Coffee, a widely consumed product on a global scale, is responsible for a significant amount of waste that poses detrimental effects on the environment when improperly disposed of. This waste also generates greenhouse gas emissions, thereby contributing to the overarching issue of climate change. However, an insightful analysis of the composition of coffee residues reveals its latent beneficial properties, suggesting its potential value in diverse domains. This includes both the use of the solid waste generated from coffee and the extraction of its compounds. In this concise overview, we highlight the chemical composition of coffee residue, drawing from prior research, and shed light on the possible applications that can be pursued, with a particular emphasis on its promising role in the field of biomedical applications.
