Extraction of bioplastic production from food waste

When you want to drink water you will see plastic cups; when you eat you will see plastic bowls; when you wear clothes you will see plastic buckles; it can be said that plastics are everywhere in our human activities. The problem of environmental pollution caused by plastics is more serious. According to the investigation of researchers, plastic pollution can even penetrate the polar ice far in the Arctic and Arctic regions, and even researchers have been in the Mariana Trench at a depth of 11,000 meters. A plastic bag was found inside. Moreover, in our daily life, plastic particles will enter our bodies, and every week we will eat the same amount of plastic particles as the weight of the credit card, which will have a weight of about five grams.

     In order to alleviate the environmental crisis and reduce the pollution of plastics to the environment, researchers are working hard to develop degradable stuff that can replace plastics, thereby reducing environmental pollution problems and not affecting people’s normal life needs. It is difficult for us to imagine a world without plastic products. At the same time, we are also threatened by the problems posed by plastic pollution. The team led by Professor Juan Carlos Colmenares at the Institute of Physical Chemistry of the Polish Academy of Sciences is studying a completely biodegradable material to replace plastic, and it has been successfully extracted from food production waste Hydroxymethylfurfural (HMF).

Comments responded: We hope to find a material that can degrade in just a few months or years to replace PET. Today ‘s petroleum-made plastics contain phthalic and other plasticizer an organic or even inorganic compound of sugar, which themselves has no bacteria or fungus to break them down. The materials produced based on DFF contain furanose, and substances from nature more susceptible to the influence of nature. The team led by the professor has tested these polymers and they break down into sugar-like monomers.

     Sugar is delicious food for many microorganisms. Even if a whole bottle of plastic made of this material is thrown into the forest, it will decompose much faster. And the traditional polymer the earliest will be a few years later. But not because the material of this product is new, but because of the method of producing this product. In the past, the bio-plastic production required at least a high temperature of 100-150 degrees Celsius and very complicated technology, but the bio-plastic produced ecologically better than plastics made from crude oil, but the price is relatively high.

    Now, the nanorods they produce from manganese dioxide which act as a catalyst can accelerate the partial oxidation in the production process. This plastic can be produced at a lower temperature and atmospheric pressure, Colmenares The professor explained: This is because the structure of the nanorods is very long and still very thin, this structure can better absorb light and heat. Because the uniqueness of manganese dioxide is that the thermal photocatalytic performance is relatively strong, manganese dioxide makes it more active. And as long as the LED lamp in the ultraviolet range and the air containing oxygen at room temperature can convert HMF to DFF. In the end, basically, all HMF is converted into 100% DFF. This is a waste-free process and does not require oxygen and additives similar to hydrogen peroxide. The professor is very happy: the nanocatalyst can also be used multiple times because DFF does not destroy it.

Some people worry that the plastic of this material may decompose too quickly, which will be very inconvenient when used, but Professor Carl Menas said: This material still needs a long time to degrade, but compared to traditional materials the time is relatively short, although people may drink a little “harmless” plastic because of its decomposition, it will also be decomposed by bacteria and enzymes in our stomach, so it is absolutely safe for our body.

Marine pollution and straw bio plastics

Water-degradable plastic synthesized by starch and cellulose

Marine pollution has become a hot topic in recent decades, and it is gradually threatening the safety of marine life and humans.

How is marine pollution caused? With the development of the world’s industry, marine pollution has also become more and more serious, causing great changes in the local marine environment and the trend of continued expansion. In order to save costs and time, the factory dumped a lot of waste into the sea, which caused the accumulation of marine debris. The most important thing is the accumulation of plastic garbage because traditional plastic scattered in nature is difficult to degrade by itself. Therefore, the discovery of marine biodegradable plastics has become an important task for contemporary scientists.

Previously, two Japanese companies jointly developed marine-degradable plastic, but the low output and poor quality of this plastic made it difficult to meet the normal demand of the world market. These disadvantages led to the limited use of this product. Therefore, there is an urgent need to develop a low-cost, high-yield, good-quality product for us to use, to clear the extent of marine pollution, solve the problem of garbage accumulation, improve our marine environment, protect marine life, and avoid marine life caused by accidental eating. Die.

Among them, two professors at Osaka University led a team to study this issue. As we all know, starch and cellulose are almost everywhere in nature and widely distributed. Starch is the main component of carbohydrates, and cellulose is the main component of plant cell walls. This means that in the research, the water-resistance of starch needs to be improved first so that the synthetic plastic can be perfect. The raw materials are not only cheap, but the manufacturing process is simple, the cost is low, and the time is short. If this R & D product can be put into the market, it will definitely alleviate the problem of marine pollution, reduce marine debris, and give us clean sea effectively removed threats to marine life and human health.

For this technical achievement, all major scientists and laboratories should make effective use of those low-cost, easily-available and widely-existing substances as far as possible, so that the emission of harmful gases can be reduced, to protect the global environment and reduce the destruction of nature.

In the face of the deteriorating global environment, the protection of nature has become a general trend. In accordance with the principle of sustainability, the available waste should be recycled to minimize the harm to nature. After all, the earth is our only home now. It should be cherished.

Using starch and cellulose to synthesize degradable plastics, I believe this technology can effectively solve the environmental pollution problem. The current research direction is not just to find products that little harm to the environment, but more importantly, to discuss raw materials, pay attention to the use of waste, and the use of widely distributed substances, follow the requirements of sustainable development.

How to Manufacture the Biodegradable Plastic Cards

How to manufacture the Biodegradable plastic cards with BioSheet™ ? Is there any technical difference between Bio-based plastic cards making and normal PVC cards making? Do you need additional equipment by using BioSheet™?

PVC cards are normally produced by laminating solid plastic sheets together and then die cut with certain sizes. There are three processes in simple.

Unless for blank PVC cards making, the first stage is offset printing with typeset artwork on a single PVC sheet with thickness of about 150 μm (micrometer) Normally two PVC sheets for front and back artwork respectively.

The second step is to laminate in between 3 to 7 layers of PVC sheets using a combination of heat and pressure to form a final sheet, with printed PVC sheets on top and bottom side. The thickness of each PVC sheet is about 80 μm to 250 μm, the thickness of final sheet is about 760 μm to meet the CR80 card standard. There will be an extra step of Inlay making for RFID card which the final thickness is around 840 μm.

Die cutting is the last step to get each laminated PVC sheet into several expected shapes by different molds. For example to use the mold of CR80 size, you will get the PVC cards with standard credit card size of 86 x 54 x 0.76mm (2.13″ x 3.38″ x 30mil).

How PVC cards made and how those production equipment designed were based on the physical characteristics of PVC. BioSheet™ were designed also according to those characteristics with greener solution.

Little plastic straws become big environmental crises

In the UK, 7.7 billion plastic bottles are used every year. Every year, about 80 million tons of plastic is poured into the sea. The ocean looks endless. It seems that no matter what humans do, it will not affect it, but we are wrong. The humble plastic tube takes hundreds of years to degrade.

At present, the severity of ocean pollution has caused widespread concern worldwide. Since April 2020, the United Kingdom has strictly prohibited the sale of plastic straws, plastic mixers, and plastic swabs. These measures will be fully implemented in England, and it is hoped that these measures can limit marine pollution, and the United Kingdom will also take new corresponding measures to improve the control measures. The British measures are recognized by environmental protection organizations and require the government to take more effective measures and actions.

To what extent will small objects such as plastic straws and plastic mixers that are visible every day be affected? The government’s press release released new provisions on “prohibition of the supply of plastic straws” and hopes to achieve the effect of restricting the number of straws.

Out of consideration for the necessity of drinking straws for disabled people, and for their mood, they can buy drinking straws without showing a disability certificate, and also to prevent them from dehydration. In addition to online stores and pharmacies that can be sold, other stores, including the market, cannot sell plastic straws. According to the content of the announcement, it can be provided in places such as pubs and restaurants at the request of people, but it is not allowed to sell actively.

So what else is in the file? Plastic mixers are banned. For plastic swabs, although they can be sold to the public, they are mainly sold to medical uses, scientific research, or criminal forensics. Defra said that about 1.8 billion plastic cotton swabs are used and discarded in England every year. During the filming of “Blue Planet 2”, David Attenborough, our familiar “Father of World Nature Documentaries”, witnessed the ocean with his own eyes while dedicating a frame of beautiful blue pictures to the fall Plastic pollution. After this landmark documentary, the government made a decision to ban plastic and took action. At that time.

Environment Minister Mr. Gove had been worried about the marine life that was hurt by plastic, and proposed a series of Discussing the measures of sex items, he said: For such items that are used for a few minutes but take hundreds of years to decompose, they will eventually enter the ocean and damage marine living resources. Therefore, we must not only for ourselves but for future generations. While England is taking measures, the Welsh government is doing similar preparations, and the European Union has also listed a list of some plastic materials and restricted them that officially adopted a plan.

At the same time, informal organizations are also doing with related efforts, environmental organizations agree with the government ‘s actions and measures, but are still concerned about plans for further implementation; WWF optimistic about the measures of various countries, calls for full control of disposable plastics by 2025; Marine Protection Association It is found that 17 plastic cotton swabs can be found per 100 meters on the beach in England. Gove believes that the recycling rate should be increased to reduce plastic consumption. When seeing the use of degradable plastics in takeaway restaurants, the Campaign to Protect the Country of England believed that the use of alternative products by Mr. Gove would also cause harm to the environment and that the production of disposable items should be completely banned.

Turn food waste into Bio-plastics

Environmental issues have always been the subject of discussion, and the pollution problem of the earth is becoming more and more serious. Especially for white pollution, as the number of people increases, the usage doubles. The seemingly convenient way has gradually accumulated into the biggest pollution problem. To solve the plastic problem worldwide, we must first clean up all plastics in the ocean, rivers, and rubbish dumps. Then we need to find an alternative that can reduce the burden on the environment. It can replace the component of polyethylene terephthalate compound with a material that can easily decompose plastic.

Australian student Arora did this. She set herself the goal of inventing bio-plastics and tried a variety of different materials, from the initial manufacture of water-soluble starch to the failed banana peel. After failing again, she turned to prawns, and she noticed the similarities between shells and plastics in the course of a journey to a local fish shop.

“These initial projects have won me more competitions. After expanding the influence, I can use better equipment in the university laboratory.” This is her influence after her early success.

After studying the ingredients of shellfish, such as lobsters and crabs, Aurora discovers that chitin exists in crustaceans, and this carbohydrate is also present in many types of insects. Aurora combines the insoluble protein present in silkworms with chitin to produce a plastic analog through chemical processing. This material can be dissolved in the earth within 33 days at open-air temperature, and its decomposition rate surpasses the million of ordinary plastics. Times.

In 2018, Arora’s invention made her win the BHP Billiton Market Innovation Award in competition with students from 81 countries at the Intel International Science and Engineering Expo. She won fourth place in the world and received a comprehensive scholarship from a famous American university. She also pointed out in a speech at TED: Australia is the largest consumer of seafood, and in cooperation with the fish market, a large amount of chitin was extracted from the shells of shrimp and crabs; and in the United States, shrimp is the largest local consumer. Every year, about 400 million pounds of shrimp are caught and supplemented by products imported from farms in various states. In the end, more than one billion pounds of shrimp will be eaten. This consumption is very surprising. From the data, we can see the development potential of new plastics, and new plastics have already attracted the attention of some companies. If the project can be vigorously promoted, the world will become more and more beautiful. The environment of the earth will be further improved.

Arora said that their main goal now is to recycle consumer waste and that several of her patents have not yet been decided, and she is now pursuing a medical degree. I hope to see her more creative inventions.

Protecting the Marine environment

The ocean accounts for about 70% of the total area of the earth. Not only does it play an irreplaceable role in the life of the earth, but it is also very important for everything in the world. Although the ocean is profoundly affecting our human life, there are still countless threats that are deeply hurting the ocean.

About 18 billion pounds of waste plastic is dumped into the ocean every year, whether intentionally or unintentionally. If we humans do not pay attention to restricting our own behavior, at this rate of white pollution, we will end up our own consequences by 2050.

Why do you say this? Because plastic is difficult to degrade, it can live on the earth for 1000 years, and the plastic contains toxins. If it is discarded in the ocean, it will not only cause the extinction of marine life, but also endanger our human health, and may also disrupt the balance of the global ecosystem.

Filling our oceans with plastics is undesirable and unsafe. First of all, plastics hinder the propagation of light in seawater. A large number of microplastics float on the surface of the ocean and are suspended in various layers of seawater, which hinders the transmission of light in seawater, affect the use of light by various organisms in the water, and interferes with their normal life activities. Secondly, if discarded plastics are thrown into the ocean, it is very likely that marine life will mistakenly think that these things are edible, that is, by mistake, but plastics cannot be digested by marine life. Slowly, these creatures are not starved to death and are poisoned by poison contained in plastic. Then, those fish that swallowed toxins in the plastic body are likely to be served on our table. Everything in the world is connected, no matter what you do, it is possible to return to you in the end.

The toxins contained in plastics are directly related to common problems of human health, such as cancer, immune system problems, and birth defects.

How should we solve the problem of ocean pollution? In 2019, the former Governor of California promulgated the Parliamentary Act of 1884, which prohibits restaurants from actively offering plastic straws to guests who eat at the restaurant unless requested by the guests. This is the first step taken to combat marine pollution, but it is just a small measure to protect marine life and clear the marine environment. There is still a long way to go. As we all know, the problem of plastic bags and disposable packaging should be solved urgently.

The government should encourage scientists to give them the opportunity to discover and promote degradable plastic bags; and, formulate laws and regulations to regulate the plastic production process and recycling process. In addition, enterprises have to take responsibility to effectively monitor the production of plastic products. Although they have no great effect, they can at least relieve the pressure on the marine environment. If possible, they can gradually change the production system to reduce plastic problems. At the same time, consumers should increase awareness of environmental protection, pay attention to recycling issues, pay attention to garbage classification, reduce the purchase and use of disposable products, and if possible, they can be reused multiple times.

Everyone is responsible for protecting the environment. When something goes wrong, we should not shirk our responsibilities to each other, but to unite and unite with the outside world. Each of us should have a sense of protecting the environment and reducing plastic pollution, not only for the protection of marine life but also for the protection of our human health.

Severe pollution caused by epidemic prevention single use plastics

Single use plastics in COVID-19

In the course of the epidemic, in order to prevent the spread of Single use plastics in COVID-19 pandemic, it means that the disposables are widely used and huge in quantity, especially for medical treatment, it also an army of medical waste, such as a double bag of clinical waste. Although it seems insignificant, it is also a large amount accumulated. This has a serious impact on environmental protection.

In a survey of consumers, it was found that the public also use multiple types of disposable plastic products for personal health reasons, and also generate a large amount of single-use plastic waste. In the course of the outbreak, quite a few restaurants, food stores, and coffee shops, including home delivery services, also used disposable plastic supplies, and were not allowed to bring their own reusable items. For medical workers, reusable items are not allowed in hospitals and other places. As the spread of new corona virus expands, the number of disposable items such as disposable wipes, disposable masks and gloves has been pushed to the peak for personal hygiene. Although this is a necessary measure, the pollution it produces is also huge. And medical pollution is even more worrying.

Plastic producers in Europe and American countries took advantage of the epidemic situation to resist the implementation of plastic bans on the grounds of health, which led to the withdrawal of plastic bans in many regions. But sustainability and recycling work proceeds, and environmentalists around the world are still spare no effort to it. So how should the above problems be solved? Someone is already working on it, such as the Boomerang Alliance ‘s Plastic Free Place project, which launched a cafe and restaurant guide during COVID-19. It shows how to avoid single-use plastics. Although the ban on plastic bags will be relaxed in a short period of time, it will still have a lasting impact on people.

Regardless of whether the epidemic will end in November, we should also be vigilant about environmental protection during the epidemic. Don’t let single-use plastics become a habit. You can use your time at home to sort out items that can be used for a long time. Reject disposable tableware and other items for personal reuse items, so that they can have a second life, although many secondary markets were forced to close their business during the epidemic, but hope that all items can have the opportunity to be reused. You can use personal private goods multiple times to reduce the effects of one-time pollution. Even if you have to, you must use degradable materials as much as possible and don’t make our planet given rise to too many of our mistakes. Therefore, we should call on the government and the masses to avoid one-time consumption and not allow the epidemic to become an excuse to increase plastic pollution. After the epidemic, we will pay more attention to environmental issues and be more clear about the pollution treatment in the epidemic.

New hidden dangers of plastic pollution: masks from COVID-19

Plastic is a scientific product of the twentieth century. It was created with the original intention of facilitating people. However, it is now causing great harm to the world. Therefore, countries around the world have begun to deal with this hazard and reduce pollution as much as possible. Environmentalists have greatly appreciated this, but another threat has slowly grown. With the development and spread of new corona virus, personal protective equipment for combating viruses is becoming another major problem in the world.

During the fight against COVID-19, masks are a necessity for people’s lives, so they are mass produced, and at the same time the handling of used masks has also become a problem. It will pose a huge threat to our environment even if a mask is handled and recycled properly by a research report. Because the environment we live in is different, the measures for recycling are not as extensive as those promoted, resulting in a large number of masks scattered in nature every month. The composition of the mask contains plastic, which means that many plastics are not processed in time, which means that it adds a burden to the contemporary environment.

Those masks were not handled properly were discovered by us in the ocean. These wastes are considered by marine life to be predators, threatening the safety of marine life. Plastic waste is deeply hurting the world. Not only affects us humans, but also causes harm to live things, but also threatens our nature.

It is necessary to strengthen the management of plastic waste, not only for the government, but also for our own human beings. Each of us should pay attention to our actions, recognize the hazards of plastic waste, protect the environment, and protect nature.

Another substitute for plastics bags

The white pollution has brought great harm to the world. And an army of plastic rubbish is dumped into the sea every year. Therefore to find a substitute for plastics bags has become the most important task for modern scientists.

Recently a British female student named Lucy Hughes product biotechnology from fish scales and fish skin. She is a very creative and hard-working girl. Once, Hughes has a chance to appeal the product at the bloody waste from a fish processing plant many people feel nauseated when they see internal organs, and Hughes is no exception, but she is still inspired. She has lived by the sea since she was a child, so when she was brought up she kept some local things as much as possible. She tried more than one hundred combinations, made constant corrections, and learned lessons and lessons. In the end, Hughes succeeded without losing his efforts. The successful test product is a translucent, strong, tough plastic-like feeling. The final product has a greater advantage than the current plastic bags. It meets the requirements of environmental protection and can degrade itself within four to six weeks. Its raw materials are few and depend on waste utilization. Some waste materials are very valuable. If we can recycle waste materials how happy it is.

This product won the James Dyson Award. And received a bonus. Hughes said that sustainability was not an idea under the threat of the current ecological environment. Environmental design is something she has always loved and will stick to, and is inseparable from her life. Sir James Dyson said that Hughes ‘invention not only solved the problem of disposable plastic pollution but also perfectly solved the problem of fish waste. Since the research report shows that 27% of the fish caught are not used.

The leftover waste from the use of an Atlantic cod can produce 1,400 bags for people to use. Hughes’s concept is to continue to develop this product and promote it to the world to produce more sustainable choices.
