StarchAerobic biodegradation60% disintegration rate (CO2 produced) in ~10 days; three-stage TGAs: first degradation ~61–63°C [68], second degradation ~257°C, and maximum disintegration ~280–290°CTampau et al. [46]
Cassava starch/yerba mateDecomposition: vegetal compostDegradation time 6-12 days exhibited changes in tonality and breakdowns materials. Three-stage TGAs: first degradation ~100–150°C [68], second degradation ~180–60°C, and maximum disintegration ~250-350°CJaramillo et al. [49]
Cassava starch/yerba mateAcid and alkaline stability treatmentSwelling capacity: ~1.6 in acid and <1.9-2.2 in alkaline conditionJaramillo et al. [49]
Zein-chitosan-poly(vinyl alcohol)In vitro degradation (enzymatic susceptibility)Amine content: ~0.03 mM Scrine Eq in 30 min; amino acids increase between 60 and 260 min (0.08-0.04 mM Scrine Eq)Giteru et al. [53]
Zein-chitosan-poly(vinyl alcohol)—PEF treated (between 60–70 kJ/kg and 600–620 kJ/kg)In vitro degradation (enzymatic susceptibility)Amine content: ~0.02 mM Scrine Eq in 30 min; amino acids increase between 60 and 260 min (0.02-0.04 mM Scrine Eq). Higher energy yielded higher amino acidsGiteru et al. [53]
Poly(L-lactide)Combination of UV irradiation and enzymatic degradationErosion depth deepens with increasing degradation timeKikkawa et al. [69]
PLAHydrolytic degradationIncreased mass loss as a function of immersion time () at , complete degradation in 288 h; other and 7 yielded no changes in mass lossScaffaro et al. [70]
PLA/CRVHydrolytic degradationFaster kinetics of hydrolytic reactions compared to PLAScaffaro et al. [70]
Poly(vinyl alcohol)/chitosanBuried in the soil for 30 days60% weight loss at 30 daysYu et al. [71]
Poly(vinyl alcohol)/chitosan SiO2Buried in the soil for 30 days~40% weight loss at 30 daysYu et al. [71]

TGA: thermalgravimetric analysis; CRV: carvacrol (CRV) essential oil (2-methyl-5-(1-methylethyl)-phenol); PEF: pulsed electric fields.
