This study investigates consumer perceptions and the market viability of recycled plastic as a sustainable substitute for wood in interior design. With the rising global demand for eco-friendly materials, recycled plastic offers a promising alternative to traditional wood, potentially reducing deforestation and waste. The study employs a mixed-methods approach, incorporating quantitative surveys to capture consumer attitudes and preferences, as well as qualitative case studies to understand market trends and practical applications. Findings reveal that while consumers appreciate the environmental benefits of recycled plastic, concerns about durability, aesthetic appeal, and cost affect their willingness to adopt it widely. Furthermore, the analysis identifies a positive trend in acceptance among younger, environmentally conscious consumers, indicating a growing market potential. However, successful adoption in interior design requires addressing perceived quality gaps and enhancing product design to compete with traditional materials. The study concludes that recycled plastic, with targeted improvements and strategic marketing, could play a pivotal role in sustainable interior design, contributing significantly to both ecological conservation and market diversification.
