1 . Live with roommates? Have friends and family around you? Chances are that if you’re looking to live a more sustainable lifestyle, not everyone around you will be ready to jump on that bandwagon.
I experienced this when I started switching to a zero waste lifestyle five years ago, as I was living with my parents, and I continue to experience this with my husband, as he is not completely zero waste like me. I’ve learned a few things along the way though, which I hope you’ll find encouraging if you’re doing your best to figure out how you can make the change in a not-always-supportive household.
Zero waste was a radical lifestyle movement a few years back. I remember showing my parents a video of Bea Johnson, sharing how cool I thought it would be to buy groceries with jars, and have so little trash! A few days later, I came back with my first jars of zero waste groceries, and my dad commented on how silly it was for me to carry jars everywhere. It came off as a bit discouraging.
Yet as the months of reducing waste continued, I did what I could that was within my own reach. I had my own bedroom, so I worked on removing things I didn’t need. Since I had my own toiletries (洗漱用品), I was able to start personalising my routine to be more sustainable. I also offered to cook every so often, so I portioned out a bit of the cupboard for my own zero waste groceries. Perhaps your household won’t entirely make the switch, but you may have some control over your own personal spaces to make the changes you desire.
As you make your lifestyle changes, you may find yourself wanting to speak up for yourself if others comment on what you’re doing, which can turn itself into a whole household debate. If you have individuals who are not on board, your words probably won’t do much and can often leave you feeling more discouraged.

3 . People have come to understand the enormous impacts-beneficial as well as harmful- plastics have on human lives and the environment. As polymer (聚合物) scientists committed to inventing sustainable solutions for real-world problems, we set out to tackle the issue of plastic waste by rethinking the way polymers are designed so we could make plastics with recyclability built right in.
Everyday items including milk jug, grocery bags, and takeout containers are made from a class of polymers called polyolefins. These plastics are really durable (耐用的) because the chemical bonds in those polymers are extremely stable. In a world set up for disposable (一次性的) items, durability is no longer a design feature but rather a design drawback. Imagine if half the plastics used today were recyclable through twice as many processes as they are now. Also conventional recycling requires careful sorting of all the collected materials, which can be challenging with so many different plastics. For example, separating paper from metal doesn’t require complex technology, but sorting a container from a milk jug of a different polyolefin is difficult to do without the occasional mistake.
In a study published in Science in October 2023, we described a series of polymers with only two building blocks-one soft polymer and one hard polymer-that behave like polyolefins but could be chemically recycled. Connecting two different polymers multiple times until they form a single, long molecule (分子) creates what’s called a multiblock polymer. By changing how much of each polymer type goes into the multiblock polymer, our team produced a wide range of materials with properties that covered all polyolefin types.
Using the same strategy but by adding hydrogen, we could disconnect the polymers back into their building blocks and easily separate them to use again. When we made new polymers out of these recycled plastics, they performed just as well as the original materials even after several rounds of chemical recycling. So we were able to create materials with similar properties of the plastics the world relies on. We believe this work is a step toward more sustainable plastics.

4 . With an abundance of sun and wind, Spain is positioning itself as Europe’s future leader in green hydrogen production to clean up heavy industries. But some energy experts express caution because this process relies on massive availability of zero-carbon electricity.
Green hydrogen is created when renewable energy sources power an electrical current that runs through water, separating its hydrogen and oxygen molecules (分子). The process doesn’t produce planet-warming carbon dioxide, but less than 0.1% of global hydrogen production is currently created in this way.
The separated hydrogen can be used in the production of steel, ammonia (氨) and chemical products, all of which require industrial processes that are harder to stop fossil fuels. Hydrogen also can be used as a transportation fuel, which could one day transform the highly polluting shipping and aviation sectors.
Spain’s large, windswept and thinly populated territory receives more than 2,500 hours of sunshine on average per year, providing ideal conditions for wind and solar energy, and therefore green hydrogen production.
“If you look at where hydrogen is going to be produced in Europe in the next million years, it’s in two countries, Spain and Portugal,” said Thierry Lepercq, the founder and president of HyDeal Ambition, an industry platform bringing together 30 companies. “Hydrogen is the new oil.”
Lepercq is working with companies like Spanish gas pipeline corporation Enagas and global steel giant ArcelorMittal to design an end-to-end model for hydrogen production, distribution and supply at a competitive price. Criticism has centered on green hydrogen’s higher cost compared with highly-polluting “gray hydrogen” drawn from natural gas. Lepercq argues that solar energy produced in Spain is priced low enough to compete.
Globally, Lepercq said, “Electricity is 20% of energy consumption. What about the 80% that is not electrified? ... You need to replace those fossil fuels. Not in 50 years’ time. You need to replace them now.”

5 . Researcher Ruijia Hu said wildlife habitat in crowded places like south went Ohio is becoming increasingly fragmented (分散) as forests give way to new construction. Eventually, this could make trouble to an animal with specific habitat needs like Ohio’s pileated (红冠) woodpecker.
Pileated woodpeckers have the nickname carpenter birds for their never-ending natural woodworking. They peck out holes in trees for their nests every year, creating lots of valuable homes for animals like fox squirrels and owls. “They make new nests every year. They won’t reuse old ones,” Hu said. “Other animals depend on them.”
Pileated woodpeckers are private birds that are more often heard than seen. Studying them can be especially difficult. So Hu turned to citizen science for help. To identify where woodpeckers have been seen, she used eight years of sightings collected by birders and logged into the website eBird, a free online tool and app that anyone can use to record their observations and locations. She overlaid these sightings with remote sensing data and found that corridors along rivers and creeks with abundant mature trees and deadwood helped the birds adjust to their increasingly fragmented urban landscape.
“With fragmented forests, many habitats that were once suitable for wildlife are broken up,” Hu sa id. “Wildlife is unable to find habitat big enough to meet their survival needs. And even if there are suitable habitats, the distance between them can be too great. Wildlife corridors link up these habitat patches. Since wildlife can travel and migrate from one patch to another, the probability of finding food and shelter is higher.”
“There are so many species in urban areas that we don’t pay attention to, especially when they’re not considered vulnerable,” Hu said. “With development chipping away at more forest in this crowded county, the tipping point (临界点) could come quickly and unexpectedly. You can’t fix it overnight. It’s not just about planting more trees. The birds need mature forest, so it could take 30 to 50 years to replace their habitat. At least we can protect these riverside forest corridors and see that existing trees reach maturity.”

6 . While it throws out about 90 pounds of food per person every year, Japan doesn’t rank at the top of the world’s list of wasteful nations. Still, what’s thrown away represents a serious problem for an island nation with limited landfill space and a goal of greater sustainability. Reinvention can offer an alternative. A Japanese company is taking vegetable peels, cooking oil and other used foodstuffs and making entirely different products.
Concrete is the most widely used construction material in the world, and its key element, cement, is a major polluter of greenhouse emissions. So what if a more sustainable alterative were possible by making cement with food waste, which also would help reduce greenhouse emissions from landfills where that waste would otherwise be thrown away? That’s the idea behind Fabula, a Tokyo-based start-up.
Researchers at Fabula created a recipe to make food concrete by drying leftovers and pressing them into a mold (模具) at a high temperature. The company, founded by researchers at the University of Tokyo, began with items commonly thrown away like cabbage and orange peels but found that almost any food item can be used. It now takes mostly coffee grounds and tea leaves to make its cement. The product’s durability depends on the components.
Fabula is currently producing made-to-order household items, such as coasters and dishes, while awaiting its patent. The goal is to make furniture and larger structures once the technology is able to make the cement more durable. Food production companies that can’t avoid generating waste during their processes have reached out to work with the company. “We hope to become a matching service between companies that have food waste and companies who want to build things out of such materials,” said Takuma Oishi, Fabula’s chief commercial officer.
Since the cement is 100 percent eatable, it could create opportunities during disaster response when temporary structures need to be built quickly. The people inside might even turn to them for food. If the technology advances enough, Oishi suggested, someday we may be able “to eat the homes or furniture when necessary”.

7 . The rechargeable lithium-ion (锂离子) battery market is worth more than ＄50 billion. Lithium-ion batteries, whose demand continues to go up day by day, are used in a wide range of electronic devices. They are made of four main components, and cathode (阴极) is one of them. The cathode’s active material type is what determines the capacity of a battery.
A recent study, led by Wang Yan, a material scientist of Worcester Polytechnic Institute, finds that lithium-ion batteries made with recycled cathodes work better than those with new cathodes.
“The battery industry is expected to grow sharply in the next decade. This high demand has led companies to go to extremes, like increasing deep-sea mining, to gain access to the minerals used in lithium-ion batteries,” Wang said. “Mining minerals will have environmental impacts. Recycling spent lithium-ion batteries offers a way out.”
But until now, the prospect of using recycled materials in lithium-ion batteries has some manufacturers (制造商) worrying that it could impact performance. Thus, lithium-ion batteries are still not widely recycled. Aware of decreasing resources and environmental impact, Wang and other researchers set out to find a way to make recycling lithium-ion batteries economically practical. Through experiments, they could recover more than 90% of the key metals from spent batteries. These recovered metals became the basis of the new recycled battery’s cathode’s active material.
In tests between Wang’s team’s recycled batteries and brand-new batteries of the same composition, the recycled batteries outperform the new ones in their ability to maintain capacity. It took 11,600 charge cycles for recycled cathode batteries to lose 30 percent of their original capacity. That was about 50 percent better than the 7,600 observed cycles for new cathode batteries, the team reported. Those thousands of extra cycles could translate into years of better battery performance, even after repeated use and recharging.

8 . Michael Gonsalves, a chef of Golden Oak at Disney World, has a cuisine concept rooted in fresh, locally-sourced ingredients that originated from childhood harvesting produce from their family garden with his mom to eventually leading kitchens at Walt Disney World Resorts to employ a sustainable model.
“Truly the whole process starts with menu planning,” he said. Creating one dish leads into the creation of many more through the end-to-end use of products. As chefs, they are always searching for the best ingredients. It is then their focus to ensure they appreciate and respect all that go into each and every one of them. For example, they source chicken that is naturally grown and fed on a natural plant forward diet, no hormones (激素) or additives — that’s used in many ways throughout menus from a simple grilled chicken breast to bone soup. Nothing goes to waste.
When they do have waste, even if minimal, they shift it from landfills to transform it into compost (堆肥) that’s then used across the Walt Disney World property. They also support Second Harvest, a local community food bank where healthy produce, prepared, but not served, meals eatable for human consumption are donated. Disney also works with pig farmers when they can’t distribute foods past the point of safety for human consumption. Besides, wildlife reservations love to get the meat because tigers and wild cats can still eat that.
Their operations are “on a path to a sustainable zero waste kitchen of tomorrow” where chefs learn the full-life cycle of plants from seed to plate and gain a better understanding and appreciation for the product and their craft.
Golden Oak at Disney has millions of bees that produce up to 300 pounds of honey per year, plus those bees help with cross pollination (授粉) of their gardens on a daily basis. They advocate a culture that helps develop not only the quality of food, but an appreciation for nature.

9 . One man’s trash is another man’s treasure is absolutely the case in Turkey where garbage collectors started collecting books that have been thrown away and ended up opening a library.
It started when garbage man Durson Ipek found a bag of abandoned books when he was working and then it snowballed from there. Ipek and other garbage men started gathering the books they found on the streets that were ready for landfills (垃圾填埋地) and as their collection started to grow, so did word of mouth. Soon, local residents started donating books directly. The library was initially available only to the garbage employees and their families to use but as the collection grew, so did public interest and the library was opened to the public in 2017.
“On the one hand, there were those who were leaving these books on the streets. On the other hand, others were looking for these books,” Ankaya mayor Alper Tasdelen told CNN. “We started to discuss the idea of creating a library from these books. When everyone supported it, this project happened.”
All the books that are found are sorted and checked for condition. If they pass, they go on the shelves. Today, the library has over 6,000 books that range from fiction to nonfiction and there’s a very popular children’s section that even has a collection of comic books. An entire section is devoted to scientific research and there are also books available in English and French. The collection has grown so large that the library loans books to schools and educational programs.
“Village school teachers from all over Turkey are requesting books,” Tasdelen told CNN. The government has to hire a full-time employee to manage the library.
This library is incredibly popular. It is frequently filled with the children of the city’s workers and students from nearby schools. There is a waiting room set up for readers and chess boards for the people who visit the library. You can even enjoy a cup of tea in the waiting room.

10 . Every year, as the surface water temperature off the United States mid-Atlantic coast rises steadily from late spring through the summer, a pocket of uncharacteristically cool and crisp water gets trapped at the bottom of the ocean. Packed with nutrients this thick band of cold water, known as the mid-Atlantic cold pool, is a vital home for shellfish species. Extending at its seasonal peak from Nantucket, Massachusetts, to Cape Hatteras, North Carolina, the cold poll creates a diverse ecosystem ranging from algae(海藻)to fish — and some of the most valuable shellfish fisheries in the United States.
Now, however, two pressures have scientists worrying about whether the cold pool will last. The first is no surprise: climate change. Over the past five decades, climates change has destabilized the cold pool, causing it to warm and shrink. Compared with 1968, the cold pool is now 13℃ warmer and has lost more than one-third of its area.
The second concern is 1ess certain. In 2023, the US federal government approved plans to install(安装)98 wind turbines(涡轮机)off the New Jersey coast, covering an area of more than 300 square kilometers. Yet putting so many turbines to the seafloor could have unexpected consequences for the cold pool. That’s why Travis Miles, a researcher at New Jersey’s Rutgers University, and his colleagues are investigating. So far, Miles and his colleagues can’t definitively say what will happen to the cold pool, saying more research is needed to assess how climate change and offshore wind, together, could affect the cold pool. However, their initial analyses suggest the cold pool should be fine — at least in normal conditions.
New Jersey’s offshore wind plans are strongly opposed mainly by fossil fuel-industry funded efforts. Miles worries that an overabundance of caution or fear of potential impacts, including on the cold pool, might slow down the development of renewable energy. “...it’s quite clear that climate change is far more damaging than installing wind farms,” he says. “I don’t think any scientist would argue with that.”
