Abstract

This study explores a design management approach to replacing conventional polyurethane (PU) coatings with titanium dioxide (TiO2) coatings activated by plasma ionization in the bamboo furniture industry. PU coatings are widely used for their ease of mixing and application; however, achieving the desired surface durability typically requires multiple layers, leading to higher material consumption, increased worker exposure to hazardous chemicals, and greater environmental harm at the end of the product’s life cycle. As sustainable alternatives gain importance, this research proposes an eco-friendly coating solution using TiO2 activated through atmospheric plasma ionization. A dielectric barrier discharge (DBD) plasma actuator was developed with defined parameters, including electrode configuration, dielectric thickness, and operational voltage and power settings. The device generates plasma at room temperature and atmospheric pressure within a closed system, producing reactive ions that enhance TiO2 adhesion to bamboo surfaces. Experimental findings indicate that this method significantly reduces carbon dioxide emissions and improves eco-efficiency compared to conventional PU coatings, without compromising surface performance. The study details the design and operational setup of the plasma ionization system and evaluates its feasibility as a sustainable coating alternative. Comparative analysis with existing eco-design management literature supports the potential of this method to advance environmentally responsible manufacturing practices in bamboo-based products.
