Elsen Karstad and Matt Owen, Chardust, were early participants on the stoves
list in about 1996. They made briquettes from charcoal fines at that time.
They now also make   biochar Seedballs with collaboration with the inventor,
Teddy from Cookswell Jikos. http://chardust.com/seedballs/4593306541

The processing dust has been turned into briquettes by Chardust in Nairobi -
several tons a day as I recall.

Back to the future!

 

There are several micro-gasification stoves in Kenya where they have been
used in some areas for a few years. Users like the reduced emissions and
reported 40% fuel savings. A few projects are promoting biochar which is
often combined with manure, a combination recommended by local agricultural
extension folks and endorsed by the national university. I wonder if there
have been similar projects in Ghana. 

 

While the stoves produce small quantities of biochar they have been an
effective way to introduce biochar. For larger quantities, people have been
using fines from charcoal production, at least where the fines are not
rolled with clay into fuel balls. 

 

Thanks

Tom,

Thanks for the reference.  VERY recent publication (the journal date is
February 2018  --- yes 2018).   

This will be useful information for some anticipated TLUD stove work in
Ghana.   I will see if my contact in Ghana knows any of the 6 authors.

Abstract

Many cookstove designs and biochar programs have been implemented in many
countries around the world. These programs have had varied degrees of
success which is generally low. Some were able to achieve all their target
objectives, others achieved a fraction of their target objectives whiles
others achieved different results from their initial targets. The low
success rates have been attributed to disregard for various users'
considerations by the past implementers of such designs and programs. This
study seeks to determine the factors and features that Ghana cookstove users
want to be incorporated in the designs of their cookstove and biochar
programs. The study used a nationwide survey of household cooks. It was
found that about 99% of the respondents will prefer a smokeless cook stove.
The challenges that they will want eliminated from the conventional cooking
systems are ranked from the highest to the lowest as: smoke and heat
(35.80%), difficulty in use (21.8%), cost of cooking systems (6.8%), faulty
parts (3.1%), and fuel availability (2.90%). About 83% of the respondents
have no idea of the use of charcoal as a soil amendment tool (biochar),
which presents an opportunity to educate the communities about the potential
of biochar to improve soil fertility and quality. This paper therefore
recommends that future cookstove designers, researchers and biochar programs
implementers consider elimination of smoke and heat as well as fuel
availability ahead of the other factors considered in the design of
cookstoves.
