Figure 2. — Biodegradation evaluation method by gravimetric measurement of carbon dioxide evolved in laboratory-scale test using Microbial Oxidative Degradation Analyzer (MODA) apparatus (a) in controlled compost at 58 °C based on ISO 14855-2. Additional carbon dioxide trap (Ba(OH)₂ aqueous solution bottle (b)) was used only for the percent modern carbon (pMC) measurements by accelerated mass spectrometry (AMS) of evolved CO₂ from poly(butylene succinate) (PBS) biodegradation.
