hello David. What if we Looking create the plastic on big level. Say 15KG to 20KG ? what equipment we should use? what kinda boiler we need to use? What is the process for the same? We need to use the big glass biker or we can use the metal l? please advice?
Hello I'm a high school student that is currently doing experiments and writing a report based on biodegradable plastic. Can you please tell us the molecular formula and specific steps of decomposing bio plastic?
Hi, I bought a solder sucker which I can not buy replacement tips for. It cost $20. I want to make a wooden mold and make my own plastic replacement tips. I could make soft plastic replacement tips but if I can harden homemade tips I will be trying to make a plastic hopefully towards the teflon type of plastic. At the moment I could make homemade plastic using milk and vinegar. Will this mix harden using glycerol or would they perhaps conflict with each other? Thanks for your video - Nick
Hi thank you so much for share this so useful video . I want to ask a questions. How do we understand that bioplastics? So just looking at the outward appearance, we can understand is it bioplastic or not ? How to know it chemistry ?
because the water/ moisture in it evaporates thus the chains that were once far apart come closer together because it's not in a orderly form there are some area much bigger coagulated together and some not, this falls under irregular creation, now if you microstructured the formation in a dispenser which controls regularity all through out then you will get a well pan out consistent structure.
What purpose does it serve in the reaction? The solution was probably neutral at the beginning before the acid was added, so I know that the goal was to achieve some sort of property? What is that property?
Starch has amylose(linear chains) and amylopectin (branched chains). Branched chains do not easily form plastic, so we add acid to convert amylopectin to amylose.. and later base is acid to neutralize the acid added earlier.
At what temperature, do you bake it in oven? And i tried doing the same and when i decanted water to get clear starch, it was not in the form of powder, rather a gelatinous rubber like material. Can you suggest something?
actually, the acid can be substituted by vinegar here's a a very easy way of making it and a large quantity too: www.instructables.com/id/Make-Potato-Plastic!/
Wouldn't practical suggest the plastic being used for a practical purpose? Making a few chips of plastic is hardly practical. What can this plastic be used for?
I believe the purpose is a proof of concept. You can multiply the weight of each ingredient depending on the amount of plastic you want. But given the fact that conventional plastics are made using petroleum based methods I could see the practically in an alternative source based on simple starch. It would be more eco friendly & would more likely break down quicker in nature. Might be good for making bags, bottles, disposable plastic products such as razor casings & such.
Bioplastic like this can be used for 3d-printing, which allows you to create a wide range of useful and fun parts (see thingiverse.com ). PLA derived from corn starch is the most common bioplastic used for this, but some filament producers create plastics derived from potato starch as well.
***** After you have produced plastic as seen here, you shred it up into pellets. Then you use a filament extruder (like Filastruder), which you can then feed to your 3D printer.
Thankyou David Read! I'm startin to get a feel for this!
That's a helpful video. Thank you.
A small query: Why only Glycerin is being used?

What temperature have you maintained while heating it
thus it is a good demostration could we use it in science exhibition as working model
is this PLA? could I put it in a filament extruder along with PLA pellets to make 3D printer filament?

what if i looking to prepare plastic on big scale.say 10kg to 15kg?what is the ratio of chemicals we must take .
Hi thank you so much for share this so useful video . I want to ask a questions.
How do we understand that bioplastics?
So just looking at the outward appearance, we can understand is it bioplastic or not ? How to know it chemistry ?
How long will it take to bake and how many degrees Fahrenheit?
to what temp is it heated to for the 15minutes, also what would be the biodegradation time on this stuff?
Can we use your video's content in our research paper?
This is our SIP!!!man.thx!!!
Hi,
Is it soluble in water ?
hey, i would like to know about milk plastic,
how much time it will take for curing and how about mechanical properties.
Is it thermosetting or thermoplastic?
What a biopolymer is this? answer please
if i extract it from rice, can it still be turmed into plastics?
is it a thermoset?
Have you tested its tensile strength?
why did it turn to a sticky jelly type structure when I heated it in oven ?
because the water/ moisture in it evaporates thus the chains that were once far apart come closer together because it's not in a orderly form there are some area much bigger coagulated together and some not, this falls under irregular creation, now if you microstructured the formation in a dispenser which controls regularity all through out then you will get a well pan out consistent structure.
can this plastic be decomposed in the soil or water
Are there any other materials besides potatoes that can be made into plastic?
Why was acid and base used?
What purpose does it serve in the reaction? The solution was probably neutral at the beginning before the acid was added, so I know that the goal was to achieve some sort of property? What is that property?
fishin mid bama the solution of starch was acidic, by adding Na-OH or lye which is a base, he adjusted the solution to neutral or water.
to break the natural sugar polimers in the starch.
Starch has amylose(linear chains) and amylopectin (branched chains). Branched chains do not easily form plastic, so we add acid to convert amylopectin to amylose.. and later base is acid to neutralize the acid added earlier.
@@abcd7152 I need your assistance for making corn to plastic
Can it proof the water ?
That's some very nice spelling you have there.
At what temperature, do you bake it in oven?
And i tried doing the same and when i decanted water to get clear starch, it was not in the form of powder, rather a gelatinous rubber like material. Can you suggest something?
Yes I have the same query
Don't put it in oven just let its in air
Does it is a non plastic or plastic?
Is This Bioplastic formed
Is it also applicable on Sweet potatoes?
GREAT. THANKS FOR SHARING
16 years later, and still ain't no signs of widespread usage
Is this plastic edible?
i got A+++ from this experiment
Hello, may I ask the amount of NaOH to be used sir. Thanks!
you can put in NaOH until the indicator paper does not get red anymore.
whats noah ? thx
actually, the acid can be substituted by vinegar here's a a very easy way of making it and a large quantity too: www.instructables.com/id/Make-Potato-Plastic!/
is veg. glycerin can be use instead of just glycerin
is it necessary to have an oven or else heating is enough
I need that answer too!
Can you eat it
- again the water can be decanted off.
- if we dry the starch in an over, we get a white powder.
- to 2,5 gr starch , we add 25 ml of water.
i'm going to perform this experiment .hope to be successful-____-
Wouldn't practical suggest the plastic being used for a practical purpose? Making a few chips of plastic is hardly practical. What can this plastic be used for?
i was just wondering the same thing
is it possible to mold this ?

I understand how plastic is made but plastic chips is hardly in a form that can be used by a 3D printer.
***** After you have produced plastic as seen here, you shred it up into pellets. Then you use a filament extruder (like Filastruder), which you can then feed to your 3D printer.
waaaawoooooooo......awsummmmmm.....i lvu iiiiit.........
WHOA
POTATOES
thanks for the vid
Lol how do we buy HCl?
u can buy it in any market in the part for toilet cleaning prntscr.com/ivg517
Plastic can be turned into oil. (On bang goes the theory) so can we use potatoes>plastic>oil? That would be awesome! I challenge you to try it!
i see Stanelco are making this...share price only 0.4p
I used sour cream and butter and this stuff tastes terrible!
Can children in Africa eat this?
no, but with this kind of knowledge they can learn how to produce their own stuff ;-)
+Leonel Braga lol
both
@ase010 nice try :P
It doesn't work at all 🙄🙄🙄
muriatic acid is Hydrochloric acid
And yet we eat potato & wonder y r joints r all fckd up smh.
