SUVs vs. Trees: CO2 Emissions the Environment
One gallon of gasoline weighs about lbs. Of that, over 5 lbs. is carbon and the rest is hydrogen. The EPA says that burning one gallon of gasoline produces about pounds of CO2. The carbon atoms in the gasoline combine with about 14 lbs. of oxygen atoms from the atmosphere when the fuel burns to yield pounds of CO2.

New technique turns common plastic waste into fuel
New technique turns common plastic waste into fuel. Using byproducts of petrochemical production known as alkanes (saturated hydrocarbons where the hydrogen and carbon atoms are arranged in a branched formation in which all of the carbon to carbon connections are single bonds), the scientists were able to separate and reconstitute the polymer molecules into other useful compounds.
