Waste glycerol from biodiesel production (bioglycerol) can be used for obtaining rigid thermoset materials. In order to gain insights into applicability and final disposition of these renewable materials it is necessary evaluate their long-term behavior under environmental conditions as well as their biodegradability performance. A methyl methacrylate copolymer obtained from bioglycerol was subjected to weathering and biological degradation processes. The first stage of weathering degradation was evaluated using 340-nm light during 216–540 h. The material was affected slightly after 540 h aging, evidencing little chemical changes such as chains scissions as well as the formation of double bonds and hydroxyl groups due photodegradation. In the second stage of biodegradation, the polymer samples were exposed to microbial action of Aspergillus flavus or Aspergillus fumigatus strains. The material showed evidences of fungi colonization and adherence to polymer surface as well as surface damage, after 30 days exposure.

来自生物柴油生产的废甘油（生物甘油）可用于获得硬质热固性材料。为了深入了解这些可再生材料的适用性和最终处置方法，有必要评估其在环境条件下的长期行为以及其生物降解性能。将得自生物甘油的甲基丙烯酸甲酯共​​聚物进行风化和生物降解过程。在216–540小时内使用340 nm光评估了风化降解的第一阶段。该材料在540小时老化后受到轻微影响，几乎没有化学变化，例如链断裂以及由于光降解而形成的双键和羟基。在生物降解的第二阶段，将聚合物样品暴露于黄曲霉或烟曲霉菌株。暴露30天后，该材料显示出真菌定植和粘附在聚合物表面以及表面受损的迹象。
