According to Singapore’s “Lianhe Zaobao†reported on the 17th, American scientists have developed a new technology that can convert plastic shopping bags into diesel, natural gas and other petroleum products.
According to reports, the petroleum products produced by this technology for converting plastic bags far exceed the energy consumed in this conversion process; these fuel products include diesel, natural gas, solvents, gasoline, waxes, or engine oils and lubricants.
"We can only get 50% to 55% of the fuel from the crude oil distillation process, and the plastic bag was originally a type of petroleum product, so we can use it as a raw material," said Sharma, an American University of Illinois scientist who led the study. Nearly 80% of the fuel is distilled.†The results of the Sharma Group's study are published in the latest issue of the Journal of Fuel Processing Technology.
It is understood that as many as tens of billions of plastic shopping bags are thrown out every year in the world, only one-eighth of them are recycled, and the rest are either sent to landfills or thrown into the sea or in the wild.
Plastic bags not only cause pollution on land, they are also an important part of marine pollution sources, and undecomposed plastic bags also pose a certain threat to wildlife. For example, the turtles will see the entire plastic bag as jellyfish and swallow it. Other creatures may be wrapped in plastic bags and cannot escape. Researchers say plastic bags even appear in sparsely populated areas such as the Arctic and Antarctic.
The report said that scientists had previously studied how to convert plastic bags into crude oil, but this was the first study to successfully convert plastic bags into diesel. Sharma’s research team even further made crude oil into various petroleum products.
Sharma said that the researchers mixed 30% plastic diesel into common diesel and tested it. The results showed that the blending with biodiesel worked well and there were no compatibility problems.
Bathroom Tap buying guide: A simple rule for most basins is this: look for taps that extend as far as the plug hole. Lower spouts are good for smaller, cloakroom bathrooms where space is tight. Higher spouts make it easier to wash and shave. Longer spouts are suitable for larger bathrooms and basins where space isn't an issue. Wall mounted tap: Wall mounted taps are an effortlessly elegant option for the modern bathroom and look incredibly striking. They protrude over the bath or basin and contribute to a highly integrated feel. Wall mounted taps can be more challenging to install than standard taps because the pipes and plumbing are hidden within the wall itself. Once installed however, wall mounted taps add a luxury feel and breathe new life into an otherwise tired bathroom décor.
