Original: In the reading, it discusses the concept of closed-loop design, which means some products are made of sustainable materials, and when they reach their end of life, they will be collected by the company and converted back to new products, and in the lecture, the professor takes carpet as an example. In the conventional times, carpet was ripped out and thrown away and they end up in the garbage. However, nowadays, some innovative companies reuse the carpet. They took the top layer and clean and dye the worn-out carpet and put them into producing new carpet. In this way, they can reuse the raw materials and can save the company a lot of money and preserve the environment at the same time. Compared to burning it down, it can be so eco-friendly.

Revised (140 words): The concept of closed-loop design is discussed in the reading, which involves creating products from sustainable materials that can be collected and converted back into new products when they reach their end of life. In the lecture, the professor uses carpet as an example to illustrate this concept. In conventional practices, carpets were ripped out, thrown away, and ended up in landfills. However, some innovative companies now reuse carpets by taking the top layer, cleaning and dyeing the worn-out fibers, and incorporating them into new carpet production. This approach allows for the reuse of raw materials, saving companies money while preserving the environment simultaneously. Compared to traditional disposal methods like burning or dumping in landfills, closed-loop design is much more eco-friendly.
