Globally, 400 billion to 1 trillion coffee cups are consumed annually, generating a significant volume of spent coffee grounds. These grounds, rich in slug-toxic alkaloids, are used in gardening to nurture plants and deter slugs, though not foolproof. The petroleum industry faces environmental challenges, prompting bioremediation solutions using microorganisms and coffee husk, a by-product known to reduce hydrocarbons. While coffee husk poses water pollution risks due to caffeine content, it offers applications like organic soil amendments. The roasting and brewing stages also produce spent coffee grounds, approximately 15 million tons annually, with varied chemical concentrations based on extraction processes.
