Manufacture and Characterization of Wrapping Paper Made from Used Cement Bags with Straw Pulp

Introduction

The paper industry has been a significant contributor to environmental degradation due to the high demand for raw materials and the resulting waste generated during the production process. In recent years, there has been a growing interest in exploring alternative and sustainable raw materials for paper production. One such approach is the use of straw pulp and used cement bag pulp to create a new type of wrapping paper. This study aims to investigate the manufacture and characterization of wrapping paper made from a mixture of straw pulp and used cement bag pulp using the soda process.

Background

The soda process is a traditional method of paper production that involves the use of sodium hydroxide (NaOH) to break down the lignin in plant fibers, resulting in a pulp that can be formed into paper. This process has been widely used in the paper industry due to its simplicity and cost-effectiveness. However, the use of this process has been criticized for its environmental impact, particularly in terms of the high energy consumption and chemical usage required.

In recent years, there has been a growing interest in exploring alternative and sustainable raw materials for paper production. Straw pulp, which is a by-product of agricultural waste, has been identified as a potential raw material for paper production due to its high cellulose content and low lignin content. Used cement bag pulp, on the other hand, is a waste material that is generated during the construction industry and can be recycled into paper products.

Research Methodology

The research methodology used in this study involves the collection of straw pulp and used cement bag pulp, followed by the processing of the pulp using the soda process. The pulp mixture was then formed into paper sheets using a hand-held mold and deckle. The paper sheets were then analyzed for their physical characteristics, including grammatur, mass density, tensile strength, and tearing power.

Results

The results of the study showed that the comparison of pulp mixtures had a significant effect on the characteristics of the paper produced. For a mixture with 0% straw pulp and 100% cement bag pulp, the paper produced had the following characteristics:

Grammatur: 108.13 gr/m²
Mass density: 720.89 kg/m³
Tensile strength: 123.28 x 10⁵ n/m²
Torn strength: 1548.71 x 10⁻³ n

Conversely, in a mixture of 100% straw pulp and 0% pulp cement bag, the paper produced showed the following characteristics:

Grammatur: 100.07 gr/m²
Mass density: 833.89 kg/m³
Tensile strength: 153.09 x 10⁵ n/m²
Torn strength: 2026.93 x 10⁻³ n

Interestingly, a mixture with a ratio of 90% straw pulp and 10% of cement pens gave optimal results, where the resulting paper had:

Grammatur: 114.10 gr/m²
Mass density: 796.05 kg/m³
Tensile strength: 150.47 x 10⁵ n/m²
Torn strength: 2000.24 x 10⁻³ n

Analysis and Explanation

From the results above, it can be concluded that the paper produced from a mixture of straw pulp and used cement pens has good potential in the application of the paper industry. Straw pulp, which is a renewable raw material, makes a positive contribution to the strength and quality of paper. Meanwhile, the use of used cement bag pulp not only helps reduce waste, but also improves the physical properties of paper, especially in terms of density and torn strength.

Considering the importance of sustainability in the industry, this research shows that by utilizing recycled materials, we can not only produce quality paper but also reduce the negative impact on the environment. Further research is expected to explore other variations of mixed compositions and processing techniques to find paper formulas that are more efficient and environmentally friendly.

Conclusion

In conclusion, this study has demonstrated the potential of using straw pulp and used cement bag pulp to create a new type of wrapping paper. The results of the study showed that the comparison of pulp mixtures had a significant effect on the characteristics of the paper produced. The use of straw pulp and used cement bag pulp not only reduces waste but also improves the physical properties of paper, making it a more sustainable option for the paper industry.

Recommendations

Based on the results of this study, the following recommendations are made:

Further research is needed to explore other variations of mixed compositions and processing techniques to find paper formulas that are more efficient and environmentally friendly.
The use of straw pulp and used cement bag pulp should be promoted as a sustainable option for the paper industry.
