The genetically modified poplars were planted a year and a half ago. The Institute says that they are a suitable source of bio fuels including bio ethanol.
The modified poplars also have a different composition allowing greater production. Paper manufacturing using these poplars is also far more environmentally friendly.
The poplar project has been a controversial one and also triggered action in the courts. The Climate and Public Health ministers attempted to stop the test, but the Council of State gave the go-ahead.
