Biomethanation potential of macroalgae Ulva spp. and Gracilaria spp. and in co-...
Costa, J. C.; Gonçalves, P. R.; Nobre, A. M.; Alves, M. M.Biochemical methane potential of four species of Ulva and Gracilaria genus was assessed in batch assays at mesophilic temperature. The results indicate a higher specific methane production (per volatile solids) for one of the Ulva sp. compared with other macroalgae and for tests running with 2.5% of total solids (196 ± 9 L CH4 kg−1 VS). Considering that macroalgae can potentially be a post treatment of municipa...
Integrated system for macroalgae production and conversion into biogas
Nobre, A.; Gonçalves, P. R.; Costa, J. C.; Alves, M. M.Recently research on energy from macroalgae is being reconsidered driven by the following factors: fuel price increase, CO2 mitigation policies and interest on renewable energy sources after the Kyoto protocol, and need for energy crops not competing with land for food production. However, the commercial expansion of this energy source is limited by its economic feasibility. In this presentation we analyse the ...
