Developing a Sustainable Tennis Ball: A Comprehensive Analysis of Biodegradable Materials and LCA

The tennis ball industry significantly contributes to environmental waste due to the use of non-biodegradable materials. This escalating issue presents the need for sustainable alternatives in tennis ball manufacturing. This literature review investigates environmentally friendly materials that could replace current tennis ball components. By examining natural rubber alternatives derived from plants such as Hevea brasiliensis, Russian dandelion, and guayule, and evaluating biodegradable polymers like polylactic acid (PLA) and polyhydroxyalkanoates (PHAs), the study assesses their viability as core materials. Additionally, organic textiles like hemp and flax fibers are considered for the felt covering due to their high tensile strength and reduced carbon footprints. In the end, the proposed theoretical sustainable tennis ball had a carbon footprint of 0.027 kg CO₂, compared to the emission of a normal ball, which is 0.58 kg CO₂, significantly lowering the environmental impact. Yet, comprehensive life-cycle assessments are necessary to understand the environmental implications fully. Future research should focus on optimizing these materials to balance performance with minimal ecological impact. Adopting sustainable materials in tennis ball manufacturing presents an interesting challenge. While natural materials can substantially reduce carbon footprints, they introduce complexities regarding resource consumption. Collaborative efforts among researchers and industry stakeholders are needed to drive the shift towards more environmentally friendly practices in the industry.
