藻類塑膠回收市場機會、成長促進因素、產業趨勢分析及預測（2025-2034年）

2024 年全球藻類塑膠回收市場價值為 4.857 億美元，預計到 2034 年將以 19.3% 的複合年成長率成長至 29 億美元。

藻類塑膠回收正逐漸成為一種變革性的解決方案，它將藻類轉化為可生物分解的塑膠，為日益嚴重的塑膠垃圾和環境問題提供了一種切實可行的應對之策。不斷成長的監管壓力，包括對一次性塑膠的限制，正促使各國政府和各行業採用更永續的材料。各行各業的公司也在優先考慮碳減排承諾，並將環保原料融入產品線和包裝中，這進一步增強了對藻類替代品的需求。消費者對環保產品的日益青睞也加速了藻類塑膠回收的普及。藻類培養系統的進步，包括高效光生物反應器和自動化收穫技術，不斷提高生質能產量並降低生產成本。監管的推動、企業的永續發展措施以及消費者期望的轉變，共同推動藻類塑膠回收成為全球轉型為低影響材料的重要力量。

微藻領域在2024年創造了1.95億美元的市場規模，反映了其在市場中的強大地位。微藻生長快速、生物化學生產力高，且應用潛力廣泛，涵蓋從可生物分解包裝到農業材料和特定醫療用途等許多領域，使其成為生產藻基塑膠的一種經濟高效且用途廣泛的基礎原料。

到2024年，藻類直接轉化為生物塑膠的市佔率將達到60.5%。此途徑以藻類生質能為主要原料，生產聚羥基脂肪酸酯（PHA）等聚合物。此製程通常包括培養、生質能收集、細胞破碎和聚合物萃取，並利用生物技術基礎設施來簡化生產流程。與廢水處理流程結合，既能降低培養成本，又能帶來額外的環境效益，進而提高經濟可行性。

預計2025年至2034年間，北美藻類塑膠回收市場將以19.4%的複合年成長率成長。消費者日益重視永續的生活方式，以及營養保健品、食品和化妝品產業對環保材料的需求不斷成長，為藻類塑膠的發展創造了有利環境。溶劑系統和回收技術的改進，也使得藻類塑膠的加工成本更低、環境影響更小，與傳統塑膠回收相比，這將促進其在包裝和工業應用領域的更廣泛應用。

參與藻類塑膠回收市場的主要公司包括Algbio、Danimer Scientific、Eranova、Fortum、Gross-Wen Technologies、Kelpi、Nenu2PHAr和Notpla。這些公司採用多種策略來鞏固市場地位並加速商業化進程。許多公司透過最佳化藻類培養系統、改進營養輸送和採用自動化技術來提高生質能產量，從而提升生產效率。此外，這些公司還與包裝製造商、消費品品牌和生物技術合作夥伴建立聯盟，以擴大分銷規模並確保長期供應協議。研發投入仍是重中之重，各公司致力於開發更有效率的萃取技術、先進的聚合物共混物和更優異的生物分解性能。認證項目、生命週期評估和透明的永續發展報告有助於增強公司在監管機構和消費者中的信譽。
