Summary: Facing increasing mobility, energy demand, and the need to mitigate climate change, developing sustainable and eco-friendly alternatives to fossil fuels is a crucial task for humanity. Biofuels and synthetic fuels show great potential as they can be integrated into existing processes, with synthetic fuels from CO2 and renewable energies being considered the next big step towards a sustainable and ecological future. In our study, we focus on the sustainable production of ethanol and isobutanol, two common biofuels, using methanol and xylose derived from CO2 and lignocellulosic waste streams. Through enzyme and reaction optimization, we successfully produced ethanol or isobutanol from xylose and methanol. Our research opens up the possibility of hybrid production of biofuels and chemicals from CO2 and lignocellulosic waste streams, providing an alternative to conventional routes that rely solely on CO2 or sugars.

Summary: Brown algae have attracted attention as a potential energy source due to their ability to adsorb CO2 and store carbon. This review paper discusses the cultivation and biorefinery process of brown algae, and examines the opportunities, challenges, and future prospects of brown algae-based biofuels in North America. The analysis suggests that biomass-derived fuels, including brown algae biofuels, will play a significant role in the transportation sector. However, the commercial cultivation of brown algae and meeting market demands remain the main challenges for the algal biofuels industry. Expanding the value chain of brown algae biorefinery by producing advanced biofuels and value-added by-products could have a significant impact on North American countries' GDP.

Summary: This study assessed the effects of mixing energy cane juice with corn on fermentation parameters and found no negative effects. However, contamination with Lactobacilli significantly increased the production of organic acids and reduced the ethanol content. Therefore, effective disinfection before fermentation is essential for the integration between corn and cane on an industrial scale. Ionizing radiation showed promise as a disinfection control method, but further economic viability studies are needed.

Summary: The bioprocessing of lignocellulosic biomass to produce bio-based products is gaining global attention under biorefinery setup. However, the commercial success at industrial scale is still inadequate due to irregular biomass supply chain, market uncertainties, and scale-up challenges. Global research efforts by public and private sectors are underway to achieve deeper market penetration for the commercial success of lignocellulosic biorefineries.

Summary: The study found that increasing temperature and mixture ratio significantly increases the yield of biocrudes in hydrothermal liquefaction, with the best results achieved at 340 degrees C and a 1:7 mixture ratio. The high heating values of the biocrude and solid residue were significantly better than those of the raw material, and the main components of the biocrudes were identified as fatty acids, amides, N-containing compounds, and cyclic ketones using advanced GCxGC/TOF-MS technology.

Summary: A new integrated methodology was developed to estimate the environmental impacts of bioethanol production from sugarcane bagasse in Mexico. The methodology included five modelling phases: bibliometric analysis, simulation, life cycle inventory, life cycle assessment, and analysis of major environmental burdens. The study found that the biofuel production and biofuel use in vehicles stages had the highest contributions to greenhouse gas emissions.

Summary: The bioeconomy and biomass production play an important role in the EU economy, with high expectations for various industries in the future. However, the demand exceeds sustainable supply capacity. To address this, it is suggested to fully integrate organic chemistry into the bioeconomy, while also achieving the recycling of wastes, residues, and CO2.
