Why use toilet paper? No need to flush our forests

This post now on the syndicated BasilandSpice and on Google News.

We're facing mass wildlife extinctions this century. One big reason: the human population explosion and resulting habitat loss.

You might be surprised to learn how our personal hygiene choices affect wildlife-habitat loss. I was.

Americans flush 54 million trees per year. We're #1!
According to the WWF, almost 270,000 trees are either dumped in landfills or flushed every single day.  About 10% of that total is toilet paper.  Since Americans lead the pack in resource consumption, it's no surprise that we also use more toilet paper than anyone else.  In 2005, North American consumption of toilet paper was 23 kg per capita - 6 times more than the world average of 3.8 kg per capita. Africa had the lowest use in 2005, at 0.4 kg per capita.

Trees of the Amazon, Southeast Asia, the Pacific Northwest and the southeastern US have been targeted by the pulp and timber industry for decades, but now the boreal forests of Russia, Alaska, Canada, and Scandinavia face the growing threat of chainsaws. According to an online magazine World Science, these boreal forests are 1/3 of the world's remaining forested area and 1/3 of the world's stored carbon. Yet the NGO Forest Ethics reports that Canada's old-growth and intact forests are being logged at a rate of 5 acres/minute, 24/7.

China plans to drape itself in tree plantations for paper
North America's rate of toilet paper consumption is stable, but the rate is increasing almost everywhere else, as developing countries aspire to Western ways. Between 1990 and 2003, China's consumption of toilet paper grew by 11%.  China is projected to become the fastest-growing consumer of all paper products, including toilet paper, and will soon lead the world in paper production as well.  Unfortunately most of China's future paper will come from tree plantations. I say unfortunately because tree plantations are generally non-native monocultures, managed with pesticides and consequently devoid of other plants and wildlife. They are biodiversity deserts. China's "Great Green Wall" initiative aims to blanket the country with tree plantations, covering 42% of China's landmass by the year 2050 with tree species that will produce usable fibers.  Many of those trees will be planted in semi-desert areas where they will deplete already-dwindling water supplies.

Solution #1: Post-consumer recycled paper
Toilet paper can easily be made from at least 90% post-consumer recycled paper. Most companies just don't bother to do it, apparently. Kimberley-Clark is the largest tissue manufacturer in the world. Their products are sold in 150 countries and their tissue is used by almost 20% of the world's population every day.  With so large a market, KC could save a great many forest habitats by making their products with recycled paper. Yet, according to Noelle Robbins' excellent research for Worldwatch, Kimberley-Clark claims there is no advantage to using recycled paper. And so their tissue is made from virgin wood fibers. KC is not alone. There's little effort among toilet paper companies to change consumer preferences to more forest-friendly products.

Still, consumers can buy toilet paper made from recycled paper.Marcal makes tissue from recycled office paper, magazines and paper from residential recycle bins.  Tim Spring, CEO of Marcal, says "Sixty percent of all paper ends up in landfills....We throw away enough paper to make toilet paper for a lifetime."  According to Marcal's website, the company has saved 22 million trees since 2000 by using recycled paper.

My local supermarket does not carry Marcal.  They do however carry toilet tissue called "Green Forest" manufactured by Planet Inc., in Victoria, B.C., Canada.  The package says that it is "Minimum 90% post-consumer recycled content."   If you're looking for recycled, the words "post-consumer" are important.  Because manufacturers can and do claim "recycled" when all they've done is trim the uneven ends off their newly manufactured paper and throw the ends back into the vat of wood pulp to be stirred up and rolled flat again. Whereas "post-consumer recycled" (PCR) means that the paper was previously used by a consumer, as office paper or newspaper or whatever.(Toilet paper is the only paper that cannot be recycled, after use, into new paper.)

Great online guide to forest-friendly toilet paper
The Natural Resources Defense Council has a great Shopper's Guide to Home Tissue Products that lists the percent post-consumer-recycled content of 10 to 19 brands in each category of home tissues (toilet paper, paper towels, napkins, facial tissues) and recommends which brands to avoid altogether (Charmin, Cottonelle, Kleenex, Puffs, Bounty, Viva).  Very useful. I was interested to see that Green Forest is actually the best.  The next-best brands of toilet paper listed are 80% PCR.

Solution #2: We learned in Asia that water works better than paper!
During the time I spent recently in two predominately Muslim countries, I was intrigued by the use of water instead of toilet paper throughout these countries. My husband and I were perplexed at first when we found that almost every bathroom we encountered in Malaysia and Indonesia had a bucket of water with a scoop floating on the water. I'm still not sure exactly what that was for, except that it had to do with the hygiene requirements of Islam. We didn't use the buckets, as we're not Muslim.

But most bathrooms also had a hose coming out of the wall next to the toilet, even if the toilet was the kind where you have to squat over a porcelain hole in the floor.

Sometimes the hose had a simple nozzle or a nozzle with a squeeze handle, similar to those many Americans have at the kitchen sink. (Photo at top of post shows nozzle with squeeze handle.)

Bathrooms with hoses generally did not have toilet paper.  It's customary to use the hose and sprayer instead. After a few weeks, we came to prefer the sprayer to paper.  Later, in Tokyo, we saw the ultimate technology in the use of water for personal cleaning - the "Washlet." The toilet itself squirts a stream of aerated clean water on the user (from the underside of the toilet seat at the back) and has a blow-drying system as well!

If only the whole world would use water...
Ecologically, using water is a great solution. According to a quotation in the Worldwatch document cited below, the production of each roll of toilet paper uses 37 gallons (140 liters) of water. The average American uses 57 sheets of toilet paper per day, which requires 3.7 gallons of water just for the manufacturing process. Compare this to 0.03 gallons (0.01 liter) per use of the Japanese Washlet. Various hand-held squirt devices are estimated to use from 0.2 to 0.5 liters per toilet visit.

But even if, hypothetically, the squirting-water methods used the same amount of water as the manufacturing of toilet paper, they don't require the harvesting of trees. And the harvesting of trees at a non-renewable rate is the big problem with our reliance on toilet paper. The overharvesting of trees, or deforestation, is destroying wildlife habitats at an unprecedented rate. We've got to stop it within just the next couple of decades, before it's too late for tigers and orangutans and all the other wild and wonderful critters on this planet.

Squirting devices are hygienic too
Personal washing devices are not only more forest-friendly, they're also promoted as hygienic improvements over the rags, leaves, corn cobs, newspapers, and other items used in many developing countries - methods that often contribute to diarrhea and other health problems associated with poor sanitation. The Worldwatch article cited below describes several water-squirters for bathroom hygiene that can be used in areas without plumbing, such as the Tjebbi - a portable plastic bottle.  It's produced by Tjebok Health Care.

Nozzles please
We're having some plumbing work done on a very old house we bought last spring. We plan to install in both bathrooms a hose and nozzle like the ones so prevalent in Southeast Asia. Maybe we'll stop consumption of home tissues (toilet paper, paper towels, paper napkins, facial tissues) altogether. I like that idea.

Interesting post. Question: how does one stay dry after the hose? In the picture of the restaurant bathroom where a person had to squat, does a person remove clothing before spraying, so as not to return to the table soaking wet?

Very interesting. I need to ask though - is it hard not to get yourself wet? And how hard does the water spray? We have a hose and nozzle that hooks into the toilet water line that we use to clean our baby's cloth diapers. I've tried it on myself, but it sprays a bit too hard.

Also, I wonder if this solution works better on the squat toilets... on an American-style toilet, are you more likely to be more messy because your not as "spread" as you are on a squat toilet? Maybe TMI, but a curiosity nonetheless.

I used the bucket/scoop while I was living in a Thai forest monastery. There was also soap and a faucet outside the "outhouse" for hand washing. One gets used to it after a few weeks. And we only ate with our right hand (for obvious reasons).

Whilst writing this article in a lame attempt to justify the fact that not using paper in Malaysia is actually better for the environment, has everyone completely overlooked the fact that Malaysia continue to cut down the oldest rain forests fin the world for the production of palm oil faster than any other nation bar Indonesia. Therefore, is it not completely ironic, or possibly selective memory to write this article in order to justify a 'forest friendly' solution, whilst overlooking a far larger environmental problem? Lets put things in perspective please. Granted, elements of the article refers to more eco friendly paper solutions however, the comment of 'water works better than paper' is ridiculous. Maintain personal hygiene but at the same time, find a sustainable solution the saving the worlds forests. This article is completely ironic, one sided and selective in its views whilst ignoring the wider economic and environmental issues.

Grow hemp! At a 4:1 harvest ratio compared to trees, it is asinine that it is illegal. All of the industries that would be "affected" by hemp on the market simply need to be re-tooled to process hemp for things like paper, plastic, clothing, fuel, medicine, a building material similar to concrete that is 'carbon negative'. The list is nearly endless. We can have our cake and eat it too, forests remain and tissue for poo! .... Moist, flushable, bio-degradable wipe ones ;)

Actually, it is an age-old habit in Arab/Muslim countries that people use their right hand for eating and their left hand for personal hygiene.

The way to use either the nozzle or the scoop is to gently use your left hand to clean your behind, and then thoroughly wash your hands afterwards. I personally prefer to also use soap if I use the nozzle, however my problem normally is to get my behind dry again. Have not found a really good solution for that.

The power of the spray is not a problem, as it is equipped with a standard tapscrew at the outlet to turn on or off the nozzle, so you can adjust the power of the water jet.

You find this in EVERY toilet in Malaysia. In expensive condominiums, you have a nice, heavy handgrip with angled sprayer that allows and easy control of the water power.

Regarding the washlet from Japan - that one has actually an additional function, namely the heating of the water. Not a convern in Malaysia due to the constant warm temperature, installing a washlet toilet in a Western country (I brought one from Taiwan to Germany) without such a heater function can result in a very shocking experience. The top of the line models, as I have been told, also have a warm air jet to clean your behind, but those are not so easily installed, I guess.
