The invention relates to a hydrocyanic acid containing bioresource carbon, and to a method for producing a raw material mainly containing the same by reacting ammonia with methane or methanol optionally in the presence of air and/or oxygen, characterised in that at least one of the reagents selected from ammonia, methane and methanol is obtained from a biomass. The invention also relates to the uses of the raw material for producing acetone cyanohydrin, adiponitrile, methionine or methionine hydroxy-analog, and sodium cyanide.
