Thread: sawdust brickette

This has been asked before, no one has yet got the answer.

If you find the solution we will all be glad to hear it.

I reckon 9 parts water to 1 part pva will do the job as long as the bricks are clamped till the glue dries.

Tryed it, also tryed shellac.

Dont work.

What about flour and water??

Maybe try over cooked rice. ever try to get it off a pot when it dries?? Apparently they have dug up old houses in China that used rice as mortar for bricks.

There is an "Innovations" catalog available but I'm not sure where to get them though. You can buy from this catalog a "press" for making brickettes made from newspaper. Getting a catalog would be handy just to see the "press".........

It was rice flour mixed in with the regular mortar, makes it go real hard.

So does lemonade, the fizzy type. I guess they didnt have fizzy drinks way back then.

What sort of morat are you talking about?
Would it work if you combined newspaper, water and sawdust? This would take care of all those weekend newspapers we all seem to collect(for the weekend classifieds to find tools/timber) and the sawdust we create when we aren't looking at those classifieds.

Google is your friend.

Check this thread. 'Fire Brick' about halfway down.

Also, some people were using wax mixed with the sawdust.

I remember the combustabrick maker from the early eighties.
You just used paper and water. If you combined the wood dust with paper I don't think you would have any problems. There is no glue or binder in most simple paper it just sticks together.
Try 50/50 wood dust & shredded paper soaked in a plastic bin overnight & compact in some sort of press. Like the ones probably still offered by the direct marketers.
I think it was KTEL who had the press originaly.

A bit of research on pellet stoves could help, they are a combustion heater that uses sawdust pellets for fuel. The pellets are fed to the heater using an integral screw feed.

They are reputed to be very efficient, and are in use in Canada IIRC.

May be able to track down a mob that makes the pellets for some info.


Cheers.............Sean, screw fed and happy

The industrial briquette machines use only high pressure to compact the briquettes together. The only problem is that they also cost around $40k for the cheap ones. I suppose that wax could be useful, but be careful, It is extremely volatile near heat.

Glue may be toxic. Why not use non toxic wax. If you use sufficient pressure the sawdust should "plasticize" and form a brick.
