How to deal with "gutter oil" in Hang Cheng? The municipal environmental group gives a new answer.
Waste cooking oil generally refers to all kinds of inferior oils existing in life, such as recycled cooking oil and repeatedly used fried oil. The biggest source of waste oil is the grease trap in the sewer of large hotels in the city. Long-term consumption may cause cancer, which is extremely harmful to the human body. How to further optimize the standardized collection and resource utilization of waste oil, and support the "collection and disposal" of waste oil market in Hangzhou? In 2022, exploring the standardized management mode of "waste oil" collection, transportation and disposal was included in one of the ten new things that benefited people’s livelihood in the Municipal Environment Group. In a blink of an eye, a year has passed. What progress or effect has this matter made?
Annual collection and transportation of "gutter oil" is 529.5 tons.
Municipal Environment Group explores standardized management mode of collection, transportation and disposal.
A few days ago, the Municipal Environment Group published a "report card". By the end of 2022, a total of 1,048 locations have been touched, 96 collection and transportation agreements have been signed, 605 vehicles with 529.5 tons of waste oil have been collected and transported, and 49 oil extraction operations have been carried out, with a total oil extraction rate of 31.94%. At present, all three existing waste oil collection and transportation vehicles of the Group have achieved full production operations.
"Perishable garbage such as gutter oil is both resource and pollution." Meng Bo, deputy manager of the Resource Division of the Municipal Environment Group, said, "The oil content is high, so the recycling value is high. However, if it is not discharged according to the standard, it will cause pollution to the environment, or it will be recycled and processed by unscrupulous merchants and then flow into the market, which will cause harm to society. "
According to reports, since 2019, the Resource Utilization Division of the Municipal Environment Group has focused on the preliminary investigation of the collection, transportation and disposal of trench oil in Hangzhou. In October, 2020, the Municipal Environmental Group was included in the list of qualified waste oil collection and transportation units in Hangzhou. Then, it is to carry out the work of arranging the waste oil production units in Hangzhou. "Mopai work is mainly divided into two steps, one is for schools, institutions and complexes with perfect kitchen management, and the other is to start from shops along the street." Meng Bo said.
With the expansion of standardized management mode, by the end of 2022, the amount of waste oil collected will increase from the initial 22 tons per month to about 185 tons per month now.
It is worth mentioning that, for the daily waste oil collection and operation industry, the collection and transportation line of the Municipal Environment Group realizes the special transportation by special personnel and the whole process supervision.
"Up to now, the Resource Division has recruited 5 full-time collection and transportation personnel, and each collection and transportation vehicle of waste oil is equipped with GPS on-board monitoring, etc. to monitor and standardize operations in real time. Not only that, at present, real-time data collection and real-time monitoring of the flow direction of collection, transportation and disposal are realized from the source to the end. " Meng Bo told reporters.
According to reports, after the waste cooking oil is transported to the waste oil processing line of the Municipal Environment Group, it will be processed by a series of processes such as solid-liquid separation, oil purification, water removal and impurity removal to form the final product "crude oil", which can be finally produced into biodiesel, biogas, chemical oil and other products.
Strive to complete the collection and use of "waste oil" in Hang Cheng as soon as possible.
Call on more enterprises and units to do standardized disposal.
"The waste oil treatment and processing line of Tianziling Kitchen Project can handle 45 tons of waste oil every day. However, at present, the waste oil collected and transported by the contracted units is only about 7 tons, and there is still a big gap between the disposal volume and the actual collection volume." Meng Bo said frankly.
To this end, the Resource Division will continue to carry out in-depth research and expansion of perishable garbage sections. Taking "strengthening the main business, doing excellent sideline business and expanding new business" as the criterion, we will do a good job in supporting construction, optimize sales strategy, deepen employment mode and improve vehicle management, and strive to achieve full-load disposal as soon as possible.
However, with the deepening of the investigation, we will find that the "waste oil" market and the "portals" for collection, transportation and disposal are also various. Without a sensitive sense of smell, it is impossible to find a suitable entry point.
"For example, some small catering shops along the street often gather together and share a grease trap, which makes it more difficult to expand, especially some shops lack legal awareness. In the process of communication, we will also do a good job in publicizing laws and regulations, and at the same time explain the positive value of waste oil recycling to them." Meng Bo said.
In order to ensure the "safety on the tip of the tongue" and eliminate the hidden dangers of food safety, the Municipal Environment Group also called on everyone to do a good job of "CD-ROM action" in their daily lives. In addition, they should bravely say "no" to the illegal acts of waste oil discharge, collection, transportation and disposal. At the same time, it is also hoped that the units or enterprises that produce waste oil can handle it safely and standardly.
