The concept of "sewer oil" first appeared in China in 1998. China's outspoken media, the Southern Metropolis Daily, launched a series of investigative reports on "underground mills refining peanut oil from waste grease" during "Consumer Day" on March 15th, 1998. Since then, the term "sewer oil" has taken firm root in the daily lives of Chinese people. Have questions? Do you have something to share with us about China? We want to hear from you!
