聚苯乙烯泡沫鱼容器（鱼箱）因其重量轻和隔热性能而非常适合运输鲜鱼。但由于有鱼腥味，鱼盒在使用后被简单地扔掉，在日本仅限于低级回收。为了提高它们的可回收性，我们研究了三甲胺，这会导致鱼一样的气味，以确定它是否是可溶于植物油使用的汉森溶解度参数（HSP）。目前，大岛学院的方法（OCMT），这是用来减少聚苯乙烯泡沫塑料的体积，使用加热植物油，并可以潜在地消除鱼一样的气味。此外，二甲基硫醚，它的原因，在海岸上发现漂流的泡沫聚苯乙烯的海一样的气味，在植物油中的溶解度进行了研究。我们的研究结果得出结论，OCMT可以消除鱼和海一样的气味发现在废聚苯乙烯泡沫塑料，从而提高其回收潜力。
Styrofoam fish containers (fish boxes) are ideal for transporting fresh fish because of their light weight and insulation properties. However, due to fish-like odors, fish boxes are simply thrown out after use and are limited to low-grade recycling in Japan. To improve their recyclability, we investigated trimethylamine, which causes fish-like odor, to ascertain whether it is soluble in vegetable oil using the Hansen solubility parameter (HSP). At present, the Oshima College method (OCMT), which is used to reduce the volume of styrofoam, uses heated vegetable oil and can potentially remove the fish-like odor. In addition, the solubility of dimethyl sulfide, which causes the sea-like smell in styrofoam found drifting on shores, in vegetable oil was investigated. Our results conclude that OCMT can remove the fish- and sea-like odors found in waste styrofoam and thus improve its recycling potential.
