Summary: The use of rice husk in a laboratory-scale biofilter to remove heavy metals was studied. Langmuir isotherms showed the best correlation for Cd(II), Cu(II), and Cr(VI) removal, with a maximum operating temperature of 303.15 K and maximum removal efficiency at pH 9.0 for Cd(II) and Cu(II), and pH 3.0 for Cr(VI). Blockage times were found to be the longest at h=0.55 for Cd(II), and h=0.40 for both Cu(II) and Cr(VI).

Summary: To improve the biogas yield of rice straw, an innovative cascade utilization process named FSD was proposed, which involves first digestion, NaOH treatment, and second digestion. Lab-scale batch experiments were conducted to study the effect of first digestion time on biogas production and lignocellulose structure destruction. Results showed that the FSD-15 process yielded the highest biogas production and had significant effects on the composition and structure of rice straw. Therefore, FSD-15 is recommended for cascade utilization of rice straw in biogas production.

Summary: In this study, the potential of two less explored fungal strains, Trichoderma longibrachiatum (TL) and Pycnoporus sanguineus (PS), in improving the hydrolysis and bioavailability of rice straw in anaerobic digestion (AD) was evaluated. The fungal treatment of rice straw for 10 days by TL and PS increased biogas production and reduced soluble chemical oxygen demand (sCOD). The microbial communities in treated samples showed increased diversity, contributing to better process performance and enhanced resilience against pH fluctuations.

Summary: The study explores the potential of sulfate-reducing bacteria (SRB) rich in hydrogenase enzyme activity for hydrogen production and examines the effects of different metal co-factors concentrations on hydrogen production efficiency. The results show that Fe2+ and Se4+ ions play a crucial role in hydrogenase expression in SRB, while the impact of Ni2+ ions on hydrogenase expression is minor. A higher Acetate/Butyrate ratio is favorable for increased hydrogen production. The application of potential further enhances hydrogen production.

Summary: The study found that the partial pressure of volatiles is the root cause of accelerating biomass decomposition and deoxygenation in gas-pressurized torrefaction. It can be seen as a self-promoted deoxygenation process consisting of three stages. These findings have implications not only for gas-pressurized torrefaction, but also for pressurized pyrolysis and gasification of biomass.

Summary: Bio-based polymers are a class of polymers made by living organisms, with only a few known and commercialized so far. They have not been widely applied due to poor mechanical strength and economic constraints, but have become suitable candidates for biological applications. As consumers become more aware of the environmental impact of petrochemical polymers and the global transition away from long-lasting plastics, there is increasing interest in previously unattainable sectors. Bio-based polymers can be direct replacements or completely novel polymers, such as polylactide, with improved technical specifications. Polylactic acid (PLA) has gained recognition as a biodegradable thermoplastic for use in 3D printing, particularly in extrusion-based technologies. This review examines the chemical structure, manufacturing techniques, standard features, and market situation of PLA, focusing on its use in extrusion-based 3D printing with highlighted examples of 3D-printed PLA items.

Summary: Newly BC producing bacteria were successfully isolated from acidic fruits, with the most potent producer identified as Achromobacter S3. Mango peel waste (MPW) hydrolysate was found to be a significant alternative medium for BC production, with the yield increased from 0.52 g/L to 1.22 g/L. The physicochemical analysis showed that BC produced by Achromobacter S33 on HS and MPW media had crystallinity of 72% and 79% respectively, and the topographical study revealed nanofibers with a diameter of approximately 10 nm and a length of 200 nm.

Summary: The objective of this study was to use pulping by-product (black liquors) as an effective component in preparing high surface area carbon nanostructure adsorbents. The results showed that the adsorption capacities of the carbon nanostructures from black liquor-based aerogels were higher than those without black liquors. Different pulping reagents and dyes had different effects on the adsorption capacities. The black liquor from pulping with alkaline reagents provided the highest adsorption capacity for methylene blue, while the sulfite reagent provided the highest adsorption capacity for brilliant blue.
