ピレリ、ピラム、シントス、BASFが協力し、廃タイヤを新製品向けリサイクル素材に変換
専門家の視点
廃タイヤを原料に戻す「タイヤtoタイヤ」の欧州共同プロジェクトが、ピレリの調整役で動き出しています。回収された廃タイヤはピレリの独ブラウベルク工場やモータースポーツ活動などから集められ、ピルム社の熱分解処理で回収カーボンブラックと熱分解油に変換されます。回収カーボンブラックは品質を高められてバージン材の一部代替としてピレリの欧州生産に戻り、熱分解油はBASFでブタジエンやスチレンなどの化学品原料に混入され、マスバランス方式でリサイクル由来の属性が付与されます。最終的にシントス社がその原料から合成ゴムを製造し、ピレリが再びタイヤ生産へ投入する循環の構図です。ISCC PLUS認証によりトレーサビリティを確保した点が、説明と実行を結ぶ鍵です。ここで重要なのは、品質と性能を維持しながら再生材を戻すと宣言する一方で、再生材の配合比率やCO2削減効果、商業生産での量産時期といった測定可能な指標が示されていないことです。企業連合の枠組みは実体として動き始めていますが、循環の「質」を評価する基準がまだ公開されていません。

The process draws on end‑of‑life tyres collected across Germany, from some Driver retail outlets and motorsport activities, as well as scrap tyres collected from Pirelli's Breuberg plant. They are processed through an industrial chain designed to maximize their inner value, converting them into secondary raw materials – including synthetic rubber – certified under the ISCC PLUS scheme. This ensures traceability along the value chain and enables the circular materials’ reintroduction into the manufacturing of new Pirelli tyres, maintaining their highest standards of quality and performance. Within this process, Pyrum converts end‑of‑life and scrap tyres through a pyrolysis process — a high-temperature thermal decomposition of materials in the absence of oxygen — into two valuable secondary raw materials: recovered carbon black (rCB) and tyre pyrolysis oil (TPO). The recovered carbon black is upgraded in quality and directly reintroduced into Pirelli’s European production, partially replacing virgin carbon black. At the same time, the TPO is supplied to BASF, where it is co-fed with fossil-based feedstock into the production process of chemical products such as butadiene and styrene. A mass balance approach enables attributing the recycled content to the ISCC PLUS-certified Ccycled® products. These circular materials are then used by Synthos to produce ISCC PLUS‑certified synthetic rubber for high-performance tire applications, which Pirelli reintroduces into its production processes, closin
