poster description
Obtaining valuable products from environmental remediation waste is an interesting approach that is capturing the attention of bioenergy scientists worldwide. The use invasive of biomass feedstocks for bioenergy generation requires assessment of the characteristics that influence the process effectiveness and product performance. Water hyacinth (Eichhornia sp.) is an invasive aquatic plant that affects the quality of water resources around the world mainly in tropical and subtropical areas. In the Dominican Republic, Eichhornia sp. are invading two important rivers in Santo Domingo, Ozama and Isabella rivers. E. crassipes and E. Azurea from Ozama and Isabela river were harvested characterized to assess the feasibility of anaerobic digestion to produce biogas and fertilizer. Ash, carbohydrates, and organic elemental analysis as well as inorganic composition of the ash were performed as a preliminary valuation of the anaerobic digestion of this aquatic plant.
