Manufacture of biofuel harms agriculture
9 November 2007Replacement of oil, coal and gas with biofuel becomes more and more urgent problem. Now the word “biofuel” is, as a rule, regarded as the hi-tech products, received from agricultural crops or waste of processing of vegetative and animal raw material, which almost do not pollute an atmosphere.
However, in the near future interest in alternative energy sources can decrease considerably on a background of a sharp rise in prices on wheat and palm oil. In this connection many biofuel companies have attended to search of new kinds of plants, which can be used for manufacture of “green fuel”.
Especially sharply this problem has risen recently, on a background of new high prices for oil -100 doll./barr. Also because of growth of anxiety concerning ecology of a planet, the companies search for plants at which processing the small amount of hotbed gases would be allocated. And new crops can become quite good replacement of grain crops which now are the basic source of biofuel.
However, it is necessary to note, it is not so easy: some plants can appear dangerous - for example, encroaching for crops of other cultures negatively affects irrigation canals, especially in the western areas of America, where are problems with water deliveries. The majority scientists believe that new kinds of plants for biofuel can help to lower deficiency, but before it they should be studied carefully.
But, on the other hand, such plants as the Chinese reed have one doubtless advantage - they are poorly subject to wreckers and illnesses. It, in turn, makes them very attractive to the biofuel companies.
Cellulose is one more variant of replacement of habitual plants. So, Bush’s administration has already enclosed millions dollars in the companies, which are going to build in factories on manufacture of cellulose ethanol. However, experts do not share their optimism.
