And of those 6.3 billion metric tons of plastic waste, only nine percent has been recycled. National Geographic says that of the whopping 8.3 billion metric tons of plastic the world has produced, 6.3 billion metric tons have become plastic waste. But when you actually take a look at the numbers, it’s downright shocking. “We are now conducting basic research to find the best bacteria and algae that would be most suitable for producing polymers for bioplastics with different properties,” Golberg concluded.It’s no secret that the world produces-and wastes-mass amounts of plastic. “We have proved it is possible to produce bioplastic completely based on marine resources in a process that is friendly both to the environment and to its residents.” “Plastic from fossil sources is one of the most polluting factors in the oceans,” he said. “There are already factories that produce this type of bioplastic in commercial quantities, but they use plants that require agricultural land and fresh water,” he explained.”The process we propose will enable countries with a shortage of fresh water, such as Israel, China and India, to switch from petroleum-derived plastics to biodegradable plastics.”Īccording to Golberg, the study could revolutionize the world’s efforts to clean the oceans without affecting arable land and without using fresh water. “These algae were eaten by single-celled microorganisms, which also grow in very salty water and produce a polymer that can be used to make bioplastic.” “Our raw material was multicellular seaweed, cultivated in the sea,” Golberg said. To do so, the researchers harnessed microorganisms that feed on seaweed to produce a bioplastic polymer called polyhydroxyalkanoate (PHA). “Our new process produces ‘plastic’ from marine microorganisms that completely recycle into organic waste.” But bioplastics also have an environmental price: to grow the plants or the bacteria to make the plastic requires fertile soil and fresh water, which many countries, including Israel, don’t have,” he added. “A partial solution to the plastic epidemic is bioplastics, which don’t use petroleum and degrade quickly. So bottles, packaging and bags create plastic ‘continents’ in the oceans, endanger animals and pollute the environment,” said Golberg, a senior lecturer at TAU’s Porter School of the Environment and Earth Sciences. “Plastics take hundreds of years to decay. Michael Gozin from Tel Aviv University, was recently published in the journal Bioresource Technology.
The study that led to it, carried out by Alexander Golberg and Prof. The result is a biodegradable polymer that produces zero toxic waste and recycles into organic waste. These can be bred in salty seawater without impinging on scarce freshwater resources. This is the problem researchers from Tel Aviv University wished to resolve by developing bioplastic polymers derived from microorganisms that feed on seaweed.
Other countries suffering from the same problem are China and India, whose size and resulting plastic consumption is very bad news for the planet. One such country is Israel, which does not have a surplus of fresh water. But these bioplastics can’t be created everywhere since the plants they use require fresh water, a scarce resource in many countries. That’s why bioplastics – plastics made from renewable sources like plants or old waste – were invented. Everyone knows plastic is bad for the environment.
