal way of making thread. “Five bottles can make one pillowcase. Five can make a shirt, 10 a dress and 20 a short coat，”Juma said. Some people might have doubts about wearing something made out of plastic bottles. But it is reported by Causeartist, a website that focuses on creativity, that the quality of the clothes from plastic bottles could be even better than nylon and polyester. Plastic thread can be made into different textures, such as cotton, silk or even wool. It seems that this may lead into a greener future of fashion.
