Recycling disposable masks into fuel

08.08.2020

The quarantine measures associated with the coronavirus pandemic have shown the world how much a person affects the environment. However, along with positive changes, noise reduction, water and air purification, our planet has also faced negative consequences. Namely, with a huge amount of waste of personal protective equipment (PPE). Now, scientists at the University of Petroleum and Energy Research in India say plastic from PPE can be converted into a renewable fuel.
Scientists propose to recycle disposable masks into fuel

The experts proposed a strategy that could help mitigate the problem of discarded PPE. Currently, the number of disposable masks has increased dramatically, and scientists say that this is becoming a significant threat to the environment.

Billions of items of polypropylene PPE can be converted into biofuels. Lead author Dr. Sapna Jain explains that converting this type of waste into pyrolysis oil (a type of synthetic fuel) "will not only prevent serious environmental consequences, but also create a new source of energy."

The main problem with PPE is their material - polypropylene. Its disposal is extremely difficult and requires chemical and physical methods. Once the masks end up in a landfill or in the ocean, they stay there for decades, as their natural degradation takes a very long time.

So scientists came to the conclusion that the best way to recycle is to recycle the material into something else. The researchers say that with the help of pyrolysis (a method of thermal decomposition of organic and inorganic compounds), polypropylene can be processed into fuel. This process is one of the most promising and sustainable waste recycling methods compared to incineration and landfilling.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Childhood addiction to social media leads to overeating 11.03.2021

Children of nine or ten years old, who spend a lot of time on social networks, begin to eat too much.

Scientists analyzed the behavior of more than 11 thousand children, who were observed in 2016-2019. The researchers analyzed the time that children spend on social networks and in front of TVs, how much they correspond in instant messengers, etc. Parents were also asked about the behavior of their children.

According to research, every hour spent on social media increases the likelihood that a child will overeat in the next year by 62%. We are talking about short periods when a person experiences an attack of overeating. Watching videos increases this risk by 39%.

This eating disorder can lead to diabetes and cardiovascular disease. Scientists note that the reasons for this may be different: food advertising on the Internet, lack of control while on social networks or when watching a movie, etc.
