Binchotan, also known as shiro-zumi or white charcoal, is an activated charcoal or carbon made in various regions of Japan. Our Binchotan comes from the Kishu or Tosa regions. It is a traditional material and is widely used in Japan for food preparation, as a smoke-free, long-burning BBQ fuel and Ikebana (Japanese flower arranging).
Other applications include water filtration, humidifying, air filter, radio frequency shielding, electromagnetic wave absorber, bathroom/cupboard/fridge deodorising and personal care products.
This Binchotan is made from 100% Ubame Oak (Quercus phillyraeoides) which is the official tree of Wakayama prefecture, Japan where it is made.
It is made in a kiln by artisans who heat the stacked oak branches to a relatively low temperature (200–400 degC) over a long period and raise the kiln temperature to approx. 1000degC towards the end of the pyrolysis process. The charcoal is then removed and smothered with a moistened mixture of earth, sand and ash. The use of ash to quench the material gives the charcoal a pale grey colour and its name of ‘white’ charcoal.
This process of heating and cooling carbonises the wood structure and creates countless microscopic cavities. It is around 97% pure carbon and has been reported to have a surface area of approx. 270 m2/g (reference: http://pubs.acs.org/doi/abs/10.1021/ie50258a007). It adsorbs or bonds with toxins at a molecular level. It also releases Calcium, Magnesium and Potassium. The Colorado State University produced the following table and graph that can be found at www.kishucharcoal.com/science and details the metals that were reduced in their research.
Following is a care table for keeping track of time for maintaining the charcoal. This is a guide and a conservative guess on the replace date. Compare the smell and taste to tap water to decide if the microscopic pores are full.
Use Start Date |
|
Boil 1 Date = Start Date + 3 weeks |
|
Boil 2 Date = Boil 1 Date + 3 weeks |
|
Boil 3 Date = Boil 2 Date + 3 weeks |
|
Replace Date = Boil 3 Date + 3 weeks |

Hi folks Carol is very happy with the hoe can’t keep her out of the garden. When we get some more spare coin we come have another look round. Cheers Keith….
The bamboo hair brush is amazing.
I no longer get static in my long hair which is great as I was getting some minor electric shocks before, but they have all stopped since using the brush. My hair is shiny and my scalp gets a massage each time which feels wonderful.
Totally recommend this product.
Excellent quality. Easy enough to clean. No problem using in our Pixie. Making up pods is quite simple. We’re still trying to find the right coffee to use. Overall - love it!
Love the fact that you followed through with your promise to get in touch with me when potato seed was back in stock. I’ve received my seed and look forward to planting them out soon.
It is so great to be able to use compostable bin bags. I use the small for my bench bin and the large for bigger amounts. They are easy to use and really good for the environment.
Fantastic that it is made of recycled fabric at an affordable price.
Thank you for the great customer service with a lovely handwritten note and a perfect lid for my broken one. Thank you
This addition to my kitchen sill is perfect.. handy and so lovely micro herbs already !!
well-crafted good looking tool that is well up to pretty strenuous demands. it cuts a wider swathe through the weeds for the effort expended and the light weight allows me to work longer.
a good buy that suits my purposes
It's reasonable price and good quality. I found a great use for my climbing vegetable :)
The elephant garlic has been in the ground about a month or so now. It took a few weeks to emerge but now it is going gang busters. I’m looking forward to being able to taste the harvest.
If you haven't tried this little beauty - you should. Great scrubbing ability, we can thread it thru the handle of the tap and it can air dry. We wash on the top rack of our dishwasher and hang on the clothesline to dry and get UV - lasts forever. Great price. Why wouldn't you try one?
Received 31 May 2022. Placed in veg garden immediately and have not seen the cabbage white butterflies in the garden nor anywhere near it since.
So far so good
Received Tues 31May 2022, planted potatoes the following day. so easy
This seed box is generously sized to fit many seed packets and able to be varied by taking some dividers out, if desired.
It’s an attractive way to keep seeds, and also so nice to have something Australian made and sustainably sourced by the UR team.
Thank you
