The first batch of pulp made 29.5 small briquettes and 4 fist sized briquettes. Each one burns for about 20 to 30 minutes in the pellet stove and leaves behind a fine white powdery ash. Fly ash and air borne particles seem to be at a minimum.
The second batch made another 20 small briquettes of just pulp, 10 with some dryer lint added, and another 10 with coffee grounds. It seems I had about as much pulp in the second batch as the first. I did make one 3x3x3 briquette to see if it would work in my twig stove before I realized that most of the small briquettes could simply be put on their side lengthwise and would probably fit.
Some notes, I will not do more with dryer lint. The lint had some very large strings in it and caused problems while blending with the paint mixer. Lint is better used for fire starters. Though it is not my favorite for that either. Also hair, human and dog. This will stink during a burn so these briquettes will need to go into the pellet stove and not in the charcoal grill.
Used coffee grounds required a lot of very finely pulped paper and did not compress as well as expected. I started out with a 2 to 1 ratio and ended up needing to up it to 4:1 and giving it an additional blend. I know coffee grounds will burn and will be effective but I don’t really like working with them in this manner. The odor of used coffee grounds was not overly pleasant either. This may have to do with my use of a bag of several year old Charbucks* that I chucked into the bin. It just smelled terrible and burnt and really was gag worthy. I will continue to gather and use the coffee grounds in my garden as a top dressing.
The paint mixer I was using kept getting long strips of shipping bag wrapped around it. I sharpened the edges and that helped immensely. But this might be helped through the use of a blender. I would only use that method if I hoped to use the pulp in an art context. Generally from here on out, I will not include those Amazon shipping bags in my pulp. It’s shocking that after a week plus long soak they are not breaking down at all. The strips of those bags are still very solid. It really makes me wonder what the hell is in them or how are they treated to keep them so resistant to breaking down. It’s bonkers. It does make me wonder if they could be used as a planter for flowers or other non edible plants.
Over all I made60 briquettes that can be burned in a charcoal grill and another 10 that can be burned in a pellet stove or other seal style burn chamber.
*We bought the bag several years ago while on vacation and left it at my parent’s place and no one had touched it in over 2 years. I brought it home and decided to just chuck it into the bucket with everything else. We have not bought any Charbucks since. *spits at the floor* union busters.
