Variations in Production and Oligomers Content Obtained Under Hydrothermal Treatment Among Five Fast-Growing Species

In order to identify fast growing species utilizable for olygomer and monomer production, five fast growing species ( Paulownia fortunei, Chamaecytisus proliferus, Arundo donax, Leucaena.diversifolia and Sesbania grandiflora ) were tested. Concurrently, the biomass productivity of these species was also tested on a field scale. The biomass productivity of the selected species studied ranges from 0.36 to 21.30 t ha -1 (o.d.b.) under Mediterranean conditions for the year 1 sprouts. In addition, the hydrothermal treatment results show that the selected species could be employed as alternative raw material for the production of oligomers, leading to a high concentration of oligomers (9.4-23.4 g/L -1 at 190ºC).
