Energy and Wild Plants as Renewable Resources for the Production of Biocomposites and Biofuels

The research involved four different feedstocks derived from annually renewable resources (Virginia mallow, Arundo donax and Gigant Miscanthus) and from abundant waste (Spanish Broom). Applied biomass was used to produce fibers and biofuels. Solid waste from the fibres production which amounts up to 50%, presents valuable resource to be used to produce biofuel. According to the principles of green chemistry to design safer products and to use safer solvents and reaction conditions, harsh alkali solvents were substituted with environmentally friendlier solutions. Reaction conditions and energy efficiency were improved in a way that instead of high consumption of electric energy, microwave energy was used for the pretreatment of biomass in the production of textile fibres. Excellent energy properties were confirmed with the results of high values of carbon and hydrogen. The results revealed that 2.2-2.6 kg of plants is required for the production of 1 kg of fuel, confirming our assumption of acceptability of chosen ligno- cellulosic biomass for the production of high- quality fuel.
