Waste polystyrene plastic recycling should be took

Waste polystyrene recycling technology generally hot air heating, friction heat and other methods to melt, reduce the volume, in bulk or granular recovery, can also be recycled EPS particles and new particles mixed with, but in the process of heating shrinkage, due to Oxidation will result in the reduction of plastic properties, coloring, recovery costs and other issues affecting the quality of the newly developed Reno system with natural solvent limonene dissolved in the regeneration treatment equipment to filter, separation of solvents, granulation, made of recycled polystyrene the polystyrene regenerated in this method can be used as a raw material for EPS, in addition to the raw materials for injection molding and extrusion molding.

The use of PS soluble in aromatic hydrocarbons, halogenated hydrocarbons and other organic solvents, the nature of the PS foam can be made of paint or adhesive. Some manufacturers have experimented with PS foam and benzene, kerosene by a certain percentage of mixed and then add the right amount of inorganic filler and inert materials made of modified waterproof material. The use of PS can be dissolved in the nature of asphalt and rosin, with waste PS foam to change the melting point of asphalt, can improve the strength of asphalt and improve the asphalt winter crack summer sticks and overcome the shortcomings of rosin brittle and so on.

Non-solvent heat medium defoaming recovery process of recycle polystyrene is a result of a wide range of comparison and exploration after the current and abroad at home and abroad all the different ideas of thinking another idea, that is, non-solvent heat medium defoaming capacity of the process, discard the discarded polystyrene foam into the defoaming tank while adding a heat medium heated to a temperature to contact the waste foam and fall into the heated tank together with the defoaming material that is defoaming, and then And then defoamed the material and the use of the media separation, can be defoaming recovery material, if the defoamer seal, to achieve pressure operation, the whole process of time for 30-50s.

Due to the absence of reaction and solvation, and the low temperature treatment of defoaming polystyrene foam macromolecular structure and performance is not damaged, the defoaming of the material can be powder into granular, which easy to transport and use.

Expanded Polystyrene Foam Tablets and Other Marine Garbage

Floating garbage in the marine is mainly foamed polystyrene foam sheet, plastic bags and plastic bottles. The average number of litter and parcel floating debris is 30 per square kilometer; and the average number of floating litter in the middle and small blocks is 2206 per square kilometer and the average density is 20 kilograms per square kilometer. Polystyrene foam is the largest quantity of waste plastic, accounting for 46%, followed by is the plastic foam outside this object, accounting for 31%. In other words, a total of plastic is 77%. 91%  of the surface litter is from land-based and 9% is from ffshore.

Submarine waste mainly for plastic bags and plastic bottles, the average number is 720 / km², the average density of 100 kg / km². The largest number of plastic garbage is accounting for 84%.

Beach garbage is mainly plastic bags, expanded polystyrene and plastic bottles and so on. The average number is 50,142 per square kilometer and the average density is 3119 kilograms per square kilometer. Plastic garbage (not including foam) the largest number, accounting for 49%, followed by polystyrene foam, accounting for 22%. The plastics category accounts for 71% of the total beach waste. 86% of beach waste comes from land, and 14% from the sea activities.

In view as these situations, we should take actions immediately to protect the marine. The plastic recycling may be a good way. After we recycle these waste plastic through polystyrene compactor, we can process and reuse them. EPS can easily be recycled into new foam packaging or durable consumer goods like cameras, coat hangers, CD jewel cases and more. You can recycle your EPS packaging by taking it to a specified drop off location.

The recovery and utilization of EPS that we should know

Developed polystyrene EPS in the domestic rapid development, widely used in a variety of shock packaging, construction, decoration, tableware and so on. But most of the EPS packaging is a one-time consumables, after the waste is not easy to self-degradation, causing great pollution to the environment. Therefore, the development of EPS recycling, rehabilitation, regeneration has become the most pressing issue of the current EPS packaging industry. In recent years, China's recycling of EPS waste has been the attention of the relevant departments, government and other departments to strengthen the macro guidance and orderly management, the corresponding regulatory guidance and policy support policies have been introduced, people's awareness of resources and environmental protection has improved. On the whole, China in the EPS recycling has made no small achievements. For example, waste EPS after processing production XPS, has become the main way of domestic EPS recycling.

Waste polystyrene foam products recycling, not only can protect the environment, save energy, but also has a very good economic benefits.

And how to recycle eps is also a problem. EPS recovery methods are generally the following:

⒈ simple buried; this law workers, an area, and does not produce benefits.

⒉ as a fuel for burning; this method can produce heat, but the investment.

⒊ use EPS recovery granulation equipment, after hot melt regeneration granulation, EPS will be generated into PS particles. And then can also be heated by adding foaming agent, flame retardant, nucleating agent and other additives, processed by the system obtained XPS, widely used in building materials. At present, this recycling technology in the country has been a large area of ​​promotion, and become EPS recycling one of the main ways.

4. Other methods, such as the manufacture of rust-proof paint, the manufacture of multi-functional resin, the manufacture of anti-seepage fill agent, asphalt enhancer.

The National Key Research Program focuses on micro plastics for the first time

China is the world's largest producer and consumer of plastics, and micro-plastic pollution on China's coastal ecosystems constitute is a serious threat. However, scientists know little about the status quo of micro-plastics in China's coastal marine environment and its complex behavior in marine ecosystems, lack of risk assessment. Compared with foreign countries, domestic micro-plastic-related research is still relatively sporadic, micro-plastic distribution and sources of basic facts are not clear, the public also know little about micro-plastic.

East China Normal University, the State Key Laboratory of Estuarine and Coastal Sciences Shihua Hong revealed that a marine fish from China survey shows that more than 20 kinds of high economic value of the common fish sampling, 90% of the fish samples are found in the micro plastic. For marine life, micro-plastic like the ocean PM2.5, increasingly threatening their survival safety.

In 2013, our scientists began to pay attention to marine micro-plastic pollution related research. The National Key Laboratory of Estuarine and Coastal Research of East China Normal University first carried out the study of micro-plastic pollution in the Yangtze River estuary and the East China Sea, and then studied the marine micro-plastics in the coastal coastal areas of the coastal areas of China and several estuaries in the east. The results show that the number of microficans in seawater In the sample taken to occupy more than 90%.

The results show that micro-plastics have been widely found in the estuarine and coastal waters of China, and the river input has a significant effect on the micro-plastic content of the offshore sea. There are scientific research personnel to study the lower reaches of the three Gorges Dam, the South China Sea sediment and Hong Kong beach and other areas of micro-plastic pollution status, as well as the beach micro-plastic adsorption of organic pollutants and so on.

So, in our daily life, we should pay more attention to recycling styrofoam, through this, we not only can protect the environment, but also can reuse the waste resources.

What is the thermoforming condition of expanded polystyrene?

Expanded polystyrene can also as the raw materials of thermoforming, it is commonly used in the manufacture of packaging containers and short-term insulation containers. Products are characterized by small density, good insulation, which is due to the very poor thermal conductivity of this material,. When in the molding, the heater temperature should not be higher than 340 ℃. In order to achieve the necessary molding temperature, heating time can be extended to be remedied. If you use extrusion feeding, without secondary heating, which may be in an ideal condition. In addition, when heating, due to the foam plastic (sheet) material will be further expanded, easy to wrinkle when molding, should be paid special attention. If foamed polystyrene sheet material in good thermoforming performance, we can use ordinary vacuum forming equipment and mold molding.

There is an example of a thermoformed fast food box which made by expanded polystyrene sheet is shown below.

① Expanded polystyrene board material which tensile strength of 1.1 ~ 1.2MPa; heat resistance at 100 ℃, 10min shrinkage ≤ 2.5%, at 60 ℃, 20min shrink ≤ 1.5%; health performance in line with national standards (1), the thickness of 1 ~ 4mm; GB 8689-1988 requirements.

② Foam polystyrene board material thermoforming lunch boxes. The use of temperature is -10 ~ 100 ℃; the tensile strength of 1.2MPa; elongation ≥ 10%; resistance to boiling water, no deformation; cold 30 ℃ no change; health performance in line with GB 8689-1988 requirements.

Thermoformed lunch box has excellent performance, especially its heat resistance, outstanding insulation performance, and clean, low price, so popular with business and has the vast number of consumers. It has become the main form of fast-food packaging.

After the use of these fast-food packaging, EPS can also be recycled which is called polystyrene recycling, and used for other purposes, such as frame products.

Foamed polystyrene waste can also be used to do other products

With the rapid development of petrochemical and plastic industry, plastic products have been widely used in industrial and agricultural and daily life. As the polystyrene (PS) after the foam has a low density (25 kg / m3), low water absorption, acid and alkali, good sound insulation, and shock, can be decorated, easy to shape, etc., so in building materials, household appliances aspects of a wide range of applications, but also caused a more serious white pollution, the recycling rate of less than 20%. Abandoned foam PS if buried, because it is not easy to aging and difficult to degrade, will pollute the underground water, destruction of soil structure, so that grain and other crops cut; such as simple incineration, it will seriously pollute the air and atmospheric environment.

In view of the above problems, people have to explore and practice the use of foamed polystyrene waste for chemical building materials industry, and achieved satisfactory results, creating a considerable economic benefits. And Styrofoam recycling is a good choice.

Application of Foamed Polystyrene Waste

1. Light roof insulation material

Crushed waste foam PS, adding expanded perlite and cement, mortar, and then  mixed after the roof placed on the maintenance of 3 days, naturally dry, and then with the cement mortar smooth into a lightweight concrete insulation layer. The method used to produce the material production cost is low, and has a good insulation.

2. Waterproof membrane

The waste foam PS wash, dry, with cheap benzene or chlorine hydrocarbon residue dissolved, adding toughening agent and film-forming anti-wear agent to reconcile into a viscose-like, blown or coated on the glass cloth surface, dry After the waterproof membrane, can be used for roof or pipe waterproof. The solvent can be recycled after cooling.

3. Fiber reinforced insulation board

The waste foam PS crushed into 0.1 ~ 0.5 cm particles, adding cement and fiber reinforced mixture, and fully mix, and conservation, can be made of excellent mechanical properties of lightweight sheet, it also can be pre-made into a composite wall, indoor insulation noise board, block, can also be used for on-site pouring.

Can plastic do something for overpacking?

Excessive packaging, with the words of experts is: packaging supplies too much, too heavy, the volume is too large, the cost is too high, too gorgeous decoration, saying that the word is too beautiful and so on.

Most plastic packaging only once, according to rookie network data, 2016 China Express more than 30 billion pieces, 12 billion plastic bags, 14.4 billion boxes, 24.7 million meters sealing tape - can be around the earth more than 600 laps, 95% of the value of plastic packaging materials have been lost, each year about 80 billion -1200 billion US dollars. Can you imagine that a plastic man looked at the white plastic flower (silver) material (child) was so alive and thrown away, his heartache index how high?

In the suppression of excessive packaging, we have to learn from Germany. German regulations require that the packaging volume of more than 10% of the product itself and packaging costs significantly beyond the 30% of the goods, should be judged as infringement of consumer rights and interests of the "commercial fraud", while Germany also set up a traditional plastic bag levy 1.27 euros / Kg of tax, fully biodegradable plastic bags tax free.

The world is emphasizing environmental protection, and new plastic people, of course, have to use new ways to do plastic, from the source to stop the "one-time" - to improve recycling, increase the reuse of packaging, biodegradable packaging use.

In fact, our daily life often used in more than 10 kinds of plastic, such as polyethylene (PE), polypropylene (PP), polyester (PET), nylon (PA), polyvinyl chloride (pvc), polystyrene Ethylene (PS) and so on. In principle, all thermoplastics can be recycled several times, but the recovery process conditions are different. Such as nylon can be made into car decorative cloth, polystyrene waste plastics can be recycled into outdoor chairs. If we take such action as recycling styrofoam, then the waste plastic will not have to bury or incinerate. It is a good measure to protect the environment. And we can also reuse the resources to do other products.

Green Buddy has Launched Natural Decomposition Plastic Bags and Lunch Boxes

Green Buddy, which is currently regarded as the first brand of natural environmental protection plastic bags, is also active to reduce the target of white pollution. The director of Green Buddy said that the purpose of their environmental awareness is to reduce ecological pollution and contribute to the ecology of the planet. Through sustainable market education and development and promotion of environmentally friendly related products, to create a green planet, so that people enjoy a happy and happy, happy living environment.

Plastic bags were randomly discarded, plastic bags did not collect properly handled, the foam packaging was arbitrarily discarded, plastic waste caused by urban pollution, has also seriously eroded the surrounding environment we live in, and plastic recycling such as polystyrene recycling is also very difficult to doing.

Located at the Kota Kinabalu's Garbage Landfill, the city's garbage disposal is up to 800 tons a day. The 115-acre landfill is filled with all kinds of rubbish and needs to be met as soon as possible.

Plastic bags to bring people and the environment hazards, including the drainage system caused by flooding, soil pollution crop loss, waste incineration pollution of the air, incineration of waste caused by haze harm health, marine pollution caused by marine biological death and other serial issues.

The benefits of natural decomposition, so that every day discarded plastic bags can be quickly decomposed in a very short period of time, which is a great help to reduce the white pollution. Our products use the international standard certification of natural decomposition of environmentally friendly raw materials additives to ensure that these environmentally friendly plastic bag discarded within 12 months after the heat in the sun and after the oxidation process for microbial bite into small pieces, and the excreta of the microorganisms will also be the necessary nutrients, so that the earth's ecology is no longer subject to traditional plastic pollution.

Towards a global treaty on plastic waste

Solving plastic pollution is not easy; alone, a country or a company, how can not work alone to solve this problem. There must be a large number of actors - including the largest plastic producers and polluters, zero waste plans, research laboratories, waste recycling agencies, etc. - to deal with this problem.

The first step is to establish a high-level forum to facilitate the discussion among these stakeholders in order to develop a cooperative strategy to reduce plastic pollution. This strategy can not be confined to voluntary action and cooperation programs, but rather to the development of legally binding international agreements based on governments' commitment to eliminate plastic pollution. The negotiations for the treaty could be launched at the UN Environment Conference in Nairobi in December this year.

Scientists have put forward specific proposals for a plastic pollution treaty. One of the authors of this paper presents a convention that follows the Paris climate agreement: a binding primary goal is combined with a voluntary national action plan and a flexible means of realization. The research team at the University of Wollongong, Australia, is inspired by the Montreal Protocol for the Protection of the Ozone Layer, suggesting that restrictions and prohibitions on new plastic products should be adopted.

Some may ask whether we should open another long, tortuous and tedious global negotiating treaty. Can not we find a way to solve the plastic problem?

The simple answer may be "no". For example, biodegradable plastics are only meaningful if the degradation rate is fast enough to avoid damage to wild animals. Even people looking forward to the discovery through a EPS recycling machine, such as the decomposition or digestion of plastic bacteria and moths, can only serve as a support.

The only way to really solve this problem is to cut off plastic waste. Technology may be helpful to provide more options for substitution and recycling; however, many of the world's zero-waste communities and cities indicate that this is not a must.

Plastic pollution is a distinctive feature of human discipline. After all, it is a global disaster that is entirely up to us - and we have the power to solve it.

What is styrofoam insulation recycling?

The main applications of polystyrene include insulating panels for floor, wall and roof applications of household and commercial buildings due to their light weight, strength and insulation characteristics. Polystyrene insulation provides a cost-effective, high-performance solution for the construction industry.

EPS, known as foam polystyrene, is well proven in civil engineering and construction applications, and its inherent strength means that it can easily support roads and rail structures.

Just like any other product, there will be substandard goods and spare parts. In construction, these are waste polystyrene. It is poor to throw them into rubbish and landfill, which can also cause white pollution. Therefore, polystyrene insulation recovery and polystyrene insulation recovery is necessary. However, since it is large, it requires large spaces to store waste polystyrene insulation and polystyrene foam waste.

Is there a solution that can help Styrofoam insulation recycling? Yes. GREENMAX recycling machine can come to help.

About the Styrofoam insulation recycling, INTCO recycling has a kind of compactor which can compact waste Styrofoam insulation into tight block, and help you to reduce the volume of Styrofoam waste up to 50:1. Because the compactor can smash the waste Styrofoam insulation materials into pieces by the blades and gears, and then it could be easily compressed into tight block. After compaction, the blocks can be reused to do other products, such as frame products and construction moldings. As a result, the pollution and resource condition will be improved and changed much.

Foam Cups are Recycled by Melting Machine in INTCO

In recently years, many fast food shops and coffee shops has offered paper-colored beverages, such as Starbucks, Kentucky Fried Chicken, McDonald's and so on, as well as most of the milk-tea shops along the streets also has provided paper drink cups. Recently, the media reported that China's annual consumption of disposable paper cups are more than 10 billion, which caused a bad impact on the environmental protection. And the recycling of disposable paper cups has become a big problem.

We know that although the outer paper cups are mainly made of white paperboard, the inside of the cup is a thin coating in the form of a layer of polyethylene plastic. The aim of it is to prevent the coffee cup soaked and lock the temperature of coffee. However, the thin layer of polyethylene plastic film is difficult to separate, so some recyclers do not willing to recycle it. Even if the paper cups can be broken and mixed with plastic to make low-grade cartons, which are used in shoe boxes, fruit boxes and other products. So, when these cups are discarded, they are ultimately be incinerated, which not only cause pollution, but also waste these resources. Therefore, some businesses are trying to reduce the use of disposable paper cups, or using other environmentally friendly paper cups to replace them.

Therefore, foam cups recycling has become an important way to solve the pollution it produces. About the problems of disposable cups recycling which has mentioned above, a melting machine, belonging to GREENMAX Recycling, can help you solve these problems. This machine can crush these cups first, and then after heating and extruding, these cups will become the densified ingots, with the volume reduction ratio up to 90:1. Because of it, the melted cups are easy to transport and will have little pollution on the environment. Then, we can reuse the resources to make other products. It provides great convenience to the recyclers. 

PS foam containers can be recycled

A foam container is a disposable container for a wide variety of foods, including beverages. Containers are usually used to take away food from restaurants, but also by asking diners to use the remaining meals to go home.

Polystyrene Foam is a trademark of Dow Chemical Company Closed Pore Extrusion Foam Polystyrene is currently used for insulation and process applications. The word is often mistakenly used as a generic term to expand (not squeeze) polystyrene foam, such as disposable coffee cups, coolers, or cushioning materials in packaging, which is usually white and is made of foamed polystyrene Beads.

The foam takeaway container is made of XPS foam, or another type of polystyrene foam, foam produced by injection into the mold. Foam fast food boxes come from different variants. These may include: a rectangular shape of the grab-style style container using additional cover, which comes from different sizes. Usually larger features of the number of cars, allowing different food to keep separate. This breed feature predicts a few small containers that are usually covered at the bottom through the slot "lock", thus preventing food spills. These also have a square print name for large organizations. On top of that, ps foam containers recycling can help to deal with this pollution.

A cylindrical container and a separate style, translucent or opaque plastic cover. The container may or may not be a little bottomed. Two overall size of the high diameter ratio is very different. This container usually holds soup and stew; however, smaller varieties are usually used to store seasonings and condiments.
