A Review on the Applications of Coffee Waste Derived from Primary Processing: Strategies for Revalorization

Coffee is an extremely popular beverage worldwide. To obtain it, the berry must be depulped, fermented, washed, dried, and roasted, producing residues: pulp husk, mucilage, parchment. Recently there has been interest in generating high-value products. In this article, advances valorization process are critically reviewed, including overview of composition residues derived from primary processing, uses food, biocomposite, biofuel production (thermochemical conversion). With increasing coffee projected coming years, urgent need to balance it with appropriate use industrial application wastes by-products, which renewable resources rich carbohydrates, proteins, pectin, bioactive compounds (polyphenols). The applications described above, together those that will undoubtedly developed future, represent promising opportunities take advantage agro-industrial processing Coffea spp. develop more efficient sustainable systems through biorefinery approaches circular economy.
