2007年6月21日 生物燃料:从牲畜口中夺食?
8年前,中国的专家治国论者提出了一个如何处理政府巨量玉米储备的计划,因为这些储备就要变质。 Eight years ago, China's technocrats came up with an idea for what to do with the government's vast stockpile of corn reserves, a stockpile that was going stale. The plan was to transform the corn into starch, sweeteners or ethanol, which could be blended with gasoline to run cars. The move would create valuable products and potentially reduce China's oil dependency. Now there is growing concern that creating biochemical and biofuels industries worked too well. The stale corn reserves are used up and there is increasing competition for fresh supplies between rapidly growing industrial processors and livestock farmers who rely on it as feed for animals. Several provinces have made mandatory the use of a fuel with 10 per cent ethanol content and China has set a target of meeting 15 per cent of its transportation energy needs with biofuels by 2020. Using 3.3m tonnes of corn, it produced 1m tonnes of ethanol last year. Rising food and grain prices have propelled higher levels of inflation since last October, says Liao Qun, chief China economist for Citic Ka Wah bank. In April, the food price index rose 7.1 per cent, pushing inflation near a two-year high of 3 per cent. The search for corn sent China, the world's second-biggest corn producer, back into international markets in 2005 for the first time since the mid-1990s. Only 70,000 tonnes were imported last year but that amount is likely to soar to 24m tonnes by 2020. That level would match the current intake of Japan, the world's largest corn importer. Wang Xiaohui, a director at the China National Grain and Oils Information Centre, has said that China's corn exports might shrink 60 per cent to 2m tonnes in the year to the end of September 2008, while imports could rise to 500,000 tonnes. China produced about 143m tonnes of corn last year. Patrick Yu, vice-president of Cofco, China's largest crops processor, warns that China's industrial corn users might be encouraged to source overseas to allay food security fears and help ease domestic inflation. The government has halted approvals for new corn-based ethanol plants and is developing alternative biofuels using non-food crops |
