①The emergence of de-inking printers represents an advancement of printing technology and paper recycling, addressing one of the most pressing environmental challenges of our time. For decades, conventional printing processes have been linked to substantial paper waste, with millions of tons of paper being consumed annually—often used just once before being thrown away.
②The innovative de-inking printer operates through a combination of advanced technologies. Using an advanced sensor system, it first identifies the presence of ink on the surface of the paper. Subsequently, a high-intensity laser(激光) is precisely directed to target and vaporize(汽化) ink effectively, removing them without causing any damage to the paper fibers.
③One of the most remarkable advantages of this technology lies in its potential to reduce overall paper consumption. By enabling the reuse of printed materials through effective ink removal, it significantly reduces the demand for newly produced paper.This shift not only preserves natural resources but also plays a crucial role in reducing carbon emissions associated with the paper production.
④From an economic perspective, the adoption of de-inking printers presents long-term financial advantages. Although the initial investment in purchasing and installing the printer may be relatively high, the long-term savings from reduced paper and ink purchases can be substantial.
⑤However, the widespread adoption of de-inking printers is not without its challenges. The technology requires further improvements to enhance de-inking efficiency and ensure that the quality of recycled paper meets industry standards. Additionally, there exists a significant barrier in terms of user acceptance: many individuals and organizations remain accustomed to using new paper and may be reluctant to recycled alternatives, even when they are of comparable quality.
⑥In conclusion, the de-inking printer stands as a ray of hope for achieving a more sustainable future within the printing industry. With continued technological advancements and growing environmental awareness, this technology has the potential to transform the industry, contributing to a more eco-friendly and resource-efficient world.

Practice
①While new, highly-effective weight-loss drugs have hit the market, their price label and numerous side effects mean other weight-loss interventions are still needed.
②To that end, Yue Wu at Sichuan University in China and her colleagues developed microbeads (微珠) that trap fat before it is absorbed by the body. They created the beads from vitamin E and compounds (化合物) found in green tea, then coated them with alginate, a type of seaweed fibre. They are all food-grade substances approved by the US Food and Drug Administration (FDA).
③Once into the stomach, the protective alginate layer expands, allowing partially-digested fats to enter the inside of the beads, where they are attached to the compounds within. The beads along with the trapped fat are then discharged.
④The team tested the beads in eight rats fed a diet of 60 per cent fat. After 30 days, the rats lost about 17 per cent of their body weight on average. In comparison, a separate group of eight rats fed the same high-fat diet without the beads didn't lose weight, and neither did another bead-free group kept on a diet of 10 percent fat. The rats treated with the microbeads also had less fat tissue and body damage than the others.
⑤The researchers also tested body waste from rats fed the microbeads. Their waste contained roughly as much fat as that of a fourth group of rats treated with orlistat, a weight-loss drug that prevents fat absorption. This indicates the microbeads blocked fat uptake, like the drug does. Yet unlike orlistat, the beads didn't cause any side effects in the stomach.
⑥These microbeads could, therefore, be an appealing alternative. A clinical trial involving 26 people is already under way. “Initial data may become available within the next year,” said Wu in a press release.
⑦The researchers foresee adding the flavourless beads, which can be shaped into balls, to desserts and teas. “We want to develop something that works with how people normally eat and live,” said Wu.
