- Bioplastics are a scam! Come learn more about it today!
Hey yall! Welcome back to my channel! We are talking about the differences between petroleum, plant, and bio-based plastics. Some of these plastics will outlive us and other are listed as biodegradable. But which ones are actually sustainable, biodegradable and less harmful? Research shows that some plastic being marketed as sustainable options actually don’t degrade as quickly as suggested in industrial or natural environments.
Here are a few examples of plastics:
• Bio-PE and Bio-PET are not biodegradable
• However Bio-PLA and PHA is listed as biodegradable
• Plant based plastics are assumed to be biodegradable
• Petroleum based plastics that are listed as biodegradable include PBS and PBAT
Learn more by watching the four facts you need to know about bioplastics vs biodegradable plastics.

What biodegradable or compostable plastics have you come across?
Polyhydroxyalkanotes is the best thing I have heard of.... otherwise bioplastics are probably worst for the environment.
At least normal common PE etc... plastics can be recycled.
This is very valuable and helpful, but I think conflates several issues. As a researcher (and dedicated trash picker-upper) looking to help rid the oceans of microplastics and reduce our overall GHG footprint, I feel it is most important to:
1. Stop the mismanagement of plastic waste. It is much better to "re-sequester" plastic in a proper landfill making it carbon neutral or negative, than to have it free in the environment.
2. Replace oil and natural gas-derived plastics with bioplastics. THEY DO NOT NEED TO BE BIODEGRADABLE. In fact, if it takes longer to biodegrade it is better. Why? Because the carbon you used to make that plastic was pulled out of the atmosphere. You only want it to go back slowly or not at all to make it carbon negative (see point 1 above). Once it biodegrades, it releases its carbon back into the atmosphere (carbon neutral). Bio-sourced plastic is carbon-negative or carbon-neutral. Petroleum-sourced plastic is carbon-neutral or carbon-positive.
3. Demand policy changes from our lawmakers that take the impossible burden off of consumers and place it on the companies and institutions that have the power to make a difference.
4. Read the recent UN report here: www.unep.org/resources/turning-off-tap-end-plastic-pollution-create-circular-economy
Well said! Thank you for engaging with the content! I’m really hoping the new plastics treaty works to address some of these issues.
Love the video! I'm trying to figure out which local restaurants have "good" carry out containers and this was very helpful!
It’s always a tough situation with take out but it’s always a win if they don’t automatically give you plastic utensils. Some places have restaurants that have returnable Togo containers which is the most ideal but it pretty rare depending on where you live.
I looked into bioplastics a bit once I encountered plastic made from sugarcane by the brand Public Goods, and wanted to know if that was actually any more sustainable. This video really increased my understanding of the whole space and all the alternatives, thank you!
I am so happy that I could help you! Thank you for checking out my video and this channel!
Great video, really inciteful and well presented!!
Glad you enjoyed it! Thanks for watching!
We need to develop the technology. It's hard for us to live the way we do without plastics. If plastics become biodegradable, compostable, and sustainable it would solve a lot of our problems. It's hard for me to think about all the plastic ending up in our oceans. That has got to stop.
Absolutely agree! We need more alternative materials for plastics and we need to build a circular economy for our plastics to prevent them from ending up in our environment. We just have to make sure we are making alternatives that are actually doing what we want them to do and make sure they are safer alternatives. And that technology development is gonna take time and an interdisciplinary team working on this.
i have read about someone in southeast asia i believe who used cassava to produce plastic, and once submerged in water it breaks down and dilutes in the water. it was years ago and i do not know why it hasn’t become a big thing right now.
btw, what did you take as a bachelor’s degree? thanks for the video. have a nice day and wishing you good health, happiness and safety, you totally deserve it:)
Hey There! I have heard of cassava as well but I haven't really seen published scientific papers on it. Might need a few more years for the technology to start growing. My bachelors degree was in Marine Science. It's pretty different from Environmental Engineering so I am thinking about also making a video on what it was like to do the big switch. Thank you for the kind words! Hope you are doing well as well!
1k subs!!!!!!!!! CONGRATS. MORE TO COME
Thank you! I can't wait to see how this channel continues to grow.
Never thought I would be interested in information about plastics. Video is so layman friendly.
I’m so happy to hear that this content is accessible for people to understand and learn from! It’s my ultimate goal to make science fun and easy. Thank you for watching!
Underrated video. Changed my perspective for awhile. Dont lose your passion if I wont😎
Thank you for the kind words! I really appreciate it!
Love to see it, gyal! Proud of you. Some of us talk about this stuff every day but I think maybe telling ppl what PLA is (or the other example i noticed Polystyrene>> Styrofoam) would help make this just a bit more "laymen-y." Anyway, high five! I have subscribed.
Thanks for sharing and subscribing!! I appreciate all tips to make the content more accessible for every audience. I have been getting quite a few questions on PLA and PHA so that may be a future video!
this video was pretty helpful..was planning to purchase some company stocks that's in this space and was trying to learn difference between PLA and PHA
Glad I could be of help! Thank you for watching!
Thanks for the video! It was a really clarifying analysis. It shows we need to approach environmental solutions from a broader and more comprehensive perspective. Everything, from the way we do agriculture to the way we consume on our daily basis, is intertwined and every change we make must take into consideration the possible ripples in the whole system.
PLA looks promising, but it needs a recylcing infrastructure and quality and safety standards we don't have right now. Besides, if we don't reduce the amount of disposable plastic needed in our economy we're not going anywhere.
Absolutely agree! This is why the burden should not fall all on the consumer to make choices. It should be policy changes and industry innovation that drives down the amount of unnecessary plastic. Thank you for watching and engaging with the content!
This was a great and informative video! Loved that you talked about the necessary degradation conditions for “degradable” plastics.
Thank you so much for watching! I think it’s super important for people really understand what some of these terms mean in the real world. We gotta do better than wishful thinking when we are designing alternatives to petroleum based plastic. Really appreciate your feedback!
I love this video! It’s so engaging!
Awe thanks! It took me a bit of time to create but it was worth it in the end! 😊
This is such a great video!
Thank you! I’m glad you like it!
I stopped buying the plastic straws, I got some metal ones, I'm thinking of taking one of my metal straws to a restaurant that I'm going to on the 21st as they use paper straws, but also let me just say that if you are going to buy a drink from somewhere like Costa Coffee or Starbucks, please take your cup with you as you won't need to throw that cup away plus you'll save more money
Those are amazing tips! And I love the metal/silicone straw idea! Glad to hear coffee shops are taking reusable cups again!
Thank you so so much for this incredibly informative video! This information is so needed and this video is so accessible! I know the most ideal answer right now is to use re-usable utensils etc but when disposables are necessary - is there an ultimate answer for now? Since traditional plastics can be recycled, is that the better option right now does anybody know? Or would something like a bamboo fork be better than all of the above options since it is a raw material thats considered sustainable? Even though that would end up in landfill? This is such an overwhelming topic so thank you for simplifying the details for us! I am so grateful! You're amazing!!
Hey Kate! The scientific community is currently urging people to reduce their use of all single use plastics (bio and petroleum based) and go reusable as much as possible. They are still doing life cycle analysis to weigh which items have better substitutes overall. You can learn more about the United Nations studies here www.lifecycleinitiative.org/activities/key-programme-areas/technical-policy-advice/single-use-plastic-products-studies/
I use eye drops contained in single use plastic pipette shaped containers. Everywhere I look I see plastic containers, plastic products, or plastic packaging and feel intensely sad.
It’s really hard for the average consumer to avoid single use plastic. That is why the responsibility to reduce plastic waste should primarily lie on producers.
Unfortunately I have to use eye drops in single vials too.
How do I detox the plastic from my organs?
Have you heard or done research on claims made by Danimer Scientific about their pha plastics that are supposed to be water degradable and home compostable?
I actually haven’t but I will definitely look into it! It definitely helps if they have a peer reviewed research papers to prove it. Thank you for sharing!
@@imariwalker Hi, unfortunately I don't have access to journal databases anymore, and there's nothing I can see besides press releases.
I bought these garbage bags off of Amazon, because so many people were complaining in the reviews that it started to break down on them and leak. www.amazon.com/dp/B077ZK4XZ7/ref=cm_sw_em_r_mt_dp_X36DFbV1W3DPK So I figured it would be a safe bet they would break down pretty quickly in the landfill.
Thanks for sharing! I will definitely check these out!
Don't bury them, leave them exposed to sunlight and UV. They will break down.
UV light won’t always help if it causes the chemicals in the plastic to become something more toxic. 🫣 but it will increase the degradation rate
whats the difference between PHA and PLA?
Both plastics have different starting materials and different polymer chain structures. They will also likely have different combinations of polymer additives to enhance the material. Here is an article that may help some more on the differences www.sciencedirect.com/science/article/pii/B9780128196618000081
Thank u for this pretty and smart lady
Thank you for watching
9:05 Bio plastics can be just as toxic. Just what I wanted to know.
Happy to help!
Environmental engineering safe 🌎
Hopefully so! Thanks for watching!
💕
Thank you!
