Utilization of eggshells: A pilot study testing of toothpaste tablet production

Eggshells are one of the main contributors to waste, especially in the food industry as it is being generated in large quantities, causing numerous problems in the environment. In addition, toothpaste tubes in landfills take up to 500 years to biodegrade. The researchers found a way to lessen this environmental problem in the Philippines wherein is to provide a sustainable solution to these issues with the means of creating toothpaste tablets. A quantitative research design was used for this experimental study to assess the acceptability of the toothpaste tablets. The research was concluded through a microbial test at the Lipa Quality Control Center, consisting of various test parameters. The formulations consisted of a combination of 50% eggshells and 50% toothpaste solution, as well as 75% eggshells with 25% toothpaste solution. Unfortunately, due to the results of microbiological testing, the processed ingredients cannot be deemed suitable. Most of the outcomes exceeded the average values, which is an undesirable outcome. Consequently, the researchers managed to create a final product that, regrettably, was determined to be unsafe based on microbial test results. Nevertheless, the idea of developing toothpaste tablets using food waste holds promise as a sustainable practice and a potential research avenue to explore.
