Use of by-products generated in the processing of coffee berries: A review

Coffee production plays an essential role in the Brazilian economy, and a large centre is located Minas Gerais. In recent years, there has been increase coffee cultivation, consequently generating wastewater (CW) solid waste (skin, pulp, parchment, dregs) during processing stage. Thus, present review study seeks to characterize these by-products from chain their possible applications agribusiness other sectors towards circular mainly related reuse as fertilizer or energy biomaterial recovery. CW treatment complex given high concentrations of organic matter, phenols, nutrients, especially potassium. Still, its use liquid highly recommended it can crop yield. this regard, should be applied soil according nutritional criteria, with potassium reference chemical element. The potential for contamination reduced by applying biological, physical, along recirculation routes washing/peeling/pulping berries. Moreover, used generation, (as filter material biochar), (in natura composted). Key words: wastewater; fertigation; nutrients; recirculation; agro-industrial waste.
