Coffee Pulp and Production Waste Helps Regrow Deforested Areas, 5-Year Study Shows

Coffee pulp and production waste have been shown in a five-year research to encourage regrowth in deforested areas.

Coffee Pulp and Production Waste

The enormous amount of waste produced during coffee production is one of the main issues. A little more than 45% of the total biomass is lost after coffee beans and cherries are separated.

Therefore, a comparable amount of coffee pulp is dumped into huge landfills all over the world for every pound of roasted coffee that is consumed. That means that every year, the ecosystem receives about 10 million tons of coffee pulp.

The garbage can seriously harm soil and water supplies if it is not properly disposed of.

Coffee pulp, however, turns out to be more than simply a waste product, according to a recent study. It may significantly help the planet's deforested areas to restore their forests.

A 100' x 130' section of degraded land in Costa Rica was covered with 30 dump trucks' worth of coffee pulp by researchers from ETH-Zurich and the University of Hawaii in 2018. A former coffee farm that experienced significant deforestation in the 1950s served as the site of the experiment.

Three feet of coffee pulp had been applied over the entire region. To serve as a control for the experiment, a different piece of land close to the coffee pulp dump was kept undeveloped.

Regrowth and Reforestation

The study's principal author, Dr. Rebecca Cole, called the outcomes "dramatic." In contrast to the control plot, which continued to be dominated by non-native grazing grasses, the area treated with a thick covering of coffee pulp transformed into a tiny forest in just two years.

Compared to the control area's 20% canopy cover, the area treated with coffee pulp gained an 80% canopy cover in just two years. Consequently, the region treated with coffee pulp grew four times as quickly. It reactivated cellular activity in the region like a caffeine kick.

Additionally, the canopy was four times taller than the control canopy.

Additionally, an invasive species of grass that had colonized the region and inhibited forest succession was removed in the coffee-treated area. Its eradication made way for the recolonization of the region by other indigenous species.

According to Cole, this case study demonstrates that agricultural by-products can be used to hasten the recovery of tropical forests in degraded areas. Using these by-products for restoration to achieve global forestry goals can constitute a "win-win" situation in cases when processing them costs agricultural companies.

If the results are repeated, both coffee drinkers and the environment will benefit.

Researchers think using coffee treatments to reforest damaged land could be economical.

Battling Climate Change

By encouraging the expansion of forests all over the world, this novel approach might also help to mitigate the effects of climate change.

Reforestation is now a crucial component of the battle against climate change according to the 2016 Paris Agreement. Through the agreement, developing nations are encouraged to lessen deforestation and forest degradation, support forest conservation along with sustainable management, and increase their forest carbon stores.

Cole believes that their work will serve as a springboard for other academics and businesses to consider how they may connect to the global restoration movement to increase the efficiency of their production.
