Biomass: Advanced Strategies for Renewable Chemicals and Energy Production

Topic Information

Dear Colleagues,

The Topic “Biomass: Advanced Strategies for Renewable Chemicals and Energy Production” explores cutting-edge approaches to converting biomass into valuable products that can serve as alternatives to fossil fuels. This encompasses a range of technologies, strategies, and processes focused on the sustainable production of energy and chemicals from renewable biomass resources. These include the utilization of diverse biomass feedstocks—such as agricultural residues, algae, and waste—and their conversion into biofuels, biochemicals, and energy using thermochemical and biochemical processes like pyrolysis, gasification, and fermentation. Emerging technologies such as biorefineries, which integrate multiple conversion processes and optimize biomass utilization, are also included. Furthermore, research focuses on producing advanced biofuels (e.g., cellulosic ethanol, bio-jet fuel), renewable chemicals (e.g., bioplastics, platform chemicals), green energy (e.g., biogas, hydrogen), and the integration of Power-to-X technologies in the form of electro- and photo-catalytic processes within modern bio refineries and fermentation routes. It also considers catalytic advances such as the development of new catalysts for more efficient biomass conversion into high-value chemicals and fuels. Challenges such as feedstock variability, biomass recalcitrance, and economic feasibility are addressed through advances in catalysis, genetic engineering, and techno-economic assessments. Further, life cycle assessments help to ensure that these processes contribute to environmental sustainability.

With this, the Topic is strongly dedicated to the dissemination of innovative research that advances the use of biomass as a sustainable resource for chemicals and energy, contributing to the transition to renewable, low-carbon systems.

Microplastics (MPs), as frequent pollutants, persist in aquatic environments and have an impact on the growth and biomass production of microalgae. This study employed MPs of polyethylene (PE), polystyrene (PS), and polypropylene (PP) at concentrations of 250 mg/L with MP sizes of 50, 100, 300, and 500 µm to investigate their influences on the growth and bio-production of Scenedesmus quadricauda. The results revealed that MPs suppressed the growth of S. quadricauda and increased algal lipid production. The order of the MPs in terms of their inhibitory and lipid production effect was the following: PP > PS > PE. The order of their size sensitivity was 50 > 100 > 300 > 500 µm. In the 50 µm PP culture, the inhibition of microalgal growth (inhibition rate: 49.26%) and accumulation of lipids (total lipid content: 65.40%) were most significant, especially with neutral lipid content. Additionally, scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR) analyses proved that the rough MP surface led to high aggregation of microalgae, reduced the intensities of the protein-, lipid-, and carbohydrate-related bands and affected the structure of the algal cells.

Renowned for its versatility in environmental applications, biochar exhibits substantial potential to enhance anaerobic digestion, facilitate carbon sequestration, and improve water treatment through its highly efficient adsorption mechanisms. This study focuses on biochar derived from pineapple crown biomass, produced through slow pyrolysis, and its efficiency in removing organic dyes from contaminated water. The structural, morphological, and surface properties of both biochar and chemically activated biochar samples were comprehensively characterized using a range of techniques, including XRD, FTIR, XPS, BET surface area analysis, and SEM microscopy. The adsorption performance was evaluated using methylene blue (MB), rhodamine B (RhB), and malachite green (MG) dyes as model contaminants, with particular emphasis on the contact time on dye removal efficiency. Initial results showed removal rates of 10.8%, 37.5%, and 88.4% for RhB, MB, and MG, respectively. Notably, chemical activation significantly enhanced the adsorption efficiency, achieving complete (100%) removal of all tested dyes. Complete adsorption of MB and MG occurred within 9 min, indicating rapid adsorption kinetics. Adsorption data fit well with pseudo-second-order kinetics (R² = 0.9748–0.9999), and the Langmuir isotherm (R² = 0.9770–0.9998) suggested monolayer adsorption with chemical interactions between dyes and biochar. The intraparticle diffusion model further clarified the adsorption mechanisms. These findings demonstrate the efficacy of activated biochar for dye removal and highlight the potential of pineapple crown biomass in environmental remediation. Full article
