Plastic from GM potatoes underway in Germany

Field trials at the University of Rostock, Germany, are assessing genetically modified potatoes, which can be used to obtain a biodegradable plastic. Scientists at the Berlin-based university have developed a protein called cyanophycin, a biodegradable plastic, from potato tubers and leaves. According to researchers it is possible to produce biodegradable polymers (biopolymers) in plants which could act as renewable raw materials supplying substitutes for petroleum-based plastics that are not biodegradable. In addition, cyanophycin also contains the amino acid arginine, which improves animal health. Researchers are also investigating possible procedures for extracting the cyanophycin cheaply from the crop. Trials show that even simple procedures are capable of extracting up to 80 per cent pure cyanophycin as a white powder. It accounts for as much as 6 per cent of the dry weight of potatoes.
