Environmentally Friendly Paper Making From Bacterial Cellulose With The Agitation Method

Environmentally Friendly Paper Making from Bacterial Cellulose with the Agitation Method

Introduction

The conventional paper making process has been a significant contributor to environmental degradation due to the large-scale harvesting of trees. This has led to a growing interest in exploring alternative and sustainable materials for paper production. One such innovative solution is the use of bacterial cellulose, a biodegradable and renewable material produced through the fermentation of bacteria. In this study, we investigated the production of environmentally friendly paper made from bacterial cellulose using the agitation culture method.

Materials and Methods

The production of bacterial cellulose was carried out in a bioreactor using a culture medium consisting of 50 grams of urea, 100 grams of sugar, and 10 liters of young coconut water. The culture medium was rotated at various speeds (100 rpm, 150 rpm, 200 rpm, 250 rpm, and 300 rpm) to increase aeration and equitable nutritional distribution. Additionally, 1 liter of Acetobacter Xylinum bacterial starter and 10 grams of GL3COOH glacial were added to the culture medium to produce bacterial cellulose. The bacterial cellulose produced was then purified using 2.5% NaOH solution, 2.5% NaOCl, and Aquadest.

The paper making process was carried out in an ex-situ by mixing bacterial cellulose with additional materials such as 0.1 gram kaolin, 0.005 grams of tapioca, and 0.02 grams of alum. The mixture was then pressed to form a paper sheet. The characterization of the paper was done through various techniques such as tensile tests, FTIR, XRD, SEM, and TGA.

Results

The results of the study showed that the modulus of Young, which is a measure of material stiffness, increased with the increase in rotation speed in the culture medium. Pure bacterial cellulose had a Young modulus of 22.47 MPa, while paper from bacterial cellulose with a rotation speed of 300 rpm had the highest Young modulus reaching 878,283 MPa. The SEM test revealed that the higher the rotation speed in the bacterial medium, the more the orientation of the morphological orientation of the surface of bacterial cellulose paper.

Discussion

The agitation method in bacterial culture serves to increase aeration and equitable nutritional distribution, resulting in more optimal growth of bacteria. Variations in the speed of the rotation in the culture process not only affect the quantity of cellulose production but also affect the physical quality of the paper produced. The high Young modulus on paper with a rotation speed of 300 rpm shows that the paper has better strength and durability, which is important for paper applications.

The characterization carried out through various techniques such as FTIR and SEM provides a deeper picture of the structure and composition of the paper produced. FTIR helps identify chemical function groups in materials, while SEM provides information about the morphology of paper surface, which is important to understand the mechanical properties of the final product.

Conclusion

This study demonstrates that with the optimization of culture and processing methods, bacterial cellulose can be an environmentally friendly alternative for the paper industry. This is in line with the global trend towards sustainability and reducing the use of non-renewable natural resources. With further research and development, it is hoped that the use of paper-based paper bacteria will be wider and can contribute to environmental preservation.

Future Directions

Future studies can focus on optimizing the culture and processing methods to improve the quality and quantity of bacterial cellulose production. Additionally, the use of bacterial cellulose in various applications such as packaging, textiles, and biomedical materials can be explored. Furthermore, the development of new technologies and equipment for large-scale production of bacterial cellulose can be investigated.
