This paper focuses on the synthesis of ethylene from various biomass feedstocks, with ethanol as a transitional chemical platform. Four different production routes are investigated: two first-generation pathways using sugarcane and cereal crops (e.g., corn), and 2 s-generation alternatives based on lignocellulosic materials (e.g., corn stover, wheat straw). An analysis orientated to technological performance and economic feasibility comparison is established in depth. The reference facility is modelled with an annual output of approximately 117,000t of ethylene, which would be suitable for industrial-scale deployment. The project results include material and energy balances, along with a financial evaluation using metrics such as the Net Present Value (NPV) and the Minimum Ethylene Selling Price (MESP). Among all scenarios addressed, no route initially emerges as an economically viable option under current assumptions. However, it can be stated that the sugar-based ethylene production pathway reaches the best economic results, producing an NPV of -€173M€ at current ethylene prices and an MESP of €1265/t of ethylene. The remaining pathways require cost reductions (i.e., reducing biomass purchasing cost, maintenance and overhead, and consumptions) to achieve profitability. Sensitivity analyses state the significant influence of biomass procurement costs and market price fluctuations on economic outcomes. Overall, the findings of this research underscore the promise of bioethylene as a value-added chemical, supporting broader efforts toward decarbonization.

本文主要研究了以乙醇为过渡化工平台，以多种生物质原料为原料合成乙烯。研究了四种不同的生产途径：使用甘蔗和谷类作物（如玉米）的两种第一代途径，以及基于木质纤维素材料（如玉米秸秆、小麦秸秆）的第二代替代品。建立了面向技术性能和经济可行性比较的深入分析。参考设施的模拟年产量约为117,000吨乙烯，适合工业规模的部署。项目结果包括材料和能源平衡，以及使用净现值（NPV）和最低乙烯销售价格（MESP）等指标进行财务评估。在所有讨论的方案中，在当前假设下，没有一条路线最初是经济上可行的选择。然而，可以说，糖基乙烯生产途径达到了最佳的经济效果，按当前乙烯价格计算，其净现值为- 1.73亿欧元，MESP为1265欧元/吨乙烯。其余途径需要降低成本（即减少生物质采购成本、维护和间接费用以及消耗）以实现盈利。敏感性分析表明，生物质采购成本和市场价格波动对经济成果有重大影响。总的来说，这项研究的发现强调了生物乙烯作为一种增值化学品的前景，支持更广泛的脱碳努力。

The shift to sustainable energy systems is crucial in response to climate change and declining fossil fuel reserves. This thorough review examines routes to renewable methanol production, highlighting its significance in achieving energy transition targets and advancing environmental sustainability. Renewable methanol, produced from biomass, absorbs carbon dioxide (CO₂) from industrial emissions, and renewable hydrogen offers a viable alternative to conventional, carbon-intensive methanol produced from fossil fuels. Although international research on renewable methanol is growing, a notable gap remains in its use in regions in regions with industrial hubs (such as Gladstone, Australia), where no prior evaluations have been conducted.

The paper analyses various renewable methanol production methods, emphasising the integration of these resources, which significantly reduces emissions. This integration positions renewable methanol as a pivotal sustainable energy source for achieving energy transition and climate goals in regional hubs such as Gladstone. It also discusses cross-sector applications, such as marine fuels and energy storage, positioning renewable methanol as a key enabler of circular economy models. Challenges related to cost, scalability, and regulatory support are identified, alongside innovations in process integration. According to the life cycle assessment discussed in this review, renewable methanol produced through the integration of renewable sources can reduce greenhouse gas emissions by up to 90 % relative to fossil-based methanol. The findings lay a foundation for future research in any industrial hub and highlight the strategic role of renewable methanol in the transition of both regional and global energy systems.

向可持续能源系统的转变对于应对气候变化和化石燃料储量下降至关重要。这篇全面的综述考察了可再生甲醇生产的路线，强调了其在实现能源转型目标和促进环境可持续性方面的重要性。由生物质生产的可再生甲醇可以吸收工业排放的二氧化碳（CO2），而可再生氢则为化石燃料生产的传统碳密集型甲醇提供了可行的替代方案。尽管国际上对可再生甲醇的研究正在增长，但在工业中心地区（如澳大利亚的格莱斯顿）的使用方面仍存在显著差距，这些地区没有进行事先评估。本文分析了各种可再生甲醇生产方法，强调了这些资源的整合，这大大减少了排放。这一整合将可再生甲醇定位为实现格莱斯顿等区域中心能源转型和气候目标的关键可持续能源。报告还讨论了海洋燃料和能源储存等跨部门应用，将可再生甲醇定位为循环经济模式的关键推动者。除了流程集成中的创新之外，还确定了与成本、可伸缩性和监管支持相关的挑战。根据本文讨论的生命周期评估，与化石甲醇相比，通过整合可再生能源生产的可再生甲醇可减少高达90%的温室气体排放。这些发现为未来在任何工业中心的研究奠定了基础，并强调了可再生甲醇在区域和全球能源系统转型中的战略作用。

Phosphorus (P) is essential for plant growth, however, global reliance on non-renewable phosphate rocks raises sustainability concerns, particularly in countries like Brazil that heavily depend on imported P fertilizers. Bone char, a byproduct of animal bone pyrolysis, has emerged as a promising alternative P source due to its hydroxyapatite content and circular economy potential. However, its moderate solubility limits agronomic efficiency for short-cycle crops. This study investigated a novel approach to enhance P solubility by acidifying bone char with phosphoric acid (H₃PO₄). Bone chars were produced at different pyrolysis temperatures, characterized by X-ray diffraction, attenuated total reflectance Fourier transform infrared spectroscopy, and scanning electron microscopy, and compared to commercial sources with high and low solubility (triple superphosphate and Bayóvar, respectively). Solubility tests, P release and diffusivity studies, and incubation trials were conducted alongside greenhouse experiments with maize in a highly weathered clayey soil. The characterization of acidified bone char (bone char-H₃PO₄) showed the peaks of the hydrated monobasic calcium phosphate, bands for the phosphate ions, high solubility of P in water, and the presence of the elements C, O, P, and Ca. Bone char-H₃PO₄ demonstrated increased P solubility and cumulative release, with similar performance to triple superphosphate in both P uptake and biomass production. Despite lower soil P availability observed in incubation, bone char-H₃PO₄ supported high agronomic efficiency, highlighting its potential as a sustainable and effective alternative P fertilizer. Additionally, bone char retained carbon in its structure, offering added benefits for soil health and climate-smart agriculture.

磷(P)对植物生长至关重要，然而，全球对不可再生磷矿的依赖引发了对可持续性的担忧，特别是在巴西等严重依赖进口磷肥的国家。骨炭是动物骨热解的副产品，由于其羟基磷灰石含量和循环经济潜力，已成为一种有前途的替代磷源。然而，其适度的溶解度限制了短周期作物的农艺效率。本研究研究了一种用磷酸（H3PO4）酸化骨炭以提高P溶解度的新方法。通过x射线衍射、衰减全反射傅立叶变换红外光谱和扫描电镜对不同热解温度下的骨炭进行了表征，并与高溶解度和低溶解度的商业来源（分别为三元过磷酸钙和Bayóvar）进行了比较。溶解度试验、磷释放和扩散性研究以及培养试验与温室试验一起在高度风化的粘土土壤中进行。酸化后的骨炭（骨炭- h3po4）表现出水合磷酸氢钙峰、磷酸离子带、磷在水中的高溶解度，以及元素C、O、P和Ca的存在。骨炭- h3po4显示出磷的溶解度和累积释放增加，在磷吸收和生物量生产方面具有与三重过磷酸钙相似的性能。尽管在孵育过程中观察到较低的土壤磷有效性，但骨炭- h3po4支持较高的农艺效率，突出了其作为可持续和有效的替代磷肥的潜力。此外，骨炭在其结构中保留了碳，为土壤健康和气候智能型农业提供了额外的好处。

Scenedesmus obliquus BR003 exhibits rapid growth and tolerance to high CO₂ levels, making it suitable for large-scale cultivation and carbon sequestration. It produces biofertilizers, a more sustainable alternative to chemical fertilizers. In this study, S. obliquus was cultivated in a mixing board tank with weekly injection of 595 g of CO₂ from flue gas, producing 0.14 g/L biomass. The resulting biofertilizer contained 50 % organic carbon and essential nutrients (N, P, and K). Maize experiments with six treatments and five replications revealed that treatments T2 (biofertilizer with inorganic P and K) and T4 (inorganic NPK) demonstrated superior agronomic performance. However, T2 increased soil carbon content while T4 reduced it. With 75.6 % fixation of the injected CO₂, S. obliquus immobilized 7.42 g of carbon per 5.84 g of biofertilizer applied, underscoring its potential to mitigate emissions and support sustainable agriculture.

Renewable and short-season bamboo is a potential feedstock to produce pyrolytic sugars (e.g., levoglucosan) that can be upgraded into liquid fuels and chemicals. However, cellulose in bamboo is tightly intertwined with lignin and hemicellulose, forming a high recalcitrance and complex composition, resulting in hindering the effective release of levoglucosan during fast pyrolysis. The novel route of bamboo pretreated by deep eutectic solvents (DESs) coupled with fast pyrolysis was proposed for producing pyrolytic sugars. The results showed that the bamboo pretreated by choline chloride (ChCl)/formic acid (FA) produced the levoglucosan yield of 198.6 mg/g via fast pyrolysis, increased by about 43 times as compared to raw bamboo, while the relative contents of phenols and acids were significantly reduced. The characteristic analysis showed that the activation energy of the pretreated sample is in a direct proportional relationship with the crystallinity index. The change of crystallinity index and removal of lignin and AAEMs promoted the levoglucosan formation. This work provides an effective route to convert highly resistant lignocellulose into pyrolytic sugars via fast pyrolysis.

可再生和短季节的竹子是生产热解糖（例如左旋葡聚糖）的潜在原料，可以升级为液体燃料和化学品。然而，竹子中的纤维素与木质素和半纤维素紧密缠绕，形成了高顽固性和复杂的成分，阻碍了快速热解过程中左旋葡聚糖的有效释放。提出了用深度共晶溶剂（DESs）预处理竹材并结合快速热解制备热解糖的新途径。结果表明，经氯化胆碱/甲酸预处理的竹材快速热解左旋葡聚糖的产率为198.6 mg/g，比原料竹材提高了约43倍，而酚类和酸类的相对含量显著降低。特性分析表明，预处理样品的活化能与结晶度指数成正比关系。结晶度指数的变化以及木质素和aaem的去除促进了左旋葡聚糖的形成。本研究为通过快速热解将高抗性木质纤维素转化为热解糖提供了一条有效途径。

Developing a simple, efficient, and environmentally benign pretreatment strategy for fractionating lignocellulosic biomass into high-value components remains a critical challenge. Traditional approaches rely on corrosive chemicals or toxic solvents to cleave lignin-carbohydrate bonds. This study introduces a microwave-assisted deep eutectic solvent (MW-DES) system consisting of choline, urea, and water, enabling zero-waste fractionation of corncob. This one-pot process enhances enzymatic saccharification of cellulose via swelling-enhanced accessibility, allows efficient recovery of xylo-oligosaccharides, and facilitates the extraction of lignin–carbohydrate complexes (LCCs) and their continuous nanonization—collectively enabling the comprehensive valorization of all biomass components. The swelling effect of MW-DES on cellulose and its ability to mediate nucleophilic cleavage of ester and ether bonds in lignocellulose were verified using model compounds. Under 120 °C pretreatment, lignin removal efficiency reached 69.17 %, while enzymatic hydrolysis of cellulose afforded a glucose yield of 83.97 %. Spherical LCC nanoparticles (LCCNP) were obtained at a yield of 61.09 %, an average diameter of 380.29 nm, and a zeta potential of −30.39 mV. Xylan residues enhanced colloidal stability, and LCCNP demonstrated radical scavenging capacity comparable to alkaline lignin. When incorporated into poly(vinyl alcohol) films, LCCNP improved tensile strength by 15.53 %, increased water contact angle by 82.34°, and afforded >85 % UV-shielding efficiency. This work establishes a sustainable lignocellulose refining strategy that transforms agricultural residues into high-value product streams: fermentable sugars for biofuel production and nanofillers for biodegradable packaging. Integrating efficiency, environmental compatibility, and full biomass valorization, this MW-DES approach addresses key limitations of conventional pretreatment methods while advancing circular bioeconomy principles.

开发一种简单、高效、环保的预处理策略，将木质纤维素生物质分馏成高价值组分仍然是一个关键的挑战。传统的方法依靠腐蚀性化学物质或有毒溶剂来切割木质素-碳水化合物键。介绍了一种由胆碱、尿素和水组成的微波辅助深度共熔溶剂（MW-DES）系统，实现了玉米芯的零废弃物分馏。这种一锅工艺通过膨胀增强可及性，增强纤维素的酶解糖化，允许低聚木糖的有效回收，并促进木质素-碳水化合物复合物（lcc）的提取及其连续纳米化-共同实现所有生物质成分的全面增值。通过模型化合物验证了MW-DES对纤维素的溶胀作用及其介导木质纤维素中酯键和醚键亲核裂解的能力。在120℃预处理条件下，木质素的去除率达到69.17%，而纤维素酶解的葡萄糖收率为83.97%。得到球形LCC纳米粒子（LCCNP），产率为61.09%，平均直径为380.29 nm， zeta电位为- 30.39 mV。木聚糖残基增强了胶体稳定性，LCCNP显示出与碱性木质素相当的自由基清除能力。当加入到聚乙烯醇薄膜中时，LCCNP的抗拉强度提高了15.53%，水接触角增加了82.34°，并提供了>； 85%的紫外线屏蔽效率。这项工作建立了一种可持续的木质纤维素精炼策略，将农业残留物转化为高价值的产品流：用于生物燃料生产的可发酵糖和用于可生物降解包装的纳米填料。这种MW-DES方法集效率、环境兼容性和全生物质增值于一体，在推进循环生物经济原则的同时解决了传统预处理方法的主要局限性。

Spherical LCC nanoparticles (LCCNP) were obtained at a yield of 61.09 %, an average diameter of 380.29 nm, and a zeta potential of −30.39 mV. Xylan residues enhanced colloidal stability, and LCCNP demonstrated radical scavenging capacity comparable to alkaline lignin. When incorporated into poly(vinyl alcohol) films, LCCNP improved tensile strength by 15.53 %, increased water contact angle by 82.34°, and afforded >85 % UV-shielding efficiency. This work establishes a sustainable lignocellulose refining strategy that transforms agricultural residues into high-value product streams: fermentable sugars for biofuel production and nanofillers for biodegradable packaging. Integrating efficiency, environmental compatibility, and full biomass valorization, this MW-DES approach addresses key limitations of conventional pretreatment methods while advancing circular bioeconomy principles.</div></div>","PeriodicalId":253,"journal":{"name":"Biomass & Bioenergy","volume":"209 ","pages":"Article 108978"},"PeriodicalIF":5.8,"publicationDate":"2026-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145973905","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}

Food and garden organics (FOGO) account for up to 60 % of domestic waste in Australia. Landfilling FOGO leads to significant environmental issues, including methane (CH₄) production and soil and water contamination. While methane capture is undertaken at sanitary landfills, significant losses result in greenhouse gas (GHG) emissions. This study assesses the integration of AD with pyrolysis/gasification to enhance energy and resource recovery from digestate. Results showed that biochar derived from FOGO digestate exhibited high carbon content (32 %–37 %) and fixed carbon (25 %–44 %), indicating that a substantial portion of the total carbon was in a stable, non-volatile form, suitable for long-term carbon sequestration. However, the FO: GO ratio did not significantly affect biochar properties, as AD stabilized feedstocks and reduced volatile matter content prior to thermal treatment. Furthermore, pyrolysis at a 65FO:35GO ratio produced biochar with lower ash and higher fixed carbon and heating value than gasification. Also, when the gasification temperature of the 65FO:35GO feed increased from 700 °C to 900 °C, fixed carbon rose from 22.2 % and volatile matter decreased from 21.8 %. PFAS in biochar were undetectable, and PAHs remained below the detectable limits of 0.0002. The mass and energy balances indicate that energy recovery from biogas and biochar is 481.5 MJ and 39.1 MJ, respectively. In the current study, the circular economy framework is defined through closed-loop resource and energy recovery and is demonstrated using mass and energy balances rather than a technoeconomic assessment. Overall, this study's findings demonstrate the potential of integrating AD with thermal treatments for sustainable resource recovery.

食品和花园有机（FOGO）占澳大利亚家庭垃圾的60%。垃圾填埋FOGO会导致严重的环境问题，包括甲烷（CH4）的产生以及土壤和水污染。虽然甲烷捕获是在卫生填埋场进行的，但大量损失导致温室气体（GHG）排放。本研究评估了AD与热解/气化的结合，以提高消化物的能源和资源回收。结果表明，从FOGO沼液中提取的生物炭具有较高的碳含量（32% - 37%）和固定碳含量（25% - 44%），表明其中相当一部分碳以稳定、不挥发的形式存在，适合长期固碳。然而，氧化石墨烯与氧化石墨烯的比例并没有显著影响生物炭的性质，因为AD稳定了原料并降低了热处理前的挥发分含量。此外，与气化相比，以65FO:35GO的比例热解产生的生物炭具有更低的灰分、更高的固定碳和热值。同时，当气化温度从700℃提高到900℃时，固定碳从22.2%上升，挥发分从21.8%下降。生物炭中PFAS未检出，PAHs仍低于0.0002的检出限。质量和能量平衡表明，沼气和生物炭的能量回收率分别为481.5 MJ和39.1 MJ。在目前的研究中，循环经济框架是通过闭环资源和能源回收来定义的，并通过质量和能量平衡而不是技术经济评估来证明。总的来说，这项研究的发现证明了将AD与热处理相结合以实现可持续资源回收的潜力。

With the ongoing energy transition and growing demand for sustainable development, producing ethylene from second-generation (2G) biomass represents a promising strategy for reducing carbon emissions and ensuring a renewable energy supply. In this study, four bio-ethylene production pathways are conceptualized and evaluated: biomass fermentation to ethanol (BFtE), biomass gasification to syngas and ethanol (BStE), biomass syngas fermentation to ethanol (BSFtE), and direct chemo-catalytic conversion of cellulose to ethanol (BCtE). A comprehensive techno-economic analysis (TEA) and life cycle assessment (LCA) are conducted to compare the economic and environmental performance of these routes. TEA results reveal that the BSFtE route has the lowest minimum selling price (MSP) at $801/t ethylene, demonstrating a clear economic advantage over the BFtE ($1175/t), BStE ($964/t), and BCtE ($2072/t) routes. LCA findings show that in terms of global warming potential (GWP), the BStE route has the lowest GWP at −1.78 kg CO₂ eq./kg ethylene, followed by BFtE (−1.59 kg), BSFtE (−0.36 kg), and BCtE (+2.73 kg). Overall, the BSFtE route offers the best overall balance of economic and environmental performance, making it the most promising alternative to fossil-based ethylene production.

随着能源转型和可持续发展需求的不断增长，从第二代（2G）生物质中生产乙烯是减少碳排放和确保可再生能源供应的一种有前途的战略。本研究对四种生物乙烯生产途径进行了概念化和评估：生物质发酵制乙醇（BFtE）、生物质气化制合成气和乙醇（BStE）、生物质合成气发酵制乙醇（BSFtE）和纤维素直接化学催化转化为乙醇（BCtE）。通过综合技术经济分析（TEA）和生命周期评价（LCA）对这些路线的经济和环境绩效进行了比较。TEA结果显示，BSFtE路线的最低销售价格（MSP）为801美元/吨乙烯，与BFtE（1175美元/吨）、BStE（964美元/吨）和BCtE（2072美元/吨）路线相比，具有明显的经济优势。LCA结果表明，BStE路线的全球变暖潜能值（GWP）最低，为- 1.78 kg CO2当量/kg乙烯，其次是BFtE （- 1.59 kg）、BSFtE （- 0.36 kg）和BCtE （+2.73 kg）。总的来说，BSFtE路线提供了经济和环境性能的最佳整体平衡，使其成为化石基乙烯生产最有前途的替代品。

Plant's lignocellulosic components are high-quality precursors for the preparation of biochar activated materials, but the resulting materials usually exhibit poor compressive strength, thereby resulting in limited applicability. In this study, a novel active adsorption material was prepared from low-polysaccharide lignin, clay, and crude oil using the co-pyrolysis method, which not only overcame the limitation of weak compressive strength of traditional adsorption material but also possessed excellent adsorption capacity for heavy metal ions from wastewater. The novel active adsorption material demonstrates both high compressive strength (10.28 MPa) and optimized structural properties, including a micro-void architecture and exceptional specific surface area (594.52 m² g⁻¹). Static adsorption experiments indicate that the adsorption of pollutants in wastewater by the novel active material primarily occurs within the first 90 min of contact with the wastewater. Subsequently, the adsorption process reached equilibrium, achieving a COD removal efficiency of 86.2 % and reducing the residual oil content in the treated water to 43.0 % of the initial value. Simultaneously, it exhibited high affinity for heavy metal ions, with removal efficiencies ranging from 66.3 % to 99.5 % for Cr⁶⁺, Mn²⁺, Cu²⁺, and Zn²⁺ (each at 2.5 mg L⁻¹) at an adsorbent dosage of 0.1 g L⁻¹. The adsorption process of heavy metal ions by this active adsorption material followed the pseudo-second-order adsorption kinetics. Based on physical and chemical structural characterization results, the honeycomb-like physical structure and chemical composition dominated by oxygen-containing functional groups with nitrogen-containing functional groups as a secondary component constitute the primary mechanism enabling this active material to exhibit both outstanding adsorption performance and high compressive strength.

植物的木质纤维素组分是制备生物炭活性材料的优质前体，但所得材料通常表现出较差的抗压强度，从而导致适用性有限。本研究以低多糖木质素、粘土和原油为原料，采用共热解法制备了一种新型活性吸附材料，不仅克服了传统吸附材料抗压强度弱的局限性，而且对废水中的重金属离子具有优异的吸附能力。新型活性吸附材料具有较高的抗压强度（10.28 MPa）和优化的结构性能，包括微孔结构和优异的比表面积（594.52 m2 g−1）。静态吸附实验表明，新型活性材料对废水中污染物的吸附主要发生在与废水接触的前90 min内。随后，吸附过程达到平衡，COD去除率达到86.2%，处理水中残余油含量降至初始值的43.0%。同时，对重金属离子表现出较高的亲和力，在吸附剂用量为0.1 g L−1时，对Cr6+、Mn2+、Cu2+和Zn2+（各为2.5 mg L−1）的去除率为66.3% ~ 99.5%。该活性吸附材料对重金属离子的吸附过程符合准二级吸附动力学。理化结构表征结果表明，蜂窝状的物理结构和含氧官能团为主、含氮官能团为辅的化学成分是该活性材料具有优异吸附性能和高抗压强度的主要机理。

This paper reviews recent research on biochar, a material derived from the pyrolysis of biomass, with a focus on its characteristics, production methods, and ecosystem services. It highlights not only the agronomic and environmental benefits of biochar but also incorporates recent advances regarding its role in carbon sequestration, stimulation of microbial biodiversity, and enhancement of soil fertility. The review examines how biochar influences plant growth, germination, nutrient availability, and resilience to abiotic stresses, while improving both the quality and quantity of agricultural yields. The potential of biochar in sustainable agricultural systems and food security is also discussed, particularly through innovations involving enriched biochars and agroecological practices. However, its effectiveness is influenced by factors such as production methods, soil type, and climatic conditions, and challenges remain, including degradation and limited knowledge of its long-term effects. An integrated approach combining agroforestry, crop rotation, enriched biochar, and efficient irrigation could enhance the resilience of agricultural systems to climate change while maximizing ecosystem services.
