I compost coffee like this and it is soil within about 18 days. Coffee is sterile since it has been exposed to high temperatures well over 100c - hence why it is VERY slow to break down when mixed with other inorganic materials like paper. I heavily inoculate my compost pile with the mycelium of an active compost pile for immediate heat up. It may well have something to do with your tumbler as it is not on the ground where all the microbial action comes from to infect the pile itself. Also the tumbler is just shy of the 1 cubic meter the pile needs to be to fully heat up. Instead of paper I use saw dust or just chaff from roasting as you used. However as you discovered there was a lack of carbon and your compost slowed right down - my ratio is 1:1 or even higher of carbon. Plus a lot more water - I would be wetting the coffee and not just the paper - although yours appeared to gather water after 6 months. Finally after the first 4 days of heating turn the compost every 2 days and it should be done after 2 weeks - fully broken down.
Coffee grinds and shredded paper to make soil,simply amazing and the best part about the whole process is everything is FREE,really good video my man 🙏🏾
That material would be great for a worm bin. The red wigglers would quickly turn that into real high quality worm castings. Great video, very well presented. Cheers from Ottawa, Canada🍁

Maurice, I did a quick google check and it looks like this version might have been discontinued. There are a few out there. Cheapest was $160 put might not be something worth shipping. Here is what I searched to find "Lifetime Rotating Composter (80-Gallon)"
Looks like the same one I have. In my 9 years of use, I have found the latches to be its weak point. I have dumped the batch a couple of times while turning. I find myself needing to constantly re-bend the spring shape back into the latch. Other than that, it has served me well.
Its a good idea to have at least five different ingredients. This is as per the Berkeley method. It gives more variety of nutients. That looks so pretty.
Great video! Thanks for the complete walkthrough. I have a small yard and my compost piles are taking over the usable space. This would be a great addition to my home veggie garden
I like that composter ...my Great Aunt had a (I forgot what they call it)...chopper digester in her sink ..which helped start degrating material .. and then at end of her garden ...she kept it all in a chicken wire holding encloser....was very very wormy and oxygenated.
Nice to see someone else using paper. I build 4 or 5 piles a year using the rapid composting Berkely method. During the summer, after we're through the autumn leaves we set aside, I switch to shredded paper which I stockpile. Since the paper has such a high carbon content, it matches well with summer's profusion of greens, like grass clippings. Caveat: paper has a very high carbon content with near-zero nitrogen, so the best compost ratio is like 5 parts years trimmings to 1 part shredded paper. BTW, we also compost our coffee grounds (and tea bags, BTW), but our local Starbucks does not save their grounds for gardeners, sad to say so we miss out on a bulk high-nitrogen material.
It helps if you go to your local Starbucks and ask them if they will leave a bag of it out back behind the dumpster, after you have ordered a coffee. Get to know the employees and they will help you out.
@@aroberson3583 My local Starbucks won't for whatever reason, and I'm pretty cool with them. They said their district manager said "no." They did not know why/ I tried speaking with the district manager with no luck, so I gave up.
My primary materials are a decade's worth of pinecones and needles, other yard waste including limited grass and leaves when available, cardboard and various paper, and food waste from two people. I run everything but the food scraps through an electric chipper/shredder twice before starting the composting process. The cardboard and paper come out larger than the shred you use but the coin-sized pieces are soft and fluffy to the touch. The pinecones and needle come out fine, almost powdery. Any suggestions on how to best process these ingredients?
The bleach (chemicals) will all be decomposed through the process, the bigger issue would be inks. In an ideal situation I would use leaves instead of shred paper. As always additional types of materials benefit the overall compost just as if we were to eat a varied diet compared to a diet of only 2 item.
How long does a composter like that last? Does it become brittle from sun exposure? Does the paper exclude the resulting compost from use in an organic garden? Does the heat rise enough to kill weed seeds?Really impressive work!Thanks!
Hi William, backyard compost bins do not kill weed seeds. The temps do get hot enough but not consistently through the entire pile (the sides). These bins do have more moving pieces and more to break over time, though I have not found the sun / brittle to be an issue.
Hey Pete, do we need to assess the weather forecast before using this method. As I reside in tropical region. what could be a feasible way of using coffee grounds
Arielle, for batch composting you do need a large amount of mass to heat up (activate the bacteria) and to keep the bin warm. I have found 80 gallons is about the minimum size.
Do you worry about the ink on the shredded paper? When you go get the coffee, do you leave a bucket with them for the day, or do you just pick up whatever they've got right then + there?
Great questions. For the most pure compost I would substitute leaves for the shredded paper. The inks would be the concern as some are a plastic polymer. I do put my faith in the decomposers up to a point (as they can break down oil, rubber, etc.). Microplastics are no fun but are inert. As to the coffee grounds yes I leave 5 gallon buckets with plastic snap on lids and then swap out with clean ones.
this is a great question. The white is due to a bleaching paper process - typically chlorine dioxide. Chlorine is a micronutrient for plants and at the levels used the decomposers should handle this and neutralize into food. The bigger issue is making sure shred paper is clean of all plastic (credit cards, windows from envelopes, etc.). Also the inks are chemicals. My gut instinct is the Fungi, Bacteria, Invertibrates will turn these inks into usable food sources but if you want to be pure you can substitute dry leaves for the shred paper.
What is the minimum amount of time you would allow this process? It seemed like it was getting close at 4 weeks out, then you jumped to 6 months. I have a 96gal tumbler that I am hoping to use to create as much volume as possible for newly made raised beds. Thanks!
Great question! Honestly I forgot about the compost during the winter and thus the longer cure period. 3 months is probably the quickest I would want to use the compost and I mostly use as a mulch so the soil (worm) organisms can further cure and bring the organic matter down into the soil to provide the nutrients for my plants while any chunky/woody (carbon) material remains above the soil surface level as I don't want that in the soil robbing nitrogen to decompose the carbon.
@@composterrecycler Thanks! I wound up sourcing a better variety of materials than I had anticipated, but the final batch still wound up being at least 30% coffee by volume. I have definitely smelled worse compost piles! 🤭
Yes I am looking at different ways of composting this seams great I do like tumblers but they all seem to have problems maybe it is keeping weights down
@@mllokie9075 The weight was definitely a problem. (We wound up leaving a batch in there all winter, and it wound up leaking tons of rain, so it tested as depleted. Tons of worms though, so we'll still use it.)
No expert and I won't attempt to speak on every piece of paper or cardboard ever produced. I highly suggest everybody does their own research. But the majority of ink is plant based dyes. Same for most glue in cardboard being rice/starch based. Composting breaks it down. It's a non issue. Same for modern pressure treated wood in gardens. There is no difference in measurable amounts of "toxins" in crops using PT wood compared to no PT. Most people unknowingly eat and drink far worse things on a daily basis.
I’d like to do a ph test of that compost. Coffee has a ph of about 5.0. Thats acidic. Plants do best about 6.0-7.0. Once you establish what coffee grounds and cardboard makes in the ph, you can add something like baking soda or lime to get it in the right range. If the ph of that soil is 5.0 the plants won’t uptake the nutrients in the soil. Ph is important. Why not just use shredded cardboard and grass clippings? Throw in some kitchen produce scraps. If cardboard is too labor intensive, you can always use shredded leaves. Its become popular for coffee drinkers to add a couple pinches of baking soda to their coffee. It makes the taste smoother and helps people with acid stomach drink their coffee and avoid acid reflux.
The worms come once the temperature drops and they are part of the finishing process along with fungi and other invertebrate decomposers. Build it the worms will come.
I think "hot composting" is more of a need if there are suspected pathogens in the materials or, more commonly, weed seeds since the heat will kill the weed seeds. Also "cold composting" the alternative is more often used when there's no rush to get the compost.
@@JWHealing Ahh, good to hear. This was my line of thinking as well but i am no expert. Thanks for the insight! Ive been having success so far doing the 'cold'method but it most definetly gets warm toward themiddle and bottom

this is shred copy paper so yes ink. In an ideal situation I would use leaves or chaff or wood only sawdust or other natural carbon sources. I have discovered that coffee does indeed break down into compost on its own (see comment below. @audas
Turning that tumbler reminds me of The Price is Right 😂
About to attempt the same with 1 ton of coffee and autumn leaves, backyards gonna smell like Starbucks
After watching this my local coffee shop is now saving their coffee grounds for my compost. Thanks for the tips .
Yay! so awesome. Thank you!!
Amazing, happy composting!

So cool. I’d like to try this… I wonder if mine would turn out sooner if I did this on a smaller scale? Hmmm might have to try!
I think this could be complete in as quickly as 8 weeks. I forgot about it but that added more cure time :)
Arielle, for batch composting you do need a large amount of mass to heat up (activate the bacteria) and to keep the bin warm. I have found 80 gallons is about the minimum size.
I shud make my own 1000 gallon tumbler
how can the worms get to the compost when its off the ground? is this soil as rich as the compost with the worms?
We add shredded dried leaves and crushed egg shells to the coffee grinds. At planting time we mix them in with our soils for potting.
I am also trying to experiment on small scale for composting. Great video. Does it have to be black container? Thanks
any container 80 gallons or bigger will work

no water only 10 gallons of extra paper. Luckily we got the moisture right at the build and then additional through the weather.

Always wondering the effect of those WHITE chemical when used as a compost in your plant.
this is a great question. The white is due to a bleaching paper process - typically chlorine dioxide.

The bigger issue is making sure shred paper is clean of all plastic (credit cards, windows from envelopes, etc.). Also the inks are chemicals. My gut instinct is the Fungi, Bacteria, Invertibrates will turn these inks into usable food sources but if you want to be pure you can substitute dry leaves for the shred paper.
Thank you for a reply. Have been using dry leave for the brown material and it worked great!
Is the bleached paper/ink a problem?
Thanks for this useful info! Do you get any ammonia odor while it cooks? And if so do you remedy it or let it do it's thing?
D.E.
Where do you get the plastic material to wrap your compost?
So this is just 1:1 ratio by volume? Coffee to Paper/Cardboard?
Roughly, they did throw in some extra paper part way through though
Do you turn that daily or when?
I turned only when I check on it, which was every week or so for maybe 4 times and then it sat unturned for a while.
I've read that caffeine will prevent plants from growing. Have you used this stuff in your garden and did your plants grow in it?
I doubt theres much caffeine in there since it was mostly extracted in the brewing process
The caffeine ends up in the coffee people drink.

no need a compost starter?
Does anybody have a reliable source for finding out what cardboard is glued together with & if it's safe? I can't find a definitive answer. Thanks!
Hi Pete, is there a recommended ratio? Thanks.
That depends on the feedstock - this batch of compost was 50 gallons (paper/chaff) to 40 gallons coffee
