Technology to convert plastic into fuel at the temperature of a kitchen oven is developed
Although the problem of environmental pollution of plastic waste, which is discharged in large quantities every year, is regarded as a problem, human beings are still stuck in their dependence on plastic. For this reason, technological developments to reduce plastic waste are progressing as much as possible, and a new 'technology that can efficiently convert plastic waste into liquid fuel' has been announced.

Plastics Can Be Broken Down Into Fuel, And We Just Found a Great Method For It
According to UN data, only 9% of the plastic waste generated on Earth so far is recycled, 12% is incinerated, and remains untreated on Earth. The number of things is as high as 79%. Various studies have been conducted to solve such plastic processing problems, one of which is to convert polyolefin , which is the raw material of plastic, into fuel.
Meanwhile, a new paper published by a research team at the University of Delaware describes how to convert polyolefins, which are said to be 'especially difficult to recycle,' to liquid fuels such as diesel fuel, jet fuel, and gasoline-based hydrocarbons. I wrote it.
zeolite and a mixed metal oxide. Mixed metal oxides are used to break down large molecules, and zeolites play a role in facilitating the formation of branched molecules. Researchers say that these two catalysts can't work well on their own, but when used together they can turn plastic into energy. In addition, the fact that the two catalysts are easily available is also considered as a merit for practical use.
Until now, the technology of 'converting plastic into fuel' has been researched, but such technology has problems in terms of 'reducing costs' and 'reducing resources'.
In this regard, the new research requires 50% less energy resources than similar technology because the processing temperature required is about the same as that of an ordinary household oven, and carbon dioxide, which is a greenhouse gas, is added in the process of converting to energy. It will not be discharged into the air.
The research team decomposes carbon-carbon bonds in plastics using a chemical process called 'hydrogen decomposition' that uses a catalyst consisting of a mineral called
In addition, many of the plastics sold at the time of writing are blended with different types of materials, but with the above method, it seems that there is no need to separate multiple blended plastics.
Of course, such technologies do not fundamentally solve the plastic problem. To solve the problem of plastic waste, we need to move away from the very production of plastics using petroleum. This is acknowledged by researchers, and the team will continue to explore new ways to manufacture products.
