When we last went to Brittany we came across a burnable wood product.
This stuff is very interesting in that it is a type of brick made from waste wood. Stuff that gets chucked on the floor or sent to landfill. This product is made by finely grinding the wood and wood yard waste then passing it through an oven in which 10% of it gets burnt. The remainder is heated to 550C at which point virtually all the water evaporates and the wood is tinder dry. Crucially the lignums melt, so when it is compressed and extruded you are left with a very dry compact block that contains 4 times the heat energy as an equivalent block of kiln dried wood.
Unlike a lot of what you can get in this country, this process does not involve adding any binding agents or glues which would screw up your chimney.
I am very impressed. Out fire was going fine this evening but the student wanted a bath so I added one block of this stuff weighing about 1.5 kg. The living room has gone from 23 - 26 C in about 40 minutes and I cannot open the fire vents as the water in the boiler boils pretty much on the spot.
You have a clean fuel, the bricks don't leave mess on the floor, very easy to control and you can bank the fire then leave it a couple of hours before adding any more fuel. There is virtually no ash as everything gets burnt. Next time I go to Brittany I am bringing more of this stuff back.
More than that, the student is printing leaflets and looking to sell the stuff we bring back. If it works out we are going to look into the costs of getting a plant. We have two sawmills locally we could be on to a financial winner here.

You might well find that there are grants available to help you set up. I think you live in a convergence area which means there's more money available than in other parts of the country. I can send you some places that might have grants via Tia if you're interested.
Grants sound good to me....

The steam lads could use this stuff too. I wouldn't mind burning it in my steam launch, when I stop playing fire engines for a moment and get it working!
