Bounding the Biohydrogen Potential of Organic Market Waste: Fruit-Fraction-Dependent Acidogenesis, Non-Additive Mixture Response, and Overestimation of Avoided-Methane Credits
Dark fermentation of market waste is repeatedly proposed as a decentralized biohydrogen pathway for Latin American cities, and its climate benefit is almost invariably credited using the IPCC Tier-1 term for avoided methane applied to the full diverted mass. This study evaluates how much hydrogen this waste stream can...
