Passage 1: Biofuels: The Ultimate in Recycling
by Jeanne Miller
Will there come a day when you can use the oil that your egg roll was fried
in to power your car? How about the potato peels left over from making instant
potatoes?...
In fact, that day already has come. Facilities that convert organic matter,
called bromass, into clean-burning fuels are more and more often choosing to use
waste products from other processes to produce biofuels.
Ethanol and biodiesel are the most common biofuels, and they provide
environmentally friendly alternatives to gasoline and to petroleum diesel fuel.
Best of all, using surplus materials to produce biofuels solves another big
problem: what to do with all the waste we generate.
Ethanol, an alcohol, is produced after yeast or microbes break down a plant's
sugars and starches. Combined with gasoline, it adds oxygen to the car engine's
combustion process, allowing the fuel to bum more cleanly. A company in Idaho
makes ethanol using potato waste from a nearby potato processing plant. A cheese
factory in California makes it from unused whey. Almost anything that ever grew
can be processed to make ethanol.
Biodiesel, made from chemically altered plant oil or animal fat, is an
alternative to petroleum diesel and will work in any diesel engine. When used as a
substitute for petroleum, it reduces total air pollution by more than 50 percent and
cancer-causing substances in the exhaust by 94 percent. About half of the
biodiesel that's produced in this country is made from used vegetable oil.
Most intriguing of all is the oil produced by a machine developed by
Changing World Technologies that uses a thermal depolymerization process
(TDP) to take materials apart at the molecular level. The machine was designed to
turn almost any waste product into high-quality oil, pure minerals, and clean
water. It applies heat and pressure, the same forces nature employed to turn
ancient vegetation into fossil fuels.
However, what took nature thousands or millions of years takes this machine
a couple of hours. The company's Philadelphia plant has been operating for four
years, taking in waste of all kinds: turkey innards, tires, city garbage, muck
dredged up from the harbor, medical wastes. What comes out is light oil, gas, and
minerals, all pure and harmless. A larger TDP plant in Carthage, MI, expects to
turn 200 tons of daily turkey-processing waste from the Butterball factory just
down the road into 10 tons of gas: 21.000 gallons of water. 11 tons of minerals:
and 600 barrels of petroleum and other oil. More plants are planned.
Although producing biofuels generally costs more than pumping petroleum
out of the Earth, the added cost is offset by many benefits. These alternative fuels
provide energy without harming our environment and depleting our country's
resources. They offer the added bonus of solving our solid waste problems. It's a
good deal for Planet Earth!
