Analytical Assessment of Biodegradation Claims in Post-Consumer Polymer–Dextrin Composites: FTIR Identification, Phase Balance Constraints, and Removable Inventory Kinetics

Gravimetric mass loss in polymer–biogenic filler systems is often reported as polymer biodegradation without establishing which phase of the material is lost. This study proposes and applies an analytical framework that combines FTIR identification of the starting material, a pha...

Quantifying the Energy Performance Gap in Low-Pressure Sugarcane Cogeneration: A Seven-Harvest Daily-Resolution Analysis of Simulated Potential Versus Realized Grid Export

Simulation studies of surplus electricity in sugarcane cogeneration almost universally assume stable nominal operation, and the sector literature qualitatively acknowledges that many surplus projects underperform; however, this discrepancy has not been systematically quantified a...
