In this study, the performance of hybrid biomass briquettes produced from carbonized sawdust and guinea corn straw using Cissus populnea as a natural binder was investigated. The briquettes were produced at varying blend ratios (S90G0B10, S75G15B10, S60G30B10, S45G45B10, S30G60B10, S15G75B10, S0G90B10). The produced briquettes were tested for ash content, volatile matter, carbon content, calorific value and performance indicators such as ignition time, burning time, burning rate and boiling time. The results showed that the ash content increased with higher proportions of guinea corn straw whereas the volatile matter decreased across the samples thereby influencing the ignition and combustion behaviour of the briquettes. The result of carbon content showed S45G45B10 composition reached a maximum value of 44.6%. This indicates an optimal balance in biomass blending. Similarly, the calorific value was peaked at 24.5 MJ/Kg for same composition demonstrating enhanced energy potential due to the interaction between the blending materials. The combustion performance analysis showed that briquettes with higher volatile matter ignited more easily when compared with those having higher carbon content. However, those with higher carbon content possessed more stable burning characteristics. The S45G45B10 sample showed superior overall performance (combining high energy output with efficient combustion and reduced boiling time). The study demonstrates the potential use of agricultural residues as sustainable energy sources and the effectiveness of Cissus populnea as an eco-friendly binder in briquette production.

Milk production in tropical smallholder systems is constrained by limited high-quality roughage during the hot–dry season. Sweet sorghum silage is drought-tolerant and may replace corn stover silage. Twelve Holstein–Friesian crossbred cows were assigned to the same commercial concentrate plus either corn stover silage or sweet sorghum silage as the primary roughage source (n = 6 per diet). Intake, apparent digestibility, milk yield and composition, and feed-use efficiency were evaluated on day 15 and 30 and analyzed using linear mixed-effects models with cow as a random effect. Compared with corn stover silage, sweet sorghum silage increased dry matter intake (p < 0.05) and improved the digestibility of fibre fractions, including crude fibre, NDF and ADF (p ≤ 0.003), while crude protein- and nitrogen-free extract digestibility were not different (p > 0.05). Milk yield, 4% fat-corrected milk, energy-corrected milk, and feed-use efficiency indices were unaffected by silage source (p > 0.05). Milk protein concentration was higher with sweet sorghum silage (treatment effect p < 0.05), whereas milk fat and lactose were unchanged. Sweet sorghum silage can therefore replace corn stover silage in tropical dairy diets, improving intake and fibre utilization without compromising milk output.

The global transition towards sustainable energy systems necessitates the exploration of renewable alternatives to fossil fuels. Agricultural waste represents a substantial yet underutilised resource for bioenergy production, with energy pellet manufacturing emerging as a promising pathway for converting these residues into standardised, high-energy-density solid fuels. This comprehensive review examines the current state of knowledge regarding energy pellet production from agricultural waste, encompassing feedstock characteristics, pelletisation technologies, pretreatment methods, quality parameters, environmental implications, and techno-economic considerations. This review was conducted through a comprehensive search of peer-reviewed literature using established academic databases, including Web of Science, Scopus, Google Scholar, and PubMed. Agricultural residues, including cereal straws, corn stover, rice husks, sugarcane bagasse, and various crop processing by-products, demonstrate considerable potential for pellet production when appropriately processed. The review critically analyses the influence of feedstock properties such as moisture content, particle size distribution, and chemical composition on pellet quality attributes including mechanical durability, bulk density, and calorific value. Advanced pretreatment technologies, particularly torrefaction and hydrothermal processing, are evaluated for their capacity to enhance pellet characteristics and combustion performance. Life cycle assessment studies indicate that agricultural waste-derived pellets can achieve substantial greenhouse gas emission reductions compared to fossil fuel alternatives, though the magnitude of these benefits depends significantly on supply chain configurations and processing methodologies. The co-firing of biomass pellets with coal in existing thermal power plants represents a pragmatic near-term strategy for emission mitigation whilst maintaining energy security. Despite promising developments, several challenges persist, including feedstock variability, seasonal availability constraints, logistical complexities, and the need for supportive policy frameworks. This review identifies research gaps and provides recommendations for advancing agricultural waste pelletisation as a viable contributor to global decarbonisation efforts.

As the global population continues to grow exponentially, the demand for renewable energy sources is more critical than ever. Bioethanol, derived from lignocellulosic biomass, has emerged as a promising alternative to fossil fuels. This study focuses on optimizing bioethanol production using a supply chain model that incorporates corn stover, sugarcane bagasse, and miscanthus as feedstocks. To minimize overall supply chain costs, a mixed-integer linear programming (MILP) model is developed, considering key cost factors such as feedstock procurement, bioethanol production, transportation, and facility installation. Traditional optimization methods are replaced with the Social Group Optimization (SGO) algorithm to enhance computational efficiency and solution quality. The results demonstrate that SGO achieves lower total costs with faster convergence, making it an effective optimization approach. Sensitivity analysis reveals that feedstock procurement has the highest impact on total supply chain costs, while production costs show moderate sensitivity, and installation costs have also sensitive effect. These findings emphasize the importance of strategic feedstock sourcing and production planning for economically viable bioethanol supply chains. The proposed SGO-based framework offers a practical solution for industry practitioners seeking cost-effective and sustainable bioethanol production. Future research could explore uncertainty modeling, environmental impact assessments, and hybrid metaheuristic approaches to further enhance sustainable supply chain decision-making.
