2015 Energy Procedia  
Seagrass (Halodule uninervis) native to Abu Dhabi was sampled in various locations thorough February to June 2013. Chemical composition was analyzed, which included ash, extractives, structural carbohydrates, acid insoluble residue and CHNSO content. The theoretical methane yield was calculated based on the CHN content using Buswell's formula. Anaerobic digestion was performed with the use of sewage sludge. Three concentrations of seagrass biomass were tested (1%, 3%, 5% of VS) to evaluate the
