I have been avidly making seaweed bioplastic after I saw your video. I have since made a dissolvable dress made of it for a sustainable fashion project. I’d be really interested to learn where you got the original ideas for this recipe from and if there are any tips you could share with me!
How does one farm seaweed? Do you buy a bit of ocean? Or is it just having a boat? If so, is there any regulations to worry about? I have been looking around and there isn´t really a lot of useful information about all that, I´d be very interested if you´d care to share your experiences. I´d follow that channel :)
@@Ludifant i think there are no regulations as such yet as it is regarded as such a problem at the moment? might be in the future though once more people realize this huge potential; if you have good sources for further research/ use, i m also very interested thank you!
Hi there Robert, this is brilliant - thank you so much. My only question is this: isn't this a corn-starch plastic? After all, it's 50g seaweed vs 250 g corn starch. I'm curious as what exactly the seaweed does in this mix? Is it a binder, or a plasticiser? Thank you in advance and keep up the great work.
Hi Rob , Love the videos. I was just wondering if you could try to make a seaweed bio-foam similar to the properties of polyurethane? I've been trying but finding it tricky to come with substantial results. Would be great to see what you could come up with. Cheers
Not a lot of sea weed around here, but I do have cut grass. Will have to see how that holds up in the mix. Grass clippings to PLA... That would be amazing... Amazinger, because this is amazing. I have some silicon molds for soap making lying around. Will see how the mix sets up in them. Play with different layer heights to see how it dries. Maybe see if it will release from a 3D PLA printed mold. Would greasing the mold help it release? May be better to cast a silicon mold from the 3D printed mold, then cast this stuff in the silicon mold... So many questions... This will keep me buzy
I was thinking the exact same think as matter of fact I was gonna cut the grass tom morning guest I'm raking it too. Wonder what the ratio is gonna be on like 50 pounds of fresh grass to corn starch. I also have some helix nano rebar material and hemp cotton and fiber glass
@@ThinkingandTinkering Does the seaweed have musceligennic properties that partner with the cornstarch to make the plastic form? No slime in grass. If slime is the magic ingreedent, I'm growing okra in the garden. Will have to try a batch with okra leaves too :) Seaweed is salty, too. A non-seaweed batch may need a little salt thrown in as well. Or maybe less salt is a good thing?
Thank you for posting the video, I watched the 2nd video 1st by accident :) That shrinkage might be an issue for my resin desk idea but still LOTS of useful applications!
I'd guess not. But I bet, with the right additives, it is manageable. Just like brittleness, strength, plasticity, rate of degradation, etc. Finding the right recipes is the hard work.
As I understand it, this is usually a question of what is at the end of polymers. So chemical additives. But that is a way of thinking that got us in the problems with plastics in the first place.. You could also go the other route and use shellac to seal things or tree resin. Both materials are quite abundant and completely natural and renewable. (Shellac is bug excretion, amazing..) I have been looking at bushcraft videos that show how incredibly easy it is, to get birch resin and spruce resin in a useful form. You should check those out. This stuff can be used for structural integrity and by adding a shell you´d make it waterproof. I am thinking of using a burlap base and rubbing it with this stuff as a fabric hardener. And then painting the outside with shellac dissolved in alcohol to make a very cheap and easy and especially free-form shelter in the woods. Like a permanent tent. Burlap is quite cheap where I live, because of potatoe farming.
I'm considering using this form of bio-plastic to make organic slow release fertilizer pellets. Perhaps if this bio-plastic was powderized, the powder could be mixed with dry organic nutrients such as blood / bone meal. The mix could then be heated and extruded through an appropriate mechanism to form pellets. At first I wanted to make nutrient pellets, then coat them with something like a bio-plastic to make them slow release. This is what I've seen done for slow release synthetic fertilizers. I couldn't come up with a way to use a bio-plastic such as this and apply a coating with a uniform thickness from pellet to pellet. The thickness determines the release rate, so consistent thickness would be pretty important if I were to try and coat pellets with something like this. By mixing the bio-polymer with the nutrient powders and forming the whole lot into pellets, it does away with the coating thickness issue all together. I think it gives a great solution to the problem, and I'm pretty sure it will provide a consistent release rate which can be adjusted by changing the ratio between the amount of nutrients and the amount of bio-polymer. More bio-polymer should make for a slower release, and faster with less. If anyone wants to try this, be sure to rinse off any salt from the seaweed beforehand. Seaweed tends to come with a lot of salt on / in it because it grows in the ocean, which is salt water. If you don't already know, salt isn't very good for most plants! Any thoughts on this idea Rob?
Can you do a follow-up video, please?Does this bioplastic dissolve in water or other liquids? How strong is it if it's thicker? How can it be made to be more durable?
This is great, a little slow to the party on this one but if that BioPlastic can be injection moulded, it could be made into 3D printer filament and potentially extruded on an FDM 3D printer?! Have you tried that?
Hi, I am wondering if this bioplastic will be brittle enough to hold a structure such as a wine glass shape. Is it water soluble or could i use it as a drinking vessel? Thank you!
It seems eco-friendly to make bio-plastics, not petroleum-based on oil. However, bioplastics that need to be decomposed with some heat are having a hard time processing them after production. PHA, which decomposes without heat, looks better in the future than PLA, where raw plastic decomposes only into heat. In the future, PHA materials will become more perfect eco-friendly materials. Is A Seawed Bioplastic decomposed without heat?
This is awesome. I'm thinking of making a bioplastic from algae too. Can I just order any algal powder to make this? Also the color is there a way to make it white?
Totaly on your wave length I suggested adding hemp fibres the pla soup mix for plastic forks to make them heat tolerant... I was inspired by operation piecrete (the floating sawdust ice armour boat ) You geniuse. . . . Crack on
Suggestion: Greeting from the US, I would love to see you try using Coffee Grounds as an additive. I have been watching a lot of gardening videos lately and stumbled upon a way to obtain large amounts of coffee grounds for free(I use it to sorta act like a multch/long term fertilizer). Your local coffee shops typically are giving it away for free by the poundfuls depending on the location and customers. Cheers
Hi Robert, thank you for the video. I need to make a bio rubbery substance that can be extruded into a 3d printer. Can you tell me what you would suggest I do with this plastic to attain this more rubbery substance?
What do you think about using nettles instead of seaweed, as a fiber content I think strong, as the bases of of the polymer I don't know, seaweed is difficult to get, stuck in the middle of Germany, I made rope from nettles brambles very strong, how water proof is this polymer long term? Thanks for great stuff you do, you give me info I have been wishing for, that I can understand, get me home sick for UK.
Wow. nice.. i have a project to make it too. but i use kappa carageenan with maltodextrin crosslink. the final product is a hard capsule shell. however, has not formed as expected. Instead, it forms 2 phases, the karatene settles and cannot be printed. do you think the problem is with the carrageenan brand or in the structure of the two materials?
Add two tablespoons of baking soda and a half of cup of elmer's glue and the whole thing will become fireproof and if you put carbon powder in it, then it will become conductive and fireproof. I have actually done this with great results.
IBM lifted the veil this week on a new battery for EVs, consumer devices, and electric grid storage that it says could be built from minerals and compounds found in seawater. (By contrast, many present-day batteries must source precious minerals like cobalt from dangerous and exploitative political regimes.) The battery is also touted as being non-flammable and able to recharge 80 percent of its capacity in five minutes.
I maybe going to the coast on Wednesday. Time to do a little research on the properties and Google seaweed. Felixstowe here we come. Maybe an alternative to rubber to seal a hho generator? I wonder
How about small metal capsules releasing enzymes directly into the material to help with digestion? Rusting can take years. Producing those might be a bit of a problem, but you might use metal coatings of soft bioplastic capsules. Like those garlic pills..
You are supposed to be able to make plastic from hemp. Do you have any clues as to the recipe for that? There's not a lot of seaweed in inland USA lol, but there is a lot of hemp.
You should support the quest for knowledge for a near snippet at 4.99 a month... you know I would have wasted a fortune buying all the bits i potentialy needed to do the exploration and inquary work stripping down junk rather than just the end build builds(knowing what to find inside stuff).... as far as I'm concerned i have opensource outsourced a proportion of my R&D... and its costing me a fraction of buying into or supporting the work privately. It better than wikipedia *who I should also gove money too
I am using Sargassum seaweed, which is another type of brown seaweed in the same proportion as suggested by the video. However, it is not forming a film, and the water is evaporating leaving a powdery residue behind. Any thoughts to make it work?
Using hemp seeds to extract the hemicelluloses Xylan xyloglucan pectin glycerin using acidic alcohol you might get the results your looking for usable biodegradable plastic Otherwise Using hemp Shiv (woody) and gasification reduce to biochar Using collected rain water leach the potassium hydroxide from the biochar using the KOH @ 1-10 part to remove the glycerin from cold press Hemp seed oil (Ballance is organic diesel) It will fix flexibility
You could pop it between to sheets of grease proof paper and use an old clothes ringer(or as we in Glasgow call it a" old mangle) that would give you a more even spread to make your sheets
if we can solder to your amazing Graphene ink, how can we weld to some bioplastic? Would you go ceramic insulating spacer bolted on (TIG etc) or refine into a glue gun type filament? ++Graphene!
have you heard of cold spray? apply metal to plastic or plastic to metal with micro particles exiting the applicator in supersonic flow of expanding gases. russian military invention.
Hi Robert. Love these videos. With your chemistry background and love for bioplastics, have you ever made celluloid? From my understanding you take flash cotton (gun cotton), which there are videos on youtube how to make that. You added denatured alcohol as a solvent to the cotton. Once it has rehardened you make it a powder and add powdered camphor. Lastly, you take a heated press like you used for your other bioplastics and you have a block of celluloid. For it being the first plastic invented it seems like there is a lack of material on it's manufacturing process. However, with you being a chemist I was wondering if you have ever experimented with it.
@@Barskor1 Haha, yes indeed. Overtime camphor will also work out of the matrix and make them susceptible for igniting. But, can you really blame a bioplastic for wanting to go out in a "blaze of glory"?

I guess the question to ask is why aren't we making this kind of stuff more often and in large quantities. Common materials, minimum time and effort. Wouldn't take much to industrialize production.
Very interesting video. I see many have commented on using it as a filament for printing. This is a great idea because a lot of messed up priting goes to waste. I wonder also about the strength of it and maybe if it can be made for auto parts.
there is work to do on it mate and work is being done so have a read around first. It's good people are thinking and of course 3d printing comes to mind but it would probably make more of a difference is we looked at things like disposable spoons, forks,knives,cups etc
@@ThinkingandTinkering agree wholeheartedly because that is where a lot of throw away plastics come from. Would be great to see them easily biodegradable.
in this form it is solvable mate - this is the basic recipe you would have to play with it to make it insoluble - but if you do that it will cease to be as biodegradable - over coating to with a varnish would be an easy answer
Hi Robert, really interesting video, thanks for uploading! I have a bit of a story and a couple of questions... I want to build an earthship (I'm assuming you know what that is, if not it's worth looking up) as my home but current uk legislation prevents anyone living in one because of the use of car tyres. The specific building regulation is to do with the fact that the tyres have been designated as a waste product and therefore not fit for purpose in construction. So it occurred to me a year or so ago about potentially using a bio plastic and casting tyre like moulds to house the rammed earth. My questions are, is this kind of plastic suitable for that kind of construction, in terms of durability, longevity and insulatory properties?
I know starch is what makes the polymer, what is the function of seaweed in this mix? does it only add a fiber to make the plastic stronger? can I use any type of weed or grass or is seaweed a must have ingredient? I don't live near a sea, so I want to know if there is an alternative to the seaweed ingredient.
why - it is already farmed on a massive scale - plus what would you rather have? the oceans full of plastics? I don't know mate - you have to do something and sure there is an impact to everything - it's really about minimising impact not avoiding it
@@ThinkingandTinkering Good point! but how fast can seaweed be replaced and what impact will it have on coastal life that needs it? Maybe a land based substitute would be better or weed grown in ponds.
They used to use hemp, but the war on drugs forced a shift to wood pulp. I think they called it "paper" and fiberboard. ... not a thermoplastic, but easily recycled
@@technosaurus3805 ......hemp fibre was crucial in the days of sailing ships and was a strategic resource . There does exist the non active hemp plant among the various types .
this is like what Henry ford was making the car panels with in 1930 more or less, hemp bio plastic that didn't corrode and were semi-flexible body panels, durable and strong.

Technically this plastic should be edible, gross, but edible.

Isnt this just a starch based bioplastic? What does the seaweed do?
I guess the question to ask is why aren't we making this kind of stuff more often and in large quantities. Common materials, minimum time and effort. Wouldn't take much to industrialize production.
But then what would we do with all the petroleum?.... :)
no it wouldn't - but quite a few folks would never use it because it isn't perfect.
Indeed. Then again, nothing ever is truly perfect. At least not for everything. I'm sure this will have a use that it is perfect for.
Very interesting video. I see many have commented on using it as a filament for printing. This is a great idea because a lot of messed up priting goes to waste. I wonder also about the strength of it and maybe if it can be made for auto parts.
there is work to do on it mate and work is being done so have a read around first. It's good people are thinking and of course 3d printing comes to mind but it would probably make more of a difference is we looked at things like disposable spoons, forks,knives,cups etc
@@ThinkingandTinkering agree wholeheartedly because that is where a lot of throw away plastics come from. Would be great to see them easily biodegradable.
For 3D printing, we need to know how to convert wasted plastic into seaweed!
@@Graham_Wideman lmao
Has anyone tried this with Kelp Powder?
Can we used for paper coating
i think i can see some lathe material coming up..Thanks very much for this.
You bet
Wound dressings !
for sure
Well disposal would still need to be careful but it will rot away or burn cleanly and that is good.
How to remove the fishy odor?
Does this only work with seaweed or could you use other biomass?
Will it dissolve in water once you dried it?
yes
Can I ask, how long did this take to set and harden?
wondering if this dissolve in water
i wonder how it handles uv / direct sunlight. if it goes brittle like abs plastic.
dunno
I wonder how many people accidentally made bioplastic in the kitchen, while just trying to make gravy for dinner.
lol
perfect to make drinking straws.
that would be a good one
What is the melting point of this plastic?
Can i replace seaweed with algae?
Would this skin a canoe or is it soluble in water? Sushi wrap?:)
Test it.
in this form it is solvable mate - this is the basic recipe you would have to play with it to make it insoluble - but if you do that it will cease to be as biodegradable - over coating to with a varnish would be an easy answer
Hi Robert, really interesting video, thanks for uploading! I have a bit of a story and a couple of questions...
I want to build an earthship (I'm assuming you know what that is, if not it's worth looking up) as my home but current uk legislation prevents anyone living in one because of the use of car tyres. The specific building regulation is to do with the fact that the tyres have been designated as a waste product and therefore not fit for purpose in construction. So it occurred to me a year or so ago about potentially using a bio plastic and casting tyre like moulds to house the rammed earth.
My questions are, is this kind of plastic suitable for that kind of construction, in terms of durability, longevity and insulatory properties?
Brilliant.
Could it be used as casing for the printed batteries?
Good question.
not this version mate no
@@ThinkingandTinkering ok buddy. Have you found any that have potential for this application?
I know starch is what makes the polymer, what is the function of seaweed in this mix? does it only add a fiber to make the plastic stronger? can I use any type of weed or grass or is seaweed a must have ingredient? I don't live near a sea, so I want to know if there is an alternative to the seaweed ingredient.
Would try this with cattail starch? The possiblibly usefull whimsy of making plastic from %100 foraged materials gave me a bit of a giggle.
do it mate lol
Now I'm worried about all the coastal seaweed.
Why?
why - it is already farmed on a massive scale - plus what would you rather have? the oceans full of plastics? I don't know mate - you have to do something and sure there is an impact to everything - it's really about minimising impact not avoiding it
@@ThinkingandTinkering Yes indeed.
@@ThinkingandTinkering Good point! but how fast can seaweed be replaced and what impact will it have on coastal life that needs it? Maybe a land based substitute would be better or weed grown in ponds.
can also add gelatine to it as well
Interesting
cheers mate
Hi, is the plastic that you made there biodegradable? Biodegradable meaning, if I bury it in the ground, would it break down?
Yes, of course, they will. Multiple research has proven that seaweed-based bioplastics easily degrade compared to plastic straws.
so make a printed circuit board, or even a separator for a capacitor.
Or just throw a handful of Graphite in for a new solar cell or collector plate. We know that where he's heading with it lol
lol - I am an open book lol
or you could
@@ThinkingandTinkering I've been watching you for a long time now.
Hello, is it edible?
Living on the prairies, I wonder if another plant would work? Quick! To the Gofer Lab!
They used to use hemp, but the war on drugs forced a shift to wood pulp.
I think they called it "paper" and fiberboard.
... not a thermoplastic, but easily recycled
@@technosaurus3805 I live in Canada, so hemp is a lot easier to get. thank you. It now gives me a starting point.
@@technosaurus3805 ......hemp fibre was crucial in the days of sailing ships and was a strategic resource . There does exist the non active hemp plant among the various types .
they use seaweed as a mulch mate - you could probably get kilos in a farm store
@@ThinkingandTinkering Yes I always get seaweed for the garden.
But then I'm only a mile from the shore.
this is like what Henry ford was making the car panels with in 1930 more or less, hemp bio plastic that didn't corrode and were semi-flexible body panels, durable and strong.
🤯
I live on the Salish Sea in Washington State. I can't wait to see what our various local macroalgae can produce.
