So, amongst the many random thoughts bouncing around in my head is this one. I have seen things to roll newspapers for fire logs. I have also seen hand operated presses to make "bricks" of paper for fires. My thoughts are to make a mis of shredded paper and sawdust or shavings. Stir this in a bucket of water until well mixed. Then put it in a piece of PVC pipe with holes in a threaded end cap and run a press plunger down into the pipe squeezing the water out back into a bucket. After compressing it, remove the end cap and remove the mix laying aside to finish drying. It seems like this would make a reasonable amount of heat and fire for the house or cooking. I thought of this one day while taking out a bag of shredded papers from the wife's office. Your comments and suggestions for changes are welcome. If you do not think the idea will work please explain why. besides the home stuff, there is one heck of a lot of paper in recycling facilities that could be used I would think.

Drying this would be the catch. Thin enough 'log' to dry thoroughly, thick enough to burn well. Maybe paper mache mats that are rolled into logs. Best bet, try it on a small scale and see if labor is worth return. You can also make smaller pieces mixed with petroleum jelly and/or paraffin for fire starters.

I think if you squeezed enough water out drying might not be a big problem overall. However this would probably be best done during the summer when the temps would be high enough to allow better drying. I do suspect that it would be labor intensive on a home scale. I just wonder how viable it would be on a larger scale. |

Large scale? Use something more volatile than water like alcohol or naphtha and process in a recovery tank. Or just make fiberboard cylinders like carpet is wrapped around.

If you do not think the idea will work please explain why. besides the home stuff, there is one heck of a lot of paper in recycling facilities that could be used I would think. I'm not sure how strong the threads in PVC pipe might be. Screw presses (of any type) are capable of very high pressures so you might need steel pipe and threaded endcaps that can actually handle a lot of pressure. These bricks/sticks/whatever would probably burn well (as in length of time) if at least an inch thick. I've seen one "brick" mold that looked to be intelligently made with good provision for the water to exit. Using pipe means having to come up with drilled holes or slits cut with a narrow blade on an angle grinder for equal drainage around the mold. Just remember that every drain hole or slit is a weak place on the mold so how do you get maximum water removal and also limit the amount of pressure applied by the screw press? If you can get lots of "white copy paper" scraps (shredded documents) you could have relatively clean-burning "firewood". I've seen the rainbow flames created by burning Christmas wrapping paper so I would avoid any colored ink to keep possibly harmful combustion products out of the fireplace. Burning in a stove might be different except for the possible chimney deposits from the chemicals used to color the ink. |

Both look good. The first one if you generate - or have access to - LOTS of sawdust and have a large junkyard to find parts or have $1000 to invest. Either of the devices shown in the second one - one from Amazon, the other easy DIY - would work for most people. The DIY version in the second video I could probably build from piece-parts on hand. Finally a use for all the junk mail ;-) Amazon has single slot devices starting at $40US delivered and four slot devices starting at $98US delivered. Search Amazon for "paper brick maker". Do note that they only specify "paper" in the descriptions, although the maker of the second video uses the same paper and sawdust mixture in the Amazon device as in his own. Sample single slot device: www.amazon.com/Bits-Pieces-Newspaper-Maker-Heavy-Measures/dp/B00TR0Z3X8/Sample four slot device: www.amazon.com/Briquette-Manual-Machine-Household-Recycle/dp/B09WMMHPJ1/ |
