Active binchotan charcoal for flasks (between 0.5 and 1 litre)

What is Binchotan charcoal ?
Whether you are a zero-waste enthusiast or simply want to find ways to use less plastic in your daily life, Binchotan charcoal is an environmentally friendly alternative to plastic water bottles.

The charcoal is obtained from branches of Ubamegashi, an oak tree that grow in southern Japan, particularly dense. It is fired in a traditional oven, and the resulting charcoal is known to purify water.

At Chamarrel, we offer you an activated charcoal made in Wakayama, certified non-radioactive and without chemical treatment.

The strong points of Binchotan activated charcoal for gourds
Using activated charcoal in your water bottle allows you to drink pure drinking water in all circumstances. Whether you are going to work or to the gym, for your child on a school trip, etc., the charcoal filters the water from the bottle.

This activated charcoal for water bottles allows you to get rid of your plastic bottles. It is therefore an economical and ecological alternative. One stick of charcoal has a shelf life of about 6 months.

In addition to purifying water, Binchotan charcoal makes it lighter in the mouth. It is therefore suitable for the whole family, including infants.

How to use your Binchotan charcoal stick in your water bottle?
Before handling your charcoal, wash your hands thoroughly. Then run the stick under cold tap water. You can also scrub it with a loofah sponge or a standard vegetable brush.

Boil water and immerse your charcoal in it for about 15 minutes to activate it. Take it out and leave it to dry, ideally on a rack in the sun if the weather is suitable or in the open air.

Only when it is completely dry can you put it in your water bottle to filter the drinking water. Eight hours are necessary for optimal purification, but we recommend leaving it in the water overnight.

You can then remove the zero waste charcoal stick and put it in a second container of up to one litre. This way, you will always have pure water available!

Precautions for use
Do not leave Binchotan charcoal in the same water for more than 48 hours. Only use it in drinking water.

If you do not wish  activated charcoal continuously, it should be left to dry before being stored in a dry place. If you have not kept the original pouch, choose an airtight container (glass jar, storage box, etc.).

Frequently asked questions

How is Binchotan obtained?
The pieces of oak are cut into pieces and cooked at low temperatures for several days. This allows the wood to create micro-cavities in its structure. Then the sticks are subjected to an extreme temperature of 1,000°C to be activated. Finally, they are cooled in a mixture of sand and ash, which is why they can have a whitish colour. Finally, each stick of zero-waste charcoal is hand-washed before being offered for sale.

Is activated charcoal dangerous to health?
Activated charcoal has been used in medicine for many years. Even today, it is administered by poison control centres to absorb toxic products or chemicals in the event of oral poisoning. Our Binchotan charcoal is pure, certified without chemical treatment and is not radioactive either. It is therefore completely harmless.

How can you be sure that the charcoal is genuine?
All our Binchotan charcoal sticks come from Wakayama. The reliability of the product is also assured by the CRIIRAD, an independent laboratory charged by Chamarrel to validate that the imported products respect the environmental norms as regards radioactivity and do not present any danger for health.

On the other hand, our charcoal sticks can have a shape or a size which can vary. This is a guarantee of originality that we fully assume.

If the Binchotan comes from Japan, is it really a zero waste and eco-friendly accessory terms?
Real Binchotan is only produced in Japan. We like its authenticity and it allows us to support Japanese craftsmanship.

Moreover, the ecological impact is very limited since the Ubamegashi oaks used are not chemically treated and are not cut down. Only the branches of 1 to 4 cm in diameter are removed. Finally, we buy activated charcoal sticks loose and sell them loose as well.

BINCHOTAN CHARCOAL

Original Japanese product:

Our Binchotan charcoal comes directly from Japan, from the prefecture of Wakayama, the birthplace of Binchotan.

It is made using the ancient method, in a traditional handmade kiln, with branches of Japanese Ubamegashi (holm oak) whose high density is essential for the quality of traditional Binchotan.

Controlled product:

Our Japanese craftsman is renowned for his expertise. He also has the authorizations to export his binchotan. These authorizations are provided by the Wakayama prefecture and are materialized by the yellow sticker which seals each shipment. This ensures the origin and reliability of the binchotan.

Once the Binchotan has arrived in France, at our request, it is tested by the CRIIRAD, a French association approved under the law of 1901 for the protection of the environment, which conducts studies and analyses in the field of radioactivity. These tests are renewed regularly.

Active support for the craft industry:

We have taken the decision to support handicraft production all the way to Japan.

Our activity supports a family that perpetuates the ancestral know-how that is the manufacture of the real Japanese Binchotan.

This is why Binchotan sticks are not regular but we assume this originality.

Product range:

We offer binchotan in sizes S, M and L (like the clothes) or in bulk by 100g (more economical but not "calibrated").

The "calibrated" sticks are all less than 3.5 cm (or even 3 cm) in diameter and are divided according to their weight (20% tolerance):

 - Flask 0.5 - 1 L: 20 g

 - Carafe 1 L: 25 g

 - Jug 1 - 2 L: 35 g

 - Fountain 2 - 3 L: 50 g

 - Carafe 3 - 5 L: 90 g

Use :

The dosage should be adapted to the quality of your water and your palate.

The Carafe stick is sufficient for a 1 litre carafe. Depending on the quality of your water, it may be necessary to switch to a Pitcher stick or even to add 2 Gourd sticks.

This stick can only be used on water that is already drinkable.

It should be handled with clean hands.

1) Put the stick under water and scrub it with a brush or loofah.

2) Plunge it into boiling water for about ten minutes

3) Take it out and let it dry in the open air

4) Once it is dry, place it in your carafe/bottle/flask (ideally in glass or stainless steel) and fill it with DRINKING water

5) Wait (ideally 8 hours or overnight). 

6) Your water is ready to be enjoyed.

Precautions :

- Always handle the Binchotan with clean hands.

- Do not leave the Binchotan in the same water for more than 48 hours.

- If it is not used continuously, be sure to let it dry and then store it in an airtight container. It should then be brushed, sterilised (10 minutes in boiling water) and left to dry before being used again.

- Brush, sterilise (10 minutes in boiling water) and dry the Binchotan at least once a month (our craftsman recommends weekly).

Depending on how often you use it, the Binchotan is effective for +/- 4 months with average continuous use.

After that it can be crushed and used in the soil to enrich it, dried and used as an odour absorber (air, refrigerator) for example.
