図1を参照して、一実施形態における情報処理システムの構成の一例を説明する。情報処理システム1は、資源のリサイクルを支援するためのシステムである。情報処理システム1は、例えば、樹脂製品又は樹脂原料など、何らかの製品又は原料に関する情報を記憶管理し、製品にリサイクル品である旨の認証を与える否かの判定、又はリサイクル樹脂が移転(例えば、譲渡)されたか否かの判定を行う。情報処理システム1は、端末装置10a,10b,10c、及びブロックチェーンネットワーク20を備える。端末装置10a,10b,10c、及びブロックチェーンネットワーク20は、ネットワークNを介して相互に通信可能である。図1に示す例において、情報処理システム1は、3つの端末装置を備えるが、端末装置の数は任意に設定され、2つ以下でも4つ以上であってもよい。端末装置10a,10b,10cは、それぞれ同様の構成を有してもよいし、異なる構成を有してもよい。一実施形態において、端末装置10a,10b,10cが互いに区別せずに参照される場合は、総称して端末装置10と称される。
図2を参照して、一実施形態における情報処理システム1に含まれる端末装置10及びノード装置200などの情報処理装置を実現するためのコンピュータ100のハードウェア構成の一例を説明する。なお、それぞれの装置の機能は、複数のコンピュータ100により実現することも可能である。
図3を参照して、資源のリサイクルの一例として、一実施形態における樹脂のリサイクルの概要を説明する。情報処理システム1は、資源のリサイクルを支援し、例えば、資源を循環させるためのプラットフォームとして機能する。

図15を参照して、本実施形態において、リサイクル樹脂の入荷から樹脂製品の認証までの間に情報処理システム2において実行される処理フローの一例を説明する。この処理は、情報処理システム2に含まれる各装置のプロセッサが記憶部に記憶されたコンピュータプログラムを読み込み、実行することにより実現される。なお、この処理における各処理ステップについて、既に詳細を説明しているものについては、ここでは詳細な説明を省略する。
本実施形態における情報処理システム1若しくは2、又は当該システムに含まれる装置を実装するためのプログラムは、光学ディスク、磁気ディスク、半導体メモリなどの各種の記録媒体を通じて、又は通信ネットワークなどを介してダウンロードすることにより、コンピュータにインストール又はロードすることができる。
例えば、ケミカルリサイクルにおける廃プラスチック材から油化されるリサイクルナフサを100%用いた場合、リサイクル比率100%とし、例えばリサイクルナフサ10%、石油ナフサ90%を用いた場合、10%リサイクル比率とする。また、100%リサイクルナフサ又は100%廃リサイクル材の原料から開重合により得られたモノマーは、100%リサイクル率のモノマーとする。なお、100%リサイクル比率のモノマーから重合される樹脂は、100%のリサイクル比率のリサイクル樹脂とする。なお重合時の収率が100%でない場合、例えば、収率60~70%であるとき、ロス分である30~40%を廃棄物として扱う。
