Back in 2011, Time Magazine reported that Chinese officials had commenced a six-month investigation into gutter oil that resulted in the arrest of 32 suspects and the seizure of 100 tons of illegal oil that they believed were being processed for resale.
One year later, another crackdown occurred that resulted in 100 arrests and the closing of 13 processing plants across four provinces.
Despite these sporadic crackdowns, however, all evidence suggests that the gutter oil industry continues to thrive in the biggest Chinese cities due to its immense profit-making capacities.
