Another point you never mentioned, is that the amount of land required to grow bio-plastics to replace oil based plastic consumption is enormous and unrealistic. Therefore the best option is for us to just reduce our plastic consumption at the end of the day.
@@mattiabe2598 yes even paper bags are awful. There needs to be more incentive for people to bring their own packaging where possible especially in groceries.
Also, as with the economics of Ethanol from corn, it's just oil with extra steps. All those corn fields are dependent on fertilizer (from oil) and pesticides (from oil) and harvested using tractors (with oil)
You don't need to reduce consumpion. Plastic is recyclabe, you can even make fuel out of it. Just don't throw it to the nature, recycle and there is no problem. This is more eco friendly than bioflastics or biofuels. Just remind yourself how plastic bags where brought to the market. They were and still are ecological alternative for paper and textile bags which are higly dependent on land.
agreed. also it is a question of ethics. is it okay to use up potential food for a single-use product, while many people die because there is no food? :/
This is the kind of videos that left me something that I'll never forget Another thing that i thing it's worth to mention and its scaring me, is that the materials used to make plastics, biofuels, etcs, looks pretty friendly but are in fact comestibles goods. We are feeding machines with them instead peoples. David: You already done a great positive footprint in this world. Thank you man!
The "Food versus Fuel" arguement (And a less mentioned, but equally relevant "Farmland vs Wildlife" arguement, as arable land is less of an issue compared to how we get that land in my opinion) is VERY valid, so it is good you recognize that. However there are many methods for Biological Feedstocks other than using dedicated "Energy Crops",Such as Maize or Sugarcane based ethanol/plastic, or oil crops such as Oil Palm. Mainly Algae, Argicultural Waste, Sewage/Wastewater, Food Processing Waste, and usage of "Cover crops" or other related yield increasing crops alongside food crops.

Great video Dave on a much needed topic, since the development of bio-based materials is so hindered by the misinformation from industrial that led everyone to be confused about biodegradable, bio, compostable, even organic... One drawback you didn't mention is that the plants used to make plastic are actually plants that don't end up feeding people ! This encourages deforestation, plus corn and soy (main bioplastic providers) need gigantic quantities of water to be grown. The key, indeed, seems to be in the bio-wastes that are already produced by other processes ! Keep up the great work and thanks for bringing a different view into design and society !
I just ADORE Dave! I am so interested in everything you and Precious Plastics team(s) are doing. What a great service to us all. I'm one of your Pateron supporters and I'm always so happy to see anything you have to share. About the title, I think one of the other commenters is just about right but I would change the title to: The Truth about Compostable Plastic and How to (dis)Solve It.
Thank you so much for a clear, engaging thought through video explaining this! I have been frustrated of being given food in bio-plastic containers at work which say ‘industrially compostable’ on them, which sounds great but when we only have landfill bin (& occasionally a recycling bin) to put them in it seems completely pointless and wasted. Yet I believe that the companies I work with feel like they are ‘doing a good and right thing’ by using them. But without the correct waste stream it is in effect making things worse.
Thanks for another great video! I am currently planning opening a mix workspace in Kyrgyzstan, just wanted to let you know that your work and efforts are very much appreciated.
Great stuff! Enjoyed that! The one thing you didn't mention is many bioplastics are also recyclable. PLA in particular is recyclable. The biggest problem is maintaining purity through the recycling process, which fits your point about segregation of waste. So does the fact that bioplastics that are buried in landfill, emit methane. Which is bad for the environment and even creates an explosion risk. Which is probably why you were not allowed into the composting unit. Segregation of plastics is definitely a problem I think we need to solve.
Good thing you mentioned biodegradable plastics at the end. Because I have worked on PHA and was thinking about it during the whole time haha. PHA is produced naturally by bacteria and they degrade it too. So you can just drop PHA plastics anywhere in soil, they'll decompose in a few weeks. Would have been nice if you has done a video using that.
New video! Yay! That's the experiment which I have had in my mind for quite long time. When I first seen the PP corn plastic cups. It just has to be to good to be true :P This video is the great source of information about it! Thank you Dave!
Cool! those pressed materials bowls remind me of the pressed and formed banana/palm leaf bowls and plates which seem to be growing in popularity as well. Thank you for putting this out there and encouraging people to experiment!
1) i don't get testing the decomposition of items by wrapping them into another plastic - then cups and all those items inside are not exposed to the environment for few weeks or even months until bag has its first hole? why not just putting them into water/soil just like that? 2) yeah, "bioplastics" and "compostable" is really gross greenwashing in plastics IMO. i hope EU gets chance to fix labels like that into something less greenwashingy and more honest 3) great job explaining things - especially how "bioplastics" introduce chaos into recycling/composting waste systems. i never thought of that myself before 4) making bowls or trays just from bran and water is incredible. i had no idea such thing would be possible OMG. gives ideas.. Very good video!! thanks guy/rls!!
+ is industrial bioplastics decomposing even feasible from energy point of view? I wonder how much energy such plant needs to run. And what is the outcome, can we re-use it again for new products or is it just dumped somewhere?
Definitely better to recycle - takes 50x the energy to compost it at one of these industrial facilities compared to just recycling into a new product 👍
I think the issue is PROPER RECYCLING AND EVENTUAL DISPOSAL Plastics are essential to hermetic seals, products that can last a long time, and yet be light and not brittle (Ie not glass or ceramic) I think they are essential to many aspects of the modern world (granted some use cases should be stopped such as "disposable" water bottles etc) I feel it is much more important to encourage proper plastic life cycles, rather than try and fear monger/ban it entirely Plastic is no issue if it is: - Reduced as Much as Possible (use less, don't have "dumb" use cases ie disposable water bottles etc) - Made from biological source material (in plants using sustainable energy sources for power) via *the chemicals made via microbes in bioreactors *Via Pyrolysis Oil (preferably from Biomass and/or RDF firing plants) *Via Biomass Oil (Via oil crops like algae, and NON FOOD VS FUEL SOURCES) *Via HTL Bio-Crude - Sorted and Recycled (As many times as possible) - Downcycled ( PET->Polyester etc) - Disposed of Properly (Prefferably via Biological Digestion (Anerobic, or via Genetically Modified "Plastic Eaters" in biodigesters), or Pyrolysis and/or Gassification)
We have the technology for most aspects of the above outlined solutions. Others are near-future, and are limited mainly by research funds, and "economic viability" both of which are solved via government action (Taxes on the bad, subsidies on the "good", regulation of pollution, research grants etc)
I think the Precious Plastic Recycling Ecosystem will have a HUGE impact on developing areas growing their recycling ability. We need to "Close the loop" however, with Renewable and Sustainable Sourcing Options, Enviromental Cleanup Workflows/Tools, and "End of Life" options. Production is more difficult short of PLA, and may thus be better left to larger entities. The continued development of sorting sensors/workflows, and the below enviromental recovery options may act as a sort of "Plastic Mining" source. Pollution Cleanup Options Such as Locally Produced "Booms" to contain, and if towed, collect Floating Plastic Debris could reduce local plastic pollution (ALONG WITH stopping ongoing pollution obiously) End of Life Options are an area Precious Plastic could expand into well; Workflows for Anerobically Digesting PLA, and Designing Low/No pollution Pyrolysis Units (Short of CO2 emmisions if using fossil fuel based plastic) could turn the "Un-recyclables" into useful energy, and prevent them from ever becoming polluting microplastics. I feel these three areas can be developed by Precious Plastic, and would lead to far more Real World Change.
Why don't people just throw the unusable plastic in a thermal reactor and crack it into plastic diesel and gasoline? the U.S. already is doing it and saving thousands by not having to buy so much oil from other counties.
Dave, very good explanation. Thanks for your work and keep it up. Especially beyond plastic (even if I do not agree with everything off precious plastic)
Hello Kamp Dave and Army, I am writing from Canada and am so awed and impressed by the common sense approach to disentangling the waste management process. Turning it into a green end result for the planet, through vision and community futures. 💡 I have an idea, not sure it will be advantageous, yet worth taking it into consideration. Using a parabolic mirror finish disc and using the sun as a solar eliminator...build an outdoor cement holding, open front-entry shelter for plastic, with a roof exhaust fan filtration using a 2 step charcoal-water purification filter system. With the sun's angled ray directed with the parabolic dish which is attached to a fabricated metal rotating stand aimed at plastic. This will reduce the plastic into recycled reusable for building material. This end product is of course mixed with sand, cement, refined parabolic-plastic and foam to create a lightweight bricks and blocks building for housing. Just a though. □♡□ Mary
what you do is really cool, I also want to do that, treat plastic waste and educate other people about the dangers of plastic to this earth. because in my country, trash is like a mountain that can explode at any time
The thing about P.L.A. is it it was designed to break down in heat and moisture combined, the reason for this is because you wouldn't want packaging breaking down while still in the store on the shelves before it is bought and used. P.L.A. was designed to be broken down in a compost pile which when done properly poses both heat and moisture for the P.L.A. to properly decompose.
Well I looked in to the standard of both of them ASTM D6400 (for compostable) and ASTM D6954 (oxo-biodegradable) you ll be suprised that they both have same biodegradbility criteria its just the way they get that stage is different compostable needs composting facility and oxo-biodegradable needs open air (basically oxygen) because these confusing mis informations yes alot of places have banned oxo-degradable. Bu i think it has potential when it comes to littering issue and mismanaged waste soley because it biodegrades in open environment
I just think it will be fun expriment to do, and of the results turns out the opposite of what the general public thinks that would be interesting as well !
cool, I'll have a look at those standarts again! As far as I understand oxo-degradable plastics work by adding things that oxidise to the plastic, which just helps to break it into smaller pieces, but that doesn't have to mean that it degrades, right? "There is a considerable risk that fragmented plastics will not fully biodegrade and a subsequent risk of an accelerated and accumulating amount of microplastics in the environment, especially the marine environment. The issue of microplastics is long acknowledged as a global problem in need of urgent action, not just in terms of clean-up of littering, but also of plastic pollution prevention." (from the wikipage of oxo-biodegradable plastics)
Yes, it can be composted. But the composting plants do not want the materials because it means that they need to change their current schemes and termperatures and such. And they say it downgrades the quality of their compost.
what an important video! thank you. but i have one question: what happens after the biodegradable plastic degrades? does it become micro-plastic, which is even worse for the soil, water...? im also wondering if it is ethnically correct to use up potential food for just a one-time product :/ and if it is really better than oil, since all that used up fields and destroyed animal life :/ you are awesome :D
I was wondering about the bio-degradable thing... (Axel Sixtysix also mentions is in a comment further above.) I have read somewhere before (wish I remembered where) that only some biodegradable plastics are actually biodegraded (meaning actually returning back into the cycle of materials in the environment) and some just break apart more easily, so are basically just mechanically reduced to more microplastics. Do you know more about this? Are there actually are any "bio-degradable" plastics at all that degrade down far enough into a molecular structure that organisms in nature can utilize again?
Hi Dave, could you please tell me, would melted HDPE adhere to concrete, for example if i was to make a river table from concrete could i use melted HDPE to replace resin, if so would it be best to create say small islands from HDPE then pour the concrete, or pour first, create holes in the concrete and then add the HDPE? awesome work in your vids btw.

Isn't "normal" plastic also "compostable" Just as "compostable plastic" isn't really. It's carbon arranged in a certain manner, be it sourced from plants and animals stored under ground turned into petrol naturally, or freshly picked bio source turned into "petrol" industrially. Calling it "compostable" is miss-leading and could cause even bigger problems.
we have to reform the weaponry into recycling machines and a AI in the background to run the processes of upcoming new ideas and new plans, for the future earth design of harmonisation! If we want stop this overgrowing waste monster then we have to work together in Europe and connect the rest of the world, then we are unstoppable!
Well there's a lot of approximations in this video. First, PLA has never been fully composted yet. There's one studdy in which scientist note THE START of a degradation, and concluding PLA might be compostable. The laboratory conditions was: warm temperature, high moisture, as Dave said, BUT he forget High pressure AND high enzyme concentration. That's why even in a composting unit, PLA is still not compostable because all the required conditions are not met. Source : hal.archives-ouvertes.fr/hal-00977105/document Second, about bio-degradable plastics. There's no hope in it, definitely, except to hide the problem. Let me explain why. What is called bio-degradable plastic are in fact programed braking polymer links. Technically, you introduce into the polymer (which can be any polymer, even the worst ones environmentally speaking) an element which will degrade in a time. Anything which can be degraded by UV, water, oxydation or mecanical solicitations. Is it any good ? Well, these bio-degradable plastics are still not assimilated in the environment. Some links are broken, and the item loose its shape, for sure, but there's plastics left. Micro-particles actually. Just you can't see it. Into the sea or live water, it's still very harmfull for any biotope.
@@hewhoisknownastaco back in 2009 I was working for a major food company at packaging dpt. This have been told to us by our bags provider. In 2009 there were no PLA bags yet, so it was degradable PE. Few years later came the PLA version, with same degradable properties. You won't find much documentation about this, because this is business. Neither about electric/hybrid/hydrogen cars, which are not much greener than gasoline cars...
Maybe the important thing to mention in reference to this video: Dave is by no means encouraging the use of any kind of plastic, quite the opposite. Becomes clear if you watch the whole video.
Can we talk about the erosive way of growing the base resources?? We don't need the plow, we don't need the tractor and most of all we don't need the wheat, corn and what not of annuals... Nature is not annual it's perennial, but that is just farmer of me! have a nice day, looking forward to the day I can eat out of a bowl that will just breakdown if I'm done with it!
Its comes back to the point #4 : A Good Marketing Strategy. More information here: www.npr.org/2020/09/11/897692090/how-big-oil-misled-the-public-into-believing-plastic-would-be-recycled This video makes me think again, about how big oil Companies and virgin plastic suppliers (like Cocacola) are looking into new marketing schemes (not necessarily new materials) to keep pumping plastic into the world without accountability as long as their marketing schemes keeps working. For example: this attitude just permeates through society : "it doesn't matter, ITS RECYCLABLE", o r maybe even "its bio-plastic.¨ Event though they call it "compostable", or whatever, it pretty sick how there are always ways and newer language to categorize the plastic. It looks like it creates more chaos on the collection part.
hahahahaha, geniaal! Gewoon serieus je kop kaal geschoren voor die eindgrap? Mocht je eens in Malaga komen dan krijg je van mij een volledig natuurlijke shampoo zonder plastic verpakking die ongetwijfeld helpt om het weer aan te laten groeien :)
You want better waste management so everything is actually recycled. More R&D to break down complex plastics using chemistry. And less single use plastic and less consumption in general, this idea of green growth is impossible on a finite planet.

Another point you never mentioned, is that the amount of land required to grow bio-plastics to replace oil based plastic consumption is enormous and unrealistic. Therefore the best option is for us to just reduce our plastic consumption at the end of the day.
Always reduce our resource consumption in all fields
@@mattiabe2598 yes even paper bags are awful. There needs to be more incentive for people to bring their own packaging where possible especially in groceries.
Also, as with the economics of Ethanol from corn, it's just oil with extra steps. All those corn fields are dependent on fertilizer (from oil) and pesticides (from oil) and harvested using tractors (with oil)
You don't need to reduce consumpion. Plastic is recyclabe, you can even make fuel out of it. Just don't throw it to the nature, recycle and there is no problem. This is more eco friendly than bioflastics or biofuels. Just remind yourself how plastic bags where brought to the market. They were and still are ecological alternative for paper and textile bags which are higly dependent on land.

The "Food versus Fuel" arguement (And a less mentioned, but equally relevant "Farmland vs Wildlife" arguement, as arable land is less of an issue compared to how we get that land in my opinion) is VERY valid, so it is good you recognize that.

- Reduced as Much as Possible (use less, don't have "dumb" use cases ie disposable water bottles etc)
- Made from biological source material (in plants using sustainable energy sources for power) via
*the chemicals made via microbes in bioreactors

Did you have a chemical composition of each product?
I was wondering about the bio-degradable thing... (Axel Sixtysix also mentions is in a comment further above.)
I have read somewhere before (wish I remembered where) that only some biodegradable plastics are actually biodegraded (meaning actually returning back into the cycle of materials in the environment) and some just break apart more easily, so are basically just mechanically reduced to more microplastics.
Do you know more about this? Are there actually are any "bio-degradable" plastics at all that degrade down far enough into a molecular structure that organisms in nature can utilize again?
What about the products from Tecnaro? Arne they Bioplastic oder biodigradebel Plastics?
I think a great material for this would be dust made from hay.
Hi Dave, could you please tell me, would melted HDPE adhere to concrete, for example if i was to make a river table from concrete could i use melted HDPE to replace resin, if so would it be best to create say small islands from HDPE then pour the concrete, or pour first, create holes in the concrete and then add the HDPE? awesome work in your vids btw.
What are the raw materials of bio plastic brother.?
You have some progress in this area of investigation???
It's true even test it with a suvee unit
Bowl press is Outstanding
Bast fiber make an extremely strong similar style glass
But until the world goes Hemp you need petroleum for modern agriculture
What about the biodegradable plastic made from kombucha? like how???
Save food save water save power save fuel save paper save trees save ozone save nature save life save Earth Stop covid viruse Stop Global Warming stop pollution control
Bring on biodegradable materials
Hey from Micronesia!! Would dehydrated banana peels work for bowls also? Thanks for the videos, Dave 🤙🏽
hi! dunno, try it out ;)
Thanks for supporting my views
Everything was fine until you took off your cap... О_о
Oh damn why you have to bring that up
13:10 Nice hair!
P.S. So sad to know that compostable plastic still is not compostable.
*bioplastic
Great
Thanks!
feel sad. how about PHA?
Its not ment to degrade in 1 year that would make the plastic useless
Is biodegradable plastic similar to plastic in a molecular point of view ?
Awesome
So now that you know what PLA is, do you want to go back and correct your 3D printing video where you said it's made out of oil?
1:09, Ah the coffee polymer tray from www.ovdesigns.nl/coffee-polymer.html. Did I bring that one to the workspace a while back? I don't remember haha
I've gotten some packages with sorghum peanuts, they dissolve in your sink!

That video Is champion's stuff. Aaaand 13:08
Isn't "normal" plastic also "compostable" Just as "compostable plastic" isn't really. It's carbon arranged in a certain manner, be it sourced from plants and animals stored under ground turned into petrol naturally, or freshly picked bio source turned into "petrol" industrially. Calling it "compostable" is miss-leading and could cause even bigger problems.
we have to reform the weaponry into recycling machines and a AI in the background to run the processes of upcoming new ideas and new plans, for the future earth design of harmonisation!
If we want stop this overgrowing waste monster then we have to work together in Europe and connect the rest of the world, then we are unstoppable!
Well there's a lot of approximations in this video. First, PLA has never been fully composted yet. There's one studdy in which scientist note THE START of a degradation, and concluding PLA might be compostable. The laboratory conditions was: warm temperature, high moisture, as Dave said, BUT he forget High pressure AND high enzyme concentration. That's why even in a composting unit, PLA is still not compostable because all the required conditions are not met. Source : hal.archives-ouvertes.fr/hal-00977105/document
Second, about bio-degradable plastics. There's no hope in it, definitely, except to hide the problem. Let me explain why. What is called bio-degradable plastic are in fact programed braking polymer links. Technically, you introduce into the polymer (which can be any polymer, even the worst ones environmentally speaking) an element which will degrade in a time. Anything which can be degraded by UV, water, oxydation or mecanical solicitations. Is it any good ? Well, these bio-degradable plastics are still not assimilated in the environment. Some links are broken, and the item loose its shape, for sure, but there's plastics left. Micro-particles actually. Just you can't see it. Into the sea or live water, it's still very harmfull for any biotope.
Do you have a reference to your claim about the biodegradable plastics? I suspect this is true as well, but I'd like to see some research.
@@hewhoisknownastaco back in 2009 I was working for a major food company at packaging dpt. This have been told to us by our bags provider. In 2009 there were no PLA bags yet, so it was degradable PE. Few years later came the PLA version, with same degradable properties. You won't find much documentation about this, because this is business. Neither about electric/hybrid/hydrogen cars, which are not much greener than gasoline cars...
Maybe the important thing to mention in reference to this video: Dave is by no means encouraging the use of any kind of plastic, quite the opposite. Becomes clear if you watch the whole video.
@@martin_mue I'm a PP supporter since the start. I guess I do not go astray about Dave or the PP team. I just share what I know.
Avoid plastic disposal things please
There is another way to biodegrade pla as long as it doesn't have additives just leave pla in 70c water for one week and it will biodegrade
6:54 what is this place, where you have peacocks? D:
Can we talk about the erosive way of growing the base resources?? We don't need the plow, we don't need the tractor and most of all we don't need the wheat, corn and what not of annuals... Nature is not annual it's perennial, but that is just farmer of me! have a nice day, looking forward to the day I can eat out of a bowl that will just breakdown if I'm done with it!
I am gonn a buy plastic
Hello subtítulos en español par favar ... I like you videos man

I knew it
Its comes back to the point #4 : A Good Marketing Strategy. More information here: www.npr.org/2020/09/11/897692090/how-big-oil-misled-the-public-into-believing-plastic-would-be-recycled
This video makes me think again, about how big oil Companies and virgin plastic suppliers (like Cocacola) are looking into new marketing schemes (not necessarily new materials) to keep pumping plastic into the world without accountability as long as their marketing schemes keeps working. For example: this attitude just permeates through society : "it doesn't matter, ITS RECYCLABLE", o r maybe even "its bio-plastic.¨ Event though they call it "compostable", or whatever, it pretty sick how there are always ways and newer language to categorize the plastic. It looks like it creates more chaos on the collection part.
I know it
La verdad de los bioplasticos degradables !
hahahahaha, geniaal! Gewoon serieus je kop kaal geschoren voor die eindgrap? Mocht je eens in Malaga komen dan krijg je van mij een volledig natuurlijke shampoo zonder plastic verpakking die ongetwijfeld helpt om het weer aan te laten groeien :)
You want better waste management so everything is actually recycled. More R&D to break down complex plastics using chemistry. And less single use plastic and less consumption in general, this idea of green growth is impossible on a finite planet.
PLA is worse than regular PET.
Hello boys
About polution i know you dont understand Polish but in Poland in many cities we have same groups it s name "uwaga śmieciarka jedzie" were you can give yours stuff to another people. I think you can inplicate this on easter europe. facebook.com/groups/Uwaga.smieciarka.jedzie/?ref=share

talks about harms of plastic but supports monocultures
It makes me feel so uncomfortable to see you guys dumping stuff
