Make your own fuel out of paper.
We have for sale one fuel block press.
This is not something I have done before on the web site, but I think the environmental benefits to using this press mean it deserves a bit of publicity!
The press can make five blocks in one press, you load it up with wet newspaper and then pull the lever down to compress the block mould and the water flushes out of the paper. This leaves a solid block (that is still very wet). You then stack the blocks somewhere dry and preferably in the breeze, and after a few weeks - hey presto! the blocks are dry.
