Coffee Briquettes - How to make Briquettes with Coffee grounds 

Well chuffed to have found your channel my first batch is cooking away quietly. It helps being old to have the patience. Thank you for the enlightenment.

I can't wait to begin experimenting with this myself. Thank you for this video!

I saw your video and found it very interesting. Thank you for sharing that! I shared your video with a friend (scientist, biologist and one of the smartest person that I know) and his first reaction was that "composted coffee is more efficient than non-composted ... that's impossible!". So I searched it up. Here is what ChatGPT has to say about it (caps emphasis are mine): "Composted coffee briquettes are unlikely to burn more efficiently than non-composted ones. In fact, composting typically involves the breakdown of organic material through microbial activity, which can REDUCE the energy content of the coffee grounds.", followed by "Non-composted coffee grounds retain more of their original organic material and energy content, making them more effective as a fuel source when dried and compressed into briquettes. The composting process is generally intended to create nutrient-rich soil amendments rather than fuel. Therefor, non-composted, dried coffee grounds are better suited for burning as briquettes." So, he is right! He believes that the only reason your composted briquettes are burning better (for you) is because they are actually much dryer than the non-composted. He believes that the non-composted probably had much more moister in them. If you figured out a way to extract ALL of the moister content from the non-composted, they would scientifically produce more energy! Just thought I would share that with you. Additionally, I burn a lot of firewood at home, and I am aware that hardwood burns a lot slower, and hotter than soft woods. Therefore, I was wondering if you actually compacted your briquettes even more, if you could extend the burn time, all the while produce more heat? So I ChatGPT'd that too: "Compacting briquettes more tightly can lead to a hotter and longer burn time. Tighter compaction increases the density of the briquettes, which can improve combustion efficiency by reducing the amount of air and increasing the energy content per unit volume." ... "However, there are limits to this effect. If briquettes are compacted too much, they may become too dense for proper airflow, which is necessary for efficient combustion. Finding the right balance in compaction is key to optimizing burn time and temperature.". Very interesting, no? I guess you could control your compaction with a N ton compaction machine and control the quantity of material, etc. You could experiment until you hit a sweet spot. It would be great if you could 'quantify' the results with thermal imaging, and temperature readings, etc. Anyway, great video, looking forward to more content and updates. Thanks Christian J.

I love how well you record all the days of what you’re doing in your notebook, that is something that I need to do better at. I typically just throw in everything I have and hope for the best

Can't wait to see the 'press' you've come up with. Loved seeing the briquette cut open - not sure what I was expecting ...wondered if it would fall apart! Your videos make me want to have a go with the coffee grounds and sawdust that friends currently give me for my compost heap but we don't have a log burner! 😃

Looking forward to the next one. Very curious about the replacement for the press. 👍

these are wonderous - love watching them. thank you again for making them. glorious beard as well! Love from Maine.

Good job matey. Keen to see your pressless method for making them.

That is just fascinating when you cut that open! I was expecting it to be solid, like a brick! Can't wait for the next one Jamie! Looking forward to the new mold design.

Such a great suggestion! I also use my coffee grounds to grow mushrooms, but one can only eat so much fungus... I'm definitely going to be using this idea! PS: Instead of measuring your shavings and fine dust in inches, you might consider getting a grocer's scale and measuring that in grams/kilos as well. I expect it'd give you a more exact ratio.

great love your work am in Uganda Africa

You've certainly done your research on these Jamie ❤

25 seconds since this was posted. First! Love your content! :D

Good evening from Australia! I’ve just stumbled upon your video today. Love the inventiveness, please excuse me if you’ve already produced it but have you made briquettes using 100% coffee grounds? I’d be very interested to see how they come out and how they burn. I’ve subscribed to see your updated videos.

This is quite interesting since I also have used coffee grounds from my shop. I want to try to do this at home but would you care to give the mass of the sawdusts/fine dusts and water? I don't exactly have a tub that big so it could be hard for me to estimate it with a few inches high as a reference. Cheers mate!

I have collected coffee grounds, saw dust and fine wood dust in roughly 50/25/25 ratio. These are mixed in a bin but so far I have not added water. Is the amount of water needed just enough to make the mixture moist, or to drench it? Do you only add water once? Do you need to cover this with plastic whilst it composts? I have made briquettes previously with sawdust and shredded paper where I completely soaked the mix and left for a couple of weeks. After using the press to briquette it took some time for the briquettes to dry out. Thanks for any advice you can give. Brian

I just found yr Channel and subscribed. How did you find out about making these AMAZING 2 hr burners?? Pete NSW Australia.

Great videos, new sub here, due to the algorithms bringing me here from the last video. Curious though, do you have a rough ratio of water/coffee/wood? I figure a person could make many type of "press" based on a tube type form, like PVC, smashing it like a chub of sausage. Rock on man, good stuff!

Crazy how the most viewed video on a woodworking channel is how to get rid of sawdust/shavings. On another note, when is the q&a happening?

Tlrdnr/ how do you seperate the dusy from shavings. Hello i recently found your channel due to moving into a place with a fire place and literally burning money so i have picked up saw dust from a wood shop but there is alot of shavings in it too like mostly shaving how do you seperate the 2

Why you dont just premix dry stuff before adding water. Also I would try making few small holes in bottom of the mixing bucket, place mixing bucket inside another bucket (one without holes) and after you finish mixing, then pullout the mixing bucket and let the excess water drain to shorten drying time.

Hope you had the extractor on to catch those coffee dust on the bandsaw😂

Any videos of them burning? :)
