New York also has a "waste oil" problem. And this "waste oil" is not the kind of mainland China and on the table of toxic food oil, but the real waste oil – dumped into the sewer fried vegetable oil. The oil blocked the sewer and needed to invest $ 6 billion to govern.

According to the business magazine "The Crain" (the Crain's) news, although the big city of waste oil has always been a problem, but New York City is particularly serious, especially in the Queens region. Perhaps because the residents of this area is from 120 countries in the world, the food of all ethnic groups are inseparable from edible oil.

Queens 7,500 miles of sewers are blocked every day, some 80% of the blockage is due to dumping of food oil caused by cooling and solidification. In the Queens area, the southern region of Jamaica is the most serious, and the 311 telephone station receives a complaint every three days.

New York City to solve this problem is a special company on the hotel to recover waste oil, used to produce biodiesel for municipal waste trucks and other motor vehicles. New York City has 24 such recycling plants.

Last October, Mayor Bai Sihao signed a bill requiring the city's hot oil use, the number of biodiesel from the current 2% to 20%. This allows the company to recycle the waste oil to see hope.

There is one reason why the trench is often clogged in the southern area of ??Queens, that is, the sewer is too narrow To this end, the Municipal Environmental Protection Bureau to prepare with $ 6 billion to overhaul. One can imagine that this will be a huge project.

Last year, New York City hired summer students to the Queen's District residents and restaurants knocked on the door, educating 50,000 families and 1,000 hotels how to deal with used food oil: that is, with non-recycled containers installed, and other garbage Thrown away; avoid pouring directly into the sewer. Because once the sewer is blocked, no one is better off.
