The study was carried out to integrate physical geometry of compost particle with degradation kinetics to model biological reactions, which revealing additional dynamic approaches. A sphere and its circumscribing cube were used to represent compost particles. An inner sphere, representing anaerobic zone, was introduced to describe variations of substrate volume without sufficient oxygen supply. Degradation...
This study was carried out to develop and compare three models for simulating the moisture content during composting. Model 1 described changes in water content using mass balance, while Model 2 introduced a liquid–gas transferred water term. Model 3 predicted changes in moisture content without complex degradation kinetics. Average deviations for Model 1–3 were 8.909, 7.422 and 5.374kgm−3 while standard...
