Waste oil, whether it is mineral oil or animal and vegetable oil, can be used as a fuel or reused raw material for engines, burners or boilers as long as it is processed and refined. It is a typical "green energy". In addition to promoting the economy, the development of green energy can In addition to sustainable development, energy conservation, carbon reduction and environmental pressure reduction, it also makes important contributions to the control of urban air pollution and the reuse of waste cooking oil.

However, in recent days, waste cooking oil has flowed into the hands of unscrupulous businesses, which are converted into cooking oil and sold for huge profits. Waste lubricating oil or waste solvents are often exposed in the TV media, polluting hillsides, rivers, soil and even oceans due to illegal dumping. The Environmental Protection Agency and various county and city environmental protection bureaus are unable to grasp the source and destination of waste cooking oil (such as waste cooking oil, waste lubricating oil, waste solvents, etc.), and they cannot effectively prevent waste cooking oil from flowing into underground manufacturing plants. Or illegal dumping; coupled with widespread public opinion and news media reports, government agencies and private businesses urgently need an efficient and simple management system and method to manage the source and destination of waste cooking oil, and ultimately achieve traceability and elimination of production sources. Double standards such as resumes are a blessing to all people.
