Oh Lord Jesus! Forty years ago my father purchased one of those presses that you used torn up soaked newspaper in to squeeze the water out and then store to dry. Waste of time, burned quickly, gave off little heat at all. 

Around the same time I dropped some meat off for an old couple. The freezer was in the garage, and all along the inside wall about 2 feet tall was a wall of those paper bricks. The old chap was so proud with his cost saving he went through the whole process explaining from start to finish. It certainly made an impact on my memory.

I’ve still got one of those presses, somewhere in the garage.

I've often wondered if one of these would work with sawdust(from the chainsaw). I sometimes have four or five bin liners full.

When we first moved to wales, the side annex was a coal store that held about 3 tonnee of coal. It had never been cleaned out, and obviously had a lot of dust. I mean, never cleaned out, easily a tonnee of dust. I specifically remember mum looking like a miner, she used to make bricks using the coal dust and cement in a round press and that was the main fuel for the rayburn for the winter.

Some that know say that yes you can mix the sawdust with the newspaper mache to give longer burning and improve the calorific value.

Thank you for the info gents . It's something that I really fancy having a go at in the future 👍.

Hello, years ago I was looking into a log making machine using straw bales , there are quite a few designs from a small DIY to industrial size where some farms in UK manufacture logs to supplement their incomes, one I looked was a Biomass briquette machine, you can add to the straw, sawdust , wood chips, even a additive that binds straw together

great stuff ! cheers folks..👍

I bought a bag of the blocks and was quite impressed I timed the burn length and they seemed to burn as long as the kiln dried silver birch that I  already had , generally I use the kiln dried stuff as the final heat in my pizza oven which is brought up to heat with homegrown willow. Both the birch and the blocks have zero moisture, pluses for the blocks are 1, cheaper than birch and 2, made from waste wood material, As I understand it, the blocks are densely crushed dust and bark, with no added glues, 

OPP.  Good idea ! I will look into light machinery to maybe turn my SRC willow into a drier heat source with reduced seasoning time, perhaps by chipping

A few on YouTube mixing the cardboard etc with sawdust, seemed to make a big difference to the burn time and heat. 

My idea , was that I could throw a shredded newspaper into a cement mixer , with a pint of water , and a cap full of pva glue ,  then when it's turned to mush , throw in oak sawdust from the chainsaw , then once its throughly mixed , press it into logs or blocks. My idea was to do it on a larger scale than just using a few old newspapers.

But is it worth the effort?

This is the thing that's stopped me from doing it .  I don't know if it would be an efficient use of my time and effort . It's a lot of trouble to go to , if the end result / product , isn't very good.

If its worth the effort I have no idea. The chap I watched was making quite a lot of them in a large bucket with a stirrer attached to a drill, he had soaked it for some time and turned it to mulch, added thr sawdust and used a bearing press to compress the blocks amd squeeze the water out. They looked substantial.
