One of our group members has supplied the following report… “After consulting with a few international experts and a few knowledgeable local people, we took their cautions seriously and decided to start with a small “open burn” rather than a … Continue reading
Here is another well made demonstration video on simple biochar production. This relates to another ‘managed combustion’ system – providing much better environmental outcomes than just burning biomass but still wasteful on the energy front.

We have been getting inquiries for biochar – mainly from gardeners wanting to experiment. As interest grows, demand for larger quantities should follow for commercial application trials. If you are producing biochar in NZ and you are able to share some of your production with gardeners or researchers, then please get in touch.
As the market for biochar matures, we should develop some principles and guidelines for sustainable and safe biochar production, post-treatment and application. The easiest path for now may be to follow IBI, European or other international production / testing guidelines.
We are developing a list of NZ biochar producers who may be able to provide biochar or biochar based products from direct inquires. The producers page will provide contact details and product information.
Kelpie Wilson from www.wilsonbiochar.com has led this initiative… “A quick summary of results of experiments in open burn techniques to minimize smoke and maximize charcoal production. Experiments were conducted by volunteers over a 3 day period, November 15-17, 2013, outside … Continue reading
This biochar workshop delves deep into the many aspects of biochar production and application. Part 1 focuses on practical production techniques using ‘drum within drum’ retort. There may be some advantages for this over the TLUD system (ie, reduced supervision). … Continue reading
The Second burn of the TLUD was an attempt to increase the feedstock value by adding new material in through the secondary air gap during the process. WE started with a half barrel of chips as a way to test … Continue reading
About a year ago I asked an incinerator maker to build me a TLUD based on a design I’d seen on YouTube. Yesterday it worked properly for the first time. The main burner barrel has 50 x 25mm holes in … Continue reading
John McDonald-Wharry, PhD candidate from Waikato U. has kindly provided a link to a newly released paper on his work. He will be presenting related to this at the NZBRC workshop on 4 July with the title “Studying Carbonisation with … Continue reading
The British Biochar Foundation have generously provided video recordings on all presentations from their recent conference in Oxford. The conference was broadcast live as well… lets hope this is a new trend for remote conference attendance. … Continue reading
Cecile Girardin from Oxford Biochar presented results from the 1st year of the Big Biochar Experiment at the recent British Biochar Conference (I will post separately on this conference). I’ve had a dialogue going with Oxford Biochar since early last … Continue reading
