The people growing their own toilet paper
Robin GreenfieldOne million trees worldwide are cut down each year to make toilet paper. Is it more sustainable to grow your own?
In Meru, a town in eastern Kenya, a lush, leafy plant sways over the landscape. Benjamin Mutembei, a Meru resident, is growing the Plectranthus barbatus plant – not for food, but to use as toilet paper. He started growing the plant in 1985. “I learned about it from my grandfather and have been using it ever since. It’s soft and has a nice smell,” he says.
Plectranthus barbatus is a leafy plant that can grow up to 2m (6.6ft) tall. Its leaves are roughly the size of an industrial toilet paper square and emit a minty, lemony fragrance. Covered in tiny hairs, the leaves have a soft texture. This plant thrives in warm tropical temperatures and partial sunlight and is widely grown across Africa, where it is sometimes used to demarcate property boundaries.
“This has been an African tissue for a long time, and everyone in my household uses the plant. I only buy modern toilet rolls when the leaves have all been plucked,” Mutembei says.
The Plectranthus barbatus plant has provided Mutembei with a cost-effective alternative to purchasing toilet paper in Kenya. Like many commodities, the price of toilet paper has risen across Africa, largely due to the high cost of imported raw materials, such as wood pulp, which is essential for the production of toilet roll. Raw material costs now make up 75-80% of the final cost of tissue products in Kenya, according to the Kenya Association of Manufacturers.
Toilet paper made from virgin wood pulp currently dominates the global industry. “Typical toilet paper is made of 70-80% short fibre hardwood and 20-30% long fibre hardwood,” says Ronalds Gonzalez, a professor in the Department of Forest Biomaterials at North Carolina State University.
Martin Odhiambo, a herbalist at the National Museum of Kenya who specialises in traditional plants, thinks the solution to the environmental impact of cutting trees for toilet paper may already be here.
“Plectranthus barbatus is the African toilet paper. Many young people nowadays are unaware of this plant, but it has the potential to be an environmentally friendly alternative to toilet paper,” he says.
There is no official data on exactly how many people use the plant as toilet paper in Kenya; however, it is widely grown in various parts of Africa and continues to be used in many rural areas where it is easily accessible, says Odhiambo.
Plectranthus barbatus grows to its full height in 1-2 months from a cutting and the cutting itself costs around 50 Kenyan shillings ($0.37).
“The leaves are similar in size to an industrial toilet paper square, making them suitable for use in modern flush toilets or for composting in latrines,” says Odhiambo.
Visitors from across Kenya attend Odhiambo’s lectures on the uses of Plectranthus barbatus and buy cuttings from his botanical garden at the National Museum of Kenya in Nairobi.
“My class has grown to over 600 participants. People are enthusiastic about learning how to use the plant and often ask for cuttings and seedlings to take back to their towns,” he says.
The potential of the plant is also being explored in other countries.
Robin GreenfieldRobin Greenfield, an environmental activist who runs a non-profit advocating for sustainable living in Florida in the US, has been using the leaves of Plectranthus barbatus for five years.
Greenfield runs a “grow your own toilet paper” initiative and cultivates over 100 Plectranthus barbatus plants at his Florida nursery. He shares cuttings for free or for voluntary donations, encouraging people to grow their own toilet paper. So far, he says he has distributed cuttings to hundreds of people.
“There are many people who associate using the toilet paper plant with poverty,” says Greenfield, though he points out that industrial toilet paper is ultimately made from plants too.
Robin GreenfieldGreenfield says he’s had positive feedback from people who have used the plant. “For anybody who feels a little hesitant to try this plant, I would say to drop your worries about what people think about you. And simply by saying, ‘I’m going to be me, and that might mean wiping my butt with some really soft leaves that I grow,’” he says.
But how realistic is it that this plant might become more widely used?
Large-scale production has not yet been explored. Instead companies such as WEPA, one of Europe’s largest toilet paper manufacturers, are reducing the environmental impact of conventional toilet paper in other ways. WEPA has developed a new method using recycled cardboard to produce toilet paper, which does not involve bleaching the fibres, a spokesperson says.
The toilet paper plant, meanwhile, is expected to have a “minimal” impact on the industry, says a WEPA spokesperson.
One drawback is that wastewater and disposal systems, especially in Europe, aren’t designed to handle this type of paper, as only soluble items can be flushed through the system, the spokesperson says.
Greenfield says that’s where compost toilets come in. “I use a compost toilet. The leaves go back to the earth and produce soil, which can then support food growth. It’s a closed-loop system, and I think using these leaves could lead us to a conversation about the environmental benefits of composting.”
Applequist suggests that growing the plant in a controlled environment, within a designated area, and monitoring its growth to limit expansion into the existing ecosystem could help mitigate environmental risks.
Perhaps the biggest challenge to going mainstream, though, remains public acceptance. But from his plant nursery in Nairobi, Odhiambo remains hopeful.
“I know some people see using leaves as toilet paper as a step backward, but understanding the benefits of this plant, I believe it could become the next green alternative,” says Odhiambo. “I’ve been growing it in my nursery and sharing it with communities across Kenya, and people have been amazed by its convenience. If we keep an open mind and continue promoting this plant, we could eventually mass produce it for widespread use.”

When Theo Baker arrived at Stanford University a few years ago, he joined the student newspaper, following the path of his journalist parents, Peter Baker, a White House correspondent for The New York Times, and Susan Glasser, a writer for The New Yorker.
Through his reporting as a student journalist, he eventually broke a story about manipulated data in Stanford President Marc Tessier-Lavigne’s neuroscience research that helped lead to the university president’s resignation.
Theo Baker’s book, How to Rule the World: An Education in Power at Stanford University was released May 19. In it, Baker describes Stanford as a place where proximity to Silicon Valley gives rise to a parallel system of influence, recruitment and money, with investors looking to identify promising students almost as soon as they arrive on campus.
He told Morning Edition host Steve Inskeep there was “a sort of Stanford inside Stanford,” where elite students are drawn into an “alternate reality” of excess and access to cut corners.
In the interview, he discusses how Stanford is not just a university but also a pipeline where status and power can matter as much as ideas.
We reached out to Stanford University for comment and have not heard back.

Fifteen points in tennis? Nice. Thirty, 40 — even better. Advantage — that sounds good. “Love” — that also must be great, right? Well, not quite.
As the French Open rolls on and Serena Williams has announced her return to the sport, maybe you’ve been paying a little more attention to tennis. The sport’s scoring system is notably distinct, and can sometimes be hard to grasp for newcomers. But even tennis aficionados might not know why, or how, “love” became the unmistakable callout for zero points. For this installment of NPR’s Word of the Week, we’re exploring how a word that signifies trailing behind got such a sweet name.
“Love” comes from the heart — or an egg?
It’s hard to pinpoint when the first tennis ball went over the net. Tennis is a derivative of lots of other sports, such as “jeu de paume,” a handball game played in France, said JT Buzanga, the collections manager at the International Tennis Hall of Fame museum.
But tennis became a patented, official sport in 1874, said Steve Flink, a journalist whose tennis coverage got him inducted into the International Tennis Hall of Fame. It has retained its unique, mysterious scoring system ever since.
“By and large, the original system has held up almost entirely,” Flink said.
The use of “love” goes back to the late 18th century, said Jesse Sheidlower, a lexicographer. But it was used earlier than that in card games such as whist and bridge. Before the term made its way to tennis, the sport favored plain old “nothing,” or “nil,” he said.
Why love in the first place, though? Historians don’t really know for sure, but there are a few theories.
The French could have something to do with it. Some historians believe “love” derives from “l’oeuf,” which means “the egg” in French. Because eggs are shaped like zeros, terms such as “goose egg” and “duck’s egg” have been used in other contexts to mean zero, Sheidlower said.
It’s also possible English speakers mispronounced l’oeuf as “love.” But Sheidlower isn’t convinced that’s the answer.
“It’s the French equivalent of an English expression. But since that expression doesn’t appear in French, the French word wouldn’t have been used,” he said.
To be sure, France has had a lot of influence on tennis culture, Buzanga said. For example, “deuce” or a game tied at 40 points, comes from the French word for “two”: “deux.” But he prefers another prominent theory: that “love” comes from the idiom “for the love of the game.” Even if a player hasn’t scored, it doesn’t matter, because their heart is in it. It’s the theory Sheidlower said is the most plausible, because the idiom was used by the English before tennis was popularized.
Another variation of the “love of the game” theory is that the word could have come from the Dutch “lof,” or “honor” — or the Latin “amare,” meaning “to love,” Flink said.
But if tennis’ “love” doesn’t come from a French word, the theory at least has a French sensibility.
“I think the ‘for the love of the game’ is kind of romantic,” Buzanga said.
“Love” probably isn’t going anywhere
Tennis used to be a sport of leisure. The style of play has changed a lot over the years; players are more athletic and competitive, for instance, Flink said. But the rules of the sport are more steadfast, he said.
“There’s this incredible, enduring respect for tradition in tennis,” he said. “Changes are not made easily.”
There has been one major change in modern history: the tie-break. Matches can go on and on because players have to score two consecutive points to break a deuce, or by two games to break a tied set. But the onset of television meant matches would have to get shorter if the sport wanted to capture a larger audience, Flink said.
Change even came for “love.” An alternative sprouted up in the 1970s, and is still used today: “bagel,” named for its zero shape, Sheidlower said. Novices may say “zero,” and insiders will understand what they mean, but they “will needle them about it,” Flink said.
But “love” still prevails.
“People kind of like it,” Flink said. “It’s different. Why say zero when you can say love?”
