Straining the oil pool of the back of a restaurant. Straining the oil pool of a underground of commercial mansion. The oil of underground drainage, one stimulates the public's sensitive and neural vocabulary about food security again and again. Really walk close to it, just know these seem black, greasy and oily, the rubbish oil which smell sour and rotten and incomparable, also can change body into the fuel of car, industrial chemicals, utilize producing the biological diesel oil in short supply of market, white and bright plastic steel doors and windows again through retrieving, tantamount to turning the foul and rotten into the rare and ethereal. It is estimated Beijing produce 90,000 the intersection of underground drainage and oil every year, person who collect 60,000- 7 ten thousand effectively, and retrieve at present and utilize ability to be fewer than ten thousand tons. Is its reason whether oil of underground drainage is difficult or difficult to transform to collect? How could should collect and accept to the limit, turn waste into wealth? The reporter has investigated further. 1 turns waste into wealth - - Enterprises use the form of the contract, help the individual who washes the oil of underground drainage to sign the agreement with the restaurant, concentrate on storing washing the oil had, and then all purchase to and smelt melting in the factory, make biological diesel oil At 8 o'clock on the the morning of July 23, Lao Zhang married couple drive a medium-sized minibus, come to three storeys in the mansion underground of global trade of N.3rd Ring Road. Open the door, full inside hold 30 green plastic barrels, and 3 big strainers which wash the oil. On the car, on the barrel, dip in yellowish-brown greasy dirt at the strainers, send out the sour stink. The property personnel of the mansion open the door of a work cubicle, inside is that the stainless steel two meters square strains the oil pool, the white ceramic tile is stuck on the wall, seem very clean. But as reporter follows old Zhang station and reaches to strain the oil pool, open the cover, it was the muddy thing of greyish black which mixes various rubbish that hove in sight, whether it is a solid or liquid to outwardly nearly tell, is distributing the rotten smell of acid. Lao Zhang says to reporters while dragging for a layer of viscous things above with the big strainer: "This is oil of underground drainage, ran to here from the sewer of each restaurant in the mansion. " As expected, drag for and float the black ashy rubbish greasy dirt above, see following sewage. Build thoroughbred horse's introduction according to the horse of management office of solid offal of committee of municipal appearance of the city of Beijing, it is a department in environment protecting mode to the requirement in the leading examination and approval of food and beverage shop to build and strain the oil pool. The waste water of kitchen cabinet must be through filtering the oil pool, the profit proportion of use is separated badly tentatively, could arrange into the urban sewage line, otherwise very apt to stop up the pipeline. See real underground drainage oil for the first time, its dirty intensity is still the expectation exceeding the reporter greatly, "why does such a dirty thing want it? " "This dirty things are very costly! Pay the money to wash for the hotel, can sell five or six thousand yuan each ton after washing back and cooking, I want a lot of if there is a lot of! " The rubbish greasy dirt that these other people looked dirty and incomparable was but fought for by many people in Lao Zhang's eyes " The treasure " . He tell reporter whether Beijing have 3000 people it does this to be all right nearly, nearly half Taizhou of fellow villager Jiangsu people of him. It is them initially " Develop " This pieces of trade,last Anhui, Sichuan, Northeastener entry, the relative took the relative, the fellow-villager led the fellow-villager to start working. They call the mixtures of this kind of underground drainage oil, rubbish, sewage " Mao are oily " ,After cooking and precipitating, strain the waste residue, can produce 30%- 50% of the " precise oil " . These " precise oil " It is sold for 5000- 6000 yuan per ton on the market, very in great demand. About one hour, Lao Zhang married couple strain three of three mansions in the oil pool to finish dragging for, have filled with 10 barrels, use the mop to sweep the ones that strain the oil pool room clean. Then drive to go in the next point: Ten thousand willow East Road meat-roasting as if. This one restaurant of roadside, to strain the oil pool at ground outside the room of the back of the restaurant it. The reporter notices, two iron plates such as two iron gates are welded on the ground, has also locked with the iron chain. Lao Zhang opens the lock, raise the iron plate, just show the well lid of our common entering the water. "Not locking, the oil will be stolen. " Lao Zhang says, he comes to wash it once every week, can fill with two barrels each time, but only install half a barrel this time. "It may have rained heavily a few days ago, straining the oil pool was washed. " As if, Lao Zhang goes to wash 6 restaurants and underground of the mansion building to strain the oil pool by car to leave meat-roasting. At two o'clock in the afternoon, the oil of underground drainage was filled with 30 plastic barrels, Lao Zhang comes back with fruitful result. He leave urban area by car, drive towards residence is " the maos of oil " too Store the ground temporarily - -Xindian of Fengtai head of district. Drive 75 kilometers from N.3rd Ring Road, west Sixth Ring Road from the mound stone road, large gray factory's east street product is southwards, the reporter follows Lao Zhang to come to a secluded courtyard outside the hard north village of village village of Xindian of head of district of Fengtai of Beijing. The courtyard sees a row is about one meter high, two meters 15 iron cupboards that number long and neat to enter. Lao Zhang says while pouring the underground drainage oil in the plastic barrel into the iron cupboard, cupboard these whether the intersection of they and oneself weld personally, each one, number, each hold, each cupboard can hold 5 tons, about 80 barrels. It is Lao for Zhou houses of person in charge of courtyard in this in workers ashy print striking loading onto " Solicit sum in Beijing of China " . He washes the oil of underground drainage bringing to 15 relatives or fellow-villagers such as Lao Zhang than old Zhang's earlier entry. "I am ' regular army ' that the government approved now, the company is responsible for signing for the oil agreement with the hotel, responsible for, arrive, smelt, take processing factory, produce the biological diesel oil ' maos of oil ' still. " Lao Zhou's words are candid. He say have much to wash the intersection of underground drainage and people of oil around the the intersection of Beijing and Sixth Ring Road, they wash " the maos of oil " that come Cook, precipitate, filter, turn in the open into " precise oil " ,Sell and specially call to the person who harvested the oil at high price. These charge the intersection of oil and people, known as" Smelt black oil " (used after an attribute). " precise oil " " smelted and deceive the oil " After putting away,no know end. "The government is in charge of tight now, they are all stealing oil refining, many people plan to join the regular company like us, it is steady and sure to do like this. " Lao Zhou says. Real China, Beijing of China, new the intersection of energy and Science Technologies Co., Ltd. to collect, transport, process, refine the biological diesel oil to integrative enterprises in municipal the intersection of appearance of the city and the intersection of collection and the intersection of kitchen cabinet and waste oil that committee is put on record, it is and its wholly-owned subsidiary to solicit in Beijing of China, is responsible for collecting the waste oil specially. Set out from hard north village of village village, the reporter follows and draws " mao are oily " Tank wagon,come Fangshan coloured glaze river three street. Here hits a discarded chemical plant which will take up an area of 1.667 hectares that the real China Company of Beijing will purchase in 2008. This company does things simply and thriftily, investing 7 million yuan is repaired and transform, refine the biological diesel oil with the oil of underground drainage with own technology, transform 5000 tons of ability every year. XiangYu Zhang, person in charge of factory, tell reporter, " the maos of oil " Heat and precipitate turning into " The precise oil " And then, add to reflecting it in the kettle, wash the preconditioning with 10% brine, precipitate, discharge the moisture, then add methanol and sulfuric acid and carry on the treatment of esterification, this is transformed into the committed step of the biological diesel oil of oil of underground drainage. After the treatment of esterification, the acid in the oil frustrates fatty acid to turn into flammable first ester of fatty acid, can no longer eat, just stop the possibility of the oil reflux dining table of the underground drainage completely. "Such esterification course needs to carry on for 3 times, amounts to about 9 hours. After the high temperature is distilled and dehydrated, turn into and can be listed the biological diesel oil sold. " Conclude the business in 2 underground - -90% of the " precise oil " With high price of five or six thousand yuan per ton, through " smelt black oil " People have hands, flow into the other places. Among them is infiltrated partly " There is not three " However, unfortunately, such a processing factory that can turn waste into wealth in the dining table of the reflux in the edible oil, but is often in half a state of stopping production. "Raw materials waste oil can not be collected! " Zhang XiangYu sighs with deep feeling, 5000 tons can produce and not big, but just produce more than 1000 tons at most in one year. "The pricing right of underground drainage oil of now is in the hand who smelts black oil. " Beijing of middle solicited and served general manager of Co., Ltd. Li Yong with environmental protection to calculate an account for the reporter, the current price on market of the diesel oil is in 7000 yuan / about ton, buy " precise oil " in the individual hand of the waste oil from accepting at present It want 5000 yuans /ton the above,in addition, the middle smelt by cost about 1400 yuan that be taken,is there gross profit of less than 1000 yuan each ton only. And " smelt black oil " Person " The precise oil " Refine additive edible oil, each cost so long as 700 more than, mix, eat with can sell for 15000 / high price of ton in the oil. "The space that the person that ' smelt black oil ' can gain is big, they raise the price constantly in harvesting the market of oil. " Yong Li say if government attack enough, a lot washing the intersection of oil and people will sell " smelt dark oil " the intersection of underground drainage and oil like Lao Zhang (used after an attribute). At present, there are 8 rubbish of kitchen cabinet put on record by the committee of municipal appearance of the city of Beijing registers enterprises, among them only hit real collection, transportation and integration capability processed with waste oil of kitchen cabinet of 3 companies inclusive of China in Beijing. Horse build thoroughbred horse state frankly, existing policies and regulations lack mandatory and binding character, kitchen cabinet waste oil register and it punishes specialization, industrialization to be intensity low. The reporter knows, it has no unified collection to transport the vehicle that 8 are put on record in enterprises, whether it is the treatment of recycle treatment after registering nobody supervises, whether the restaurant gives enterprise which retrieves qualification the waste oil of kitchen cabinet, the supervision department is not clear either, lack corresponding punishment even more. As to this, Ma JianJi says, department's supervision duty of in charge ofing etc. of managing and involving supervising, environmental protection, public security men, city of industry and commerce, hygiene, quality of waste oil of kitchen cabinet, Beijing is studying and setting up long-efficiency supervision mechanism as soon as possible at present. Relevant expert calculate, Beijing annual meal drink oil in 600,000 ton about, calculated by waste oil rate 15%, produce 90,000 tons of waste oil of kitchen cabinet every year, about 60,000- 7 ten thousand tons that can be collected effectively. The reporter knows, there is Beijing there are two enterprises that is smelted ability of melting of biological diesel oil, the amount of production is fewer than ten thousand tons in the whole year, nearly 60,000 tons of other waste oil are under supervising the situation with unidentified duty, whereabouts unknown. Lao Zhou washing the oil and going through in more than 20 years tells reporters, most underground drainage oil is " smelted black oil " Person hands,flow out Beijing,after the peripheral province and city of Beijing refine and process by way of small workshop, mix, stock manufacturer, name of product, date of production and validity one " There is not three " Edible oil reflux dining table, form the intact interests roller chain, it is very difficult for the persons who come to a place for the first time to enter. But the intersection of entry and person for many years, know very well " this life such as previous existence " in oil such as underground drainage like him ,"The oil that we ate is the rapeseed oil brought from the native place. " "And then want to do other things, it is very free to do this and walk. " Lao Zhang tells reporters, 10 years ago, the restaurant should spend money asking them to wash the oil of underground drainage, often invite them to dinner; It is they that spend money buying from restaurant now " Wash the oil right of the underground drainage " ,And the price is raised from one or two thousand yuan of each restaurant for every year to as many as ten thousand yuan at present, more than ten ten thousand even, among the 10 over year, he go through the intersection of underground drainage and the intersection of oil and the intersection of price and constantly upward course, it is obvious the interests are big among them. "Certainly have a cause of increased competition too. " Lao Zhang says, it is from Jiangsu to do this one that walked in the past, many " strangers " have come now ,The oil of underground drainage is snatched away by them at higher price. "For this reason it is an ordinary affair to fight. " Lao Zhang complain, for vie for, come back the intersection of oil and source, have to give the relevant personnel an advantage sometimes, buy back again from them. "Anyway not worry about selling, the more important thing is that can't lose the market. " Lao Zhang's tone strengthens. 3 task of top priority - -As to the transformation of the oil of underground drainage, the question collected is more thorny, it is complicated for the source to make source management very weak, lack and restrain the means horse from building thoroughbred horse to tell reporters, the underground drainage oil that we usually talk about is roughly made up of 4 parts: Fry the goods oil, the quantity of output of fast food restaurants such as McDonald, Kentucky, Ji Ye's family,etc. and large-scale food and beverage enterprise is very great; The oil of underground drainage, the kitchen is arranged and entered and separated the oil in the oil pool, the oil of only narrowly-defined underground drainage by the lower water pipe after the food and beverage shop; Wash the waste oil that animal's viscera produced in the slaughter house; The oil of water from washing rice, namely the waste oil in the rubbish of kitchen cabinet, according to calculating the proportion of waste oil in the rubbish of kitchen cabinet about 5%. "It is complicated for the source to make it seem very weak to produce unit source management to discard the oil at present, lack the source and restrict the means, many departments unites the supervision mechanism and has not taken shape yet. " Ma JianJi says. "The task of top priority is to solve the waste oil of kitchen cabinet and collect the difficult problem. " Ma JianJi says, as to the transformation of the waste oil, the question collected is more thorny. The related departments are setting about making the economic encouragement policies at present, the real such an enterprise of China of Beijing is by way of cooperation while encouraging, it is scattered to combine in individual wash by people on oil,it is collect to advance source of. According to the introduction of Ma JianJi, the committee of municipal appearance of the city of Beijing is fostering the speciality of standardizing the rubbish of kitchen cabinet and discarding the oil and collecting the transportation main body at present, plan to pursue the possession and license the operating service, and and discard the collection of the oil to transport the vehicle and manage the navicert to the rubbish of kitchen cabinet, forbid drawing the vehicle of communications and transportation transporting the rubbish of kitchen cabinet secretly and discarding the oil to set out on a journey and go privately. "Fined 100 yuan each time! " Because private repacks the guest into the goods by the minibus to use the car, Lao Zhang often receives the policeman's punishment, he does not feel very worthwhile. "I want, turn on regular vehicle very much, want, have whom vehicle supervision department authorize can set out on a journey navicert going too, but does not know who is in charge of this, can only be ready to pay the penalty. " "The oil of underground drainage is turned into the diesel oil prospect and had a good prospect very much! " Beijing technological director Liu Su of real China of China thinks, though the biological diesel oil is ignited It is low, can't be used in the fuel of vehicle alone, need mix with the diesel oil of petrochemical industry and using in the proportion of stipulating in the countrying. But as the fuel of car after mixing, can improve the exhaust to discharge effectively, reduces environmental pollution. Standard of our country B5 at present, namely biological diesel oil sneak into petrochemical industry diesel oil a large amount of is 5% most. It is reported, the standard of Europe has already reached B20, namely the mixed proportion of biological diesel oil is up to 20%, even already tried out such mixed diesel oil the plane in Dutch aviation? Pharmaceutical is rare! Bank the intersection of and distant Yu, rose of , wash, slough off the intersection of and the intersection of Ti and protruding the intersection of and Zhan Does the silkworm of Ju room of Huan cherry sigh and prepare against yarn of Lu ? About 0%. The more important thing is that can break off the possibility that the oil of underground drainage returns to the dining table completely because of the change of the chemical property. " Liu Su is emphasized, so long as strengthen the waste oil source and collect management, can well turn waste into wealth, have increasingly many private capital that is aiming at the market of biological diesel oil for the moment. It is reported, China Beijing real China has already bought the land nearby of Yanshan Petrochemical, declaring and setting up and building a biological diesel oil factory of 50,000 tons of annual production capacity. "Believe with the increasing of government's supervision, the oil of underground drainage is retrieved and can unquestionably be realized controllably, our raw materials are out of question. " Lee's harmony is very confident. "Biological diesel oil that produce then will quality stable and reliable, can like now, because do things simply and thriftily, it is discontinous to produce, diesel oil quality is not very steady, some products can only be regarded as the fuel oil which burn the boiler. " Li Yong says. (Reporter Fu ZiMei)
