Since 2011, the Chinese government has significantly cracked down on the reuse of gutter oil for human consumption,[3] with the Chinese government also implementing clearer regulations for dealing with waste oil.[4] Selling gutter oil in China can result in lengthy prison sentences or the death sentence with reprieve. For example, in 2014, businessman Zhu Chuanfeng was sentenced to the latter for selling gutter oil.[5] That same year, a major gutter oil scandal was uncovered in Taiwan.[6] In 2015, Yeh Wen-hsiang, who was the chairman of a Taiwanese food company, was sentenced to 22 years imprisonment and fined the equivalent of $1.6 million[ambiguous] for selling 243 tonnes of gutter oil.[7][8]

Interesting. Meanwhile, wonder how the US is doing?
