Making calcium acetate from clam shells

Hello people ! The preparation of calcium acetate from clamshells is presented. The procedure is analog to eggshells. It is another example of getting resource from food waste. Procedure can be extended to snails and oyster shells.

Thanks for the video!
I have a couple of questions, I hope you shed some light on my lacking knowledge 😅
What’s the purpose of the treating the “jelly” with the acetone?
And just for clarification, the mentioned residue is what doesn’t make it through the cotton plug?
I know other methods where it’s filtered then the filtrate is evaporated - that’s what’s thrown me off.
Once again thanks for any light you can shed 😃

Thank you for watching and comment. Acetone treatment serve to dehydrate the jelly and remove impurities. I did also with eggshells calcium acetate. Yes, what remains in cotton plug is residue.

@@zodd0001thank you 🙏🏻

Awesome video as usual, lovely to see.
However why didn’t you fully crush up the clams
Wouldn’t that speed up the first step up by at least 2 days

[@zodd0001]

Really thanks for comment. I did not crush shells completely into powder because I have no means to. The meat press required hours of smashing. I have a grinder but it is good quality, I use for cooking, did not want to ruin blades for an experiment. To speed up, I think use 15% acid is enough. I would like to scale up to kilos when I have the possibility.

if you please, what is the use for the acetone?

[@zodd0001]

Hello, acetone remove organic impurities and residual water.

@@zodd0001 got this. thank you so very much. going to use the calcium acetate for my plants - more readily available source vs. calcium carbonate or calcium sulfate...blessings

[@zodd0001]

@@paulbraga4460 yes, that's true, acetate is more water soluble than sulfate or carbonate. Please, share the video in agriculture community.

[@paulbraga4460]

@@zodd0001 wow! means plant mineral nutrients like copper, zinc, iron, manganese, potassium, magnesium, when in acetate form instead of sulfate (agriculture uses sulfate of these most of the time) it will make a great difference...question of course is how convert sulfates to acetates. calcium acetate is breakthrough because calcium is difficult to get to the plant and is immobile as a nutrient🙏

[@lokzekshen3887]

if i use acetic acid glacial 99.5% need how many days?

[@zodd0001]

Thanks for comment. To be honest, I would not use higher concentration of acid than 12%, but if just to know, try to estimate doing a proportion.

[@paulbraga4460]

100 grams of clam shells - 1 liter 6% vinegar - another liter of 6% vinegar after 2 hours -

[@paulbraga4460]

4 days after, unreacted shell remain (point is knowing how much vinegar to use for different calcium sources - i wonder about bones being used - also has phosphorus) - mixture is filtered through cotton plug. heat over low flame to reduce volume and then later just exposed to the sun to dry ... treat this with 200 ml acetone and then filter through cotton plug...dry residue on paper - end product is 122 grams

​@@paulbraga4460yes, to me the experiment has gone like that.
