Current Status of Oily Sludge in China
Oily sludge is classified as hazardous waste.
If not treated properly, it can cause negative impacts on human health and the ecological environment.
However, the current lack of macro and micro scientific understanding of the treatment of oily sludge hinders its sound management.
We are still far away from a sound management system of oily sludge.
Problems and Implications of Oily Sludge in China
The annual generation of oily sludge in China was between 4.45 and 6.22 Tg, and the average comprehensive utilization rate was approximately 36%.
The most widely used treatment method is thermochemical cleaning process. However, issues of secondary environmental pollution and excessive and inefficient use of resources are also becoming problems.
We are still far away from a sound management system despite new legislative revisions. Close supervision and technical processes should be further enhanced shortly.
