Someone from the states on another forum I am a member was asking about these charcoal sticks http://lifewithoutplastic.com/boutiq…tle-p-664.html
Now I wouldnt buy as they are from Japan and so not sustainable in terms fo carbon foot print and local miles but I wondered if anyone had heard of them or used a siimilar method to ‘purify’ water of metals etc?March 2, 2013 at 1:21 pm #531371
the link isnt working : ( Heres what my other forum friend wrote and the link again to see if it works!
‘water purification system where instead of placing a filter and running the water through it, you place a charcoal stick called “Binchotan Charcoal” in a pitcher of water. The stick absorbs impurities such as chlorine lead etc and imparts calcium, magnesium, potassium…
Does anyone use this method? Have you heard of it? The stick lasts about 6 months and then you can compost it…seems a much less expensive alternative to the carbon filters you place in a pitcher…
Here’s the link to learn more about it: http://lifewithoutplastic.com/boutique/binchotan-charcoal-filter-for-bottle-p-664.htmlMarch 2, 2013 at 1:29 pm #531372
That link didn’t work either, 🙁 and I can’t help with that but I would like to know more about it, how would you know when it’s not doing it’s job? :shrug:March 2, 2013 at 1:35 pm #531373
That’s quite interesting. I wonder if a piece of charcoal from your fire would do the same thing?? From the website
Binchotan Charcoal Filter for Bottle
Binchotan Charcoal Filter for Bottle
Plastic-free water purification – the way it should be. The Japanese have been using Binchotan charcoal for centuries to purify water. No need for the disposable plastic casing typically used to hold charcoal granules as the charcoal stick is a natural absorber of impurities.
One stick of the small size Binchotan charcoal for bottle lasts up to six months, purifying approximately 1 litre / 4 cups of water per day. Just let the stick sit in the water for about 1 hour before using.
Binchotan charcoal is a unique charcoal exclusive to the forests of Wakayama, a province in southern Japan. The branches of holm oak trees are sustainably harvested then slowly fired in traditional kiln ovens over many days. Binchotant charcoal sticks naturally absorb toxins such as chlorine, lead, mercury, cadmium and copper from tap water and impart good minerals such as calcium, potassium, magnesium and phosphates to water.
Care and use: It is recommended that the stick be boiled in a shallow pan of water for 10 minutes every month or so to keep the exterior pores open and make it last longer.
After six months, boil the charcoal stick again. If you don’t see a profusion of bubbles circulating around the charcoal stick when it is returned to the water bottle and water is added, the stick has reached its capacity to absorb toxins. At that point it is ready to be composted in the garden or used as an odor absorber in the fridge.

Binchotan is produced by firing in a sealed kiln at a low temperature for a long period – up to 4 days.
Oxygen in the kiln is reduced in order for the carbonisation to take place. It is then refined at very high temperature – over 950°C – for a short period.
After firing it is removed from the kiln and smothered with sand, ash and soil giving it’s distinctive white appearance.
The result is a highly dense charcoal with a carbon content of approx 93-95%.
The binchotan from the Kishu region is said to have the best binchotan with a carbon content of 96%.
Lump charcoal is generally made in a closed container by burning wood at about 500°C with little oxygen before it’s extinguished and cooled. It has a carbon content of 70-80%, and burns away quickly.
