Recycling Plastic

This article was interesting to me when I read it at Buzzle.com

Plastic is a very common material that is now widely used by everybody in this world. Plastic is used in many ways as it is light weight and compact. The maintenance that is required is very less. Common plastic items that are used are bags, bottles, containers and food packages. Whenever you buy grocery, food or any other item from any store you will use plastic bags for carrying them.

The plastic material has many advantages. They are especially very useful for packaging foods as the plastic items are durable, safe and cheap. The ease of use of plastic items has made plastic a great success. The great problem with plastic is its disposal. Plastic is made of polymer chemicals and they are not bio degradable. This means that plastic will not decompose when it is buried. When plastic is burnt it emits harmful chemicals. Though plastic is a very useful material that is flexible, robust and rigid they become waste after their use and they pollute the atmosphere.

To protect the environment as well as to take advantage of plastic, recycling procedure is used. Plastic can be recycled and new products can be formed from waste plastic. Though all types of plastic cannot be recycled a considerable portion can be recycled so that the environment is protected. Plastic recycling involves the process of recovering scrap plastics and these waste plastics are then reprocessed to form new materials that may be different from their original state.

Recycling plastic has many advantages. The use of non renewable fossil fuels is reduced by recycling plastic as manufacturing new plastic materials require more of these fuels. The consumption of energy is also reduced as already prepared plastic are recycled for new use. The amount of plastic that reach the landfill sites are greatly reduced by recycling. This will eliminate land pollution to some extent. The carbon emissions are reduced by recycling plastic as manufacturing units emit more carbon..

Compared to other materials like glass and metal, recycling of plastic is expensive and complex. This is due to the high molecular weight of the large polymer chains that build the plastic material. Heating plastic doesn’t dissolve he polymer chains and hence a tedious and complex process is essential.

Different types of plastic cannot be mixed together for recycling because they phase separate. Such a resulting melting product cannot be recycled to make another plastic product. While making plastic product many fillers like dues and other additives are used. These fillers cannot be separated from the plastic using inexpensive techniques. This makes the recycling process more complex.

The common process that is used in recycling plastic is the inverse polymerization process where the polymers in the plastic are converted into initial monomers that were used in the manufacture. These chemicals are then purified and synthesized to form new plastic materials. Assorted polymers are converted into petroleum in another recycling process. The advantage of this process is that any mix of polymers can be used. A new recycling process generates heat from the friction of plastic materials which melts the plastics. This is then pumped into casting moulds. The great advantage of this technique is that all types of plastics can be recycled.

To aid the recycling process, plastics come with plastic identification code to identify the different polymers that are used in the manufacture of plastic. The recycling process must be started from home. When you have utilized that plastic item for its use you can use the same item for some other use. For example, if you buy a juice bottle you can use the plastic bottle as a storage container for reusing the pet bottle. Also everybody must be aware of the recycling plant in the locality and must produce the waste plastic to the plant for recycling.

PWB value dips slightly

The gross value of printed wiring board scrap retreated slightly in February to $5.21 per pound, down 2.7 percent from January’s record high. The year-over-year PWB value are up nearly 30 percent from February of 2009.

This data represents the full metallic values of boards over time and are not the recycling values, as those values do not include the costs involved in actually extracting metal from boards, including freight, sampling charges, assay assessments, smelting, refining, process loss, return on investment, and penalties for various elements, including beryllium, bismuth and nickel.

These values are for the estimated intrinsic metal content of recovered PC boards. Some consumers label such material as mid-value. Lower-value scrap includes monitor and television boards. Higher-value scrap includes network and video cards, and motherboards.

The average value of board scrap for the year is still strong at $5.28 per pound, a 37.1 percent improvement over the same period last year. Reported by E-Scrap News.

What is e-waste?

E-waste, discarded electronics, from computers to cell phones to TVs, are now the fastest-growing waste stream in the U.S. It is also big business: Hundreds of companies buy and sell the discarded components and materials, generating a $6 billion market in the U.S. But e-waste, which contains such toxics as lead and mercury, is often dumped illegally in the U.S. or shipped to developing countries by shady dealers.

ABI Research said that last year the market for e-waste recovery globally was around $5.7 billion. This revenue is described as money generated through reclamation of valuable materials from e-scrap. A number of factors drive this growth, including rising rates of e-waste collection and recycling, larger availability of more cost-effective recycling technologies and “the integration of formal and informal recycling markets in key Asia-Pacific locations.”

“The combined impact of the ongoing global economic recovery and strengthening e-waste recycling legislation worldwide will drive improved recycling/recovery rates in each of the next five years,” said ABI director Larry Fisher in a statement.
