plastic bags can produce diesel

Plastic shopping bags, an abundant source of litter on land and at sea, can be converted into diesel, natural gas and other useful petroleum products, researchers led by an Indian origin scientist claim.

The conversion produces significantly more energy than fake rolex it requires and results in transportation fuels diesel, for example that can be blended with existing ultra low sulphur diesels an fake rolex d bio diesels, researchers said.

Other products, such as natural gas, naphtha (a solvent), gasoline, waxes and lubricating oils such as engine oil and hydraulic oil also can be obtained from shopping bags.

There are other advantages to the approach, which involves heating the bags in an oxygen free chamber, a process called pyrolysis, said lead researcher Brajendra Kumar Sharma, a senior research scientist at the Illinois Sustainable Technology Centre at University of Illinois.

“You can get only 50 to 55 per cent fuel from the distillation of petroleum crude oil. since this plastic is made from petroleum in the first place, we can recover almost 80 per cent fuel from it through distillation,” Sharma said.

Plastic bags make up a size able portion of the plastic debris in giant ocean garbage patches that are killing wildlife and littering beaches.

Plastic bag fake rolex s been detected as far north and south as the poles, researchers said.

“Over a period of time, this material starts breaking into tiny pieces, and is ingested along with plankton by aquatic animals,” Sharma said.

Fish, birds, ocean mammals and other creatures have been found with a lot of plastic particles in their guts.

Previou fake rolex s studies have used pyrolysis to convert plastic bags into crude oil.

Sharma’s team took the research further, however, by fractionating the crude oil into different petroleum products and testing the diesel fractions.

mixture of two distillate fractions, providing an equivalent of US diesel, met all of the specifications required of other diesel fuels in use today after addition of an antioxidant, Sharma said.

“This diesel mixture had an equivalent energy content, a higher cetane number (a measure of the combustion quality of diesel requiring compression ignition) and better lubricity than ultra low sulphur diesel,” he said.

The researchers were able to blend up to 30 per cent of their plastic derived diesel into regular diesel, found no compatibility problems with bio diesel,” Sharma said.

Plastic bags built to be yesterday’s news

However, a chemical added during manufacturing enables the plastic to be digested by microorganisms. The bags are supposed to disintegrate within a few months outdoors or three years in a landfill when exposed to oxygen and ultraviolet light, leaving behind little but water, carbon dioxide, organic metals, and salts.

The nontoxic, active ingredient speeding up the degradation includes a metal such as cobalt, according to Willow Ridge Plastics. It makes PDQ H, an additive that enables PolyGreen’ fake rolex s oxo biodegradable plastic to be eaten by microbes.

GP Plastics each year sells some $100 million in plastics that include sleeves that shield newspapers in soggy weather. Customers include The New York Times, USA Today, the Boston Globe and other newspapers published by Tribune, Gannett, McClatchy, and Newhouse News Service. newspapers use 7 billion plastic delivery bags, according to the Dallas based GP Plastics. When discarded, unfortunately, plastic breaks down into ever tinier molecules, polluting ecosystems and harming the health of animals and humans. fake rolex

“If you only saw some of the hate mail we get from people saying, ‘Your product is clogging the landfills and waterways,'” said Mike Skinner, GP Plastics’ chief financial officer. “Well, we’re working as fast as we can on this. city to ban plastic bags in supermarkets, GP Plastics protested. It and other plastics makers promoted bag recycling. However, only about 1 percent of plastic bags are recycled even in that city. The companies got to work building greener bags.

GP Plastics says its new newspaper sleeves cost only a fraction of a penny more than non biodegradable ones. In Bri fake rolex tain, Symphony Environmental Limited’s D2W plastic, like that of GP and Hilex, includes an additive to accelerate bi fake rolex odegradation.

Companies including BioBags have made biodegradable, compostable plant based plastic bags for garbage and yard waste for many years. However, plastic bags made from corn tend to break down too quickly to keep a newspaper dry, if flung into a puddle.

Yet some environmental groups suspect that the rise of bioplastics will only add to pollution and global warming. They frown upon growing genetically modified corn for plastics and worry that, as with harvesting plants for biofuels, food supplies will become scarcer as a result.

And some watchdogs contend that chemical additives designed to make petroleum based plastics degrade may prove in the long run to harm ecosystems. They are suspicious that the companies don’t disclose the exact ingredients in their additives.

“There is no such thing as biodegradable plastics,” said Stephanie Barger, executive director of the Earth Resource Foundation in Costa Mesa, Calif., which campaigns against plastic pollution.

“They’re still using petroleum, which is the No. 1 cause of global warming. What other kinds of chemicals are they putting in those plastic bags? If they’re saying salts and metals, well metals are damaging in high quantities.”
