Innovative Sustainable Cellulose Pulp From Lygeum spartum and Recycled Paper: Development and Characterization

Area of Science:

• Materials Science
• Sustainable Materials
• Paper Manufacturing

Background:

• Wood pulp is the traditional source for paper production.
• There is a growing need for sustainable alternatives to wood-based resources.
• Lygeum spartum (Spart) is a plant-based cellulose source with potential for paper production.

Purpose of the Study:

• To develop and characterize paper derived from Lygeum spartum cellulose pulp.
• To evaluate Spart pulp as a sustainable alternative to conventional wood pulp.
• To investigate the effects of additives on the properties of Spart paper.

Main Methods:

• Cellulose microfibers were extracted from Lygeum spartum.
• Paper pulp formulations included virgin Spart cellulose and recycled paper.
• Characterization involved Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and mechanical testing.
• Mechanical barrier properties were assessed through tensile, burst, and tear index measurements.

Main Results:

• Incorporating additives significantly enhanced Spart paper's mechanical barrier properties.
• Tensile, burst, and tear indices increased by 18.57%, 16.50%, and 40%, respectively.
• FTIR confirmed improved fiber-additive interactions, XRD indicated a cellulose I structure, and SEM visualized additive distribution.

Conclusions:

• Lygeum spartum cellulose pulp demonstrates strong potential as a sustainable paper alternative.
• Additives play a crucial role in enhancing the mechanical performance of Spart-based paper.
• This research supports the development of eco-friendly paper products from non-wood sources.
