Rubber Sheet Made from a Mixture of Used Tire Powder and Natural Rubber: A Sustainable Alternative for Sports Shoe Soles

Introduction

The world is facing a significant challenge in terms of waste management and sustainability. The increasing amount of waste generated by human activities has led to environmental degradation and pollution. In this context, the use of recycled materials in various industries has become a crucial aspect of sustainable development. One such industry is the shoe manufacturing sector, where the use of used tire powder as a filler in making sports shoe soles has gained significant attention in recent years. This article discusses the production of rubber sheets from a mixture of used tire powder and natural rubber, which meets the technical specifications of shoe soles based on the Indonesian National Standard (SNI).

The Process of Making Used Tire Powder

The process of making used tire powder involves several stages, including particle size reduction, washing, drying, and filtering. The first stage is to reduce the particle size of the used tire to a size of 60 mesh. This is done to ensure that the powder is uniform in size and can be easily mixed with natural rubber. The next stage is to wash the powder to remove any contaminants, followed by drying to reduce the water content. Finally, the powder is filtered to get a uniform particle size.

The use of a mixture with a composition of used tire powder varies, between 30%, 45%, up to 50% in weight in a rubber mixture. This variation in composition is dependent on the desired properties of the final product, such as durability and elasticity. The use of used tire powder as a filler in making sports shoe soles has several benefits, including reducing waste, increasing the efficiency of natural resources, and creating a more sustainable product.

Volcanization and Technical Nature

After the used tire powder is prepared, the next step is the volcanization process. Volcanization is a process that involves the use of heat and pressure to bind the materials in the mixture, resulting in a strong and elastic product. In this study, the volcanization process was carried out using press printing techniques at 180 ° C for 4.50 minutes. This process aims to produce shoe soles that meet the technical specifications set by SNI 06-1844-1990 ED 1.2.

The results of the study showed that the volcanic soles of natural rubber shoes containing used tire powder with a particle size of 60 mesh meet the technical specifications set by SNI 06-1844-1990 ED 1.2. This indicates that the shoe soles produced are not only sustainable but also have adequate durability for use in sports activities. The use of used tire powder as a filler in making sports shoe soles has several benefits, including reducing waste, increasing the efficiency of natural resources, and creating a more sustainable product.

Added Value and Sustainability

The use of used tire powder in making sports shoe soles has a significant added value. On the one hand, this helps reduce tire waste that is difficult to decompose, and on the other hand, increase the efficiency of the use of natural resources. With the increase in awareness of the importance of sustainability, innovation like this is very necessary to create products that are environmentally friendly and functional.

The use of recycled materials in various industries has become a crucial aspect of sustainable development. The shoe manufacturing sector is one such industry where the use of used tire powder as a filler in making sports shoe soles has gained significant attention in recent years. This study not only provides a deeper understanding of the potential of used tire powder as a filler in the shoe industry but also opens the way for the use of recycled materials in various other applications.

Conclusion

In conclusion, the use of used tire powder as a filler in making sports shoe soles has several benefits, including reducing waste, increasing the efficiency of natural resources, and creating a more sustainable product. The study showed that the volcanic soles of natural rubber shoes containing used tire powder with a particle size of 60 mesh meet the technical specifications set by SNI 06-1844-1990 ED 1.2. This indicates that the shoe soles produced are not only sustainable but also have adequate durability for use in sports activities.
