Abstract Energy insecurity is a persistent yet insufficiently examined barrier to sustainable informal entrepreneurship in African cities. In Namibia, informal women entrepreneurs in low-income settlements face limited e...

This article takes an educational perspective on a central limitation in biomass electrochemistry: the impossibility of driving multielectron reactions at the global thermodynamic potential. Standard electrode potentials...

The world needs energy. It is an obvious truth you do not need to prove. The modern world needs the electricity. With advancing civilization and the rate of consumption, and the demand for electricity is growing. At the ...

Abstract Renewable energy in Africa has gained increasing attention as a strategic pathway to achieving sustainable development, energy security, and economic transformation. A structured search of peer-reviewed studies ...

Abstract The research provides a comprehensive overview of the Spanish energy landscape in 2023, emphasizing the achievements and challenges in transitioning to a more sustainable electricity system in line with EU polic...

Avaliou-se o efeito de diferentes níveis de energia digestível na dieta sobre o desempenho de alevinos de tilápia-do-nilo (Oreochromis niloticus). Utilizaram-se 125 alevinos com peso e comprimento iniciais de 0,62&plu...

H2 rich gas produced from Scenedesmus almeriensis biomass residue after lipidic extraction by low temperature catalytic gasification is addressed. The pyrolysis-gasification behavior under different atmospheres (CO2/He, ...

The main objective of the study is to improve energy efficiency of a shell-and-tube jet injection fer-menter (SJT) for aerobic cultivation of microorganisms. The relevance of the work is determined by the biotechnology i...

IntroductionHigh penetration of renewable energy sources increases operational variability and planning uncertainty in smart grids. Transparent prioritization of technologies is required before detailed sizing and dispat...

The global shift towards sustainable bioenergy demands not only improved biomass upgrading methods but also credible validation of their techno-economic and environmental feasibility at an industrial scale. Torrefaction ...

Abstract This study presents a comprehensive thermodynamic, economic, and environmental assessment of a novel biomass-fueled tri-generation system designed to simultaneously produce electricity, hydrogen, and desalinated...

Combining densification with torrefaction can substantially improve fuel properties, including energy content, grindability, and hydrophobicity, enabling torrefied pellets to replace coal in pulverized fuel boilers. This...

In wastewater treatment, ammonium removal is a key step which can be done biologically. One method is by coupling a partial nitritation with the Anammox process. The partial nitritation goal is to convert half of the amm...

Third-generation biomass constitutes a renewable energy source that could substitute fossil fuels. This study evaluated the biomethane potential (BMP) of Ulva sp., Codium sp. and Undaria pinnatifida through anaerobic dig...

Abstract Sustainable batteries necessitate high-performance hard carbon negative electrodes derived from abundant biomass. However, realizing their full potential is significantly limited by the inherent diversity of bio...

This research designs a sustainable composite material using PLA, palm biomass, and ground volcanic stone (VSMGP) to improve mechanical and insulation efficiency for green construction. The raw materials were dried , sie...

Estudos recentes têm relatado o estado pluricarencial da população dos estados da Região Norte do Brasil. Paradoxalmente nessa região encontra-se uma grande biodiversidade da flora com variadas frutas e hortaliças,...

Abstract A dual chamber microbial fuel cells was developed using biomass derived reduced graphene oxide (E-rGO) synthesized from Ensete ventricosum corm waste as an anode material for simultaneous bioelectricity generati...

The current demand for clean and renewable energy has provoked considerable changes in the production system of agroindustrial companies. The generation of bioelectricity through the burning of sugarcane bagasse has cons...

Abstract Accurate prediction of bio-oil yield from pyrolysis of organic solid waste is still the main problem in the field of biomass valorization, mostly because of high variability in the composition and the heterogene...

This study examines the fast pyrolysis of rosehip seed waste (RSW) in a fluidized bed reactor, evaluating its potential for syngas production and effective waste valorization. The fluidization behavior of sand/RSW mixtur...

The aim of this study was to investigate the bioenergy potential of greenhouse vegetable wastes like tomato, pepper, and eggplant wastes individually, in equal-mass binary mixtures, and in equal-mass ternary mixtures und...

Abstract Hydrothermal carbonization (HTC) transforms wet or dry biomass into hydrochar, generating a nutrient-rich process water, hereafter termed HTC-PW, which is often overlooked as waste. This review synthesizes curre...

Agricultural landscapes in the tribal regions of Central India are dominated by smallholder, low-input, and highly diversified farming systems integrating crops, trees, and livestock. However, despite increasing promotio...
