新华社海牙７月１１日电（记者 潘治 报道员 姜慧）一家荷兰生物燃料公司将从中国采购“地沟油”生产生物燃料的新闻，让对“地沟油”回流餐桌憎恶已久的公众拍手称快。然而，尽管西方“地沟油上天”已经成真，但就此期待中国“地沟油”找到合理归宿并不现实。

    The xinhua news agency the Hague July 11 (Reuters)（Reporter PanZhi newsman JiangHui）A Dutch biofuel company will from the procurement“Hogwash oil”Biofuels news，To let“Hogwash oil”Backflow table abhor already a long time of the public ChenKuai clap your hands。however，Although western“Hogwash oil god”Has come true，But in China look forward to“Hogwash oil”Find reasonable end-result is not reality。

    首先要澄清的是，东西方的“地沟油”有很大差别。西方食用油用得最多的是煎炸，“地沟油”成分相对简单；而在中国厨艺中食用油的用法多样，“地沟油”也成分复杂。荷兰能源公司ＳｋｙＮＲＧ执行董事迪尔克·克罗内迈耶向新华社记者介绍说，该公司用以制取生物燃料的“地沟油”是指煎炸后的废油，这种“地沟油”在回收阶段污染较小，而中国“地沟油”并非全部可用于制作生物燃料。

    First to make clear is that，The east and the west“Hogwash oil”There was a big difference between。Western oil the most used is Fried，“Hogwash oil”Composition relatively simple；And in Chinese cooking oil in the usage of the varied，“Hogwash oil”Also complicated composition。The Dutch energy company SkyNRG executive director John Deere g · crowe mayer (xinhua news agency) in to introduce said，The company to biofuel production“Hogwash oil”Refers to the frying oil，this“Hogwash oil”In the recovery phase less pollution，China“Hogwash oil”Not all can be used to produce biofuels。

    其次，尽管生物燃料在全球被普遍看好，但现阶段，以生产生物燃料为目标的“地沟油”回收体系难以形成经济规模，短期内大面积推广有难度。克罗内迈耶介绍说，地沟油制成生物燃料的成本在逐年降低，但“这是个长期过程”。然而，“地沟油”回流餐桌问题关乎公众健康，急迫需要解决，不能“长期”等到其成本降至大规模推广的地步。

    second，Although biofuels in global heavily favored，But at the moment，In the production of biofuels is the goal“Hogwash oil”Recycling system is difficult to form the economies of scale，In the short term the widespread have difficulty。Crowe, mayer said in introduced，Hogwash oil of biofuels made from the cost reducing year by year，but“This is a long-term process”。however，“Hogwash oil”Backflow table for public health problem，Urgent needs to solve，Can't“long-term”Wait until the cost down to the point of large-scale promotion。

    再者，从航空领域的生物燃料现状来看，“地沟油”也不是最佳原料。生物燃料来源于生物质，是地球上储量最丰富的可再生资源，在交通运输行业主要包括乙醇燃料、生物柴油和生物航空煤油。生物酶制剂巨头丹麦诺维信公司的高级研发经理吴桂芳博士告诉记者，生物航空煤油的原料来源有厨余废油和木本油料作物，“前者由于来源分散、原料还能应用于诸多其他领域，所以发展受限较多；而后者前景更广阔。”

    moreover，From the field of biofuels to the current situation，“Hogwash oil”Also is not the best materials。Biological fuel from biomass，Is the most abundant reserves of renewable resources，In transportation industry mainly including ethanol fuel、Biodiesel and biological kerosene。Enzyme preparation giant Denmark novozymes' senior r&d manager WuGuiFang doctor told reporters，Biological kerosene of the sources of the raw materials have more than hutch oil and woody oil crops，“The former because scattered sources、Raw material also can be applied to many other areas，So development more limited；While the latter more broad prospect。”

    诺维信公司提供的资料显示，生物燃料目前已经在交通运输用燃料方面获得了广泛使用，预计到２０５０年可替代２７％的交通运输用燃料，但“地沟油”并非这一巨大市场中最具竞争力的原料。

    Novozymes provide data shows，Biofuels at present already in transportation fuel with has a widely used，It is estimated that by 2050 alternative 27% of transportation fuel use，but“Hogwash oil”Not such a huge market in the most competitive raw materials。

    吴桂芳介绍说：“从目前的技术来看，在生物燃料整体领域里，纤维素乙醇是全球普遍看好的生物燃料发展趋势。”纤维素乙醇的优势不仅在于现有技术成熟，已经有较大规模的生产和应用，而且对于促进农村经济发展、提高空气质量有重要意义。除了以农林废弃物和城市固体垃圾为原料，纤维素乙醇还可以用边角土地种植的能源作物为原料，方便产业化。

    WuGuiFang introduced said：“From the current technology to see，On biofuels in the whole field，Cellulose ethanol is global generally optimistic about biofuel development trend。”The advantage of cellulosic ethanol is not only existing mature technology，Have a large-scale production and application，And to promote the development of rural economy、Improve air quality to have the important meaning。In addition to the forestry waste and city solid waste as raw material，Cellulose ethanol can also use the marginal land planted energy crops as raw material，Convenient industrialization。

    由此看来，制造生物燃料“飞天”只是“地沟油”的众多出路之一，既不是唯一也未必最佳。加强监管、法规严控，并拓展其他用途，才是解决“地沟油”回流餐桌问题的正途。

    So it，Make biofuels“flying”just“Hogwash oil”One of the many way，Neither the only also are not always the best。Strengthening the supervision、Regulations tight control of，And develop other purposes，Is to solve“Hogwash oil”Backflow table problem for glory。
