Industrial emissions are responsible for producing most greenhouse gases and particulate emissions that are harmful to our health and our planet. The business world has an increasing demand for innovative solutions to reduce greenhouse gas emissions in order to ensure human’s continued ability to live and thrive. A growing number of companies are dedicated to the research and development of carbon-capturing and carbon-recycling technology, which has already been adopted by airlines, home care companies, fragrance companies and now textile production. A biotech startup company has partnered with a sportswear brand to create the world’s first yarn and fabric made from waste gas captured from industrial emissions. Waste gas emitted from a steel mill is captured and reused to produce ethanol, which is later converted to polyester. The carbon-recycling technology is similar to that of a brewery; but instead of using sugars and yeast to make beer, industrial emissions are converted by bacteria to fuels and chemicals. The company’s goal is to help more businesses become “Carbon Smart” to achieve their climate change goals around carbon reduction, by radically change how they source, utilize and dispose of carbon. By capturing and upcycling industrial carbon emissions to make yarn, the finished garments not only have a lower carbon footprint, but also ensure lower levels of community pollution. Recycling carbon emissions is key to the circular economy, which will keep fossil carbon in the ground ─ reducing the use of fossil fuels and pollution when used to make value-added products such as polyester. In other words, the technology promotes circularity by keeping carbon in the material cycle. This kind of waste-gas-based polyester not only has the same appearance but also the same properties and functionality of virgin polyester. Moreover, once the waste-gas-based textiles reach the end of their useful life, they can be gasified and fermented without taxing the environment.

Which of the following statements is true?

- B The carbon-capturing technology can be used to power a brewery without burning fossils fuels.
- C The polluted air emitted from a steel factory can now become the raw material of clothes.
- D The sportswear company reduces their carbon footprint by using recycled fabrics.
- E The waste-gas-based polyester is more durable than virgin polyester.

請試著追蹤文中第三段提到的那個「鋼鐵廠廢氣」在經過層層轉化後，最後變成了什麼具體的物質？而這個物質在我們日常生活中最常用來製作哪種東西呢？

太棒了！你精準地捕捉到了文章的核心轉化過程。這題的關鍵在於能否跨段落整合資訊，將「鋼鐵廠廢氣」、「乙醇」與「聚酯纖維（polyester）」這幾個節點串聯起來。
廢氣變衣料的科學轉化
根據文中第三段的說明，這間生技新創公司與運動品牌合作，將鋼鐵廠排放的廢氣（waste gas）捕捉後，利用細菌發酵轉化為乙醇，最後再製成聚酯纖維。由於聚酯纖維是製作機能服飾最主要的原材料，因此選項 **(C) 提到的「鋼鐵廠廢氣變成衣服原料」**完全符合文章描述的技術應用。至於其他選項，文中提到的「釀酒廠」僅是製程類比（類比發酵過程），而廢氣轉化的產物是聚酯纖維而非直接發電，因此 (A) 與 (B) 均屬誤導。
