I can’t think of the way to cover the building with a cover cover, the body is hot ... What else is the way to become a treasure?

The following article comes from the WeChat public account: take the science home, the author everything

In the new waste into a treasure plan, scientists have followed the abandoned medical mask.

In recent years, medical disposable masks have become new consumables, and pollution problems caused by abandoned masks cannot be ignored. A 2021 survey found that 3.4 billion masks or masks around the world can be discarded every day, and 3 million masks are consumed every minute.

Although wearing a mask may protect our own safety, it may be difficult to handle with virus abandoned masks. Its impact on ecosystems and other creatures may be fatal.

The mask is thrown in the environment and enters the ecosystem, such as the ocean and river, or the habitat of animals. Seagulls, foxes, and even penguins have been banned by these masks, threatening life.

At the other level, the surgical mask is made of polymer and other polymers, which contains many micro fibers. Studies have found that only one mask falls in the ocean, and 170,000 microfiber is released every day. Many masks make tens of thousands of tons of micro -plastic waste enter the ocean and affect the marine ecosystem.

However, scientists have found a new idea to relieve environmental problems ... Use a mask to build a building!

It sounds unbelievable, but it is really true! Covering the building with a mask is not only low -carbon, but also stronger.

Researchers remove the ear hanging and metal wire on the mask, chopped the other fabric to chopped the growth degree from 5 ~ 30 mm, plus the oxygen oxyne solution. Finally, after a series of "mask" and ordinary cement mixed together, scientists will explore the "mask cement" effect of 7 days and 28 days later.

The results showed that a month later, the extension of the split stretch of "mask cement" mixed with a volume of 0.1%increased by 47%, but the pressure resistance was only 3%. In other words, this new type of cement is less likely to crack than ordinary cement.

In addition, the research team will also conduct further tests to prove that this "mask cement" has higher durability. If this cement is more durable than ordinary cement, the service life of the cement highway will be longer, reducing the carbon consumption generated by replacement and repair of cement, and it will also be more environmentally friendly.

The abandoned mask of our lives will also be recovered and played a greater role.

If you want to do everything you use, except for the abandoned masks in life, the calories of our body cannot be let go. When you are squeezing into the commute subway, the calories emitted by everyone will sweat you. In some places, these heats are used to burn water and heating.

The most famous is a building built on the Central Station of Stockholm, Sweden. Here, the daily flow of people is 250,000, and the heat pump will absorb the excess heat emitted during or activity, and use these energy to burn water.

The heated water will be sent to the nearby building for heating. In this way, the originally sullen station will become cooler, while other buildings will become warmer. Moreover, the energy consumption of the surrounding buildings is reduced by as much as 10%.

In 1996, Wolfgang Feist founded a scientific research institution -Passive House Institute (PHI). Passive houses are a more energy -saving house design. It aims to reduce energy consumption and use less energy to heat or cool the house. This building focuses on heat insulation and ventilation systems. It can not only heat up, but also prevent more heat from coming in, so that the rooms have comfortable temperatures throughout the year.

Today, passive houses have spread all over the world. The new train of the Gaobei Store in Hebei is the world's largest passive building complex. PHI will also contribute to energy conservation and environmental protection.

"Human heat cannot be the only heat source. But it is a good contribution," said architectural technical experts.

The pace of turning waste into treasure never stops, and there are always all kinds of wonderful thoughts that we are unexpected.

Can you imagine the lithium battery made by foam plastic? Foam plastic particles for packaging are difficult to degrade and are likely to pose a threat to the environment.

However, after heating the foam plastic in the inert gas to 500 ~ 900 ° C, it can be converted into carbon nanoparticles to make the electrodes required by lithium batteries. This new process is not only simple and practical, but also the new battery made can make the charging speed faster.

So, what about the convenience sticker of diapers?

Although it sounds like a storm. However, scientists point out that as long as they can successfully recover the ultra -water materials in diapers and women's sanitary products, they can be used to make other materials.

In one experiment, after complex recycling, high -absorbent materials were finally transformed into facilitating pressure -sensitive gums. This possible method can recycling the use of polymers and improve the consumption and waste caused by the original production route. Another unexpected waste into a treasure. | Pixabay

Maybe there are still people who are worried about hygiene. After a variety of high temperature, disinfection, and various chemical reactions, diapers are not the original diapers!

What else can I help in our lives? Do a good job of garbage classification!
