The objective of this research is to provide a new recycling method for one of the most consumed plastics today, since it is used for the manufacture of a wide variety of industrial products, which leads to an environmental problem caused by incorrect handling and final disposal. The dissolution of expanded polystyrene waste was evaluated by using natural esters for its post treatment and recovery. The use of omega-3 as a natural solvent creates an opportunity to take advantage of natural biomass, since it can be obtained from the residues from fishing activities, this being an economic advantage for obtaining raw material and also friendly with the environment. For the development of this research, expanded polystyrene containers were dissolved in omega-3, glyceryl tributyrate, and ethyl butyrate; methanol and isopropanol were used for its recovery. The characterization of the recovered material was carried out with thermogravimetric analysis, differential scanning calorimetry, scanning electron microscopy, infrared spectroscopy and X-ray powder diffraction techniques. The experimental data obtained indicated that the use of these esters is a good alternative for the recycling of expanded polystyrene.

这项研究的目的是为当今消耗量最大的塑料之一提供一种新的回收方法，因为它用于制造各种各样的工业产品，这会导致由于不正确的处理和最终处置而导致的环境问题。通过使用天然酯进行后处理和回收来评估发泡聚苯乙烯废物的溶解性。使用 omega-3 作为天然溶剂创造了利用天然生物质的机会，因为它可以从捕鱼活动的残留物中获得，这对于获取原材料来说是一种经济优势，而且对环境也很友好。为了开展这项研究，将发泡聚苯乙烯容器溶解在 omega-3、三丁酸甘油酯和丁酸乙酯中；甲醇和异丙醇用于回收。采用热重分析、差示扫描量热法、扫描电子显微镜、红外光谱和 X 射线粉末衍射技术对回收材料进行表征。获得的实验数据表明，使用这些酯类是发泡聚苯乙烯回收利用的良好替代品。
