From Invasive Species to Interior Innovation: Feasibility and Market Acceptance of

The aggressive proliferation of invasive aquatic weeds, such as Water Hyacinth (Eichhornia crassipes) and Cattail (Typha spp.), creates a major ecological challenge and generates a substantial organic waste stream with limited current value. The conversion of this abundant lignocellulosic biomass into composite boards for interior finishes, marketed as ‘Lake Board,’ presents a promising pathway toward ecological remediation and circular-economy material innovation. Existing research, however, predominantly focuses on basic mechanical feasibility while overlooking the interior-specific performance metrics—such as surface finishability, machinability, and long-term hygroscopic stability—that are crucial for market adoption by designers and manufacturers. The aim of this research is to evaluate the technical viability of Cattail and Water Hyacinth as raw materials for interior-grade composite boards by analyzing their structural potential and market suitability. A preliminary user survey established a strong 90% positive interest in the Lake Board concept, driven primarily by the material’s potential for lake restoration. Critically, user adoption is conditional on material performance, with Strength and Durability (52.6% priority) and mitigation of Moisture Damage (45% concern) identified as the highest priorities for consumer trust, surpassing the eco-friendly factor alone. This paper validates the need for empirical material testing to meet industry performance standards, which is necessary to translate strong market curiosity into successful commercial adoption.
