“…The C:N for floating mixed Sargassum mats floating close to the coast of Nigeria can be estimated from the data of Oyesiku and Egunyomi [16] to be around 23. Although Lapointe et al [5] found no significant difference between the C:N ratio of S. natans and S. fluitans, the C:N ratio found by Wan et al [37] for S. natans was only 7. Milledge and Harvey [34] found the C:N ratio of S. muticum to be 8.…”

Abstract:In recent years there have been massive inundations of pelagic Sargassum, known as golden tides, on the beaches of the Caribbean, Gulf of Mexico, and West Africa, causing considerable damage to the local economy and environment. Commercial exploration of this biomass for food, fuel, and pharmaceutical products could fund clean-up and offset the economic impact of these golden tides. This paper reviews the potential uses and obstacles for exploitation of pelagic Sargassum. Although Sargassum has considerable potential as a source of biochemicals, feed, food, fertiliser, and fuel, variable and undefined composition together with the possible presence of marine pollutants may make golden tides unsuitable for food, nutraceuticals, and pharmaceuticals and limit their use in feed and fertilisers. Discontinuous and unreliable supply of Sargassum also presents considerable challenges. Low-cost methods of preservation such as solar drying and ensiling may address the problem of discontinuity. The use of processes that can handle a variety of biological and waste feedstocks in addition to Sargassum is a solution to unreliable supply, and anaerobic digestion for the production of biogas is one such process. More research is needed to characterise golden tides and identify and develop commercial products and processes.

“…For the liquid products obtained at 400 °C, the qualitative and quantitative gas chromatography analyses were able to determine the concentrations of six organic compounds, namely acetone, methanol, ethylbenzene, n-pentadecane, n-pentadecene, and furfuryl alcohol. In comparison with the pyrolysis of seaweeds (Enteromorpha clathrata and Sargassum natans) [33], the typical compounds derived from the decomposition of lignins (e.g., phenol) or lipids (e.g., n-pentadecane, n-pentadecene) were identified.…”

“…Overall yield of bio-oil derived from the pyrolysis of seaweed is lower than that from lignocellulosic biomass something that has been attributed to the high ash content of seaweed and the presence of metal ions [68,69]. High potassium content caused high char yields and reduced bio-oil yields [67,68], but copper ions have been shown to promote the onset of pyrolysis in alginate polymer and Laminaria digitata [70].…”

“…Oxygen content has been found to be reduced in bio-oils through the use of catalysts during pyrolysis of Laminaria japonica, such as zeolites, but this approach also led to a decrease in the overall yield of bio-oil and increased the amount of gaseous products [78]. Pyrolysis oils from both microalgae and macroalgae also contain nitrogen compounds (which on combustion generate harmful NOx gases), which must be removed and hence incur additional fuel refining costs [69,79].…”

Macroalgae-Derived Biofuel: A Review of Methods of Energy Extraction from Seaweed Biomass

et al. 2014

View full text Add to dashboard Cite

Abstract:The potential of algal biomass as a source of liquid and gaseous biofuels is a highly topical theme, but as yet there is no successful economically viable commercial system producing biofuel. However, the majority of the research has focused on producing fuels from microalgae rather than from macroalgae. This article briefly reviews the methods by which useful energy may be extracted from macroalgae biomass including: direct combustion, pyrolysis, gasification, trans-esterification to biodiesel, hydrothermal liquefaction, fermentation to bioethanol, fermentation to biobutanol and anaerobic digestion, and explores technical and engineering difficulties that remain to be resolved.
