Turning Waste Into A "Treasure" &Nbsp; Leather Leftovers Actually Extract Edible Oil.

Using crude refining technology, from waste leather The waste oil is refined and made into poor quality oil, and the high concentration waste water produced in the refining process is directly stolen into the river. At present, an underground refinery in Tongxiang's Feng Ming Street, Xing Xing Village has been banned by relevant departments.

Reporters recently learned that the environmental protection department on the spot sampling of the water test results showed that COD (chemical oxygen demand, an important indicator of water pollution) content as high as 50 thousand mg per liter, more than 800 times the standard of sewage network.

In the village of Hefei City, Feng Ming Street in Tongxiang, an underground refinery is hidden with leather waste and leather waste to extract animal oil. After the rolling black smoke from the process of refining, the surrounding air is pollute unscrupulously, and the high concentration of wastewater is stealthily discharged into the river. Last week, the Tongxiang Environmental Protection Bureau received a report from the masses, and the joint industrial and commercial department banned the underground refinery.

The refinery is relatively hidden and very crude, with a roof on its roof and a black smoke rising from the yard. The air is filled with pungent smell, and more than 10 workers are working. In front of the open space, there were piles of waste plastic waste. Several workers were shovel the dry garbage into the car and then put it into the factory. There are black things stacked beside these plastic waste.

According to the introduction, the processing plant covers an area of about 3300 square meters, and there are 5 refineries. There are cooling pools beside the refinery boiler, and 15 storage tanks and dozens of bags of waste residue are placed on one side. It was found by law enforcement officers that the sewage pipes hidden in the firewood heap were found. It can be determined that the waste gas and wastewater from the processing plant are directly discharged into the air and outside the river without any treatment.

According to the workers at the scene, the process of "soil refining" used by the processing plant is very crude. They first put leather waste and leftovers in a closed boiler, and after cooking and melting, the impurities will be deposited on the bottom of the furnace, and the lighter oil will float on the top. The extracted oil is collected from the outlet and cooled by the cooling pool, and is collected from the oil outlet to the underground oil tank.

This oil must not be eaten.

The refinery has been in operation for half a month, and the raw materials used for refining are shipped from Haining. According to the workers here, after selling the oil to the market, they sell it to anyone. Law enforcement officers did not find any books at the scene, so the flow of these oil products has not yet been mastered.

Reporters interviewed learned that leather waste material contains a lot of impurities, if after a lot of high temperature refining, it will produce a carcinogen. In addition, it also contains aflatoxin, which can cause great harm to the liver and kidneys of the human body, so this product is absolutely not edible.

The underground refinery not only did not have any license, but also caused serious pollution to the surrounding environment by illegal production. The Tongxiang Environmental Protection Bureau has seized 50 tons of leather leftovers, scrap and 5 refineries. The scene staff said that he was a part-time worker, and the boss had disappeared. The officials of the village committee of Hexing village said they knew nothing about it.

Shen Yibin, deputy chief of the Tongxiang environmental monitoring group, said that this is a large underground refinery workshop which has been investigated by the Department in recent years. Shen Yibin said that because the underground oil refining did not take any environmental protection measures, the odor components emitted from various leather waste incineration are complex, and the most obvious is the production of harmful gases, which may make people sick. In addition, the high concentration wastewater from the refining process is directly discharged into the river, and the river section is the drinking water protection area of the environmental protection department, which will undoubtedly cause serious harm to the downstream drinking water sources.

At present, United Law enforcement The case has been handed over to the public security department for further investigation. Where the oil has gone, the relevant departments are investigating.
