A machine shaped like a safe runs in the kitchen of a hotpot restaurant in chengdong, southwest China's chengdu, Jan. 21, 2007. Restaurant workers carry a large pot of leftover hot pot soup into the machine. After a while, the water in the soup is drained away from the sewer, the remaining residue and the waste oil in the soup are separated and put into two tanks.

　　This amazing machine is called an oil-water separator. Its function is to facilitate the oil processing enterprises to take away the waste oil and process it into biodiesel, so as to realize the utilization of waste oil resources. However, the vast majority of restaurants in sichuan are currently uninstalled, with only sporadic trials. The recycling of waste oils and fats has hit a bottleneck, frustrating bosses who only a few years ago were aiming to make a go of it in biodiesel.

　　Business complaints at both ends of the blocked, the company is facing suspension

　　Sichuan zhongming new energy technology co., LTD. General manager wang jinhua saw the reporter began to complain, "for oil things headache is not a day two days." His company specialises in reprocessing gutter oil into biodiesel feedstock, but because it cannot receive the oil, it has long been producing at 30-40 per cent of its designed capacity.

　　The upstream failed to receive the waste oil, and the downstream failed to sell the biodiesel due to the continuous decline in the market price of refined oil. Both sides were blocked, and the company was faced with suspension of production. The 2,000 tons of biodiesel raw oil were still in the warehouse and dared not sell.

　　Zhongming's plight is not unique. Wang jinhua is also President of the chengdu association for the reuse of waste oil resources. According to statistics, eight biodiesel production enterprises under the association have all experienced similar situations. Chengdu produces about 1200 tons of slops every day. According to the waste oil rate of 25%, 300 tons of slops can be produced, but in fact, only a part of them can be received by the eight biodiesel production enterprises. "The popularity of the oil and water separator is the first prerequisite for the utilization of waste oil and oil resources, as well as a necessary measure for garbage classification and collection." Wang jinhua said that the vast majority of restaurants in sichuan do not install oil-water separator, which has created an embarrassing situation, restaurants can only serve slops, and biodiesel processing enterprises do not clean slops.

　　Restaurant making fun of slops oil treatment, the machines are expensive and troublesome

　　Besides the biodiesel business, liu jianming, general manager of chengdu huanyate technology co., LTD., has a headache. His company developed a fully enclosed oil-water separator in October last year and began marketing, but the market in sichuan is progressing slowly. It has only done a dozen pilots in chengdu and received the first order of 2,000 units in zunyi, guizhou province.

　　Why the slow advance? Liu jianming told reporters that the emergence of a new thing, there is always an acceptance process, an oil and water separator 3000-5000 yuan cost, who will pay the money, is the biggest problem.

　　Restaurants don't want to pay. Liu junzhen, owner of a Chinese restaurant on qing yunan street in chengdu, admitted that he would not buy a slops separator to deal with slops oil. "it's easy to sell it to the guerrillas," he said.

　　In 2014, 18,000 catering companies in jilin province installed oil-water separators, all free of charge. Guizhou zunyi to chengdu huanyate technology co., LTD. Booked 2000 sets of oil and water separator, are also provided to the restaurant free of charge.

　　Experts recruit the government, restaurants, enterprises, cooperation to promote

　　The oil and water separator installed by damiao hotpot restaurant, no. 11, narrow-alley, is provided free of charge by the biodiesel processing enterprise, and the hotpot restaurant has signed a waste oil and grease purchase agreement with the enterprise.

　　Sichuan hotel and catering entertainment industry association President he tao told reporters that the use of this method, some of its member enterprises installed free of charge oil-water separator.

　　Liu jianming is also keen to find this solution, the target customer positioning for biodiesel enterprises.

　　Mr. Wang is looking at a site where he plans to invest 180 million yuan to build a new standard plant. After separating food waste from oil, water and slag in a restaurant, the waste oil and solid waste are pulled back into the factory. Waste oil is refined into biodiesel, solid waste residue is converted into biogas, which is extracted into new energy power fuel for cars, and the remaining waste residue is used as fertilizer for organic vegetables or garden seedlings. In this way, all the kitchen waste can be turned into treasure.

　　Wang jinhua is also in talks with liu jianming's huanyate technology, and is ready to rent and install oil-water separator from catering enterprises for free. These catering enterprises will provide all waste oil and grease to processing enterprises for payment. "It's a win-win-win. First, the restaurant business has zero cost and profits. Second, waste oil processing enterprises do not worry about raw materials; Third, it has solved the government's worries about food safety and environmental protection."

　　Mr. Wang said it was also important for the government to issue relevant rules on entry. In Shanghai, for example, since 2011 install oil-water separator is included in the "entry" of new food and beverage enterprise, or catering service permit issued by the food and drug supervision departments will not be issued by the entry-exit inspection and quarantine departments will not be port health permits, the environmental protection department shall not be approved the environmental impact assessment documents, advancing the effect is very obvious. "To get the oil and water separator through the door, the government has to push."

　　BianHou

　　To deal with slops oil, before usually think of, is how to prevent the beforehand guard against death, after the event how to severely punish, prevention. Now, with the specialized technology and the companies willing to do it, the promise of solving social problems and turning waste into treasure has been thwarted.

　　Machines can not enter the restaurant, waste oil can not be collected, slops oil may flow to the table.

　　In fact, it is not difficult to solve the problem. There are two reasons: one is economic, the other is legal.

　　The reluctance of restaurants to add oil-water separators and of companies to charge high prices for waste oil is simply a matter of cost. Account, from both sides can be calculated: the oil receiving enterprises to the restaurant can provide free oil and water separator, at the same time with a reasonable price to obtain a stable oil source guaranteed by the contract; Government departments already have expenditures on environmental protection and public health, which can be converted into tax incentives and special subsidies for oil companies.

　　Moreover, gutter oil concerns environmental protection and public health. Advanced, safe, hygienic treatment should be taken as mandatory requirements, industry access conditions, oil can be taken as franchising.
