sawdust brickette

[shayrebel]

i produce sufficient sawdust to warrant possibly making them into brickettes for burning in fireplaces(personal use only),now does anyone know of a binding glue that i can use and is cheap

[ozwinner]

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.

[ozwinner]

Tryed it, also tryed shellac.

Dont work.

Al :(

[echnidna]

What about flour and water??

[Douglas Fir]

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.

Wow, a thread resurrected after four years.

Why bother with briquettes. We just put sawdust and shavings in large paper bags, and stick them in the slow combustion stove. Burn fine.

Beware the living dead:o

Was will act as an accelerant and will reduce the burn time of the brick.

there is no need to add anything but paper in a decent portion... even saw dust that has got damp and lest in a pile will clump and stick together with no preasure.

most paper is made without glue or binders.

So all you realy need to do is mix up you wood waster with some shredded paper soak it well and give it a bit of a squash.....seriouly the biggest issue is drying the bricks before they go mouldy.

Peat briquettes were big in Ireland and a friend there made a briquette press and sold the produce by the truck load.

I looked over the press and it was nothing more than a pipe fed by a huge hopper containing peat of a certain M/C. The peat was compressed in the pipe by an hydraulic ram and came out of the other end looking like highly polished ebony and was as hard as coal. It was then bound into managable 'bales' with plastic strapping.

When I lived in England, I also used to see similar briquettes made from sawdust and they looked like they had been produced by a similar process.

I don't know how much this will help but this Rojek machine used Hydraulic pressure.

now you asked for a cheep glue solution and this is very expensive, but it strikes me that it must be possible to get a old press and a a former and .... well - just maybe, not really my field but I knew this machine existed.

[soundman]

we all know that you can get almost anything to form up into a brick if you apply enough preasure.... but I don't think anybody is about to go to that expense to make bricks out of wood waste from their home workshop.

It is reasonable to expect that people may use one of the already available paper brick presses or build a simple form and lever press.

might be an old thread but its 1 that any of us in a cooler climate think about regularly!
