Special Issue Information

Dear Colleagues,

Escalating energy demand and abnormal climate change are two of the major problems facing humankind in the 21st century. The utilization of renewable energy sources, especially biomass, as alternatives to fossil fuels in the fields of chemicals, fuels and materials is one of the promising solutions for a more sustainable and environmentally friendly society. 

The term biomass includes a variety of vegetal and animal resources, such as crops, agricultural waste, forestry, green plants, but also animal and domestic wastes. Biomass of vegetal origin is present mostly in the form of lignocellulose with an estimated global annual production over 10 billion tons (dry basis). Hence, the facile and affordable technologies for lignocellulosic biomass valorization are very important, not only for energy supply, but also as the roles in environmental protection and carbon emission reduction.  

This Special Issue, "Advances in Conversion of Biomass for Chemicals, Fuels and Materials", seeks high-quality works on the effective processes and technologies related to conversion of biomass to chemicals, fuels, and materials. We welcome original research papers and reviews related to (but are not limited to) the following themes:

  • Conversion of biomass (including cellulose, hemicellulose and lignin);
  • Depolymerization of biomass (including cellulose, hemicellulose and lignin);
  • Hydrodeoxygenation of biomass-derived compounds for fuels;
  • Valorization of biomass-derived compounds for chemicals;
  • Conversion of biomass for materials.

The process of looking for alternative energy sources is driven by the increasing demand for energy and environmental contamination caused by using fossil fuels. Recent investigations reported the efficiency of microalgae for biofuel production due to its low cost of production, high speed of growth, and ability to grow in harsh environments. In addition, many microalgae are photosynthetic, consuming CO2 and solar light to grow in biomass and providing a promising bioenergy source. This review presents the recent advances in the application of microalgae for biofuel production. In addition, cultivation and harvesting systems and environmental factors that affect microalgae cultivation for biofuel production have also been discussed. Moreover, lipid extraction and conversion technologies to biofuel are presented. The mixotrophic cultivation strategy is promising as it combines the advantages of heterotrophy and autotrophy. Green harvesting methods such as using bio-coagulants and flocculants are promising technologies to reduce the cost of microalgal biomass production. In the future, more investigations into co-cultivation systems, new green harvesting methods, high lipids extraction methods, and the optimization of lipid extraction and converting processes should be implemented to increase the sustainability of microalgae application for biofuel production.

Algae have the potential to be used as a feedstock for the synthesis of valuable compounds and biofuels. In addition, algal waste can be further transformed into biofuel, biogas, and biochar using different thermochemical processes such as microwave pyrolysis, pyrolysis, torrefaction, and hydrothermal conversion. Due to its high specific surface area, rapid electron transport, and graphitic carbon structure, algal biochar carbonized at high temperatures has shown outstanding performance for applications as CO2 adsorbents, supercapacitors, and persulfate activation. Due to the combination of various functional groups and porous structures, the algae biomass pyrolysis at a moderate temperature produced high-quality biochar that shows high performance in terms of pollutant removal, while low-temperature pyrolysis produces coal fuel from algae via torrefaction. Over time, there have been exponentially more petroleum-based polymers created that have harmful impacts on both humans and the environment. As a result, researchers are becoming more interested in algae-based biopolymers as a potential alternative strategy for establishing a sustainable circular economy globally. The advantages of microalgal biopolymer over other feedstocks are its capacity to compost, which provides greenhouse gas credits, its quick growth ability with flexibility in a variety of settings, and its ability to minimize greenhouse gas emissions.
