Competition with biodiesel”
Thread Content
Food waste oil is one of the raw materials for biodiesel. Due to various issues related to its supply, etc., its use in biodiesel is limited. But there are new ways to deal with the oil from food waste in sewers. The city’s sewers have become a source of wealth for some people. Every day, they extract large quantities of dull, turbid, slightly redish paste from there; after just one night of filtering, heating, settling, and separation, this foul-smelling waste is transformed into clear \"edible oil\", which is then sold at low prices and returns to people’s tables. He Dongping, a professor at the School of Food Science and Engineering at Wuhan University of Technology, told China Youth Daily that currently, 2 to 3 million tons of gutter oil make its way back onto dining tables in China each year. The total annual consumption of animal and vegetable oils by the Chinese is approximately 22.5 million tons. In other words, proportionally speaking, out of 10 meals you eat, there’s a chance that 1 of them may contain gutter oil. Research in the medical field shows that long-term consumption of gutter oil can cause significant harm to the human body, such as developmental disorders and an increased susceptibility to enteritis, as well as conditions like enlargement of the liver, heart, and kidneys and fatty liver disease. Aflatoxin, one of the main harmful substances in gutter oil, is a potent carcinogen whose toxicity is 100 times that of arsenic. ! A gentleman values wealth, but acquires it in an honest manner.

Recently, I saw media reports from Shenzhen’s bus services highlighting the city’s vigorous efforts to regulate the edible oil market.
If it were more profitable to use used oil to produce biodiesel, it wouldn’t end up back on our tables. So, biodiesel, grow up quickly. ~
It is the responsibility of local authorities to take action: to establish designated collection systems, carry out environmentally friendly processing, keep records of the collection process, and send the materials to specialized facilities for biodiesel production, thereby creating a closed-loop system that serves the well-being of the people.
I don’t know how much used cooking oil is back at the dining tables now. The price of used cooking oil for biodiesel may have reached 4,200 yuan per ton.
Ah, it’s really time to take action; otherwise, once problems arise, it will be too late to regret it. Additionally, biodiesel needs to be developed further – it would be great if waste oil could be used to produce biodiesel, and if this practice could be widely promoted.
