Sustainable Interior Furniture from Recycled Vehicle Tyres with Timber Reinforcement: Mechanical Performance, User Perception, and Economic Viability

ABSTRACT This study investigates the feasibility of producing sustainable interior furniture stools, normal tables, and ottoman coffee tables using recycled vehicle tires reinforced with timber. Employing mechanical tests (static and cyclic loading) and subjective panel evaluations, the research evaluated structural performance, durability, aesthetics, and economic potential. Key results indicated the normal table achieving a maximum load of 450 kg and 50,000 cycles before failure. The normal table exhibited superior mechanical strength and minimal deflection, attributable to its geometry and timber reinforcement, which effectively distributes loads and mitigates fatigue. The ottoman coffee table excelled in aesthetics and comfort, appealing to design-oriented users, whereas the stool offered balanced functionality but with higher deflection and moderate durability. Panel ratings aligned with mechanical outcomes, with the normal table scoring highest in perceived durability (4.7). Timber reinforcement significantly improved prototype performance, surpassing typical household requirements. The findings emphasize timber's enhancement of strength and longevity in recycled materials. Implications include cost-effective production ( $110-245 per normal table) offering 30-50% savings over traditional furniture, supporting circular economy adoption amid rising eco-demand in 2025.
