Binchotan charcoal to filter your tap water, from dream to reality
You purify your tap water with Binchotan, or its Chinese version in bamboo charcoal, sold under many brands.
Before hearing the screams at the back of the room, here is one of my sources of information, there are many others:"Activated carbon": does putting binchotan in water make sense? bywww.lexpress.fr
Do you think Binchotan is organic?
I want to say yes, as much as destroying the Amazonian forests with fire!
Unfortunately, it is oak wood burned at very high temperatures (from 400 to 1200 ° C) for tens of hours (up to 15 days!), Which will release fine particles, CO2, fumes , to then be transported 10,000 km away, and why not coated in aluminized plastic for its conservation.
He will then travel a few thousand kilometers by truck to reach the depot or store before arriving at your place, it is anything but sustainable.
The only organic aspect (apart from it being found in organic stores ...) is that it is easier to recycle than a filter jug filter: in soil, it will decompose.
Ah yes, it is also prettier.

Do you think Binchotan activated charcoal is effective?
No doubt a little bit of a change in taste, but strangely, no independent scientific study proves it, you said weird?
Only the claims of the manufacturers, it is curious for a food product, which should be checked before placing on the market.
Do you think that boiling Binchotan is enough to regenerate it?
Nay, this sterilizes it, but does not regenerate its adsorption capacities, which require an oven at 1200 ° C to unclog its pores and make it “activated” again, it is therefore advisable to change it regularly, but no one knows when, nor how long it takes to purify a volume of water. On the other hand, boiling it, as some advocate once a week, still greatly increases its carbon footprint, the choice is yours.
Do you think Binchotan charcoal is cheap?
Real Japanese Binchotan (for a 1l carafe) costs around € 40 per year, or € 200 every 5 years, certainly cheaper than bottles of mineral water, but far from free. The fake, which you will find almost everywhere, is a little cheaper, but it may be chemically activated with not very cool products, or it may be badly burned and has residual tar or other unpleasant surprise. ...
But how much water can I produce daily?
Some sources say that the water is perfect after 4 hours (but what do they really know, without measurements?), That makes a liter in the morning, and a liter in the afternoon, possibly a liter more if you think about filling the carafe in the evening, this can be limited for a family, except to have two carafes. So much wasted space and manipulation.
