Polymers with low environmental impact are of great interest worldwide to reduce greenhouse gases (CO 2 and CH 4 ) and soil and water contamination. Evaluating the biodegradation process of biopolymeric matrices obtained from different biodegradable biopolymers is a priority. This work evaluated the behavior of a foamed material based on biopolymers under the ISO 14855-2: 2007 standard under simulated natural environmental conditions and its ecotoxic potential of the material residues in the growth of seeds Phaseolus vulgaris. A percentage of biodegradation was obtained in the TPS/PLA samples: 84.7 ± 0.3%; 0% MG: 89.1 ± 0.4%; 2% MG: 82.4 ± 0.4%; 3% MG: 82.0 ± 0.%1; 6% MG: 81.0 ± 0.3%; TPSEG: 66.7 ± 2.4%, and TPSE: 62.9 ± 1.0%; having microcrystalline cellulose as a control sample. CH stretch bands were identified at 728 cm -1 related to PBAT vibration that remained constant in the samples containing PHA, evidencing that this material is not an alternative to elaborate foamed materials to improve their biodegradation. Protein-based samples increase their biodegradation rate, while based samples PHA remain resilient over time due to the blend of the polymer and the presence of PLA (1437.5 cm -1 ). The low or high decomposition of the material in weight loss corroborated this behavior of both blends. Regarding the ecotoxicity of the samples, there was no significant difference.
