The snail industry has experienced rapid growth, and this has led to economic benefits, but it has also led to a large amount of waste from the snail shells, which is a major environmental concern. The waste is normally disposed of in landfills or water bodies, causing pollution and resource wastage. This paper demonstrates how the waste from snail shells can be turned from an environmental concern to an economic benefit. The waste from snail shells is a rich source of calcium-based materials, and this makes it feasible to recycle the waste into valuable materials that can be utilized in various ways. The recycling of the waste has proved successful in agriculture, where it has been used to improve soil quality, as a supplement in animal and fish foods as a calcium source, and in water treatment, where it has been used to remove toxic metal pollutants. Apart from environmental uses, the waste from snail shells can be utilized in the construction industry and in the health and medical field, specifically in bone and dental works. This recycling technique of the waste from snail shells encourages sustainability, prevents pollution, and ensures that waste is turned to wealth through the circular economy approach.
