Environmentally Friendly Plastic Made From Salmon Sperm

Chinese scientists have succeeded in producing environmentally friendly plastics using the sperm of salmon. The only drawback of the material, which can be used like traditional plastics, is that it starts to melt when it comes into contact with water.

It is a well-known fact that a war has been waged against plastic materials in the world, but this war has not been won. However, recent developments plastic material revealed that a new era for its production may have begun. A group of scientists trying to produce plastic with alternative materials in China, using sperm from salmon succeeded in producing a material very similar to plastic.

It is produced by Chinese scientists working at universities named Dayong Yang and Tianjin. environmentally friendly plasticwas created by mixing two short DNA sequences found in salmon sperm with vegetable oil. This mixture formed hydrogel The experts, who freeze-dry the soft material called, have succeeded in producing a material that looks like plastic. Up to the present DNA model, Cup and puzzle piece production scientists think that the plastic alternative they have developed is promising.

Plastic produced from sperm has an important flaw: It melts when wet.

Like the production of traditional plastic, it is also difficult to recycle. The most important feature of environmentally friendly plastic produced in China, high solubility. Naturally produced material is easily destroyed in the natural environment. But this material has one significant flaw. So much so that contact with water brings the end of environmentally friendly plastic. The material that starts to melt becomes a hydrogel again. Experts say that this is not so important, for products that should not come into contact with water. they state that this plastic material can be used.

Even if the research was carried out on salmon sperm; this item belonging to different species It is thought that it can also be produced from sperm. However, the work done at this point is not enough. According to scientists around the world 50 billion tons weight of DNA, and DNA can technically be made into plastic.
