In 2018, a study of images taken at the bottom of the Marianne Trench, the world’s deepest ocean floor, revealed plastic waste at a depth of 3,300 feet. Entrepreneur Victor Vescovo, who is exploring the area, also reported the presence of plastic bags in the area. There is another eloquent fact. The United Nations predicts that by 2050 there will be more plastic than fish in the ocean. In this way, the diffusion of plastics is progressing with global warming. micro plastic has become one of the most pressing environmental problems. And while recycling can alleviate the problem, it is by no means a clear solution.development only innovative materials can work efficiently. Ironically, cures may be found where this kind of contamination is most severe. A group of scientists from Tel Aviv University technology project It aims to develop a new generation of seaweed-based bioplastics.
“Scientists at Tel Aviv University are developing a new generation of seaweed-based bioplastics.”
The steps they took to achieve this were Haloferax Mediterranei Bacteria that feed on the carbohydrates in seaweeds, which are metabolized as polyhydroxycarbonates, a type of natural polyester normally produced by bacteria by fermentation of sugars and lipids. Polyhydroxycarbonates are one of the most promising research areas. bio plastic Fully biodegradable, yet zero toxic waste. Until now, the production of this type of bioplastic required food crops at the expense of food production.This is a similar situation with biofuels, using edible plants to generate power Or plastic could affect malnourished people and drive up prices. Luckily, seaweed is a plentiful resource and doesn’t require anything. agricultural technology, This is the main reason why Israeli researchers chose Israel for these developments new bioplastic that deteriorate within a year.
Scientists are researching techniques to develop plastics with specific qualities for making plastic bags and various types of food packaging, and this technical research is still ongoing.
What other raw materials can be used to make bioplastics?
Israeli researchers aren’t the only ones dedicated to this research Development of new biodegradable plastics. Potato starch-based plastic bags are one of the most common choices, but cassava starch-based plastics, derived from roots used in African, Latin American, and Asian cuisines, are another option. However, both are used for nutritional purposes. therefore, sol bag maybe one of the most interesting technology solution. A water-soluble bag made mainly of limestone, developed by a Chilean company. Their bags dissolve in cold water and he dissolves in less than 5 minutes. This is significantly less time than the 400 years required for some petroleum-based plastics to fully decompose. In addition to this, carbon, a completely harmless compound, is the only by-product when the SoluBag dissolves.
