Plastic can be seen everywhere in life, whether from milk tea drink cups and straws, or breakfast in the morning to give you a plastic bag, whether it is the outer packaging of cosmetics or some plastic film, in a sense, it does make us feel convenient, but people's uncontrolled use, coupled with the plastic itself is difficult to degrade, resulting in white waste everywhere. Various countries are also doing a lot of efforts for this, the introduction of environmentally friendly paper straws, biodegradable plastic products, the implementation of carrying their own cloth bags to buy food and so on some of the measures, although you can still see the white trash, but really has been effectively improved.
White waste harms the food chain
May 5, 2021, in Yantai, Shandong Province, China, a resident to buy fish found fish belly abnormal, after shaving the fish belly found disposable plastic cups. When he used his hands to pull out a very large paper cup, netizens see the video is also very heartbreaking, so large, how it eats down, the bottom of the sea is also no fish doctor, you can imagine the tragedy of slowly waiting to die.
And the resident said that the fish seller boss told him that this situation is normal, and previously found in the fish belly inside the can. It can be imagined that this kind of thing has happened not once or twice, today the plastic runs into the belly of the fish, tomorrow is into our mouths body.
According to incomplete statistics, every year about 9 million tons of plastic waste is discharged into the ocean, and in the South Pacific sea, there is a plastic waste of more than 4 million tons of "islands", known as the "eighth continent", and although two decades have passed, there is still no environmental organizations can completely remove this "garbage island". Every year, humans create 300 million tons of plastic, which is piled up on large garbage islands, one in each ocean and five in total worldwide. There are about 5.25 trillion pieces of plastic floating in the ocean, and with so much plastic entering the food chain, marine life can easily swallow it, causing the loss of ocean life.
Recently there is a satirical short film in Thailand called: "Humans, why don't you eat plastic bags? In the video, the waiter cut the yellow and green red plastic bags into a strip, into the outside of the sushi is nori, to passers-by free taste, everyone said the first bite is delicious, but when eating out of plastic, with hands to pull out, expression painful, and very angry, said, we eat plastic bags will choke to death, I want to sue you! Such plastic made sushi humans feel will choke to death, what about marine life? Every day they do not know how many sea creatures eat this white garbage, gradually eyes can not see, gradually can not breathe, gradually stranded on the beach. And humans, as the top of the food chain, slowly pick up the sea species, slowly put on the table to ingest toxins, slowly affecting health.
The plastic that can't be given up
Keith Stevenson, a professor at Russia's Skolkovo Institute of Science and Technology, told the press that the many advantages of plastic make it impossible to give up using the material. He claims, "I don't think mankind will ever give up plastic. Plastic has so many advantages that giving it up would be like going back to the Stone Age."
The professor explained that other options are currently more expensive than plastic. In addition to replacing plastic with wood or biomaterials, developers will pay more attention to the manufacture of recyclable plastics. Stevenson supports the elimination of unnecessary single-use packaging.
Finger a little, sit back and wait for the takeaway to be delivered to your door. Enjoying food without leaving home or going downstairs is becoming a dining habit for more and more young people.
The take-out service provides the popular fast and convenient and delicious food at the same time, the environmental problems brought about by the countless disposable lunch boxes every day have aroused social concern, and also make the use of more easily biodegradable materials for lunch boxes, focusing on environmental protection and health and safety of the growing call. Because of this, major companies with big-picture thinking and long-term vision have also continued to make efforts in the field of environmental protection to open a new track of development in the take-out service of the catering industry.
In the management of white pollution, promote a green lifestyle today, to degrade faster starch-based lunch boxes and other environmentally friendly tableware on behalf of the market is gradually entering. However, due to poor popularity and low market recognition, its market share is far inferior to that of pure plastic disposable lunch boxes. Enterprises should innovate degradation technology and process to launch greener and more environmentally friendly plastic products; the government should strengthen public guidance and industrial support; the public should raise environmental awareness and take the initiative to purchase more environmentally friendly products. We hope that through the efforts of all parties, biodegradable products will become popular.
A take-out box, from full of meals to be sent to the hands of diners, to the final discarded, usually only a couple of hours. A large amount of raw materials and energy consumption, only in exchange for a brief use, after that, but a long natural degradation, or time-consuming and laborious artificial degradation, the cost is not small. I hope that in the market of disposable lunch boxes, there will be more products with better biodegradability, but more importantly, I hope that people will practice a green lifestyle, reduce the amount from the source and start from using less or no disposable products.
Conventional plastics do not degrade for hundreds of years under normal conditions and can cause a lot of damage to the environment. If it is in coastal areas, it will also have a great impact on the surrounding marine environment. As the best alternative to plastic, PBAT material can be decomposed in a short time, and the decomposition products are also water and carbon dioxide, which is more friendly to the environment.
Since the introduction of plastics, scientists have been working on the anti-aging, or stabilization, of such materials to produce highly stable polymer materials, and scientists in various countries are competing to develop environmentally degradable plastics using the aging and degradation behavior of polymers. Biodegradable plastic project is the development path that plastic product companies can't get around if they want to develop sustainably.
