I'm not current on grain prices but there are often low grade,
semi spoiled, contaminated, bin ends and the such that get looked
at for these purposes. At least I know a greenhouse that burns
grains opportunistically. It is, in a sense, a difficulty for the
ag pellet business having to complete with unpredictable prices
and availability of 'waste' or residue fuels setting the market
floor price, but its hardly a market at this point. <br>
<br>
As far as partial burn economics, on paper it could work. If we
need 50% more fuel for the same heat, at $50/tonne we now spend
$75 for that heat but we have say .2 Tonne of Char. <br>
If it can do the work of $50(untrustworthy number alert) of
potting soil/media then your ahead. It gets a bit tricky here
because we would need to switch from mass to the functional
volume measurement. The devil/angel is in the logistics and
specifics. How much extra capital investment is required? Ag
residue fuel chars may be to high in salts. Do you have the scale
and skill to efficiently produce and handle/size/sort char and mix
all your potting soil? Can you sell the surplus? Can you get
multiple/extra years of use? Does it still have value after use?<br>
Not to mention the cutting edge cache :)<br>

Dear Alex
<div><br>
</div>
<div>I like the idea of finding a use for fuel that doesn't burn
well at all and pyrolysing it to get a good quality burn.

<div>I was discussing pellets v.s. corn with Arend Ten Hove from
the Bay of Quinte area yesterday and it seems corn is or was
cheaper than wood. Something like $110 per ton delivered. Is
that still true? </div>
<div><br>
</div>
<div>Given your need for potting / growth material would you be
able to justify not burning carbon you paid to have
delivered? </div>
<div><br>
</div>
<div>Can you see any break-even prospect? </div>

<div>Thanks </div>
