Abstract: The presence of sargassum on the Caribbean coasts affects the environment and one of the region’s main economic activities: tourism. The collection of sargassum and its use for the generation valuable products is important to mitigate the costs associated to the control of this weed. The anaerobic co-digestion of sargassum with relevant organic waste for the production of biogas, and fertilizers, is an alternative for the integrated management of these materials in the tourism industry. The objective of this work was to evaluate the effect of different percentages of sargassum on the quality of biogas, the rate of methane production, and the biofertilizer characteristics during its anaerobic co-digestion with food waste. Biodigesters of 1200 L were fed with 0.7 kg/day of food waste and sargassum at concentrations ranging from 45% to 100% for 30 days. The results showed a direct relationship between the food waste percentage and the methane production.
