In 2018, scientists spread 30 truckloads of coffee pulp on a degraded Costa Rican pasture; two years later, tree canopy exceeded 80%, compared with about 20% in an untreated plot

In a unique trial in Costa Rica, researchers utilised coffee pulp to rejuvenate damaged pastures, leading to fascinating results. The organic by-product significantly enhanced soil fertility, prompting a notable increase in woody plants. Meanwhile, the area’s canopy cover flourished, metamorphosing grassland into an emerging forest. The findings emphasise the potential of agricultural by-products in fostering forest regeneration given the right circumstances.
