American scientists figured out how to turn plastic into fuel

Experts have called their technology hydrothermally liquefaction. It allows you to melt the propylene polymer and then dissolving them in supercritical water (in this state the substance is between liquid and gaseous phase). As a result of plastic turns into the substance from which it is possible to obtain hydrocarbon fuel.

The problem of environmental pollution by plastic every year is becoming increasingly important. Although some plastic debris is sent to recycling today we are talking only about a small fraction of such waste. At the same time, a significant part of plastic — according to some estimates, up to 12 million tons per year — goes to the ocean. Plastic debris finds, including small fish and jellyfish, and since these creatures are food for other marine life, microscopic particles of plastic “climb” up the food chain, threatening, in particular, and people who eat fish. Large sea creatures too suffer from such garbage — recently in Indonesia found beached carcass of a whale in the stomach of which was about six pounds of plastic.

Some evidence of plastic pollution are more than eloquent . For example, recently scientists have found that the so-called “garbage patch”, slowly moving between Japan and us state of California, includes more than 350 million tons of garbage. And in may last year, Australian scientists found in a relatively small and regarded as “unspoilt” island in the Pacific ocean 38 million items, which is a plastic garbage, weighing about 18 tons.

Experts suggest that at the current rate of ocean pollution by mid-century plastic it will be more than the fish.
