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!
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.
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!
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
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
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?
Ok, here is the idea from what I have seen from your other video with hemp plastic - it contracts and in line with your channel what I thought of is - battery enclosure. You leave it wet, take your carbon batteries, stuff them in, wait until everything is dry and voila - all carbon battery with all carbon enclosure. That is pretty much safe (depending on electrolyte) to recycle in to a battery by blending it :D
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?
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..
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.
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
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.
great video! what can you do to treat the shrinkage from the sides if needs to cover a certain area? also, what would you do to prevent spoilage of the wrap itself if used as food packaging (maybe even more relevant for casein film)?
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.
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"?
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!
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?
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
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.
Hi Robert have you seen the scitech daily article on laser etched aluminium making desalination /purification of water .Rochester uni I think sounds like a job for your talents, excellent content as always !
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?
very cool, though seaweed of any variety is a little scarce in the scorching deserts of west texas. in town there would be lawn grass clippings available, & in the fall leaves shed from the trees in town. would those likely provide acceptable raw materials?
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?
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!
Could this recipe work with green seaweeds such as sea lettuce? Sea lettuce grows in abundance on our beaches over the summer but my experiments so far have yielded a soft, tearable rubbery end product.
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?
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 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?
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?
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.
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 .
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 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.
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
Is adding starch a requirement? I've been adding only glycerine to the mixture to add some flexibility to it. Was wondering about the use of starch in the mixture
I am looking to make this, and I was wondering if you had any recommendations for where to purchase the seaweed from (I don’t live near a body of water where I could collect it from myself)?
Just done a little googling because I couldn't understand why seaweed would do that :-) I think from what I read it is the 'Polyhydroxyalkanoates' in the seaweed that creates a sort of polymer, the wiki page says it is UV resistant, which is a huge surprise for me. I don't understand though what the starches role is, is it just to bulk it up? May need to commandeer the kitchen for a an experiment (the wife is not going to like that) as I think that potato starch should probably work too, also I am quite interested in finding out acid resistance, specifically for isolators for capacitors.
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
sir how are you i want to learn how starch based film blowing granules are made please reply or make video on it we are interested in making starch granules for film blowing
Interesting to see how well this prints in my 3 D printer. I have a filament making machine so I'll try this out.

I just added a similar comment but don't have a filament making machine. Could be an interesting follow up video.
go for it mate - but this is a basic form - you will want to add a bit of glycerol

Robert Murray-Smith so how to disolve and cross polymer?
So awesome!!!!!!
I am thinking becoming a paying member
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 would certainly appreciate it mate
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.
Can we use coconut shell powder to make it stronger n insulating
What did you do to get it to dry? If air dried then how long did it take? If oven dried, what were the settings you used?
Thank you!❤
Hi, I’m doing a university project on this. Any way I can get it touch with you?
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
Great suggestion!
Is adding starch a requirement? I've been adding only glycerine to the mixture to add some flexibility to it. Was wondering about the use of starch in the mixture
I am looking to make this, and I was wondering if you had any recommendations for where to purchase the seaweed from (I don’t live near a body of water where I could collect it from myself)?
Can we used for paper coating
Can I ask, how long did this take to set and harden?
Can you teach us how to make glycerol at home? I tried to make it with sunflower oil and lye but did not succeed ...
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.
Thank you so much
What types of plastic could you produce from the bioresourse-seaweed?
Is there a way to make it a little bit
waterproof ?
Thank you sir.
Most welcome
I might have missed this past, but what is the name of the seaweed and just why seaweed anyway? What do special about seaweed?
how many days did you dry the seaweed? thank you
Just done a little googling because I couldn't understand why seaweed would do that :-) I think from what I read it is the 'Polyhydroxyalkanoates' in the seaweed that creates a sort of polymer, the wiki page says it is UV resistant, which is a huge surprise for me. I don't understand though what the starches role is, is it just to bulk it up? May need to commandeer the kitchen for a an experiment (the wife is not going to like that) as I think that potato starch should probably work too, also I am quite interested in finding out acid resistance, specifically for isolators for capacitors.
they are all basically polysaccharides mate - it's not so much a polymerisation as much as cross linking
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
Take a look at Psyllium Husk, it's a good gelatinizer
could the supermarket nori seaweed wrap seaweed be used to make this?
sir how are you i want to learn how starch based film blowing granules are made please reply or make video on it we are interested in making starch granules for film blowing
You’re amazing thank you
Would this work with Sargassum seaweed?
awesome as always
Thank you! Cheers!
LEGEND!!!! You rock Robert!
lol - cheers mate
can also add gelatine to it as well
Interesting
cheers mate
Can I use another kind of algae? For instance sea grapes or a green algae?
Will it dissolve in water once you dried it?
yes
When Robert Murray-Smith crosses over with Delia Smith
lol
