“…These bers are fundamental in the plant kingdom, found in trees, herbs and cotton, and are crucial for the structure of plants, providing strength and exibility. The microscopic image obtained from the 250 micrometer sample unequivocally a rms the high quality of the cellulose, coherent with expectations of its presence in natural plant materials [23].…”

This study investigates cellulose extracted from Tibouchina lepidota, a native forest species of Ecuador. It focuses on its potential for industrial use, highlighting its role in the circular economy and carbon footprint reduction. The research explores the use of forest waste as a cellulose source, proposing sustainable alternatives to traditional tree species. The methodology includes botanical identification, sample pretreatment, and cellulose extraction through an alkaline process. The extracted cellulose was characterized using Fourier Transform Infrared (FTIR) spectroscopy and optical microscopy, examining its morphology, structure, and solubility to determine its typology. Results revealed that particle size significantly influences cellulose extraction yield, with smaller particles showing higher efficiency, confirming it as beta-type via solubility tests in alkaline solutions. Microscopic observations indicated a high-quality filamentous structure, with thin, long, and non-oriented filaments. This research demonstrates the viability of Tibouchina lepidota as a sustainable cellulose source, highlighting its potential for industry and contribution to more sustainable and balanced forest management practices, providing a solid foundation for future developments in bioeconomy and composite material industry.
