Charcoal

Biochar generated as a by-product of combined heat and power gasification is classified as waste, for which the UK does not currently have a safety protocol for use in the open environment. The UEA is working with the Environment Agency to determine environmental tolerance limits, in order to assess potential environmental risks (ex: PAH contamination). My preliminary study aimed to measure any negative plant growth effects by amended soil with high concentrations of biochar under controlled laboratory conditions.

Field Trials;
 I am field testing for the 09 corn season with JMU and consultation  Dr. Hepperly at Rodale Institute.

Ten research priorities were identified at the IBI conference, The following priorities I hope to address:
• 1- Economy research/market research
• 2- plant+soil research depending on biochar
• 5- field trials
• 8- application to soil (depending on agricultural or other
systems/remediation`)

Planting date: June 24th.
Two split plots , which each are split into a 20% (27 tons/Ac) & 5% (7 tons/Ac) application rates,
All chars soaked in tarps for 1 month, all chars were mixed 1:2 by volume with finished poultry litter compost and roto-tilled to 5 inch depth.

Energy Cost of Charcoal
Bryce Nordgren, (Rev) March 26, 2009

Because I really had no idea about how much energy it takes to make
charcoal, I made a table from the specs of the Chinese equipment posted by
gordon eliot. Then I calculated the "Energy Cost" of each component in
(MJ/kg). Finally I aggregated the energy costs from the "suggested
charcoal plants" to get an idea of the energy cost of the entire system.
Note that all of their plants use the new high efficiency coal bar
machine. This should represent a best case scenario: maximum rated
charcoal production at rated power. If you make less charcoal and consume
the same power, the energy cost goes up.

Consider this a first step in understanding the energy efficiency of the
entire process. To complete the analysis, we would have to know the energy
content (MJ/kg) of the produced charcoal. The big question is: can you
power a 30kW generator with the syngas in order to take the small charcoal
plant off the grid?

Charcoal in Container Growing Media

After visiting Richard Haard and Larry Williams in early 2007 I started discussing the use of charcoal with various nursery growers and researchers in the West. A commercial nursery in California became interested in substituting charcoal for vermiculite in a growing media - soilless substrate - for container grown tree seedlings.

The Care for the Environment

The Project

Description of Our Community

In this community there are consumers like us who are interested in environment-friendly products, local business people who are trying to make use of natural resources, and research institutes who are helping make the economy and the environment better. Our project hopes to connect these three kinds of people so that we can know each other better and care more about our environment.

Gardening with Biochar FAQ (Wiki)
Philip Small, May 21, 2008

Welcome to a Gardening with Biochar FAQ!
... a work in progress...

When gardeners add biochar to garden soil, we are, in effect attempting to follow in the footsteps of the originators of Terra Preta. Because we don't know exactly how that process worked, nor how we can best adapt it outside its area of origin, we are left to discover much of this by experimenting with our own gardens and comparing observations within our own communities.

Simple charcoal kiln
Folke Gunther, April 24, 2008

A wonderfully simple method for making charcoal at home or on the allotment.

"http://picasaweb.google.se/folkeg/TheSimplestOfTheSimple

--

There is a wide demand for charcoal kilns to be used by anybody having an allotment or garden sized plot. The idea of making char of surplus biomass instead of firing it is widely spread in Latin America (and Japan?). Burning the pyrolysis gasses instead of emitting them makes the method comparatively safe, although not efficient regarding their potential utilisation of gasses.

I agree that his is a very small scale method, bu imagine 2 billion people having it, making 1 kg char a week for their lots. That would imply about 0.1 Gt annually, or 5% of what would be necessary to sequester for making a change.

Naturally, this is not the method to save the world from entering a tipping point, but it could well be of some help.

Sewage Sludge Charcoal

I am pleased and somewhat surprised to report that raw sewage sludge is a good feedstock for charcoal production. Details are available on the HNEI website below.
