The need for alternative, renewable, and sustainable energy sources, driven by climate change and the detrimental effects of fossil fuel consumption, necessitates innovative solutions. Thus, this study investigates the optimization of ethanol yields from pretreated potato residues, using a co-culture of Saccharomyces cerevisiae and Pichia stipitis. Response Surface Methodology (RSM) was initially…

Agro-industrial wastes such as orange peel waste (OPW) and crude glycerol (CG) can be used in anaerobic digestion (AD) to mitigate environmental impacts while generating methane as a renewable biofuel. Brazil produces significant amounts of these residues, highlighting the need for sustainable management strategies. This study evaluated the performance of single and two-stage anaerobic systems in…

The valorization of saline concentrate and brackish water is a key strategy for the sustainable management of water resources, particularly in semi-arid regions. Cultivating microalgae in these effluents mitigates environmental impacts and enables high-value biomass production, offering potential for the generation of bioproducts and added benefits for regional agricultural systems. This study ai…

This study explored a potential route for valorizing the entire biomass from water hyacinth. Initially, the biomass underwent complete characterization, revealing high contents of ash (35%), extractives (25%), and monosaccharides (41%), with glucose being predominant (21%). Lignin content was low (19%), with a monomeric composition rich in G- and H-units (3.6% and 3.4%, respectively). The biomass…

This study examines the feasibility of utilizing acorn wastes from Montado systems in the Alentejo region of southern Portugal as a sustainable feedstock for bioenergy production through thermal gasification. Approximately 45% of the annual acorn harvest remains unused, representing a locally available biomass resource with significant valorization potential. Acorn waste was characterized by prox…
