Dude. I built a fish cleaning, vegetable wash station for Fred last year. Instead of building a whole new thing I'm gonna install the disposal ON THAT now!!! Thanks!!!
That garbage disposal is going to be hating life. "Wait, why am I not being installed in a nice kitchen? Why am I not being fed the leftovers from dinner? WHAT KIND OF WATER IS THIS?!?!"
Oh it’s on now! I’ve burned up one leaf vac, clogged up another and dulled the blades of my chipper running biochar through them. I already have a sink with double drain boards in my potting station….and I sell disposals at my work.
If you used an old sink instead of a cutting board it would act like a funnel and it would be easier to get stuff into the bahfeemarator, and a sink already has the right size hole in it
If you had the money to spare, you could buy a plastic utility sink. it would already have the drain hole, (though it might have to be drilled a bit larger to fit the garbage disposal) and would already have the legs built in..
I would think adding a funnel in here somewhere would be great. Maybe a funnel with a cone-shaped top half for easy filling and a cylinder bottom half (inside diameter matched to the mouth of the bahfemerator ) for "piston-style-ramstuffing" Plus some simple way of mounting/removing the funnel as needed/preferred. Or even install the funnel between the table-top and garbage disposal (make the table-top hole bigger to fit the funnel mouth as the new bahfeemerator mouth)...of course one can get overcomplicated in persuit of "IDEAL"...am I overthinking? ...I probably am overthinking...
Hmmm, I have see garbage disposals used to grind stuff for bio-digesters. After seeing this it makes me wonder if passing the bio-char through a bio-digester would be the ultimate way to charge it as the slurry that comes out is a very rich fertilizer.
I've thought about this before while cramming tons of apple cores down my drain. If only I could catch all this stuff from my garbage disposal I thought... Now after watching this I'm on the lookout for a kitchen sink on the side of the road to make one of these... I feel like it needs sides. 🤷
Definitely aeration would be good or straight in the compost. There's plenty of research scientists like Elaine Ingham who say allowing organic matter to go anaerobic actually creates many harmful chemicals including formaldehyde that actually slows the good guys down.
@@shannonsexton8921 I like Elaine, but people have been using anaerobic composting with success for a long time, likely long before miscroscopes and electricity etc to power aerators etc. I might be more beneficial to do that, also a ton more work, and one wrong move makes it anaerobic again. Lots of science shows she is wrong about it, could be that, could be the current science is wrong, one thing for sure..... lazy anaerobic composting works 🤷♂️
@@davidthegood probably get a sink at the dump and then it’s a direct replacement for the cutting board. Just screw it to the frame you made through the flange on the top edge. Otherwise the idea of charging the char while crushing it is brilliant I usually just dump it into the compost pile and forget it’s in there.
@@marka9292 That's what I was thinking. I have all of my friends who do remodeling work watch out for stuff like that. Of course in my town all I would need to do is drive around and look at the crap in everybody's yards. LOL!
@@davidthegood Do you have that plugged into a GFCI outlet? Being electrocuted will delay your video release schedule! Also your safety is important too.
Idea: most (all?) disposals have an inlet to accommodate a drain line from a dishwasher. Here is where the charged water could flow into the grinding chamber via drain hose. Elevate the charged water supply (as noted by several above). Maybe even add a valve or foot pedal activation--then you can adjust the flow as needed with less mess and no-hands operation. Such a great video.
AWESOME!! David you need a hopper to make things easier and more tidy lol. A sink would be good and would act as a good holding tank allowing you to fill and mix your materials before moving down into the garburator. But the sink is still flat on the bottom. I think a large funnel or hopper of some sort would be better. The materials would constantly fall towards the center and down into the garburator with minimal effort from you, just simply poke the pile to keep it moving. It may be a little more kid user friendly with a hopper, ;) gotta keeps those kids busy right! lol. Either way great idea and the end product looks like a sure winner whatever way its used. Great idea. Thanks for sharing cheers!
Great idea! Funnel might be nice. Maybe adapt a large HVAC reducer to the top. Could just grab a sink from a remodel or scrap yard. Maybe go the Seinfeld route & install a garbage disposal in the shower/bath & reroute the grey water!!!! Ok, I'm putting the coffee down.
This is brilliant. I spent hours trying to break biochar up. I love the end result and consistancy of the ground product you have there!! I’ve been a big composter all my life. And now, living in FL. With SAND! I’m liking the biochar idea a whole lot! This week I been making your squash pits! Seems I now need a garbage disposer! What’s funny is, people who don’t or can’t garden just don’t get us extreme gardners. They would think it CRAZY. 🤣 Thing is though, our gardens thrive where others fail! Love this vid David the Good! Good job! 👍
Pretty neat! I always thought it'd be smart to have a dedicated compost blender, instead of just the little kitchen pail. Puree that stuff first, then add it to the bin/tumbler/pile. That idea seems like child's play now.
You could make a "sink" using a plastic wash tub. Cut a hole in it like the cutting board and use the sink flange to sandwich the tub and the cutting board together. An extra 2-3 bucks at Wallyworld. All the water and food scraps, biochar would be funneled to the grinder. Less mess. UV light would probably degrade it so as other viewers have mentioned, a regular sink would last longer.
That biochar slop would also be good to feed to your chickens for parasites & nutritional value. They probably would start popping out eggs like a slot machine.
I'm a bit surprised you didn't use one of those toggle switches with the red shut off cover. Would've upped the cool factor a bit I think. Badazz machine tho man!
Great work David, Herrick would be proud. I hope you experiment with all the different ways to use Bio char and make a new video using each one. Use the same kind of plants maybe one or two for random control. Thank you for pushing gardening forward and making us think! We are all secretly hoping for a planet whizbang gardening book 2. Herrick, come on man. : )
I bought a bag of lump charcoal today and I'm going to try to just send it through my Kaz Chipper tomorrow with the bag attachment on to catch the biochar.
The experiment was successful. I was able to send an entire bag of lump charcoal through my chipper and into the side attachment bag. Very little was lost as dust.
Very cool. I think I will build one with a bucket for the "sink" and a second upside-down one as a shroud to protect it from rain. Three legs coming off the shroud and it will be freestanding. Mine will be more for pre chewing chook food than charcoal, but it all goes on the compost pile for the girls to work over anyway.
Well damn now I know what I'm going to be doing this summer thanks allot I won't be able to get that out of my head now until I do it once you hear it you can't in unhear it
Does the diisposall have a built in dishwasher drain? You could install a connector for your water hose to that and have constant water without having to spray by hand.
@@davidthegood perhaps put your charged water in a garbage can or something and use a simple pump to run it into the disposal/grinder. Could be a pump you plug into 110V, or a bilge pump that runs on 12v so you could use a cheap solar panel to power it.
For those in the US and who have a Costco membership: the garbage disposal sold at Costco is better than anything currently offered at Amazon. Bought one for this design and is an absolute beast for this design, at almost the same price as entry models on Amazon
Super excited to see where this goes, I'm always looking for ways to level up my teas, composts, soil, and have more of it using more never ending materials!
*Great video. I too love Herricks ideas. Anyone who doesn't have access to a pond just throw in some ascorbic acid to your water and stir that will do the trick or add a few air stones with a pump and let it run 24hrs.*
Thank you! I'm interested to see how long the disposer will last. BTW... I still can't "compost my enemies", cause I haven't received the shirt I ordered in January.
Brilliant! I wonder how long it will hold up to the rough grind? My kitchen disposal blade gets jammed with any hard nuggets or bits and then I have to stick my hand down in there and unwedge whatever it is. Is this some kind of industrial strength disposal?
To loosen a stuck disposal, before sticking your hand in it...there is a wrench that should have come with it (if not, a properly sized hex wrench works)... The motor shaft comes out underneath the disposal and can be turned with the wrench manually to unstick it. Much safer
@@thebigshmoog good advice. I'm still wondering how well the blades will hold up with this kind of use, as mine gets stuck pretty easily with much less hard chunks to deal with.
I'd imagine, having made a lot of biochar myself...pretty well. The char is pretty soft... I think it's the few random uncharted pieces that may give it an issue...
It'd be cool to put a big funnel on the top and then a drip irrigation line going in that you can turn the water on once the grinder is on so it auto-drips water while the funnel of food gravitationally moves down.
With Paper Crete, they create "Tow Mixer" Where They take the back drive axle of an old truck, and invert it so the drive axle is pointing upward. Then they mount a spinning lawmower like blade and a tank cut in half on top of that so that everything inside gets pulverized when you tow it around the yard. Might be good for larger batches.
Will the Mark II see a switch box above the work area and flood plain of the water? Just a bit more separation of electricity and water would be a little less sketchy I think, especially for others that follow your lead.
I just use a wood board and a rolling pin. For the tough bits{after cooking in a retort} like soup bones, snail shells and seashells, a mortar and pestle. A funnel would do wonders for your setup.
It’d be neat if you could get a few half barrels and put the ground up char/food swamp water mixture into them and have it sitting and ready to use to put under new beds/plantings as you make them? I found that the lumps of charcoal I put into pots last year, this year are very easy to break up this year.
Hi David. I've been thinking about this a lot. I think if you got a 6" pipe Like PVC or something , you could cut an inch or two section and either glue it onto your cutting board or mortice it in So you could feed your materials easier. I think that would be gooder.
I have a lot of brush I'm getting rid of. Think I'll be using this one. Have you ever tried a 55 gallon drum with holes in the bottom and a 55 gallon drum as an after burner? Epic carbon burns.
How is the power switch water-proofed to prevent electrocution? Pouring water onto the flat surface where that switch is sitting a few inches away seems rather risky, but I'm no electrician.
I’m curious to see how the smaller biochar size works out. Smaller biochar size should increase the rate that it can be charged, which might be a more efficient option. But larger biochar size might hold nutrients for longer periods of time, which maybe would save the hassle of having to make more right away.

I would be tempted to take it one step further and install it in an old sink.
I was thinking of the same thing. He could buy a used sink for this project.

I had the 1HP Waste King disposal at my last house. That thing is an absolute beast.
You could improve that with a sink. It would give you a hopper. Just dump everything in the sink turn the grinder on and start pushing it down.
I should set up a go-fund-me. "Please help me buy a sink and a super-powerful insinkerator, plus more lumber."
And 95% of the cost is the lumber...
I think a sink is a good idea.

Ooooh much better than chopping everything into tiny pieces before throwing it into the compost bin spinner thingie. This might be genius for me.

Does the diisposall have a built in dishwasher drain? You could install a connector for your water hose to that and have constant water without having to spray by hand.
It does, but I would have to find out a way to have charged liquid flowing in.
What if you positioned the DFSW up on legs like a water tower so it could gravity-feed into the Bafeemarator?
@@davidthegood perhaps put your charged water in a garbage can or something and use a simple pump to run it into the disposal/grinder. Could be a pump you plug into 110V, or a bilge pump that runs on 12v so you could use a cheap solar panel to power it.
Beautiful! Needs a funnel like a woodchipper. :)
I was just thinking a woodchipper really makes composting one's enemies that much more efficient
That's pretty slick. Add another bucket and a small pump so you have a steady flow of water.

Interesting video.

Please keep us informed with results.
I like the char slop going straight into the garden idea but I wonder if it wouldn’t need time to age before planting.
How is the power switch water-proofed to prevent electrocution? Pouring water onto the flat surface where that switch is sitting a few inches away seems rather risky, but I'm no electrician.
If it's plugged into a GFCI protected circuit which outdoor receptacles usually are by code, then he is fine.
Next level
I’m curious to see how the smaller biochar size works out. Smaller biochar size should increase the rate that it can be charged, which might be a more efficient option. But larger biochar size might hold nutrients for longer periods of time, which maybe would save the hassle of having to make more right away.
Hey David great idea, but i would do 1 mod : put the switch on a pole higher than the splash / run-off line so you don't meet God too early.
Good idea
