Integrated Bioethanol Production and Energy Recovery from Sugarcane Waste: Predictive Modeling Under Constraints on the National Sugar Supply

Decarbonizing transport in agro-exporting economies requires tools that couple biofuel production with by-product valorization without displacing food. This study extends a low-data predictive model of sugarcane by-product bioenergy with three ethanol pathways—direct juice fermentation (1G-A), flexible sugar–ethanol pr...

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...

Hydraulic Performance of Variable-Tread Stepped Spillways: Froude Number Reduction and Energy Redistribution at the Stilling-Basin Inlet

Transverse modification of step geometry has been repeatedly proposed as a means of increasing energy dissipation in stepped spillways, with numerically reported gains ranging from 5.6% to 34.7% for labyrinth configurations, in unresolved contradiction with air–water experimental evidence that detects no measurable dif...

Time-Varying Hydraulic Transport and Demographic Trends: Calibrated Modeling of Inflow to a Metropolitan Wastewater Treatment Plant by 2040 (La Chira, Lima, Peru)

Long-term influent flow projection governs the sizing of wastewater treatment plants (WWTPs), yet conventional practice estimates future flows using per capita generation rates and coefficients assumed to remain constant over time, neglecting the fact that, in urbanizing catchments, the fraction of generated wastewater...
