Toilet paper: 140 million trees, PFAS, and €300 a year — what they don't tell you

140 million trees cut down per year. Between 140 and 180 liters of water per roll. PFAS detected in several European brands. And an annual expense of €150 to €400 per household for a product used for a few seconds and immediately thrown away. This is what toilet paper marketing has never wanted to show you - and why millions of people are changing their habits.

140 to 180 liters of water for your bathroom needs

To manufacture a single standard toilet paper roll, an average of 140 to 180 liters of water is needed. Not for washing it after use - only to produce the paper pulp, power industrial machines, ensure bleaching processes, and cool manufacturing circuits.

For a person who consumes between 100 and 130 rolls per year (French average), this represents between 14,000 and 23,000 liters of water consumed annually for going to the toilet. For a household of 4 people, it exceeds 55,000 liters per year.

In comparison, using a bidet consumes between 0.5 and 1 liter of water per use. The conclusion is clear: it takes up to 300 times more water to produce the equivalent paper than to use a bidet. This industrial water returns to groundwater and rivers laden with chemical residues from manufacturing processes.

140 million trees cut down each year for our toilets

Toilet paper is one of the most resource-intensive everyday consumer products in terms of forest resources. Global production involves the felling of approximately 140 million trees per year. In Europe alone, 15 million trees disappear annually to meet demand.

What distinguishes toilet paper from almost all other paper products is that it can practically not be made from entirely recycled paper. The long fibers necessary for its softness and moisture resistance mostly come from virgin wood - Canadian boreal forests, South American eucalyptus, tropical forests. And unlike a book or printer paper, a roll of toilet paper does not get recycled after use: the fiber is permanently destroyed.

In France, annual consumption exceeds 900 million rolls. A forest equivalent to several tens of thousands of hectares disappears each year for products used for a few seconds and flushed down the drain.

The carbon footprint that is never calculated

From tree felling to supermarket distribution, including pulp production, bleaching, drying, embossing, packaging, and transport, the carbon footprint of toilet paper is estimated at 1.5 to 2.5 kg of CO₂ equivalent per kilogram of paper produced.

For a household of four consuming 400 rolls per year, this represents approximately 150 to 200 kg of CO₂ annually - solely for toilet paper. This is equivalent to a Paris-Barcelona trip by car. Made every year, just for going to the toilet.

In comparison, the manufacturing of a Mizu bidet generates a unique carbon footprint - with no consumables to be produced indefinitely thereafter.

What's really in your toilet paper

Toilet paper is supposed to be one of the purest products available - white, soft, harmless. The chemical reality is considerably more complex, and recent discoveries are concerning.

Chlorine and bleaching agents

The characteristic whiteness of toilet paper is not natural: it results from chlorine or chlorine dioxide treatments. These processes generate organochlorine by-products, including some dioxins with endocrine-disrupting properties, which are found in trace amounts in the finished product. Some manufacturers have switched to elemental chlorine-free (ECF) or totally chlorine-free (TCF) processes, but these mentions remain rare on consumer packaging.

PFAS: eternal pollutants in your toilets

A 2023 study by the University of Florida detected PFAS (per- and polyfluoroalkyl substances) in toilet paper samples from numerous brands - including those marketed in Europe. PFAS are nicknamed "forever chemicals" due to their absolute persistence in the environment and the human body. They are associated with increased risks of cancer, hormonal disruptions, and fertility damage.

Formaldehyde and fragrances

Some "ultra-soft" or scented toilet papers contain wet strength agents based on formaldehyde, classified as a probable human carcinogen (Group 2A) by the International Agency for Research on Cancer. Added fragrances - often mixtures of several tens of aromatic molecules - are among the most common skin allergens.

BPA in recycled paper

Toilet paper made from recycled fibers may contain bisphenol A (BPA), originating from thermal papers (cash register receipts, etc.) incorporated into recycling circuits. BPA is a proven endocrine disruptor, whose use has been banned in food packaging since 2015 in France - but not in toilet paper.

The perineal area is one of the most permeable and well-vascularized areas of the body. It is not the most appropriate place for daily application of products with questionable properties.

Does toilet paper really clean?

The question is worth asking. For any other part of the body - hands, face, teeth - we use water. If you spilled something on your forearm, you wouldn't wipe it with paper and expect to be clean. You would wash yourself.

Perineal physiology is no different. Toilet paper redistributes more than it cleans: it moves fecal matter over a wider area, leaves microscopic residues, and can cause micro-lesions of the anal mucosa - promoting the entry of pathogenic bacteria such as E. coli or Candida albicans.

Clinical data converges: up to 30% of patients suffering from chronic anal irritation see their symptoms significantly improve after adopting water washing. For people suffering from hemorrhoids, anal fissures, perianal dermatitis, or sensitive skin, toilet paper is often a direct cause of worsening - and a water jet is a common medical recommendation.

The true cost of toilet paper: the calculation no one makes

A roll of standard quality toilet paper costs between €0.40 and €0.80. A household of four consumes between 300 and 500 rolls per year - an annual expense of €150 to €400, year after year, for a product immediately thrown away.

Over 10 years: between €1,500 and €4,000. Over an adult life of 50 years: up to €20,000 per person. Exclusively for white rolls flushed down the drain.

The Mizu Essentiel costs less than €70. It connects in 15 minutes, works for years without consumables, and reduces paper consumption by 70 to 90%. The return on investment is counted in a few months.

What are the concrete alternatives to toilet paper?

There isn't just one solution, but several — depending on your setup, budget, and desired comfort level.

The fixed bidet: the most accessible solution

The bidet to be fixed under the toilet seat is currently the solution most quickly adopted in France. It connects to the WC's water inlet via a T-connector supplied in the kit — no plumber, no drilling, no work. Installation in 15 minutes. Complete removal in 5.

The Mizu Essentiel (cold water) and the Mizu Onzen (cold water + hot water) reduce paper consumption by 70 to 90% from the first use. A few sheets are enough for drying — or a small dedicated towel for those more committed to zero paper.

The Japanese washlet: accessible zero-paper

The Mizu Zen and the Mizu Pro replace the existing toilet seat with a complete washing seat: adjustable front and rear jets in pressure and position, heated seat, integrated warm air drying. The result: zero paper, zero compromise on comfort. An electrical outlet with grounding is necessary near the toilet.

The portable bidet: water hygiene everywhere

For travel, trips, or camping, the Mizu Go and the Mizu Go+ ensure the same water hygiene everywhere — manual or rechargeable electric version. Discreet, compact, and extremely effective.

Frequently Asked Questions about Toilet Paper and its Alternatives

Is toilet paper really bad for the environment?

Yes, significantly. Each roll requires between 140 and 180 liters of water to produce, generates 1.5 to 2.5 kg of CO₂ equivalent per kilogram of paper, and contributes to the felling of approximately 140 million trees worldwide annually. France consumes over 900 million rolls per year.

How many liters of water does it take to make a roll of toilet paper?

Between 140 and 180 liters depending on industrial processes and raw materials used. This water is necessary for the stages of paper pulp production, bleaching, embossing, and machinery. This water returns to the environment laden with chemical residues. By comparison, bidet use consumes between 0.5 and 1 liter of water.

Does toilet paper contain dangerous chemicals?

Several categories of concerning substances have been detected in toilet paper samples: PFAS ("forever chemicals"), by-products of chlorine bleaching (dioxins), formaldehyde in some very soft papers, and BPA in papers made from recycled paper. As the perineal area is particularly permeable, this daily exposure warrants attention.

How to reduce toilet paper consumption without changing everything?

The most effective and least invasive solution is a bidet that attaches under the toilet seat. It connects in 15 minutes to the existing water supply, requires no plumber or electricity, and immediately reduces paper consumption by 70 to 90%. The remaining paper is used only for drying.

Is a bidet really more hygienic than toilet paper?

Yes, according to available data. Toilet paper redistributes more than it cleans, leaves microscopic residues, and can cause micro-lesions of the anal mucosa. Clinical studies show that 30% of patients suffering from chronic anal irritation see their symptoms improve after switching to water washing. This is also why water washing is recommended after certain surgical procedures and in situations of sensitive skin.

140 million trees, 55,000 liters of water per household, eternal pollutants applied daily to one of the body's most sensitive areas, and several hundred euros spent each year on a product immediately discarded: toilet paper is one of the few everyday products whose ecological, sanitary, and economic balance accumulates so many arguments against it.

The solution exists. It costs less than €70, takes 15 minutes to install, and lasts for years. All that's missing is the decision.
