Biodegradable pots for seedling growth were developed from biocomposites based on different byproducts and solid wastes such as gelatin, corn- and wheat-waste flour, sunflower seed husks and rice husks, yerba mate waste and used paper. Water absorption, solubility, tensile and biodegradation tests were carried out to determine physical and mechanical properties of studied biocomposites. Moreover, a direct test with plants was performed during summer months to evaluate the growth of pepper seedlings (C. baccatum) within the biocontainers. Results showed that gelatin-based biocomposites reached the higher solubility and water absorption. After 24 days, wheat- and corn-waste flour formulations biodegraded 28.5 and 27%, meanwhile, gelatin had the most decomposition rate (62%) and paper-based biocomposites, the least (25%). Gelatin based formulations supported the maximum load in tensile tests, although flexural tests showed that paper-based biocomposites are the most flexible. From the field test it was observed that gelatin biocontainers were almost degraded at the first week and also allowed the greatest plant development, acting as fertilizer, even better than the control plant. On the contrary, plant growth in biocontainers based on wheat- and corn-waste flour as well as paper was impeded since the low level of container decomposition. As a consequence, all formulations prepared have proved biodegradation. Gelatin-based containers could be considered as plantable, while the other ones must be considered as compostable.

用于幼苗生长的可生物降解盆是由基于不同副产品和固体废物（如明胶、玉米和小麦废粉、葵花籽壳和稻壳、马黛茶废物和废纸）的生物复合材料开发的。进行吸水率、溶解度、拉伸和生物降解测试以确定所研究的生物复合材料的物理和机械性能。此外，在夏季月份对植物进行了直接测试，以评估辣椒幼苗（C. baccatum) 在生物容器内。结果表明，明胶基生物复合材料达到了较高的溶解度和吸水率。24 天后，小麦和玉米废料面粉配方的生物降解率分别为 28.5% 和 27%，同时，明胶的分解率最高（62%），纸基生物复合材料的分解率最低（25%）。明胶基配方在拉伸试验中支持最大负荷，但弯曲试验表明纸基生物复合材料是最柔韧的。从田间试验中观察到，明胶生物容器在第一周几乎降解，并且还允许最大的植物发育，充当肥料，甚至比对照植物更好。相反，由于容器分解程度低，基于小麦和玉米废料面粉以及纸张的生物容器中的植物生长受到阻碍。作为结果，所制备的所有制剂均已证明可生物降解。明胶容器可以被认为是可种植的，而其他容器必须被认为是可堆肥的。
