With summer just around the corner, it won't be long before we can once again
quench our thirst with a juicy slice of watermelon.
But of the 400 billion pounds of watermelons grown each year, 800 million pounds
are rejected because they are either blemished or deformed.
Now there is a use for all those rotting watermelons.
Science Daily reports that a 20 pound watermelon can yield a 1.5 pounds of sugar, enough to produce 7/10 of a pound of ethanol. And chemist Wayne Fish has also shown that ethanol can be extracted from the waste stream of watermelons used for nutraceuticals (like lycopene a powerful anti-oxident).
This is good news for the watermelon industry. Farmers gain an extra cash crop and the nutraceutical industry which extracts watermelon compounds, will have reduced waste water treatment expenses.
