Glycerin byproduct from biofuel refining now being reused

Prodigious amounts of glycerin are produced as a byproduct of biofuel, and sometimes was being landfilled. However, scientists now have devised a multitude of ways it can be used and reprocessed.

Waste glycerin can be made into a profit center, yielding high-value chemicals (alcohols and acids) that can be used to make fabrics, insulation, and food products, as well as additional fuels. Other researchers have been developing ways to convert glycerin into ethanol, methane, hydrogen gas, and even a non-toxic antifreeze.

Thus, they are turning waste into useful goods and increased profits. More and more, businesses are discovering what they thought was garbage can be used for good purpose.
