Coffee processing by products valorization an overview of energy and environmental applications

This article examines the valorization of coffee processing by-products in energy and environmental applications. Coffee production generates significant waste, including pulp, husk, and wastewater, which poses environmental challenges if not managed properly. However, these by-products also present opportunities for sustainable utilization. Various methods such as anaerobic digestion, composting, and pyrolysis, have been explored to convert coffee waste into energy sources like biogas and biochar, as well as useful materials like compost. Additionally, using coffee by-products can mitigate environmental impacts by reducing greenhouse gas emissions and minimizing soil and water resource pollution. This review provides insights into the current state of research, challenges, and prospects in the valorization of coffee processing by-products for energy and environmental sustainability.
