Hot cups are harmful to health which should pay attention to

Speaking of harm, we must clear the dose to determine the concept of toxicity, that is, whether the lid will be hazardous to health, or depends on the amount of styrene monomer.

The amount of styrene monomer migration depends mainly on the temperature of the contact and the level of grease in the food and the contact time. Coffee, tea and other hot drinks, from the hot cup to the consumer to spend the time is generally very short, and other hot drinks cups and hot drinks contact is occasionally.

In the study of styrene migration of polystyrene packages used in packaging hot drinks, it was found that the amount of styrene monomer migration did not exceed 0.025% of its content. Based on the results of this study, it is assumed that the styrene monomer content in the polystyrene resin is 0.5% of the upper limit allowed in China and the amount of styrene monomer in a hot beaker (about 2-3 g in weight) is about Is 3.75 μg. The tentative daily maximum allowable intake of styrene developed by JECFA is 0.04 mg / kgg. For people weighing 60 kg, the maximum daily intake is 2400 micrograms. To achieve this amount of damage, the equivalent of about 640 per day (correction, the original is written in 107, in the calculation of the mistakes) of this hot cup, under normal circumstances it is difficult to achieve.

In addition, the amount of styrene monomer that may be dissolved by a lid may be lower than the amount of styrene in a bottle of beer. And worry about hot drinks cup lid, not as worried about the hazards of alcohol and tobacco, tobacco and tobacco carcinogenic harm is the evidence is very full.

At present, the US FDA believes that the release of styrene from polystyrene packaging materials can not meet the JECFA assessment of this harmful dose, so allow it to dress food. The Canadian Department of Health after the assessment that people contact with the amount of styrene monomer can not cause harm to people. According to the current world of use and research evidence, polystyrene food packaging materials as long as the use of properly, there will be no food safety problems. But it will cause the pollution, so we should pay more attention to the Styrofoam recycling to reuse the waste foam packaging.

Hot take-away market has caused great "white garbage" pollution

In the afternoon of a working day, CCTV financial reporter walked into a large office in Guangzhou City, lunch just over, floor trash can be "white garbage" completely occupied. Clean workers told CCTV financial journalists, where the plastic waste is a lunch box. Sanitation workers said that the total amount of garbage, plastic bags are more, most of the foam boxes, which cause large workload.

In order to save costs, businesses take delivery time, most of the use of disposable plastic lunch boxes. And even the environmentally friendly materials, lunch boxes, but also often as a one-time items, run out of disposable, and then very low utilization rate.

Take-out meal service introduction, the bubble occupy most of the time, about 60%. Reporters interviewed the people of Guangzhou, also said that lunch boxes are used up when the garbage out. Like this point of a takeaway, how much environmental costs to pay it? US group take-away, hungry what, Baidu take away three takeaway platform data show that the total daily orders have more than 20 million single according to a single take-away only a plastic bag and a plastic lunch box, each plastic bag and plastic lunch boxes are 0.06 square meters, a rough estimate, each meal platform every day the size of the waste plastic, can reach 2.4 million Square meters, about the equivalent of 336 football fields.

Data show that only 14% of the country's plastic packaging has been recovered. And now, takeaway businessmen to provide lunch boxes, in addition to environmentally friendly paper tableware, polypropylene (PP) tableware, but also includes four years ago lifted the one-time foam tableware.

For a large number of unmanned foam tableware, experts said that if companies want to do EPS recycling, environmentally friendly pollution handling system is too expensive, so this kind of take-away garbage, generally only incineration. If you want to encourage the recycling of waste plastics and other renewable resources, you need to establish a corresponding subsidy mechanism.

Polystyrene has a certain applications in our daily life

A number of cars were crushed against the concrete ceiling when an underground car park was deluged with water on Sunday morning. Some vehicles’ roofs crumpled after polystyrene insulation under the car park floor appeared to swell, forcing them upwards.

The floodwater was caused by a burst pipe and was several feet high in the newly built car park, which is below a residential block of flats in Crayford, south-east London.

Residents were reportedly warned that if any of the cars were removed too hastily it could result in a gas explosion. One owner was told her car was written off as a result of the damage.

The flooding caused considerable travel disruption after filling the road near Townhall Square, and it left a number of homes without water. Sadia, 42, left her black Ford Fusion in one of the affected parking spaces on Saturday, and returned to find it ruined.Between 12 and 16 cars are said to have been damaged.The mother of two said: “My car is crushed, the roof is gone, the ground has come up - it is a bad architectural design.

"I had another of my neighbors with me and her car was okay, but we were told we cannot move it because there is a possibility with the pressure of the car there could be a blast because of the gas inside of the polystyrene, or something. It can blow up the whole building.”

The problem is who to contact. Someone has said the car insurance might not cover it because it didn’t happen from the driver him or herself. We are in really, really bad shape.

Because of the bad effect of plastic waste, we should think ways to solve these problems, and plastic recycling is a good EPS disposal, which not only can protect the environment, but also can save the waste resources.

Plastic pollution affects the Sydney housing value

Real estate value could fall by 7.4% for Sydney's areas where littering is clearly seen, according to a new report.

According to the Sydney Morning Herald, Boomerang Alliance's report found that even if only 1% of the 1.6 million houses in Sydney were affected by rubbish, it could also have an economic impact of $ 11.8 million in the housing sector. The alliance is based on the model developed by the National Association of Housing Builders to draw the above results. This model determines that garbage near the house may cause the house to depreciate by about 7.4%.

"It is important to control waste in cities like Sydney, where the population is expanding and the environment is under pressure," said Jane Fitzgerald, executive director of the real estate council, NSW.

Boomerang Alliance convenor and director Angel Angel said that NSW made a historic decision to recycle containers, but did not make a historic decision on the use of plastic bags, did not take into account the plastic bags and plastic particles on marine life great influence. "Some smaller states and territories have already acted to know that all state governments in 2005 have announced that they have taken 1.5 billion plastic bags to be thrown away, of which more than 600 million have been thrown in NSW. "

Although the number of garbage in New Jersey is reduced by 12%, it is estimated that this year, Xinzhou throws 185 million plastic bags. The Boomerang Alliance, representing 45 community groups and more than 45,000 people, submitted the report to urge the NSW government to take action on product bans, recycling programs, up-regulation of waste disposal fees and mandatory design requirements. "Prevention is better than cleaning," the league said. The less the cost the better.

Mark Speakman, the head of the state's environmental ministry, said their primary task was to implement a plastic recycling such as ps foam containers recycling program and to study the issue of throwing plastic bags.

The domestic plastic market price has a slight fluctuation

It is understood that over the past decade, China's imports of solid waste (waste plastics, waste paper, scrap metal, etc.) total more than 500 million tons, the average annual imports of raw materials used to achieve nearly 50 million tons of waste.

Among them, the United States as China's largest importer of solid waste, according to the United States Waste Metal Recycling Industry Association (ISRI) statistics, in 2016 China imported from the United States worth $ 5.6 billion in scrap metal products. In addition, China has imported US $ 1.9 billion in waste paper (totaling 13.2 million tons) and US $ 495 million of waste plastics (1.42 million tons) from the United States.

However, according to the Ministry of Environmental Protection issued the "2016 National Large and Medium City Solid Waste Pollution Prevention Annual Report" shows that imports of waste 46.98 million tons in 2015, compared with 2014 imports decreased by about 5.3%. Engaged in the import and export of waste processing enterprises 2142, compared with 2014 decreased by about 7.6%.

In the halt of four types of solid waste imports, the domestic solid waste market will become the only source of recycling enterprises, the domestic supply can fill the gap?

First, a group of data, 2015, 246 large and medium cities in general industrial solid waste production amounted to 1.91 billion tons, of which the comprehensive utilization of 1.18 billion tons, the disposal of 440 million tons, storage capacity of 340 million tons, dumping volume of 170,000 tons.

"Prohibit the import of China's overall plastic foam recycling industry does not have much impact on the short term may be specialized in the import of waste plastics enterprises may have a certain impact, long-term lack of China's domestic waste plastics industry can promote the development." Chen Jianping said that the next step Need to strengthen China's domestic solid waste recovery system system to improve the work.

As for the price, a number of enterprises engaged in the import of solid waste introduced, prohibited imports, the domestic solid waste market prices may have small fluctuations, but the original domestic market prices are continuing to decline, the scale of domestic solid waste is also Large, long-term will not affect the market price.

Transparent plastic cups, packaging foam is made of polystyrene

   Polystyrene (commonly known as benzene) refers to the styrene monomer by free radical polycondensation reaction of the polymer, the English name for the Polystyrene, referred to as PS, belonging to a polyolefin.

    The material is resistant to vibration, moisture, thermal insulation, sound insulation, light weight and other characteristics, widely used in building wall insulation, electronics, electrical appliances, cold storage, greenhouse, storage and solar energy and other applications. The main use of the characteristics of polystyrene to create a variety of insulation sheet, EPE (polyethylene foam) foam packaging products. For ordinary type, flame-retardant foam flat, to undertake all types of electrical appliances, pipes and fragile items design and packaging.

    Transparent plastic cups, packaging foam is made of polystyrene. Polystyrene can also be copolymerized with other rubber types of polymer materials to produce a variety of different mechanical properties of the product, the daily life of the common application of a variety of disposable plastic tableware, transparent CD box and so on.

    As polystyrene foam tableware cheap, convenient, in line with business profit requirements and fast-paced life trend, but also to prevent disinfection caused by cross-infection accident, has long been a fast food preferred packaging containers. However, this tableware is not easy to use in the natural environment after degradation, coupled with poor management of the environment and people's awareness of environmental protection is weak, the waste was arbitrarily discarded the phenomenon is quite common, so as to the city landscape, the ecological environment caused serious negative influence, the image of the metaphor for the "white pollution", which triggered a new environmental problems. So, we should think the styrofoam disposal to deal with the problem. With the social production and life continue to move forward, the severity of ethylene foam tableware escalating.

        Burning will produce a lot of carbon monoxide or carbon dioxide, resulting in harmful gases can cause personal poisoning. In the warm industry, polystyrene is often used as a warm insulation material. Long in a high temperature environment, the polystyrene will quickly deteriorate, and will release formaldehyde, free benzene and other harmful to the human body, serious also cause cancer.

The filling processes must satisfy product highest quality requirements

With the increase of the living standard, People have more choices of food. Usually people would like to choose fast food which are packed in disposable plastic containers, so this kind of food contributes to the development of food filling. Food and beverages filling systems means the process of filling product of food and beverages with different materials.

The piece of equipment used by people to fill product into containers is called the filler. Different kinds of food and beverages are filled with such as beer, wine, edible oils, dairy products, fruit juices and soft drinks. Liquid filling systems have evolved in the last decades with the appearance of aseptic technology. They were first introduced in the earlier years with the introduction of the carton packaging. Filling is done in several equipment such as PET bottles and other plastic containers. The filling processes in particular must satisfy product highest quality requirements.

The global market of food and beverages filling system is driven by escalating consumer trends for packaged food. Nowadays, most people consumed packaged food, so filling system is required to improve with the latest upgraded methods and technology. The market is very competitive and the market players are spending more on the product development and innovation to meet and drive consumer demand.

Different systems and different technologies may be used. On the basis of process, the global food and beverages filling systems are divided into manual, semi-automatic, and automatic. In manual process the entire process is carried out manually, whereas semi-automatic process is carried out manually as well as with the help of machines, whereas automatic process is carried out by the machines.

Alone with the fast continuous development and improvement of food and beverage filling system, plastic containers and trays are also produced in a large scale. These plastic containers provided people with convenience, but people are always throw waste polystyrene products away. This causes the serious white pollution of the environment. Not only the discarded plastic waste a large sum of money in producing them and dealing with them such as polystyrene recycling, but also they result in environment pollution.

  

Bug eat plastic bags: clearing white pollution has new hope

Wax is a common insect larvae of large wax borer. Wild wax moth parasitic in the colony, the whole of the European honeycomb is a scourge. Wax moths lay eggs in the hive, and their larvae rely on beeswax hatching and growing - wax moths and hence the name.

Bertocchini came from the Colombian Institute of Biomedical and Biotechnology (CSIC) in Cantabria, Spain, and co-author Paolo Bombilli, and Christopher Howe of the Department of Biochemistry at Cambridge University. They brought about a hundred waxes into contact with a plastic bag in a supermarket in the UK, and only 40 minutes after the bag began to appear on the bag, and 12 hours after the weight of the plastic bag than the beginning to reduce the 92 mg.

The study was published on April 24 at Current Biology. Paolo Bombelli, Cambridge University's first author, Cambridge University, said: "If only one enzyme in this chemical process works, then the use of biotechnology to replicate the process should be feasible, the recycling through polyethylene densifier may become an important tool, which can help us clean up the landfill and the accumulation of polyethylene plastic waste in the ocean.

Polyethylene is widely used in packaging, accounting for 40% of the total demand for plastic products in Europe, of which 38% will be discarded to the landfill. People around the world consume about one trillion tons of plastic bags a year. In general, plastic is extremely difficult to break down, even smaller debris is difficult to be degraded by the ecosystem. So it caused serious environmental damage. While nature may be able to provide a solution. Beeswax is a mixture of a wide variety of lipids, and lipids are key molecules that make up the biological cells of fat, fat and certain hormones.

China has take actions to save the energy-efficient buildings vigorously

In recent years, China has actively take actions to save the energy and develop energy-efficient buildings vigorously. So polystyrene foam plastic (EPS) industry has developed rapidly, it is currently the most widely used material which the quantity  demanded highly increases. The trend of industry development are getting better and better.

Polystyrene foam production is concentrated in the Northeast area of China and in Jiangsu, Zhejiang, Beijing, Tianjin, Hebei provinces. Small and medium enterprises are the majority. In 2007, 2008, 2010, 2011, 2012, there were five insulation molded polystyrene foam tests, the product qualification rate were respectively 95.1%, 96.3%, 97.5%, 97.5%, 97.8%. Product quality is steadily improved, but there are still some problems. The main problems focused on the apparent density, oxygen index, burning grading. The latest test found that a batch of products from Wuhan Xingda insulation material factory are unqualified for their apparent density.

When the density of polystyrene foam board is insufficient, if it is used for building exterior insulation, it will lead to its low tensile strength which can not meet the requirements of both its weight and insulation system, so it will be easy to make polystyrene board be pulled off from its central part; while the insufficient density will result in the reduction of insulation, increasing moisture absorption, affect the  effect of the building insulation. In a word, polystyrene foam board will not achieve the effect of energy-saving building insulation.

At the present, the amount of styrofoam manufacturing enterprises in China is about 2000, the quality continues to increase. Although the large usage of polystyrene, the polystyrene are disposable, which can easily become the white pollution, so recycling through foam densifier is very necessary to protect our environment. And then we can reuse it to do some other products.

Disposable lunch boxes are popular among people which may cause pollution

Disposable lunch boxes are popular among people because of the convenience, and people can see the boxes anywhere. Currently, most of the disposable lunch boxes at the market are made of polystyrene which are refined from petroleum and polystyrene foaming agent, then heating and foaming. Polystyrene is a kind of widely used polymer materials, with the lower toxicity, higher melting point, easy plasticity and simple production, so it becomes the first choice of materials for disposable lunch boxes.

Disposable lunch boxes from the original foaming type to the present biodegradable type, its application continuously increased. Office workers and students are the major people to use disposable lunch boxes. From the aspect of health or environment, most people know that disposable lunch boxes have a lot of controversies. However, it is still being used due to its convenience. Experts remind people that the disposable lunch boxes in the supermarkets are not all in line with national standards, long-term use of substandard lunch boxes does harm for the body. It is better to prepare one’s own lunch box.

Disposable plastic foam lunch boxes, also known as disposable polystyrene foam lunch boxes. Wherein the disadvantages of the raw materials on the human body can not be underestimated. If polystyrene is heated, it will release harmful substances, people can eat them with the food, and it harms people’s central nervous system, kidneys and liver, and even cause cancer, so the long-term use can increase the risk of illness. So, plastic recycling through Styrofoam hot melting machine is a good way to deal with it.

Most people would think white lunch box is clean and sanitary, but degradable lunch box is not the same. The general selection of the material for the biodegradable lunch boxes are paper and plants, and neither the color of the paper nor the plant is white, even the paper we used everyday has also been bleached. Lunch boxes made of starch are gray, other types of lunch boxes are also slightly darker instead of pure white. Lunch boxes may also be added a number of qualified additive in order to make the production look better. Some substandard disposable lunch box itself has a certain pungent odor, which is due to the process of adding a number of harmful chemicals or industrial additives in the boxes. Texture qualified box itself should have a certain toughness, not very crisp and can’t be broke with a poke, it should have high intensity.

The effects of micro plastic beads on human health is serious

 The effects of micro plastic beads on human health will be investigated by the most senior medical advisers. Experts are concerned that plastic beads used in cosmetic products are being flushed down plugholes and later eaten by fish and shellfish.

  The contaminated marine life is then consumed by humans – with potentially dangerous effects on the body.Scientists fear that the beads contain harmful chemicals and may also be a magnet for pollutants in the sea.

  Relevant environment researchers announced plans to ban the micro plastics – which appear in products from face washes to toothpastes – earlier this year after the Daily Mail took up the issue with the Ban the Beads campaign. Now officials are taking an important further step by ordering research to establish the level of the risk posed to human health.

   Experts have estimated that several tons of plastic micro beads are used around the world every year. A single shower can result in up to 100, 000 plastic particles entering the sewage system. The torrent of micro beads pouring into the sea means that more than one in three fish caught by trawler in the seas contained plastic particles, according to the study.

   Based on current estimates, the level of human exposure is likely to be low, but most people would probably prefer not to be eating plastic with their seafood. There is an urgent need for more research into the impact on human health of micro plastics, as well as their impact on the environment.

   Several studies show that micro plastics are present in seafood sold for human consumption, including mussels. The presence of marine micro plastics in seafood could pose a threat to food safety. However, due to the complexity of estimating micro plastic toxicity, estimations of the potential risks for human health posed by micro plastics in foodstuffs is not yet possible.

   So it is very necessary for people to find some ways to solve the problem. Recycling plastic waste through foam recycling machine is very important. Many cosmetic factories should ban or reduce the use of micro beads in their products. Besides, some recycling companies are professional in solving this kind of problem. Recycling methods is very helpful to reduce the pollution.

Take-away food and packages has caused a lot of pollution

During recent years, with the rapid development of take-away food and packages, people are used to applying polystyrene or styrofoam products in daily lives. Though these kinds of plastic products do provide people more convenience and save people’s time, it really also brings some bad effects such as serious environment pollution.In order to solve the problem, more and more people are aware of the significance of foam recycling and take actions.  

Some recycling companies accept waste foam at its warehouse facility and offers customers with the location where they picked up these foam scraps.These companies also provide foam recycling equipment rental, which aims at the regular recycling program. Along with the rental, they offer some relevant services such as free recycling cost assessments, especially for organizations which collect large quantities of foam scraps.

Foam usually refers to EPS (expanded polystyrene, commonly known as Styrofoam), it has become a significant source of waste for many manufacturers and distributors. However, people do not need to worry too much about this kind of pollution because it is recyclable.

Recycling companies have developed efficient and cost-effective methods for companies to get rid of extra unwanted foam waste which can be manufactured into recyclable products such as particles.

There are many different kinds of foam recycling machines can process the waste foam such as foam compactors, foam melting machines and foam shredders. The compactors press and compact the foam into solid logs, the melting machines apply thermal method to melt the foam and the shredders cut the foam into strips or foam beads.

Expanded Polystyrene has some information that we should know

Expanded polystyrene (EPS) is a rigid and tough, closed-cell foam. It is usually white and made of pre-expanded polystyrene beads. EPS is used for many applications e.g. trays, plates, bowls and fish boxes. Other uses include molded sheets for building insulation and packing material ("peanuts") for cushioning fragile items inside boxes. Sheets are commonly packaged as rigid panels, which are also known as "bead-board".

Due to its technical properties such as low weight, rigidity, and formability, EPS can be used in a wide range of different applications. Its market value is likely to rise to more than US$15 billion by 2020. However, the expanded polystyrene are disposable, which can easily become the white pollution, so eps recycling is very necessary to protect our environment. And then reuse it to do some other products.

Thermal conductivity is measured according to EN 12667. Typical values range from 0.032 to 0.038 W/(m·K) depending on the density of the EPS board. The value of 0.038 W/(m·K) was obtained at 15 kg/m3 while the value of 0.032 W/(m·K) was obtained at 40 kg/m3 according to the data sheet of K-710 from StyroChem Finland. Adding fillers (graphites, aluminium, or carbons) has recently allowed the thermal conductivity of EPS to reach around 0.030–0.034 (as low as 0.029) and as such has a grey/black color which distinguishes it from standard EPS. Several EPS producers have produced a variety of these increased thermal resistance EPS usage for this product in the UK & EU.

ICC-ES (International Code Council Evaluation Service) requires EPS boards used in building construction meet ASTM C578 requirements. One of these requirements is that the oxygen index of EPS as measured by ASTM D2863 be greater than 24 volume %. Typical EPS has an oxygen index of around 18 volume %; thus, a flame retardant is added to styrene or polystyrene during the formation of EPS.

The boards containing a flame retardant when tested in a tunnel using test method UL 723 or ASTM E84 will have a flame spread index of less than 25 and a smoke-developed index of less than 450. ICC-ES requires the use of a 15-minute thermal barrier when EPS boards are used inside of a building.
