Making Porous Ceramics from Pulp Solid Waste with Kaolin Additives as Exhaust Gas Filters: A Sustainable Solution to Air Pollution

Introduction

Air pollution has become a significant concern in recent years, with motor vehicle exhaust gas being a major contributor to this problem. The impact on human health is becoming increasingly serious, and it is essential to find alternatives that can help overcome these issues. This study aims to explore the potential of making porous ceramics from pulp solid waste, combined with kaolin additives, as exhaust gas filters. The goal is to create a sustainable solution that not only reduces air pollution but also provides a valuable alternative to traditional waste management practices.

Background

Pulp solid waste, such as grit, dregs, and biosludge, is a common byproduct of the pulp industry. If not managed properly, this waste can pollute the environment and contribute to air pollution. Kaolin, a type of clay, is a common additive used in ceramic production. By combining pulp solid waste with kaolin additives, it is possible to create a porous ceramic that can be used as an exhaust gas filter.

Methodology

The study involved collecting pulp solid waste from PT. Toba Pulp Lestari, Tbk, and kaolin additives from Bandar Pulau Village, Asahan, North Sumatra Province. The waste was then processed and combined with kaolin additives to create a porous ceramic. The ceramic was then tested for its physical and mechanical properties, including mass shrinkage, burnt shrinkage, ceramic density, porosity, compressive strength, and tensile strength.

Results

The test results showed that the porous ceramic was able to reduce the pollution produced by gasoline gas exhaust gas (C6H12) with a very impressive absorption rate. The absorption rate for carbon monoxide (CO) was 36.21 - 97.14%, for carbon dioxide (CO2) was 25.64 - 95.97%, and for hydrocarbons (HC) was 36.47 - 87.87%. The physical and mechanical characteristics of the ceramic showed that it had a mass shrinkage range of 17.77 - 32.10%, a burnt shrinkage range of 1.97 - 4.07%, a ceramic density range of 1.14 - 1.20%, a porosity range of 27.96 - 54.27%, a compressive strength range of 0.98-69.58 MPa, a tensile strength range of 1.49 x 10^-2-4.05 x 10^-2 MPa, and a level of violence range of 87-127 MPa.

Discussion

The results of this study show that the porous ceramic made from pulp solid waste and kaolin additives is a promising solution to air pollution. The ceramic's ability to absorb CO, CO2, and HC gases makes it an effective exhaust gas filter. The physical and mechanical characteristics of the ceramic also make it suitable for wider applications, both in industry and daily use.

Additional Analysis and Explanation

This porous ceramic offers innovative solutions to overcome worse air pollution. By utilizing solid waste from the pulp industry, this research not only provides alternatives in waste treatment, but also offers large environmental benefits through reducing harmful gas emissions.

Potential of Sustainability

The use of pulp solid waste as a raw material for porous ceramics has the potential in the context of sustainability. Industrial pulp often leaves residues that pollute the environment if not managed properly. By converting this waste into useful products such as gas filters, we not only reduce the volume of waste, but also distract to the search for environmentally friendly material solutions.

Effectiveness of Gas Filter

The test results showed the capability of the high CO, CO2, and HC gas filtering showed that this porous ceramic was very effective in filtering harmful substances produced by motorized vehicles. This is an important step in reducing the negative impact of air pollution on human health.

Physical and Mechanical Characteristics

The physical and mechanical characteristics obtained show that this ceramic is not only effective in the filtering function, but also has good mechanical properties. Adequate density and compressive strength makes this product suitable for wider applications, both in industry and daily use.

Conclusion

With this research, it is expected to open a way for further research on the use of alternative materials in creating efficient environmentally friendly products. Making porous ceramics from pulp solid waste with kaolin additives is not only potential as a solution to the problem of air pollution, but also as a first step towards better and more sustainable waste management. This kind of effort is important to encourage awareness of the importance of protecting the environment for our health and future generations.

Recommendations

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

Further research should be conducted to improve the physical and mechanical properties of the porous ceramic.
The use of pulp solid waste as a raw material for porous ceramics should be explored in other industries, such as construction and automotive.
