Fortunately Loss Not Environmentally Friendly Plastics



Including plastic materials that are difficult to be recycled, can not even described. Is it true that plastic recycling spent more money than I did when making it?
In 1967, McGuire has one career advice to young Benjamin Braddock, which is plastic. In the 40 years since the 'graduation', the plastic explosive in many applications, ranging from bumper cars to computers, and classified into seven types.
Including PET # 1, the kind used for plastic bottles and soda water. Now, the question that arises is, what to do with all the plastic there. Of the 2.7 million tons of PET plastic bottles in the United States in 2006, four per limanya ends up in landfills.
Ignoring environmental concerns, economic success or failure of plastic recycling depends on two variables. Namely, the cost of raw materials to make plastics treatment, petroleum and natural gas.
In addition, the cost of recycling against the disposal costs that fluctuate based on the proximity of the city with recycling centers to dispose of and prices in local landfills is also taken into account.
The study results University of California, Berkeley estimates that areas like Los Angeles and San Francisco could receive the economic benefits of U.S. $ 200 (USD 1.7 million) per ton for recycling instead of disposal.
Even so, the cost of recycling bottles than making quite varied, depending on the bottle and the oil price swings. According to the environmental organization Earth Policy Institute, each year, 29 billion plastic water bottles are manufactured for use in the U.S..
Making plastic bottles are needed the equivalent of 17 million barrels of crude oil, so rising prices of oil and natural gas only exacerbate the high price of plastic. 'Plastic News,' trade magazine, listing the latest price of PET bottle resin pellets between 83-85 cents (Rp 7-7, 2 thousand) per pound.
However, the increasing price of plastics has a little curb demand. According to the National Association for PET Container Resources (NAPCOR), in the past two decades, the amount of PET plastic in the U.S. rose more than doubled. This increase is the result of surge in demand for bottled water.
In 2005, seven and a half billion gallons of water flooded the U.S., this number is equal to the average amount of water flowing over Niagara Falls for three hours. According to U.S. government data, the amount of bottled water was 21 times more than required in 1976.
All the extra plastic, and petroleum used to make, including expensive. NAPCOR estimates, 5.5 billion pounds of PET bottles to spread in the U.S. in 2006. Making so many bottles and jars from PET plastic is cost U.S. $ 4.5 billion (Rp38, 2 trillion) was only to raw materials, without the cost of bottle production plant operation.
Before being reincarnated into industrial carpet or sleeping bag, plastic bottles have a long journey ahead of him. First, this bottle into the collection facility to be examined contaminant, such as stone or glass.
Then washed and cut into pieces. These flakes are dried and melted into plastic lava droppings are filtered and formed into strands. Finally, the strands are cooled in water and cut into pellets that can be marketed.
Even so, the dump (landfill) is the final resting place of most of the bottle. As if this is a cheaper option. However, landfill disposal charge to offset the cost of creating, maintaining and closing the landfill that can be very expensive compared to recycling.
This is especially true in densely populated areas like the East Coast or Florida that has a shallow water table. In fact, according to trade publication editors 'Plastics Recycling Update' Jerry Powell, the cost could soar from U.S. $ 10 (Rp85 thousand) per tonne to over U.S. $ 100 (Rp850 riub).
According to the non-profit organization Container Recycling Institute, in 2005, PET bottles worth U.S. $ 500 million (Rp 4.2 trillion) into landfills. Rising prices forced some companies plastic bottle products, like Coca-Cola, think twice about using plastic resins are expensive.
Now, the company worked to make the lighter bottles that contain more recycled resin, Powell explained. The bottle is made using a thin plastic resin content of 30% less and rely on water or liquid in it to maintain its shape.
Using less resin per bottle could mean savings on raw materials around U.S. $ 1.5 billion (Rp 12.7 trillion) per year for the bottling industry. Powell considers it a positive step for the business and the environment. "That's what we need. Slightly plastic. Not just recycling, "he concluded.
