I'd like to say thank you for coming to my workshop Darren @AbellTo. Great to meet you and thank you for the gifts. Next time I'll come to you, and I'll remember to give you that coffee I said I would. We were so chatty. Jamie
❤ greetings from germany. Im so glad to have found your channel and expertise on the briquetting process. Last Fall i cut down some hedges of maple and shredded them to sawdust. Then over the last 2 weeks i tried to make some briquettes out of it and dried them at 800w/35mins in an old microwave oven. The burning was great but very short, so i came up with the idea to somehow turn the material into peat/coal or some other more longer lasting fuel. I've read about pressure cooking the material at 200°c/20 atmospheres to turn wood into coal but i was not able to find a suitable cooker... Then i was thinking of partly decompose it like peat does in nature and now i found you and im so clad that you already did it successfully 😮. I dont have a supplier for coffeegrounds so i leave them out in the mixture.. but my next step is to build a machine to make my briquettes more easy. I think compression is not as important with decomposed materials as with raw sawdust, thats why i believe extrusion is faster and more simple than an hydraulic press. Peat itself is also processed this way. Here is a video of an old screwpress for peat 😊. Link ruclips.net/video/59Z7YIBMY5A/видео.htmlsi=hcBjbyE6IIC0dvNx What do you think about it? Thank you for your effort and content Tim

What do you think about it?
Thank you for your effort and content
Tim
What if you made them with a device like a sausage? Press 4/6 inch opening on the top down to a 3/2 inch, opening and forse through the hole
That would work.
So your using less water? When you mix the coffee and sawdust you add water and let it compost but not have it completely submerged in water
Correct. It works really well too.
Could you bake them in the sun or would it make them crumble?
It would bake too quickly and cause cracks like baked riverbeds. Slowly is better
Where do you get the briquette maker?
Only just found this. I normally reply within at the most a day. Google search briquette press
Do you add a pva to the mix ?
Not any more. Latest videos show a composted mixture that is quite sticky.
