機械回收

As part of its ChemCyclingTM project, BASF invested €20 million into Quantafuel, a start-up headquartered in Oslo, Norway. Quantafuel is specialized in the pyrolysis of mixed plastic waste and the purification of the resulting oil. BASF feeds the pyrolysis oil from Quatanfuel’s plant in Skive in its production Verbund in Ludwigshafen and further processes it into new chemical products by using a mass balance approach. The products have the same quality as products from fossil raw materials. BASF and Quantafuel are also working closely together to further develop and optimize Quantafuel’s technology.

機械回收推動循環經濟

機械回收是循環經濟的重要組成部分，適用於多種材料類別，例如塑膠、電動車用鋰離子電池或金屬。報廢材料可透過收集、分類、粉碎、熔解等流程處理，轉化為二次原料以供新用途。由回收材料製成的產品將進入新的使用階段，直至下一次報廢管理。

針對塑料廢棄物，若符合生態效益最大化、技術可行性及經濟誘因等條件，機械回收是首選解決方案。化學回收技術將作為機械回收的輔助手段。

但回收範疇不僅限於塑料：巴斯夫同時致力貴金屬及電動車用鋰離子電池的回收利用。更多詳情請見下文。

機械回收塑料

Due to the repeated use and processing of the plastics the polymer chains will be damaged so much that the plastic becomes brittle or yellowed. Additionally, the plastic waste is often made up of a mixture of different plastic types which cannot be separated from each other. Such mixtures of incompatible plastics have a significantly negative impact on quality.At BASF’s research scientists are working on developing additives that can specifically stabilize recycled plastics and improve their properties. This enables plastics to be mechanically recycled multiple times and and material loops can be closed more effectively and more often.Daniel Santoro, lab technician at the Application Center for Plastic Additives in Kaisten (Switzerland), compares the optical properties of a recyceld film with and without a stabilizer package.

用於塑料機械回收的添加劑

作為塑料添加劑的市場領導者，巴斯夫推出機械回收解決方案，有助產業發展。在較為嚴苛的應用市場，機械回收塑料面臨著一大挑戰，即再生材料往往技術性能較差或不穩定。針對回收材料使用過程中面臨的種種問題，我們專門開發了添加劑解決方案，以改善材料性能，滿足不同的應用需求。在許多情況下，合適的添加劑組合有助於還原回收材料的品質，提高後續性能，從而達到接近原生塑料的水平。巴斯夫正在開發此類添加劑，以説明塑膠產業從回收材料中創造更多價值，進而全面提高塑料的可循環性。

機械回收 EPS 包裝廢棄物

將可發泡聚苯乙烯 (EPS) 包裝廢棄物進行機械回收這一概念仍鮮為人知。德國一些中型企業回收乾淨的 EPS 包裝廢棄物，加工成二次產品後回到經濟循環。由此類廢棄物製成的碎片可用作石膏砂漿行業的添加劑、座墊的填充材料、磚塊行業的孔隙形成劑或地坪結構中的隔熱流平劑，而所謂的「聚苯乙烯再造粒」則用於保溫隔熱行業。

多層薄膜結構中聚酰胺的機械回收

巴斯夫歡迎共擠聚乙烯 / 聚酰胺薄膜結構回收性的重新分類。根據《包裝法》第 21 條第 3 款規定，參與回收系統之包裝回收性評估最低標準中，中央包裝註冊機構 (Stiftung Zentrale Stelle Verpackungsregister) 已重新分類聚醯胺的回收性：自 9 月 1 日起，共擠聚乙烯 (PE) / 聚醯胺 (PA) 薄膜結構已被認定為可進行機械回收。
