NeutreStone is a green innovation based on the concept of environmental sustainability, transforming organic coffee waste into an eco-friendly solid air deodorizing product. By combining spent coffee grounds with tapioca starch as a natural binding agent through the gelatinization process, this low-cost product functions through a slow-release mechanism, enabled by its microporous structure that effectively absorbs musty odors in enclosed spaces. In addition to serving as a natural aromatherapy air freshener to address odor-related issues, the caffeine naturally present in NeutreStone also acts as a natural insect repellent against pests such as ants. This makes it an innovative, effective, dual-function solution that is 100% biodegradable.
