To adhere to climate targets, there is a need to find alternative, circular carbon sources. One key contributor is biogenic residues. This paper determines the spatially explicit technical carbon potential of 23 residue streams from four different origin classes. The goal is to calculate the carbon potential for green methanol production as feedstock for the German chemical industry. While the physical carbon potential is dominated by cereal straw and logging residues, the theoretical carbon potential shows a broader distribution across residue streams. The mobilisable theoretical carbon potential demonstrates that by-products of the wood processing industry and wood shavings, which are currently primarily used for energy purposes, have a high relevance for material applications instead. In terms of the final technical potential, cereal straw (3.72 Mt<ce:inf loc=\"post\">C</ce:inf>/a) and green waste (3.67 Mt<ce:inf loc=\"post\">C</ce:inf>/a) are leading contributors. The carbon potentials show spatial inhomogeneities across the NUTS3 regions. This information, together with the classification of districts according to their dominant origin class, provides key insights for the siting of large-scale chemical recycling plants. The total technical carbon potential (without economic considerations, dependent on H<ce:inf loc=\"post\">2</ce:inf> supply) for the mean scenario ranges from 7.20–14.69 Mt<ce:inf loc=\"post\">C</ce:inf>/a, which is equal to 90–184% of the expected feedstock carbon demand for green methanol. With increasing competition around biogenic residues, this study provides a spatially resolved basis for assessing their potential role in defossilising carbon supply chains.","PeriodicalId":253,"journal":{"name":"Biomass & Bioenergy","volume":"57 1","pages":""},"PeriodicalIF":6.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148884161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fuel-quality, combustion, and life-cycle inventory data were obtained from the authors' previous studies and subsequently refined through additional testing and data validation. Socio-economic and socio-technical performance was assessed using context-specific expert input. The alternatives were ranked using WSM-AHP and MULTIMOORA-AHP, while pathway-specific GHG savings were calculated according to the RED II/III methodology and compared with the 80 % requirement for heat installations entering operation from 2026. Brewer's spent grain and wood pellets formed the leading group in the overall multi-criteria assessment. Buckwheat husk and sunflower husk pellets received the lowest consolidated MULTIMOORA-AHP scores. When only technical criteria were considered, wood pellets ranked above brewer's spent grain pellets, demonstrating the influence of deployment-related criteria on the complete assessment. All pathways except hemp pellets met the 80 % GHG savings requirement, while grass pellets remained closest to the threshold at 82 %. Processing-energy requirements and use-phase emissions were the principal sources of variation in pathway-specific GHG savings. By contrasting multi-criteria preference with GHG compliance, the proposed approach identifies alternatives that would be evaluated differently by either assessment alone and supports the assessment of pellet pathways lacking directly applicable RED II/III default values.","PeriodicalId":253,"journal":{"name":"Biomass & Bioenergy","volume":"20 1","pages":""},"PeriodicalIF":6.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148884160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their effects across micro- and nanometre length scales remain poorly understood. This study therefore investigates how feedstock and process conditions affect properties of pine wood biochar produced in industrially relevant pilot-scale continuous reactor for torrefaction (291–315°C, 6–12 min) and pyrolysis (350–400°C, 25 min). High-resolution X-ray microtomography combined with AI-assisted image analysis was used to quantify earlywood–latewood distribution, porosity, pore size, cell wall thickness, and micrometre-scale surface area, while N<ce:inf loc=\"post\">2</ce:inf> and CO<ce:inf loc=\"post\">2</ce:inf> sorption probed nanometre-scale structure. The wood microstructure was largely preserved across treatments, resulting in highly anisotropic pore networks. Porosity remained high (33–77%), primarily influenced by earlywood–latewood variability rather than temperature. From torrefaction to pyrolysis, cell wall thickness and pore diameter decreased, while microporosity (<∼0.7 nm) and accessible surface area increased significantly above 350°C. Discrepancies between N<ce:inf loc=\"post\">2</ce:inf> and CO<ce:inf loc=\"post\">2</ce:inf> measurements indicate differences in pore accessibility, likely associated with ultramicroporosity, pore constrictions and/or partially inaccessible pores. Water holding capacity ranged from 1.7 to 5.3 times dry weight, with highest average at 350°C, although differences were not significant. Combined use of microtomography and gas sorption provides a multiscale framework for linking biochar structure across micro- and nanometre scales to performance-relevant properties. These findings demonstrate that wood anatomy dominates over process conditions under mild thermal treatment, highlighting new possibilities for tailoring process design through consideration of wood anatomy.","PeriodicalId":253,"journal":{"name":"Biomass & Bioenergy","volume":"43 1","pages":""},"PeriodicalIF":6.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148884163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, understanding how thermochemical pretreatments influence combustion behavior is essential. However, limited studies have evaluated the combustion performance of torrefied and densified biomass under conditions representative of practical applications, rather than relying solely on thermogravimetric analyses. This study investigated the combined effects of torrefaction and briquetting on the physicochemical properties and combustion performance of sugarcane bagasse. Torrefaction was conducted at different temperatures, followed by densification and comprehensive material characterization. Thermogravimetric analysis and bench-scale combustion tests were performed to assess combustion behavior and performance indicators. Pearson correlation analysis was conducted to evaluate the relationships between chemical and physical properties. The results showed that torrefaction progressively increased the fuel ratio, indicating enhanced carbonization; however, the fuel ratio improvement did not directly translate into better combustion performance. Instead, the highest combustion performance, as indicated by the combustion index, was achieved under mild torrefaction conditions. Furthermore, samples subjected to higher torrefaction temperatures exhibited reduced structural integrity, leading to faster but less stable combustion behavior after densification. Overall, the findings demonstrate that better combustion performance in densified torrefied biomass is not achieved at the highest torrefaction temperature, but within a range where a balance between chemical upgrading and physical structure is maintained.","PeriodicalId":253,"journal":{"name":"Biomass & Bioenergy","volume":"15 1","pages":""},"PeriodicalIF":6.0,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148884355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, an eco-efficient strategy is proposed for the comprehensive valorization of whole mango byproducts (MBPs), including peels and finisher pulp (PeP), seed tegument (SeT), and kernel (SeK), into functional bioplastics intended for food packaging. To disrupt the organized biomass structure for subsequent assembly into films, MBPs were subjected to mild hydrothermal pretreatment (HTP) or dilute alkaline pretreatment (DALP), which selectively partitioned amorphous biomass components and induced distinct structural responses according to the mango byproduct. While HTP better preserved solubilized carbohydrates, DALP promoted more extensive pectin saponification and hemicellulose solubilization. Bioplastic films were then prepared using pretreated PeP, SeK, or a mixture of all byproducts (PePSe). The incorporation of only 10% carboxymethyl cellulose (CMC) improved film mechanical performance, yielding tensile strength values of up to 11 MPa. The SeK-based films exhibited the lowest water vapor permeability (2.3 g mm kPa<ce:sup loc=\"post\">−1</ce:sup> h<ce:sup loc=\"post\">−1</ce:sup> m<ce:sup loc=\"post\">−2</ce:sup>), and all CMC-containing films displayed hydrophobic surfaces (water contact angle > 90°). All bioplastics provided near-total UVA and UVB shielding (>97%), while the PeP-based films exhibited the highest transparency (>43%). Although the antioxidant activity of the bioplastics decreased compared to that of the corresponding raw MBPs, the PeP-DALP-CMC film retained at least 50% of it. By demonstrating that biomass heterogeneity can be harnessed, rather than eliminated, to tailor functional bioplastics, this simple and effective approach emerges as a potentially scalable strategy for producing sustainable active packaging materials.","PeriodicalId":253,"journal":{"name":"Biomass & Bioenergy","volume":"43 1","pages":""},"PeriodicalIF":6.0,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148884186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper examines the multi-technology synergic mechanisms underpinning regional OWtE systems in China, analyzing the technical, economic, environmental, and policy dimensions of four primary conversion pathways: anaerobic digestion (AD), incineration with energy recovery, pyrolysis, and gasification. Drawing on provincial data, life cycle assessment outcomes, and techno-economic evaluations, the study proposes an integrated framework for regional OWtE manufacturing utilization. The findings demonstrate that hybrid systems combining AD with thermal treatment can reduce greenhouse gas emissions by 58 to 68 percent relative to landfilling while achieving levelized energy costs of 42 to 82 USD per MWh. Regional differentiation in technology deployment is driven by waste composition, economic development level, and feedstock availability.
