PARIS, December 7th – Would you drink from a mug made from salmon sperm?

You may have to overcome your initial reaction to reduce plastic pollution as Chinese researchers have developed a new biodegradable material that uses DNA from this fish’s sperm, which we usually prefer to enjoy in sushi.

What if the solution to reducing plastic pollution had (finally) been found by a Chinese research team?

On April 1, we might have doubted the news was correct, but scientists at Tianjin University extracted DNA from salmon sperm to create a gel-like substance that can be shaped into any shape.

More specifically, these extracted strands of DNA were combined with polymers from vegetable oil. A freeze drying process was then used to obtain this particular hydrogel.

The secrets of this surprising technique were found in the Journal of the American Chemical Society. In the publication, the scientists explain that this material – the main advantage of which is its biodegradable nature – was used to make a mug.

According to the researchers, a way has never been found to develop such an environmentally friendly plastic.

This material is said to cause 97 percent less CO2 emissions than making polystyrene-based plastic.

According to the non-profit organization Wings of the Ocean, around 300 million tons of plastic are produced worldwide every year. Between eight and 12 million tons end up in the oceans. In addition to these already alarming numbers, there are currently around 5,000 billion pieces of plastic floating on the ocean’s surface, according to scientific estimates.

With that in mind, you may not see your sushi place like this anymore … especially since it is likely served in plastic. – ETX Studio
