While cover crop biomass is typically terminated or used as livestock feed, it can also serve as a feedstock for bioenergy production, offering opportunities for additional revenue. This study evaluated the potential of wild pennycress, CoverCress™, annual ryegrass, cereal rye, and field pea biomass for volatile fatty acids (VFAs) production through arrested anaerobic digestion (AAD). Specifically, the effects of harvest timing on cover crop biomass composition and VFAs yield were examined, given the need for effective utilization and storage of early-harvested biomass. The five cover crops were planted in fall 2023 following soybeans and harvested at three different times in 2024. Batch AAD experiments were conducted with a methanogenesis inhibitor added. Results showed that harvest timing significantly affected biomass yield, composition, and VFAs production. Protein content decreased whereas lignin content increased as the crops matured. Total VFA yields ranged from 0.08 to 0.30 g/g-VS (volatile solids), with acetic, butyric, and propionic acids as the main components. The early-harvested cover crops produced similar or higher VFA yields, indicating that AAD is a suitable technology for these feedstocks. Estimated revenues from the produced VFAs were substantial, demonstrating the potential of winter cover crops as feedstocks for VFAs production.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":487,"journal":{"name":"BioEnergy Research","volume":"19 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2026-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12155-026-11005-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147738614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review discusses the advancement of the currently employed Fischer-Tropsch Synthetic Paraffinic Kerosene (FT-SPK) pathway for SAF production through incorporating catalyst-assisted co-gasification.

The role of different catalysts, such as mineral, transition metal, alkali, and alkaline earth metals, carbon-based, and waste-derived catalysts in producing the desired syngas quality (H<sub>2</sub>/CO: ~2) are critically reviewed. FT synthesis has been elaborated by emphasizing the catalysts and process mechanism with respect to FT-SPK production.

This study presents a comprehensive life cycle assessment of bioethanol production from sugarcane molasses to evaluate its environmental sustainability, energy efficiency, and associated uncertainties. The analysis employs the ReCiPe 2016 and cumulative energy demand methods to quantify midpoint and endpoint environmental impacts along with total energy use across the production chain. A gate-to-gate system boundary was adopted, encompassing molasses preparation, fermentation, distillation, and dehydration processes. Results indicate that electricity and steam generation are the dominant contributors to environmental burdens, particularly influencing global warming, fine particulate matter formation, and human toxicity categories. The total energy requirement was found to be 26.98 MJ per kg of ethanol produced, with fossil energy accounting for 93% of this demand. Despite this, the process demonstrated a slightly positive energy balance, reflected by a net energy ratio of 1.04, confirming marginally favorable energy performance. Uncertainty analysis using Monte Carlo simulation revealed stable results with low variability, indicating model robustness. Human non-carcinogenic toxicity and global warming potential were identified as the impact categories contributing most significantly to the overall uncertainty in the results. Overall, the findings suggest that molasses-based bioethanol is a viable renewable fuel option with potential to reduce fossil energy dependence, provided that efficiency improvements in electricity and steam usage are implemented.
