The Management of Waste Foam Polystyrene

Reduce the foam polystyrene packaging waste, there are four main methods:

A) Reduced use - it refers to the reduction in the consumption of natural resources. To this end, avoid the use of disposable products, and improve the packaging design, reduce the use of foam polystyrene materials to reduce environmental costs and environmental load.

B) Waste utilization - Foam polystyrene packagings can be used multiple times, such as containing semi-finished products for internal transport. Another simple way to reuse a foamed polystyrene package is to crush the wrapper as a clay of the regulation, adjust the soil to the water and sparse characteristics.

C) Recycling - reprocessing the used foamed polystyrene packings to produce new materials as alternatives to other materials, such as replacing solid wood, making garden equipment, or replacing slate for paving roofs; or for the production of new plastic products such as hangers and CDs / cassettes.

D) Recycling - Foam polystyrene has a higher calorific value than coal, and can be safely combusted in a thermal recovery system or an incinerator with appropriate pollution control equipment, without releasing toxic or environmentally hazardous substances. So, Styrofoam recycling is greatly helpful.

Whether a product is environmentally friendly is to be considered from each stage of the product process, by the selection of raw materials and production processes, as well as the use of the product and the final disposal. For example, most people think that paper cups are more environmentally friendly than the sparkling glue cups. In fact, the steam and electricity required to make the vials are 12 times and 36 times smaller than the paper cups.

However, styrofoam and other plastic waste, like, is not easy to degrade, and will occupy the landfill space for many years. As with any other disposable or packaged material, the abuse of disposable styrofoam food containers increases the amount of waste disposal and puts pressure on landfills.

Waste carton packaging can also be recycled to do other products

We all have drank many brands of milk, fruit juice, tea, etc., but do you know that the packaging cartons of these products are valuable resources which can be recyclable? Take Tetra Pak as an example, Tetra Classic Aseptic is a material made of paper, aluminum foil and polyethylene plastic, of which with high quality pulp, aluminum and plastic content of about 75%, respectively, 5 % and 20%. The package has a total of 6 layers, which can effectively block all the factors that affect the deterioration of milk and beverages "invasion". After the use of Tetra Pak, each ton can be recycled about 600 kg of pulp, 200 kg of aluminum plastic raw materials, through the use of renewable processing, can be made of recycled paper, stationery, pallets, desks and chairs, trash and other Supplies.

At present, the recovery of such packaging mainly depends on the sanitation system, community cleaning staff of the centralized collection, but because of its recycling value less known, most of the use of beverage cartons after use has not been well recovered, virtually waste a lot of useful resources.

At present, Tetra Pak recycling which can recycle Styrofoam better and recycling technology there are three: First, the hydraulic regeneration of pulp technology, the Tetra Pak will be separated from the pulp, the production of recycled paper, and one of the aluminum foil and plastic ingredients into a grain, become Plastic materials, plastic products, Tetra Pak itself contains high-quality paper fiber and plastic, crushed them, can be directly produced into indoor furniture, outdoor horticultural facilities, industrial trays and other plastic products; Third, the color music board technology: Tetra Pak will be directly crushed, according to hot-pressing treatment to made of board, and then processed into a leather box and other beautiful and durable products.

Recycled polystyrene can also be used to do other products

Polystyrene, referred to as PS, which is a thermoplastic material, at room temperature for the glassy solid, if the heating is higher than its glass transition temperature will show a dynamic state, when the temperature will once again form a solid. Pure polystyrene solids are colorless, hard plastic and can be mixed with a variety of dyes to produce different colors. Solid polystyrene is widely used, such as disposable tableware, plastic models, CD and DVD housings. Expanded polystyrene is almost ubiquitous in everyday life, like packaging or beverage cups.

Polystyrene was first produced in Germany in 1930, and then in 1937 the United States began commercial production, the real development is the Second World War, that is, after 1946. At present, polystyrene in the world of thermoplastic resin, the output ranked fourth, after the polyethylene, polyvinyl chloride and polypropylene. At present, the world's styrene series of resin varieties have 30 to 40 species, nearly 100 brands, more than 400 kinds of grades, the output of 11 million tons / year, while polystyrene accounted for about 65%.

Polystyrene can be recycled and can be seen on recycled plastic 6, but polystyrene is not easy to recover because of its low weight and low recycling value, people generally do not cooperate with the recycling program, but in Germany require the manufacturer to bear The responsibility for recycling and disposal of any packaging materials.

On the other hand, the industrial polystyrene recycling has made great progress, many different methods have been developed. However, most polystyrene products are not recovered at present, due to the lack of adequate recycling facilities and collection methods. If polystyrene is properly burned at high temperatures, it will only produce water, carbon dioxide and some volatile compounds and charcoal, and the released heat can be used as a power for steam and power generation. If the combustion does not have enough oxygen or lower temperature, will produce polycyclic aromatic hydrocarbons, carbon monoxide and styrene monomer.

Whether Styrofoam Foam Board Toxic or not?

In recent years, floor heating in North China region has been rapid development, and because of its advantages such as it can save energy, protect environment, getting the local departments’ agreement. Many families have used this kind of foam board. But many households still have such worries - is polystyrene foam board toxic?

According to the information, pure polystyrene plastic foam board is not toxic, benzene board only to reach the combustion temperature or sustained high temperature will be harmful to people. However, the heating temperature will not exceed 60 ℃, so the special benzene board for floor heating will not constitute a direct threat to the human body. And the consumers cant use it safely.

In addition, the special benzene board for floor heating is not the active benzene, which is harmless to the human body. The fast food box used in the past, and fruit, seafood and other incubators which is used now are all processed by benzene. Solid benzene is harmless to humans. But we should reminded the vast number of consumers, some polystyrene plastic foam board manufacturers in order to improve their product performance, may be added plastic additives to improve the performance of polystyrene plastic foam board in the production process. And the additives can not be a reliable guarantee that it is harmless.

In addition, there are some irregular manufacturers on the market. In order to obtain more profits, they use a lot of waste plastic as a warm special benzene production of raw materials, which makes it difficult to ensure that its products are non-toxic. It is recommended that the vast number of consumers and to the enterprises to use the products which produced by regular manufacturers.

The manufacturer should keep integrity to produce the high-quality products. And we can recycle the waste plastic such as Styrofoam recycling in order to protect the environment. And then we can reuse it to do some other products.

More and more express packaging were threw away everywhere

Online shopping not only facilitated people's production and life, it also activated the electricity and express delivery market. However, it also brought the problem of "garbage piles". And this garbage is composed of cartons, tape, fillers and other components together after the unpacking of the express package. the recovery of these packages is difficult, and it will also pollute the environment.

According to the State Post Bureau statistics show that, in 2015, the national express consumption were 2.66 billion woven bags, plastic bags were 8.26 billion, 9.9 million packaging, tapes were 16.95 billion meters. Last year, the number of express delivery has exceeded 30 billion, there was no doubt to prove that the number of express delivery become increasingly huge, and the waste become more and more.

In fact, many people concern about the reasonable recovery of courier packaging.  There are five representatives of sanitation workers attended to the two sessions are also deeply touched. When they are in an interview, they often said that the packaging recycling such as Styrofoam recycling is a big problem which the government should think ways to solve the problem. Moreover, in the process of consultation, the reporter also learned that some representatives of the proposal is directed at express packaging.

The representative from Jilin put forward the proposal on solving the online shopping package waste. She mentioned a set of data in the proposal, the production of a ton of express box cardboard need to use 20 trees which aged 20-40 years; a no more than 50 grams of ordinary courier boxes need to consume 2000 grams of water and wood.

And the representative from Zhejiang put forward on the promotion of express delivery packaging green development proposal. She said with the data that the statistics show that 55.6% of consumers get the packaging after the packaging is discarded, the actual recovery rate of cardboard and plastic ares less than 10%, in some developed countries this data is up to 45 %.

So, the government should solve this problem rapidly to protect the environment and also save the resources, and recycling such as Styrofoam recycling is a good way to deal with the problem.
