I know you can turn it into fire logs I've seen it done it's a bit of a process I'm not sure if it takes more time than it's worth but I imagine once you perfect that process you might be able to make it more worth the time invested especially with people using things like rocket mass heaters it'd be a lot easier to throw One login there that you know will last so many hours maybe even get through half of your winter without ever touching natural wood just burning Amazon boxes and junk mail turned into a log
The process I saw the simplest way was with 5 gallon buckets they would 1 with water put a bunch of paper in it let it sit overnight and Stir It Up Until It's slushie of soggy paper or as I like to call it garbage Goo then you pour it into a
bucket with holes in it put another bucket inside of that and then sit on it to compress it though I imagine using an actual press would work much better but once compressed it squeezes out the majority of the water and then you have to let it sit and dry out at that point they should burn for comparable amount of time as the store-bought fire logs
I would like to test this process out more come summer but I thought perhaps I could spare myself the work if other people have already done some testing
