Türkisch-libanesische Beziehungenes both as an energy source and as raw materials for polymers and plastics . There is increasing pressure for a wider utilization of biomass feed-stocks for specialty items. The total biomass produced on earth is estimated as approximately 170 billion tons, of which a very small portion, less than 4%, is used. .
