Abstract Tons of organic waste is produced every day as coffee grounds. The common, concentrated chemical found in these wastes is caffeine which is also a nervous stimulant. Earthworms, especially, Red worms (Eisenia fetida), break down the organic material in wastes through the process of vermicomposting. The effects of caffeine on these Earthworms were studied. Worms were exposed to different concentrations of caffeine and the LC50 was found. It impacted the worm’s composting ability. Different chemical and physical tests were carried on the soil to study its quality. There was an increase in the nutrients of the soil like carbonate and nitrate with increasing concentrations. A significant increase in water holding capacity and humus content can also be viewed from the tests. The study indicated that caffeine with in lethal dose has a positive impact on the worm’s ability to form vermicompost.
