Future
A new process to break down polyethylene, a common plastic product found in many consumer containers, is used to make wax with the correct molecular properties for conversion into a lubricant, bypassing the expensive Fischer-Tropsch process. The plastic is melted and then pumped into a furnace. The heat of the furnace breaks down the molecular chains of polyethylene into wax. Finally, the wax is subjected to a catalytic process that alters the wax's molecular structure, leaving a clear oil. (Miller, et al., 2005)
Biodegradable Motor Oils based on esters or hydrocarbon-ester blends appeared in the 1990s followed by formulations beginning in 2000 which respond to the bio-no-tox-criteria of the European preparations directive (EC/1999/45). This means, that they not only are biodegradable according to OECD 301x test methods, but also the aquatic toxicities (fish, algae, daphnie) are each above 100 mg/L.
Another class of base oils suited for engine oil are the polyalkylene glycols. They offer zero-ash, bio-no-tox properties and lean burn characteristics.

Famous quotes containing the word future:
“the future is simply nothing at all. Nothing has happened to the present by becoming past except that fresh slices of existence have been added to the total history of the world. The past is thus as real as the present.”
—Charlie Dunbar Broad (1887–1971)
“Our system of government, in spite of Vietnam, Cambodia, CIA, Watergate, is still the best system of government on earth. And the greatest resource of all are the 215 million Americans who still have within us the strength, the character, the intelligence, the experience, the patriotism, the idealism, the compassion, the sense of brotherhood on which we can rely in the future to restore the greatness to our country.”
—Jimmy Carter (James Earl Carter, Jr.)
“The future is built on brains, not prom court, as most people can tell you after attending their high school reunion. But you’d never know it by talking to kids or listening to the messages they get from the culture and even from their schools.”
—Anna Quindlen (b. 1953)
