Recent studies on microwave processing of biomass for bioenergy production are reviewed. Statistical review of published research papers related to microwave and biomass was used to classify microwave processing used in bioenergy production. Microwaves have potential for use in various processing methods such as pretreatment, gasification, pyrolysis, transesterification, extraction, liquefaction and drying, to achieve low energy consumption, rapid reaction time, and high production yield. Microwave-assisted processing technologies for the second generation biomass (lignocellulosic biomass) and third generation biomass (algae and seaweeds) are described, as first generation biomass (food crops such as sugar canes, corns and grains) is often discussed as a "fuel versus food" issue. Scale-up strategies and discussions on energy consumption, cost, and efficiency of the microwave processing are also described with reference to specific examples of microwave reactors. Understanding of dielectric properties of biomass mixture is crucially important for designing an efficient and robust microwave reactor. Microwave processing is a future promising technology for renewable energy production, although its industrialization is still unfulfilled.

Algal biomass is an attractive feedstock for sustainable biofuel production because of its high growth rate and the fact that it does not compete with food crops. This review examines progress made in the processing and extraction of microalgal lipids as feedstocks for algae‐derived biofuels. The discussion focuses on lipid extraction processes but also mentions drying, cell disruption, and transesterification processes because of their potential effect on the extraction process, and because of the possibility of performing them simultaneously with extraction. Some of the common themes discussed include the benefits of utilizing wet microalgal biomass, combining process steps (process intensification), and the importance of considering the entire life cycle when assessing the ‘greenness’ of a technology. Lipid extraction technologies will need to be improved for microalgal biofuels to compete effectively with fossil fuels, particularly through the development of energy‐efficient extraction methods and the adaptation of these methods for large‐scale production. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd

The commercial production of carotenoids as bioactive commodities from microalgae has been severely limited due to the nature of the microalgal outer cell matrix. Microwave technology offers a rapid method for obtaining larger amounts of these biochemical compounds. The process facilitates cell‐wall rupture, releasing the inner cell components. Chlorella biomass, raised in an outdoor raceway pond, is used for downstream extraction of carotenoids by following the microwave‐assisted solvent extraction (MAE) approach. The response surface modeling (RSM) strategy was employed to optimize the two independent parameters, power and extraction time, with a two‐level central composite design (CCD). Acetone, hexane, methanol, hexane : acetone (1:1), hexane : ethanol (7:3) were used as solvents of choice. Acetone gave a total carotenoid yield of 0.061 ± 0.003 mg gm−1 under optimum microwave power and time; 130 W and 1.69 min. The optimized yield from hexane was 0.00173 ± 0.005 mg gm−1 with an exposure time of 1 min to 100 W. The total carotenoid yield of the methanol‐based extraction batch was 0.0371 ± 0.004 mg gm−1 with 157 W and 1 min of extraction time. The solvent mixtures of hexane : acetone gave 0.0398 ± 0.002 mg gm−1 (185 W for 1.7 min) and hexane : ethanol gave 0.0383 ± 0.004 mg gm−1 (195 W, 1.6 min), respectively. The results indicate a satisfactory outcome to the process. They also show microwave‐based extraction to be a fast, economic, reproducible, and repeatable method in comparison with the conventional strategies used for recovering the sensitive natural pigments. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd
