In the past three years, the news replayed more than 80 tons of kitchen waste, such as cooking oil, which was the main source of “oil waste”. At 8 o'clock in the evening on September 21st, 2011, under the leadership of the Municipal Food Safety Office, Changsha dispatched more than 100 police officers and related law enforcement personnel to carry out a carpet-like “oil waste” at the junction of the suburbs of Mapo Ridge in Furong District. Special rectification actions. The joint inspection team arrived in Zhanggongling Village, Dongan Township, Furong District, and inspected a waste oil recycling company called Hunan Provincial Recycling Resources Corporation. Law enforcement officers first checked the company’s ledger and sales contracts, and took them to the police station in Mapo Ling for further inspection and verification.

Subsequently, the inspection team inspected another five processing sites for waste oil and swill oil. In a squatter settlement in Xilong Village, the inspection team discovered an unfamiliar ditch oil processing black den, immediately sealed all production tools, raw materials, and finished products on site, and banned the black dens on the spot.

It is understood that since 2008, the city has inspected 4,692 households engaged in edible oil business operations, ordered 220 households to be rectified, and banned 223 households without licenses for edible oil; investigated and dealt with 615 vehicles that illegally carried “sewage oil” and “drainage oil”.捣 Destroyed more than 100 illegal dens of production and seized and sealed more than 80 tons of “sloppy oil” and “sewerage oil”.

Reporter unannounced visits to some restaurants to dump rubbish on the road, and some members of the public have reported that a small number of street restaurants or restaurants are always dumping oil effluent or leftovers on the road. Over time, the road became a public garbage dump and became an "oil road." The reporter saw in the vicinity of Wangchengpo that the phenomenon of rubbish dumping on the street was serious.

There are four or five small streets and alleys in the Wangchengpo Trade City area. There are a lot of street restaurants. Every few meters on a small street, there are rubbish, wine bottles and coal cinder, and the sewage flows. In front of some restaurants, garbage has not been packed, leftovers, plastic bags, disposable chopsticks, lunch boxes, etc., and they all fall on the side of the road. There were also some shops that poured some unpleasant drowning on the side of the road. The backstreet of these stores became a place to wash vegetables and choose dishes. Washing pot water, coal ash, and drowning were everywhere, and the aisles became oil and roads. They could not leave.

A sanitation worker at Wangchengpo Sanitation Institute told the reporter that the cleaning task in this area is particularly heavy. Only the commercial and commercial areas will carry away at least 5 to 6 vehicles per day (especially for cleaning cars). In particular, there will be more rubbish in the evening at the hotel. They will go out early to clean up at 4 o'clock in the morning.

During the interview, some restaurant owners said that the roadside trash can not accommodate a large amount of food waste. They have no place to throw rubbish, so it is very difficult.

Changsha Action Stepped up Construction of Kitchen, Kitchen, and Garbage Disposal Center On June 1, 2011, the “Changsha City Restaurant Kitchen Waste Management Regulations” was implemented. The management measures made “The restaurant-kitchen-garbage-generating unit should establish a ledger to record kitchen garbage. The quantity and direction of production, and the activities of restaurant-kitchen-garbage collection, transportation, and disposal should obtain the service permit for restaurant-kitchen-garbage collection, transportation, and disposal activities, etc., and pointed out a clear direction on how to deal with restaurant-kitchen-garbage, but it is difficult to implement. .

During the interview, Zeng Qing'an, deputy director of the Changsha Municipal Bureau of the Communist Party of China, said that in order to effectively control "roadside oil" and "sewage oil" and effectively control roadside rubbish, it must first be dealt with from the terminal and needs supporting policies to follow up. It should be clear that there is qualified recycling processing. Units and designated garbage disposal centers. At present, the Changsha Restaurant Kitchen Waste Disposal Center has not yet been completed, which is also an important reason why the “Changsha City Kitchen Waste Management Measures” cannot be truly implemented.

Zeng Qing'an introduced that from 2010 onwards, the country will step up the implementation of restaurant-kitchen-garbage disposal and put it on trial in 33 cities nationwide. Although Changsha is not a pilot city, Changsha Municipal Party Committee and the municipal government attach great importance to it, and has included restaurant and kitchen waste disposal as a key construction project in 2011.

According to reports, at present, Changsha restaurant kitchen waste processing center has completed the bidding, Hunan Renhe Environmental Protection Technology Co., Ltd. and Zoomlion joint bid, they will be responsible for food waste collection and processing and equipment supply tasks. In the next step, there is still a lot of work to be done, such as the establishment of a city-level leading group to hold a coordination meeting to thoroughly analyze the situation of food waste in the city, and to seize the time for plant construction, vehicle purchase, equipment installation, and base construction. The center strives to be completed and put into use in June next year. The daily throughput of the three production lines can reach 300 tons to 500 tons per day.

How to deal with food waste from kitchen food waste After the completion of the biodiesel kitchen garbage disposal center, how does Changsha's food waste be treated? Zeng Qing'an introduced that all meal-kitchen wastes will take the form of anaerobic fermentation to separate oil and water; the separated oil will be used to make biodiesel, and the separated sewage will be discharged through sewage treatment; the residue will have four treatment channels after being sterilized by high temperature. In addition to making feed, fertilizer and soil, biogas can also be generated through anaerobic fermentation to generate electricity, and the fourth is the most environmentally friendly. Changsha will follow the principle of environmental protection.

Zeng Qing'an stated that after all operations are in place, all catering outlets in Changsha must sign a garbage collection and transportation contract to ensure that all restaurant-kitchen garbage does not flow out. Acquisition companies will also unify vehicles and signs, and those who recycle food waste must also hold certificates. At the same time, **, public security, traffic police and other departments will increase the linkage law enforcement, if found problems will be handled illegally, give fines, suspend business rectification and other corresponding penalties. At present, the ** department is also stepping up drafting detailed implementation rules and is expected to be introduced in March 2012.
