Shellfish aquaculture has developed rapidly, and the annual production of shell waste by‐products exceeds 10 million tons. The reutilization of shell waste is a severe problem in terms of environmental protection and the development of the circular economy. Due to its limited economic value, shell waste has generally been discarded or sent to landfill without any further processing and reutilization, thereby wasting resources and severely degrading the coastal ecosystem. This review summarizes recent research into the reutilization of shell waste, including applications in the fields of agriculture, construction, environmental protection, chemical production, food additives and biomaterials. Problems and strategies related to the reutilization of shell waste are analysed in order to provide technical support for the large‐scale and high value‐added utilization of shell waste.

Trends in Widely Used Catalysts for Fatty Acid Methyl Esters (FAME) Production: A Review

et al. 2021

The effective transesterification process to produce fatty acid methyl esters (FAME) requires the use of low-cost, less corrosive, environmentally friendly and effective catalysts. Currently, worldwide biodiesel production revolves around the use of alkaline and acidic catalysts employed in heterogeneous and homogeneous phases. Homogeneous catalysts (soluble catalysts) for FAME production have been widespread for a while, but solid catalysts (heterogeneous catalysts) are a newer development for FAME production. The rate of reaction is much increased when homogeneous basic catalysts are used, but the main drawback is the cost of the process which arises due to the separation of catalysts from the reaction media after product formation. A promising field for catalytic biodiesel production is the use of heteropoly acids (HPAs) and polyoxometalate compounds. The flexibility of their structures and super acidic properties can be enhanced by incorporation of polyoxometalate anions into the complex proton acids. This pseudo liquid phase makes it possible for nearly all mobile protons to take part in the catalysis process. Carbonaceous materials which are obtained after sulfonation show promising catalytic activity towards the transesterification process. Another promising heterogeneous acid catalyst used for FAME production is vanadium phosphate. Furthermore, biocatalysts are receiving attention for large-scale FAME production in which lipase is the most common one used successfully This review critically describes the most important homogeneous and heterogeneous catalysts used in the current FAME production, with future directions for their use.

Material with negative value such as grease trap waste appears to be a cost‐effective feedstock for biodiesel production since it can be collected at little to no charge. Owing to its high lipid content, fatty acid methyl ester can be produced from grease trap waste via a two‐step production process with methanol, using potassium hydroxide as the catalyst. However, there are several process parameters that could affect the yield of the fatty acid methyl ester produced. In this study, the optimum conditions for biodiesel production were 6:1 methanol‐to‐oil molar ratio, 1.5 wt% potassium hydroxide loadings, a 40 °C reaction temperature and a 2 h reaction time, resulting in a fatty acid methyl ester yield of 87%. Further purification using 0.05 g L−1 of biobased adsorbent from woodchip biomass for a 1 h residence time at 25 °C yielded the highest removal of free fatty acid and soap at 98.2 and 67.9%, respectively. This study not only demonstrates the potential of grease trap waste as a bioresource for the production of biodiesel, but also proves an interesting and additional use of bio‐based adsorbent from woodchip biomass as an effective tool in biodiesel purification since the quality of biodiesel produced within the standard EN14214. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.
