TL;DR: A literature review of the biogas reforming technologies, emphasizing the types of fuel cells available, the advantages offered by each route and the main problems faced, is presented in this paper.

TL;DR: A literature review on the reforming technologies applied to glycerol, the advantages of each route, and the main problems involved is presented in this article, where the authors present a literature review of catalytic reforming for glycerols.

TL;DR: In this paper, the authors proposed the integration of the electrolysis systems for supply and energy, aiming to reduce production costs and improve the efficiency and durability of the main fuel cells.

TL;DR: In this paper, the authors considered the generation and composition of brewery wastewater, highlighting recent studies concerning the optimization of CH4 production by anaerobic digestion, and described the conditions for production of H2 from various agroindustrial wastewater, indicating the adaptations necessary for application of this process to BW and describing relevant studies reported in the literature.

TL;DR: In this paper, a review of the literature evaluating the scenario and viability of the multi-stage anaerobic digestion process applied to agroindustrial effluents is presented, which suggests that future works should focus on the technologies of new microorganisms and optimization of process parameters, providing maturation and scale-up of the two-stage AD technique.
