“…The upcycling of urban waste into recyclable solid acid catalysts is another promising approach for converting biomass-derived platform molecules into high-value chemicals. Municipal solid waste, including plastics, paper, and organic residues, can be transformed into functional catalysts through pyrolysis, activation, and surface modification techniques. − These catalysts exhibit superior catalytic activity, stability, and recyclability compared to traditional homogeneous or heterogeneous catalysts. For instance, urban waste pine needles-derived acidic catalyst PiNe-SO 3 H has been used by Campana et al for producing a range of levulinates beyond ethyl levulinate (EL) .…”

Bioenergy possesses the potential to alleviate our energy demands while maintaining renewability and carbon neutrality. The utilization of abundant biomass sources for bioenergy production presents a significant challenge. When considering chemical processes for conversion, the development of effective catalysts becomes imperative as they play a pivotal role in biomass-to-bioenergy/biofuel conversion. In such scenarios, heterogeneous nanoporous materials emerge as crucial components for facilitating catalytic conversion. This perspective provides a comprehensive summary of biomass, including its classification, valorization processes and applications along with recent advancements in various catalytic systems utilized for transforming biomass and its intermediates into renewable energy products. We delved into the diverse classes of heterogeneous catalysts, including metal-based, metal oxide-based, silica based, hybrid catalysts, and organic polymers, highlighting their unique structural and compositional features that influence catalytic activity and selectivity. Furthermore, we discussed the importance of pore structure, surface area, and active site accessibility in enhancing catalytic performance. By examining the advantages and limitations of different catalysts, we provide insights into the rational design and optimization of porous heterogeneous catalysts for efficient and sustainable bioenergy conversion. This perspective serves as a valuable resource for researchers and engineers in the field of renewable energy, seeking to develop innovative catalyst materials for biomass valorization.

Vetiver root is widely used to produce essential oils in the aromatherapy industry. After the extraction of oil, the roots are disposed of as waste. The central objective of this research was to explore the conversion of this waste into a resource using a circular economy framework. To generate biochar, vetiver roots were pyrolyzed at different temperatures (300, 500, and 700 °C) and residence times (30, 60, and 120 min). Analysis showed the root biochar generated at 500 °C and held for 60 min had the highest surface area of 308.15 m2/g and a yield of 53.76%, in addition to other favorable characteristics. Comparatively, the surface area and the yield of shoot biochar were significantly lower compared to those of the roots. Repurposing the spent root biomass for environmental and agronomic benefits, our circular economy concept prevents the plant tissue from entering landfills or the waste stream.

“…Diverse catalysts, such as metal oxides [9], carbon materials [10], and natural minerals [11], have been exploited to catalyze persulfate. Among them, carbon materials derived from biomass waste, e.g., crop straw (which is often named biochar), show great advantages in being easily available in raw materials, having a tunable structure, and being industrially and economically attractive [12]. Nevertheless, the catalytic efficiency of pristine biochar is relatively lower than that of transition metal-based catalysts.…”

A boron and iron co-doped biochar (B-Fe/biochar) from Masson pine bark was fabricated and used to activate peroxydisulfate (PDS) for the degradation of guaiacol (GL). The roles of the dopants and the contribution of the radical and non-radical oxidations were investigated. The results showed that the doping of boron and iron significantly improved the catalytic activity of the biochar catalyst with a GL removal efficiency of 98.30% within 30 min. The degradation of the GL mainly occurred through the generation of hydroxyl radicals (·OHs) and electron transfer on the biochar surface, and a non-radical degradation pathway dominated by direct electron transfer was proposed. Recycling the B-Fe/biochar showed low metal leaching from the catalyst and satisfactory long-term stability and reusability, providing potential insights into the use of metal and non-metal co-doped biochar catalysts for PDS activation.
