This paper investigates current trends, key challenges, and circular design strategies that are shaping the transition toward sustainable interior components. Emphasis is placed on the adoption of natural fiber composites, recycled plastics, bio-based polymers, and emerging alternatives such as mycelium-based and biodegradable materials. The study further explores end-of-life considerations, design-for-disassembly principles, and policy frameworks such as the EU Green Deal and Extended Producer Responsibility. While the shift toward sustainable materials offers clear environmental advantages, challenges remain in terms of cost, scalability, and standardization. Through a synthesis of market projections, industry practices, and innovative case studies, this research highlights how sustainable material strategies can support long-term environmental goals while aligning with functional and aesthetic requirements of automotive interior design.

Bu makale, sürdürülebilir iç mekan bileşenlerine geçişi şekillendiren mevcut eğilimleri, temel zorlukları ve döngüsel tasarım stratejilerini incelemektedir. Doğal elyaf kompozitlerin, geri dönüştürülmüş plastiklerin, biyo-bazlı polimerlerin ve miselyum bazlı ve biyolojik olarak parçalanabilen malzemeler gibi yeni ortaya çıkan alternatiflerin benimsenmesine vurgu yapılmaktadır. Çalışma ayrıca kullanım ömrü sonu hususlarını, sökülebilirlik için tasarım ilkelerini ve AB Yeşil Anlaşma ve Genişletilmiş Üretici Sorumluluğu gibi politika çerçevelerini de incelemektedir. Sürdürülebilir malzemelere geçiş çevresel açıdan net avantajlar sunarken, maliyet, ölçeklenebilirlik ve standardizasyon açısından zorluklar devam etmektedir. Pazar tahminleri, sektör uygulamaları ve yenilikçi vaka çalışmalarının bir sentezi olan bu araştırma, sürdürülebilir malzeme stratejilerinin otomotiv iç tasarımının işlevsel ve estetik gereklilikleriyle uyum sağlarken uzun vadeli çevresel hedefleri nasıl destekleyebileceğini vurgulamaktadır.
