Waste Cooking Oil
Proper disposal of used cooking oil is an important waste-management concern. Oil is lighter than water and tends to spread into thin and broad membranes which hinder the oxygenation of water. Because of this, a single litre of oil can contaminate as much as 1 million litres of water. Also, oil can congeal on pipes provoking blockages.
Because of this, cooking oil should never be dumped in the kitchen sink or in the toilet bowl. The proper way to dispose of oil is to put it in a sealed non-recyclable container and discard it with regular garbage. Placing the container of oil in the refrigerator to harden also makes disposal easier and less messy.
Cooking oil can be recycled. It can be used to produce soap and biodiesel.

Famous quotes containing the words waste, cooking and/or oil:
“The fetish of the great university, of expensive colleges for young women, is too often simply a fetish. It is not based on a genuine desire for learning. Education today need not be sought at any great distance. It is largely compounded of two things, of a certain snobbishness on the part of parents, and of escape from home on the part of youth. And to those who must earn quickly it is often sheer waste of time. Very few colleges prepare their students for any special work.”
—Mary Roberts Rinehart (1876–1958)
“For the writer, there is nothing quite like having someone say that he or she understands, that you have reached them and affected them with what you have written. It is the feeling early humans must have experienced when the firelight first overcame the darkness of the cave. It is the communal cooking pot, the Street, all over again. It is our need to know we are not alone.”
—Virginia Hamilton (b. 1936)
“To make a good salad is to be a brilliant diplomatist—the problem is entirely the same in both cases. To know exactly how much oil one must put with one’s vinegar.”
—Oscar Wilde (1854–1900)
