Potential of Bioplastic / Starch as Bioplastic

초록

SDGs : Climate action, Life below water, Life on land

Plastic is a problem that seems to be unsolvable. There are many things that are invented that were made from plastics. Including to these inventions are some plastics that tend to be used by people just once. This results to pollution caused by this plastic waste given the fact that it takes a thousand years or more for a single plastic be decomposed. Surely, using plastics is a part of most of people’s daily lives. If we cannot eliminate the use of plastics, we can have an alternative to it. This study aims to provide a prototype proposal on making bioplastics. This study will provide alternative materials for us to make bioplastics that can be decomposed faster than the plastics that we are used to. By this, the proponent aims to provide awareness and influence to help save the environment.

    Hi, I’m Minsuh from team Verde. Your presentation and report about bioplastic were very impressive. I have a few questions about your presentation.
    Is bioplastic strong enough compared to petroleum-based plastic? Also, do you have any specific examples of strict implementations of bioplastic other than changing from synthetic plastic to bioplastic in the factories?

      The durability of the bioplastics made from starch will vary. The thickness and the usage of the product will contribute to is actual durability. For an instance if the bioplastic that will be produced was very thin (just like the plastic bags when we buy in the public market), then the solubility, biodegradability and durability of it would be affected. Same goes if the bioplastic that will be produced was thick (used as a furniture, storage box and such) the durability, solubility and durability will then be changed again. Also, since we are after the biodegradability of the plastic, we all know that one characteristic of being biodegradable is that it can be easily broken down. One contributor of this breaking down process is the solvent. Imagine, if we will start using biodegradable plastics in our furniture, and we will not protect them from solvents such as water, the durability will be put into risks. So it is just a matter of care. Care for the future actual things made from bioplastics as we take care of our environment.

      For the second question, if the world will then adapt this prototype, the rules will then change. Governments should put their support on this advocacy and make it a law that no one should ever use synthetic plastics anymore so people’s mind will be open and get used to using the bioplastics.

    Hi, I’m WonJune from team Lumiere. Your presentation really impressed me since bioplastic is a research that I’m interested in. I agree that plastic is a huge threat towards human beings and the environment. I’d like to ask a few questions.
    1. Plastic is consisted of several categories, such as PET, HDPE, etc.. What categories of plastic should be replaced immediately? And what methods of bioplastic can replace them?
    2. Since bioplastic is usually extracted from materials from nature(eg-milk, corn, etc…), it is quite expensive to make them. Is it more efficient to make bioplastic than making new materials or replacing with others?(wood, glass, etc…)?
    I look forward to your great apply.

      Hi this is Isu. Thank you for your questions and here are the answers from me about your questions.

      For the first question we should change the HDPE plastics first since that type of plastic is the most versatile so it is the most used type. It can be present on the simplest things like plastic bags when we went buying something in a market, plastic bottles, shampoo bottles, so they are also present all over the environment as trashes. There are so many things that we can do with HDPE but we should focus first on the things that people “use and throw” than the things that we actually store at home and use just like some furniture and storages. Still, extraction, drying, molding will be the method for this.
      For the second question this study aims to help the environment on the most feasible way. And being it more expensive is not even on the imagination of this prototype. We can actually have partnership on some areas of the economy and environment . Just to give you a brief insight of the possible plan about it, we can extract starch from rice water without the rice being into waste. If the world will embrace this and make it a reality, we can think of more ways and connections on how we are going to make bioplastics from raw and renewable resources without those things adding up into trash.

      Thank you

    Hi, I’m Seojin Baek from Group 2. Thank you for sharing your presentation, it was very interesting and informative. I would like to ask some questions:

    1. Although bioplastics are biodegradable, they often end up in the landfills and may release methane because they are not discarded properly. Then do you think it is still better to use bioplastics instead of normal plastics? How can we dispose of bioplastics without causing much harm to the environment?
    2. Do you think using bioplastics is more eco-friendly than recycling the currently existing plastics?

      Hello this is Isu. Thank you for the questions and here are the answers to it.

      1. I do agree that if bioplastic undergo anaerobic decomposition, it will release methane and still cause harm to the the environment especially to Earth’s atmosphere. But as mentioned on you question, this just happened if it will not be disposed properly. If the world will then change in to being bioplastic user, then all of us must be so responsible and even the government should make laws about it so together we are going to save the Earth. So to solve this, all of us must know how to perform proper composting. Home composting will be the basic one that everyone can do (ideally we should compost at 82F degrees). And there is also industrial composting for a higher mass of bioplastics. They can do that as a regular compose or they can make it into biogas plant to form renewable energy.

      2. For me it is still more eco-friendly since it has been forever for the campaign of recycling the current existing plastics but still the waste is not being decreased. Since bioplastic is biodegradable in its components, with the proper use and disposal we can have a cleaner Earth. The Earth will be filled by petroleum based plastics in no time if we continue to make it and make use of it. if we are after the recycling then the world must immediately stop producing new plastics and just use what we have now in present and those will the only amount to be recycled. if this wont be possible then bioplastic will still be more eco-friendly.

    Hello! I am Hwayeon Ko, and I wrote about poverty eradication in Group 1. Thank you for your presentation and your paper. I really had the chance to learn about the advantages of bioplastic, and how it could positively affect our environment in the future. However, there are some questions that I would still like to ask you. Are many governments and the people aware of the pros of bioplastic? Are bioplastics used in any countries right now? What are some other factors that hinder governments from promoting the use of bioplastics?

      Hello this is Isu. Thank you for your question and here are the answers I’ve prepared for your questions.

      Bioplastics are actually known nowadays, it is not just being discussed and being marketed fully. And yes there are countries that are actually using the bioplastics, these plastics are mainly made of plants and materials from plants too. As I observe the world we are living, governments do promote the use of it, it is not just being focused more. And the world is not being transformed fully into being petroleum-based plastic free because the world is not stopping to produce new sets of bad plastics. Thank you.

    Hello. My name is Seoyoon Huh and I am participating for Group 4.
    First of all, I was glad you talked about bioplastic! I believe that it would become a great renewable resource that can benefit future prospects and the environment.
    A few questions, though. I have searched about the problems correlated to bioplastic (just as a little research) and found out that an increase in bioplastic may lead to food competitions. A you know, food is often considered more important than developing technology. If the people are against in creating more bioplastic due to the food crisis, how would you solve this problem? Also, it seems like bioplastic would take some time to fully develop and become used worldwide. How would you save the environment during the time in between? Again, thank you so much for sharing your opinion! It was a joy reading your essay.

      Hello this is Isu. Thank you for yourq To answer your first question, the prototype I presented do not suggest any food wastage. Let me give you a sample situation. The seed of a mango contains starch too, it is not necessary for us to waste the whole fruit but we just need seeds, technically, we are going to use some of we can refered as “food waste” too. If the world will embrace this prototype, we can further develop connections, connection of the food industry and connection of the bioplastic factories.

      To save the environment before the bioplastic will be fully embraced, the world must stop, fully stop on creating petroleum based plastics. And we will just use the plastics present nowadays through recycling and reusing. Since this will be hard, we can now see the potential of biodegradable plastics.

    Hello Isu! This is Seoyun from TAT. Your presentation and the report were both very remarkable though I have some questions for it.
    Q. As you mentioned about the steps to make starch at home, is that the one already existing or did you devised the process itself? Furthermore, do you think that starch could serve as stable bioplastic?

      Hi this is Isu here is the reply to your question.

      The extraction of the starch is actually the easiest way that is already present on our world and we are actually practicing it without even noticing it, for an instance, when we wash the rice before cooking. For your second question, I think you are asking about the durability, well the answer would be yes, most especially when it would be used with proper care too.
