Overview of Coffee Waste and Utilization for Biomass Energy Production in Vietnam

Abstract

In this paper, the carbon resources recycling of the overview of coffee waste generation in Vietnam. Since few years, there has been a significant research studies was done in the areas of coffee waste generation areas and also waste water generation from coffee production. The coffee residue (solid) and waste water (liquid) both are caused the underground water contamination and also soil contamination. These residues contain high organic matter and acid content leads to the severe threat to environment. In second stage of coffee production process, the major solid residue was generated. Various solid residues such as spent coffee grounds, defective coffee beans and coffee husks) pose several environmental concerns and specific problems associated with each type of residue. Due to the unlimited usage of coffee, the waste generation is high. At the same time, some researchers have been investigated the spent coffee wastes are the valuable sources for various valuable compounds. Biodiesel or biomass productions from coffee waste residues are the best available utilization method for preventing the landfill problems of coffee waste residues.

Propuesta de economía circular para la gestión de residuos de café en cafeterías de la ciudad de Lima en Perú

“…Por lo tanto, es necesaria una solución alternativa para los grandes volúmenes de SCG (San Martin et al, 2021). El gran volumen de residuos de café generados a nivel mundial, estimado en más de dos millones de toneladas anuales, resalta la importancia de desarrollar estrategias eficaces de gestión de residuos dentro de la industria del café (Thriveni et al, 2017). Frente a ello, se afirma que la problemática de los SCG puede ser superada aplicando conceptos de la economía circular.…”
