Bio Char has limited and spotty benefits to the soil. If the soil is
deficient in zinc, adding a carbon plus other materials other than zinc merely
dilutes the zinc and hurts the plant, other nutrients suffer similarly.
Nitrogen is another victim of the use of bio char as the carbon in it depletes
the nitrogen while it is being consumed and converted by the microbes in the
soil.
The low cation exchange of bio char or compost also limits the nutrient
releasing to the plant.
It is unfortunate that low carbon conversion gasifiers or pyrolyzers
may have to dispose of a major energy source, fixed carbon, in the use of bio
char, as it represents some 30% or more of the input energy as fixed carbon to
a conversion system.

Darius,
Good price. Delivered where? At the door of your plant in Indonesia? I can’t
remember where you are.

We can supply biochar for only US$0.25/kg or US$2.5/5gallon

Jeff,
Nothing is that sensible. With retail garden products, and especially on eBay,
weight and value go out the window. It’s whatever the customer (sucker?) will
pay for a package. Garden products are usually sold by volume, not weight.
Take the 5 gallon bucket of biochar that weighs 17 lbs. The blend is 25 lb/ft3
(17 lb/0.67 ft3). If the biochar is about 8 lb/ft3 and the additive, say
compost, is 42 lb/ft3 then that’s a ~50:50 blend by weight. Is it worth $56?
Sip the KoolAid and pay the $56 to support your biochar curiosity. There are
some very good biochar-compost blends that sell for far less.
I like the Biochar “charflakes” at $129/5 gal or $65/2 gal. $192/ft3
(>$5,000 CY) or $240/ft3? (That 5 gal plastic bucket must be worth more than
$2 that I pay.)
I’ll take the 40lb bag for $33 ($0.83/lb). That must be a misprint. The same
supplier wants $1.80/lb for 10 lb and 2.60/lb for 5 lb.
We don’t really know what portion or how much of a market these retail garden
products represent but several sharp marketers are taking advantage of it. If
you are willing to do the packaging and sales and get a lot more than $1/ft3
then you are at the head of the class.
At least eBay makes it easy to find these things on the internet.

Tom,
So, if the charcoal is mixed with compost does some of the compost and water
add to the wieght of the charcaol sold?
Business Model:
Grass compost + moisture + charcoal = X amount of $$$ per pound ????
Here's a 5 gallon bucket of biochar for a cool $129.00:

And more examples:

There is a lot of creative marketing going on with biochar. There is a wide
range of quality. Prices range from $0.35/lb to $2/lb with most selling between
$0.75-$1.00/lb ex plant.
Updraft gasifiers (>10 MWth) have been good sources of char for one biochar
wholesaler/broker. Char is usually conditioned with compost or inoculated
before it reaches the final customer. As nearly as we can tell a few thousand
tons of char was traded in the US in the last year.
