Researchers have witnessed incredible results after dumping 30 truckloads of coffee pulp, a waste product of the coffee industry, onto an area of degraded former farmland in Costa Rica. Marking out a control area of a similar size, they were astounded by the change over the next two years.
Dr. Rebecca Cole, lead author of the study—which was published in the British Ecological Society journal Ecological Solutions and Evidence—described the change as “dramatic.”
