Processing
Freshly harvested coffee. At the processing plant, the green berries will be sorted out and discarded. Next, the fresh beans will be wet-processed. Water pollution from this process has a big environmental impact. The waste water is acidic and high in natural effluents from the fermentation of the mucilage that envelopes the coffee berry. Fortunately, innovative coffee growers like Oriflama's Walter Adams have developed a process that cuts water use by 95%.
