“…Microalgae grow rapidly with small quantities of water per kg of biomass, produce a large number of lipids and starch for biofuel synthesis, and are capable of sequestering CO 2 from flue gas [62,63]. Macroalgae are multicellular marine organisms with low concentrations of cellulose and lipid and high levels of structural polysaccharides but no lignin content [64]. Macroalgae, also called seaweed, are capable of growing to up to 60 m in length [65].…”

Biofuel, a cost-effective, safe, and environmentally benign fuel produced from renewable sources, has been accepted as a sustainable replacement and a panacea for the damaging effects of the exploration for and consumption of fossil-based fuels. The current work examines the classification, generation, and utilization of biofuels, particularly in internal combustion engine (ICE) applications. Biofuels are classified according to their physical state, technology maturity, the generation of feedstock, and the generation of products. The methods of production and the advantages of the application of biogas, bioalcohol, and hydrogen in spark ignition engines, as well as biodiesel, Fischer–Tropsch fuel, and dimethyl ether in compression ignition engines, in terms of engine performance and emission are highlighted. The generation of biofuels from waste helps in waste minimization, proper waste disposal, and sanitation. The utilization of biofuels in ICEs improves engine performance and mitigates the emission of poisonous gases. There is a need for appropriate policy frameworks to promote commercial production and seamless deployment of these biofuels for transportation applications with a view to guaranteeing energy security.

“…A biorefinery entails a number of raw materials, intermediate products, and final products that are processed or produced by several unit operations [1,14]. At the same time, biorefinery processes need to operate sustainably by minimizing water and energy use and waste generation [15,16]. Zero waste efforts treat residues to secondary renewable feedstocks for other processes through reduction, recycling, reuse or recovery of solid and liquid byproducts resulting from microalgal biomass production [15].…”

“…Algae cultivation, conducted in open raceway ponds or photobioreactors, has been extensively covered in the literature [15,27,28] and will not be repeated here. Obtaining the final microalgal product cost-effectively and sustainably in a biorefinery requires a series of sequential unit operations depending on the particular species of microalgae employed [25].…”

Prospects of Microalgae for Biomaterial Production and Environmental Applications at Biorefineries

Microalgae are increasingly viewed as renewable biological resources for a wide range of chemical compounds that can be used as or transformed into biomaterials through biorefining to foster the bioeconomy of the future. Besides the well-established biofuel potential of microalgae, key microalgal bioactive compounds, such as lipids, proteins, polysaccharides, pigments, vitamins, and polyphenols, possess a wide range of biomedical and nutritional attributes. Hence, microalgae can find value-added applications in the nutraceutical, pharmaceutical, cosmetics, personal care, animal food, and agricultural industries. Microalgal biomass can be processed into biomaterials for use in dyes, paints, bioplastics, biopolymers, and nanoparticles, or as hydrochar and biochar in solid fuel cells and soil amendments. Equally important is the use of microalgae in environmental applications, where they can serve in heavy metal bioremediation, wastewater treatment, and carbon sequestration thanks to their nutrient uptake and adsorptive properties. The present article provides a comprehensive review of microalgae specifically focused on biomaterial production and environmental applications in an effort to assess their current status and spur further deployment into the commercial arena.
