oh now that i see the pile. That can dry up to be good firewood. IF it is free make charcoal, which also happens to be biochar, which needs to be ‘primed’ with nutrients before adding to a garden, the easiest ways are adding it to a compost pile, but it looks like you have chickens, and you can feed it to them. They eat it and It cuts the smell down as well. iirc they also like to bathe in ashes
The woodpile you have may not work well with the open pit charcoal makers.
This is a thread on making charcoal. Matt made a lot of charcoal. There are two basic methods. The one I showed first is an open retort method, where you burn where you are making the charcoal, and there is a closed retort version where you put the wood you want to char into a sealed (with venting) container and heat it from the outside and bake it with heat from the outside. It off gases burnable gas which can be used to continue to provide heat as well. They both work. While there are a lot of variations on how to make it. They fall under those two broad catagories.
I usually burn larger chunks for a firewood, and the brush gets made into charcoal. I use the closed retort method for making charcoal for art drawing. Literally it is a can with a few small holes in it, and I drop it into bonfire. but people do the same thing with 30 gallon barrels inside a 55 gallon drum.
this isn’t too bad for a small batch if you have a firepit. just to demonstrate simplicity. I wouldn’t use a zinc plated anything in a fire because of the zinc gases which are kind of dangerous, and I would store it in metal. I would also at least cover the hole when I was done. a metal 5 gallon bucket, paint cans, etc. all work as well. You don’t need tons to get started.
Free free to jump in with questions. The only bad question is the one you didn’t ask.
