In the garbage heap “panning for gold” : kitchen waste in a short time became organic fertilizer

“Panning for gold” in the garbage

Put the leftovers, leftovers poured into, after decomposition treatment, became organic “soil”. A new equipment that uses biological processes to treat waste has been installed at a kitchen waste disposal site in Jimsar County, Xinjiang Province. It is understood that the kitchen waste treatment equipment, can let the kitchen waste in a short time through the biological flora decomposition and fermentation into organic fertilizer, kitchen waste to achieve on-site, harmless and resource treatment, to achieve no waste gas, waste water, waste three no emissions, will be kitchen waste waste into treasure.

This year is the first year of the 14th Five-Year Plan, and garbage classification will enter a new five years. Not long ago, the State Council issued the Guiding Opinions on Accelerating the Establishment and Improvement of a Green, Low-carbon and Circular Economic System, which calls for strengthening the recycling and utilization of renewable resources, promoting the integration of the two networks, and improving the green charging and pricing mechanism.

Industry insiders pointed out that under the promotion of national policies, China’s garbage sorting industry will step by step release the circular economy market, renewable resources industry, solid waste treatment industry, garbage sorting industry, sanitation facilities industry ushered in the dividend period.

Market Prospects Promising

In a community of Bajushan Road, Urumqi, a garbage sorting room is particularly conspicuous. The garbage sorting room is equipped with four different types of garbage releasing Windows. When residents approach, the Windows will open automatically to avoid direct contact with people.

Urumqi produces 4,500 tons of household garbage every day. As one of the 46 pilot cities of household garbage classification in China, the city plans to invest 706 million yuan to accelerate the classification of household garbage and strive to achieve the full coverage of household garbage classification in residential areas within two years. By the end of last year, Urumqi had basically established a household waste sorting and treatment system.

Hexingyuan residential area is the first residential area to carry out garbage classification pilot in Urumqi City. Xinjiang Siji Jinba Environmental Protection Technology Co., Ltd. entered the residential area to test the water garbage classification market in May last year with many years of experience in recycling waste materials. “Garbage is’ baby ‘, garbage classification market is a rich mine to be developed.” Ji Xuesi, head of the company, said. It is understood that the company regards waste classification and comprehensive resource recycling as the development direction of the enterprise, and invests 10 million yuan to build a factory to produce intelligent waste room.

Also optimistic about the prospect of garbage classification enterprises, and Urumqi Yinengda Machinery Manufacturing Co., Ltd. This to refit special vehicles and production of environmental protection equipment based enterprises, at the beginning of the national advocacy of garbage classification, quickly to the production of intelligent dustbin transfer, investment 200 million yuan to build two production bases, batch production has independent intellectual property rights of intelligent dustbin and buried type intelligent dustbin. Zhang Zhixiang, director of the company’s network operations, said that only the construction of garbage classification infrastructure has brought greater benefits to the company.

According to statistics, the national market scale of garbage sorting service in 2020 exceeded 61 billion yuan, and the market scale of restaurant waste treatment facilities investment during the “13th Five-Year” period reached 100 billion yuan. China has registered more than 600,000 waste-sorting companies over the past decade, according to data from SkyEye. Of these, 149,000 will be added in 2020, with an annual growth rate of 26%.

Look for gold spots

The kitchen waste biochemical treatment workshop of Jimsar County Environmental Hygiene Center in Xinjiang is the core “position” of swill treatment. A liquid crystal control panel and several control buttons are inlaid on the steel machine. The kitchen waste treatment equipment adopts advanced intelligent modular technology, set pretreatment, biological treatment and odor removal purification system in one, can up to 99% of the kitchen waste harmless treatment and resource recycling.

It is understood that there are many ways to deal with domestic waste, including landfill, composting, incineration, pyrolysis, biochemical, etc., and treatment methods are selected according to waste composition, economic development level, natural conditions and traditional habits. Although the way is different, but harmless, resources, reduction is the common direction of development.

With the advance of waste classification, the development of sanitation equipment industry is the most obvious. Fujian dragon horse sanitation equipment co., LTD has made sustainable development these days, according to the changing market demand, in particular, about the sanitation equipment “performance improvement, garbage classification, smart update” three directions research and development products, in addition to high altitude dust suppression, compression garbage truck, heavy junk car of new products, such as car in intelligent product research and development, completed the sweeper unmanned version 2.0 upgrade, successfully selected the first batch of national ministry of service-oriented manufacturing model enterprise.

“Transformation” of kitchen waste, “upgrading” of other wastes, and “purification” of harmful wastes…… Reporters learned that garbage disposal enterprises are constantly looking for “gold” point. At present, many places have set up waste incineration power plants. Incineration of 1 ton of garbage can generate 280 kilowatt-hours of electricity. The remaining slag after incineration can be pretreated to separate metals, and can be manufactured into cement standard bricks and cement nine-hole bricks through processing. One ton of slag can produce 315 cement standard bricks.

Nowadays, more and more investors and entrepreneurs enter the garbage classification industry and explore how to integrate all aspects of the garbage classification industry to form a perfect market-oriented operation system belonging to the garbage classification industry.

Innovation drives development

According to Zhang Wei, chairman of Urumqi Ynengda Machinery Manufacturing Co., Ltd., the company has developed an intelligent garbage sorting and collection device, which is equipped with a smart garbage sorting big data cloud platform. The device can be tied to residents with real name system, and can be exchanged for cash or prizes if correctly placed. At present, the equipment has been in the entire area of Xinjiang put nearly 1000.

It is understood that the emerging things, industries, technologies and service models brought about by garbage classification affect the direction of the next garbage classification. Industry insiders point out that innovation and development should be made in the course of development, and innovative products under the garbage classification policy are of more analytical value at present.

At present, the work of garbage sorting mostly adopts the form of government subsidies to support the development of industries and enterprises. The personage inside course of study points out, as the industry chain system barriers gradually get through, and the basic mature and stable market, the government will certainly stop “blood transfusion”, so the garbage classification industry and enterprise, only promote renewable resources of scrap, to maximize the economic benefits of the renewable resources, make its have the ability to self “blood” and to ensure the healthy and orderly development of industries and enterprises.

Liu Kehua, member of the Chinese People’s Political Consultative Conference (CPPCC) of Xinjiang Uygur Autonomous Region, suggested that an information platform for recycling renewable resources should be established to provide information on recycling types, transaction prices and recycling methods so that renewable resource recycling enterprises can conduct transactions and realize the recycling of waste resources.

At present, many garbage sorting enterprises begin to focus on the research and development of basic equipment, relying on the Internet, cloud computing, big data, Internet of Things and other technologies, to realize the synchronous operation of hardware equipment and software system. Through the self-developed APP or mobile background, the garbage classification behavior of residents can be detected, which is convenient to make timely and accurate data statistics, and realize the intelligent and standardized development of garbage classification.
