Researchers dumped tons of coffee waste into a forest. This is what it looks like now.
30 dump truck loads and two years later, the forest looks totally different.
One of the biggest problems with coffee production is that it generates an incredible amount of waste. Once coffee beans are separated from cherries, about 45% of the entire biomass is discarded.
So for every pound of roasted coffee we enjoy, an equivalent amount of coffee pulp is discarded into massive landfills across the globe. That means that approximately 10 million tons of coffee pulp is discarded into the environment every year.
When disposed of improperly, the waste can cause serious damage soil and water sources.
However, a new study published in the British Ecological Society journal Ecological Solutions and Evidence has found that coffee pulp isn't just a nuisance to be discarded. It can have an incredibly positive impact on regrowing deforested areas of the planet.

In 2018, researchers from ETH-Zurich and the University of Hawaii spread 30 dump trucks worth of coffee pulp over a roughly 100' x 130' area of degraded land in Costa Rica. The experiment took place on a former coffee farm that underwent rapid deforestation in the 1950s.
The coffee pulp was spread three-feet thick over the entire area.
Another plot of land near the coffee pulp dump was left alone to act as a control for the experiment.
"The results were dramatic." Dr. Rebecca Cole, lead author of the study, said. "The area treated with a thick layer of coffee pulp turned into a small forest in only two years while the control plot remained dominated by non-native pasture grasses."
In just two years, the area treated with coffee pulp had an 80% canopy cover, compared to just 20% of the control area. So, the coffee-pulp-treated area grew four times more rapidly. Like a jolt of caffeine, it reinvigorated biological activity in the area.
The canopy was also four times taller than that of the control.
The coffee-treated area also eliminated an invasive species of grass that took over the land and prevented forest succession. Its elimination allowed for other native species to take over and recolonize the area.
"This case study suggests that agricultural by-products can be used to speed up forest recovery on degraded tropical lands. In situations where processing these by-products incurs a cost to agricultural industries, using them for restoration to meet global reforestation objectives can represent a 'win-win' scenario," Dr. Cole said.
If the results are repeatable it's a win-win for coffee drinkers and the environment.
Researchers believe that coffee treatments can be a cost-effective way to reforest degraded land. They may also work to reverse the effects of climate change by supporting the growth of forests across the globe.
The 2016 Paris Agreement made reforestation an important part of the fight against climate change. The agreement incentivizes developing countries to reduce deforestation and forest degradation, promote forest conservation and sustainable management, and enhance forest carbon stocks in developing countries.
"We hope our study is a jumping off point for other researchers and industries to take a look at how they might make their production more efficient by creating links to the global restoration movement," Dr. Cole said.

Original Wonder Woman Lynda Carter becomes a superhero for the LGBTQ+ community
The actress recently defended the character as a gay icon.
Once a superhero, always a superhero.
For many, Lynda Carter is the definitive live action Wonder Woman. The actress first brought the comic book heroine to life in the '70s, and even makes an iconic cameo appearance in the modern-day films starring Gal Gadot. She’s got Wonder Woman action figures made in her likeness, for crying out loud.
All that to say, I think we can feel confident in dubbing Carter a Wonder Woman expert. She’s certainly poured a lot of heart and passion into the role over the years, and fans love her for it.
To kick off Pride Month for 2022, Carter tweeted a variant Wonder Woman comic book cover created by artist Paulina Ganucheau, which was released the previous year. The cover depicts the Amazon warrior smiling while brandishing her signature golden Lasso of Truth in front of a vibrant rainbow backdrop.
The sweet moment was cut rather short after someone commented, in all caps no less, that “Wonder Woman IS NOT A SUPER HERO FOR GAYS.”
In true Wonder Woman fashion, Carter was quick with a defensive comeback.
Carter replied, “You’re right. She’s a superhero for bisexuals!”
She attached a 2016 Polygon article where Greg Rucka, a major writer for the contemporary Wonder Woman comics, confirmed that Diana is, without a doubt, canonically queer. He added that considering the entire island of Themyscira where Diana lives was filled with only other Amazons for centuries upon centuries, “it makes no logical sense otherwise.”
Objectively, even the original conception of Wonder Woman had LGBTQ+ roots. When William Moulton Marston created her in 1941, she was inspired by both his wife Elizabeth and their polyamorous partner Olivia Byrne. Their story was depicted in the 2017 film “Professor Marston and the Wonder Women,” starring Luke Evans, Rebecca Hall and Bella Heathcote.
Carter later posted: 'I didn't write Wonder Woman, but if you want to argue that she is somehow not a queer or trans icon, then you're not paying attention.”
She also shared the the importance of keeping the character a queer icon so that others can be empowered to express themselves authentically. “Every time someone comes up to me and says that WW helped them while they were closeted, it reminds me how special the role is,” she wrote.
She then posted a photo from her Wonder Woman TV show days along with the caption: “Love seeing all the love from LGBTQ+ fans today! Now here’s one I’d like to call the ‘ready to fight your homophobic relatives’ pose. Just kidding. (Or am I)?”
This was followed by encouraging others to support LGBTQ organizations such as Trans Lifeline, the Sylvia Rivera Law Project and PFLAG, which is geared specifically toward parents and families.
You know what they say … not all heroes wear capes. But they do all fight for humanity in their own way. Carter might have retired her magical tiara, but she’s still a queen.
