Abstract

世界で 4 億 t 以上が生産されている。感染症が蔓延する世界において,清潔な水や医療品を途上国や貧困な 地域の人々に届けるため, 安価で軽いプラスチックの担う役割は大きい。一方, 不法投棄された廃プラスチッ クの一部は海洋に流出し,海洋生態系に深刻なダメージを与え,人間の健康へも影響を与える可能性が指摘 された。廃プラスチックは,重要な環境問題の一つと見なされるようになった。 廃プラスチックのリサイクルでは,対象物の品質と量を考慮し,マテリアルリサイクル,ケミカルリサイ クル,エネルギー回収から最適な手法を選択することが望ましい。現在,プラスチックは主に化石資源から 製造されているが,将来,再生可能資源が主な原料となる。新たに市場に投入される貴重な有機資源を最小 化するため,廃プラスチックの循環利用を促進すべきである。SDGs が目指す世界では,価格や品質だけで なく,環境保全および生物多様性や人権への配慮などの社会倫理性が求められている。 Abstract: Due to superior proper ty as a material, production of plastic has expanded dramatically since the second half of the 20th centur y, and it being manufactured worldwide more than 400 million tons. In a world where infectious diseases are rampant, inexpensive and lightweight plastics can play an impor tant role in bringing clean water and medical supplies to people in developing countries and poor communities. On the other hand, some illegally dumped waste plastic has been spilled into the ocean, causing serious damage to marine ecosystems, and potentially af fecting human health. Waste plastics have come to be one of the key environmental issues. For the recycling of waste plastics, it is desirable to select the most appropriate method from mechanical recycling, feedstock recycling, and energy recover y, taking into account the quality and quantity of the object. At present, plastics are mainly manufactured from fossil resources, but in the future, renewable resources will be the main raw material. To minimize the amount of precious organic resources introduced into the market, recycling of waste plastics should be promoted. In the world the SDGs aiming, good price and high quality are not enough, but also environmental protection, and ethics considering for biodiversity or human right are impor tant.
