Wool scraps "gold rush"

Business News Agency December 8th, the reporter went into the Huzhou State Entry-Exit Inspection and Quarantine Bureau in Zhejiang Province, South Branch Office of the plant quarantine, see the staff is sitting in front of the table, in a pile of garbage things carefully looking for something . Seeing the reporter's doubtful eyes, the person in charge of the lab introduced: “This is the leftover of wool. We are separating weed seeds from it. This work is boring and sometimes it takes only one day to sit.”

“In the first three quarters of this year, the Huzhou Port received a total of 175 weed seeds from imported wool.” This reporter learned that the wool textile industry is one of the characteristics of Huzhou City, and the demand for the original wool is relatively large. More than 99% comes from Australia, and the import type is unshredded sheared wool. Since the wool-producing sheep are grazing on the grasslands, a large number of weed seeds will be mixed into the wool, increasing the risk of alien harmful weeds entering the territory. Since this year, the city’s inspection and quarantine departments have intercepted a large number of weed seeds from imported wool, among which quarantine pests such as French wild oats, blue clams, and triangular bristles have all been intercepted for the first time in Zhejiang. "If we adopt simple measures of destruction or return after weeds are intercepted in imported wool, the original wool processing company will cease to exist." The person in charge of the laboratory is the largest wool import processing enterprise in Huzhou City - Zhejiang Zhongxin Wool Textile Co., Ltd., for example, calculated an account for the reporter. "China-New Zealand" imported nearly 6,000 tons of wool every year, the value of nearly 30 million US dollars, an average of 100 kg of miscellaneous materials and five or six tons of wool processing waste every day. If a simple method of destruction or return is adopted after the interception of harmful weeds in imported wool, then it is not only that China Xinmao Textile Co., Ltd. cannot carry out production, and Other original wool processing companies will no longer exist because these enterprises 80% of the original wool is imported.

In the face of the large import volume of enterprises, it is urgent to find a quarantine treatment that can completely eliminate weed seeds and maintain the normal import of wool. It is the simplest and straightforward way to incinerate waste mixed with grass and raw wool. However, due to the scarcity of grass and waste left on the production line, especially the waste containing heavy water, it is difficult to burn. Even if it can burn, it will produce a lot of smoke containing toxic and harmful substances and pollute the environment. If you purchase a large-scale high-temperature incinerator, although you can reduce the environmental pollution, companies need to invest a certain cost. The way of thinking decided to go out and the inspection and quarantine department collected information and consulted experts in a timely manner and put forward the idea of ​​fermentation processing. They have conducted site surveys on many occasions and have actively guided enterprises to build fermentation tanks that ferment wool leftovers.

While the haystacks burned burningly, bubbles froze in the fermentation tank. The person in charge of China-New Zealand said that these scraps contain sheep manure, sludge, grease, weed seeds and other substances. The traditional harmless treatment method has high cost and environmental pressure, and now it is used for cement. The fermentation tanks are inexpensive and can effectively eliminate pests that are not included. At the same time, organic matter in the leftovers can be recycled and reused to reduce the eutrophication of the sewage, so that the sewage that was once rejected by the original sewage treatment plant can finally enter the sewage treatment plant for treatment, and real waste turning becomes a treasure.
