Bioplastic from Waste Author s: But this is a stovetop bioplastic, so I had to follow the instructions and dry it. Even banana skins have food value as they are fed to pigs in some places. Because bioplastics are fairly new, this created room for further development. The smell of banana peel smoothie as it simmers is surprisingly good. Next comes the bit that always makes my heart sink a little: The thyme is there as an anitfungal agent, something that I think is a highly desirable component: Now, what are reseagch going to do with it?
The researhc part of the process was the moment when I got my first successful result. Elif conducted 12 experiments, with the first 10 ending in failures.

Stay In The Know! Everything goes in a saucepan and is mixed together over a medium heat. Elif hopes that the use of bio-plastic will be used to replace some of the petroleum-based plastics in use today for such applications as insulation for electrical cables and for cosmetic prosthesis. On the day that I made bioplastic, I put at least three plastic bottles in the recycling bin.
When the time was up I strained it, and pressed out as much water as possible. I turned them over and gave them another twenty minutes, then switched off the oven and left them in overnight. No doubt some efficiencies could be found if this were being made into an industrial process. Pollution was greatly affecting Istanbul, with plastic being a huge culprit.

Kanoria Mahila MahavidyalayaJaipur, Rajasthan Arivuo li Dakshinamoort hy. Currently pollution due to plastic is a crisis threatening worldwide. Due to environmental concern, our society is facing an emergency to find a replacement to conventional plastics. Thereby, bioplastic is a suitable option, as they can be synthesized from various waste supplements. Bioplastic are plastics formed from the renewable biomass composed of biopolymers, starch, cellulose and a variety of other sources.
They have the ability to degrade easily as compared to normal plastics formed from non-renewable sources which will not be degraded easily causing environment pollution.
The current work aims at preparation of bioplastic sheet using different varieties of banana peels.
Sixteen-Year-Old Student Turns Banana Peels Into Bioplastic
Waste banana peels serve as organic material with abundant availability, cost efficient and environment friendly properties. Making bioplastic from banana peel instead of petroleum based plastic is an effective solution leading to reduction in use of non-renewable raw materials. The main component of the banana peel is starch. From various studies it was confirmed that starch is present more in raw green variety when compared to the mature fruit banana peel.
The work included the combination of two biopolymer corn starch and peel starch in the development of bioplastic film. The banana peels are amalgamated with glycerol as plasticizer. Starch behave as a thermoplastic in the presence of plasticizer. This research work is completed in two steps, first step is levigation of banana peels with unique concentration of different chemicals.
The prepared sheets where to be tested for its chemical interaction with various materials with FTIR, its transparency using UV Spectrophotometer, its crystalline nature using XRD and few degradation studies to confirm its stability and period of degradation. Keywords : glycerol, French plantain, sevvazhai, robusta, corn starch, degradation.
Plastic is a synthetically made polymeric material. It is made by polymerization of complex organic materials and can be moulded into various forms or film, can be pressed into thin filaments or fibres by the application of heat and pressure.
As formed of crossed-linked monomeric units, this provides polymers rigidity and thermal stability. In plastic packaging, plastic polymers PVC and polyethylene of higher density and low density polyethylene are used commonly Noor et al The usage of plastic is wide enough in all our daily use such as food packaging, school, office, automotive, communication, transportation, pharmaceuticals, household materials, lamination, packing of materials and many other fields due to its advantage of being flexible, transparent, low weight, cost efficient, thermal and chemical stability, solar radiant, insulating properties and resistant to microbial degradation Sofiah et al Today most of the available plastic is synthetically produced from basic raw materials, crude oil and natural gas and several other chemicals serve as starting materials for manufacture of various plastics Kalia et al World-wide over million tons of petroleum based polymers are produced every year and used in manufacture of plastics and its derivatives from raw materials natural gas, crude oil, and coal Barry What comes to mind before you discard your banana peel?
Certainly not the consideration of its use to reduce petroleum-based pollution and create bio-plastic, yet this is exactly what Elif Bilgin, 18, from Istanbul, Turkey, sought to achieve and successfully accomplished. A motivated and compassionate scientist, Elif was driven to find an alternative from petroleum produced plastics to benefit the environment. In her journal she mentions that Thailand discards tons of banana peels per day, therefore the starch and cellulose so important for plastic production could be put to much better use.
From her research she discovered that potatoes and mango peels are already commonly used, therefore in Koc High School, Turkey, she began experimenting. Over the period of four years, her trials using banana peels many times ended with disappointment; 10 failed experiments that created plastics not strong enough or too easily decayed did not slow her down, however. Her persistence resulted in triumph with her last two trials, both creating plastics that had features she sought.
Elif hopes that the use of bio-plastic will be used to replace some of the petroleum-based plastics in use today for such applications as insulation for electrical cables and for cosmetic prosthesis. Hoping to attend medical school someday, her future holds many bright achievements to be sure. Brilliant minds of a variety of ages continue to discover alternative methods for sustainable energy; the one question is, who will now apply these practical findings?
Science America Review. Skip to content. Good Deed.Bioplastics are plastics derived from renewable biomass sources, such as vegetable fats and oils, corn starch, pea starch or microbiota. Common plastics, such as fossil-fuel plastics, are derived from petroleum; these plastics rely more on fossil fuels and produce more greenhouse gas.
Some, but not all, bioplastics are designed to biodegrade. Biodegradable bioplastics can break down in either anaerobic or aerobic environments, depending on how they are manufactured. There is a variety of materials that bioplastics can be composed of, including: starches, cellulose, or other biopolymers. Some common applications of bioplastics are packaging materials, dining utensils, food packaging, and insulation. Constituting about 50 percent of the bioplastics market, thermoplastic starch, currently represents the most widely used bioplastic.
Pure starch possesses the characteristic of being able to absorb humidity, and is thus being used for the production of drug capsules in the pharmaceutical sector. Flexibiliser and plasticiser such as sorbitol and glycerine are added so the starch can also be processed thermo-plastically. By varying the amounts of these additives, the characteristic of the material can be tailored to specific needs also called "thermo-plastical starch".
Simple starch plastic can be made at home. Industrially, starch-based bioplastics are often blended with biodegradable polyesters.
These blends remain compostables. These blends are no longer biodegradables, but display a lower carbon footprint compared to the corresponding petroleum-based plastics. Cellulose bioplastics are mainly the cellulose esters, including cellulose acetate and nitrocellulose and their derivatives, including celluloid.
Genetic modification GM is also a challenge for the bioplastics industry. Looking further ahead, some of the second generation bioplastics manufacturing technologies under development employ the "plant factory" model, using genetically modified crops or genetically modified bacteria to optimise efficiency.
The environmental impact of bioplastics is often debated, as there are many different metrics for "greeness" e. The debate is also complicated by the fact that many different types of bioplastics exist, each with different environmental strengths and weaknesses, so not all bioplastics can be treated as equal.
While production of most bioplastics results in reduced carbon dioxide emissions compared to traditional alternatives, there are some real concerns that the creation of a global bioeconomy could contribute to an accelerated rate of deforestation if not managed effectively.
There are associated concerns over the impact on water supply and soil erosion. At one time bioplastics were too expensive for consideration as a replacement for petroleum-based plastics.
The lower temperatures needed to process bioplastics and the more stable supply of biomass combined with the increasing cost of crude oil make bioplastics' prices more competitive with regular plastics. See also: Bioplastic. The strength of the bioplastic was determined by applying a 4N pulling force on the plastic from the opposite sides of the plastic plate in order to determine whether the plastic broke.

Repeat Famous Experiments and Inventions.The banana peel is something we throw away every day, but little do we know, it has much more efficient uses.
For example, in Thailand, tons of banana peels are thrown away daily and this number increases each year Pangnakorn, and in the fruit industry, banana peels make up around g per g of the total revenue. All those peels may be put into much more use.
Since they are rich with starch and this starch is very easy to extract, potatoes are the most commonly used raw materials.
The propane-1,2,3-triol used in the experiment functions as a plasticizer, an additive used to develop or improve the plasticity of a material.
It disconnects the polymer chains from one another; restraining them from becoming rows of chains and acquiring a crystalline structure. The formation of the crystalline structure is undesired because it is a brittle and fragile structure which makes the plastic brittle and fragile as well.
Instead of the crystalline structure, the formation of film not becoming rows of chains of polymers is desired. Starch consists of two different types of polymer chains, called amylose and amylopectinmade up of adjoined glucose molecules.
The hydrochloric acid is used in the hydrolysis of amylopectin, which is needed in order to aid the process of film formation due to the H-bonding amongst the chains of glucose in starch, since amylopectin restricts the film formation.
The sodium hydroxide used in the experiment is simply used in order to neutralize the pH of the medium. The 9 th and 10 th pilot experiment I had conducted had been successful in producing plastic, but had started to decay after only 3 days. As a result of the research done to address this issue, I found out that in order to improve shelf life of post-harvest wild mango fruits, sodium metabisulphite can be used Ibadan, This is why the sodium metabisulphite solution was used in this experiment.
Simalarly sized bananas with no injury or bruises on the skin were purchased from the bazaar in order to ensure the experimental process was fair.
A large variety of pilot experiments were done in order to establish the effects of placing the banana peels in 0.
Based on the results of the 12 pilot experiments, the following 2 experiments were selected and were repeated four times:. These treatments were selected based on the quality of the plastic produced by means of thickness, strength and shelf life. All measurements were made as precisely as possible. For safety precautions, surgical gloves were worn throughout the experiment.
The experiment was conducted at a labaratory in the Koc High School and the following equipment was used:. The thickness of the plastic was determined by using a ruler. The shelf life decay was assesed by visual inspection on a daily basis The darkening of the plastic suggested decay.
In this project, I conducted 12 pilot experiments in order to establish the effects of placing the banana peels in 0. Based on the results of the 12 pilot experiments, 2 experiments were selected and were repeated four times. Several trends were recorded as a result of these pilot experiments. These trends were:. These results supported my hypothesis, meaning that I succeeded and manufactured bio-plastic from banana peels.
The reason why I was able to do so was because fruits rich with starch are preferred in the making of bio-plastic and the banana peel is rich with starch. The chemistry behind this is that starch consists of two types of polymer chains, called amylose and amylopectinmade up of adjoined glucose molecules. The HCl used in the procedure hydrolyzes amylopectin and prevents it from making hydrogen bonds with the amylose polymer chain and forming rows of polymer chains, acquiring a crystalline structure.
In the results section of my project report, the results from 4 of the 12 pilot experiments I conducted are shown.Photo via Shutterstock. As then-sixteen-year-old Turkish student Elif Bilgin discovered, the starches and cellulose contained in their outer layer can also be used to create materials that insulate wires and form medical protheses.
Bilgin developed a chemical process that turns the peels into a non-decaying bioplastic that she hopes will help replace the need for petroleum and combat pollution. With figures such as Marie Curie and Thomas Edison to inspire her work, Elif Bilgin spent two years refining her techniques to transform banana peels into plastic.
Noticing that mango peels had been used elsewhere in the plastics industry, she surmised that banana peels could also be a potential source for feedstock. In Thailand, she noted, tons of peels are discarded daily and could be put to a better use than filling garbage heaps.
Bilgin hopes to one day attend medical school and dreams of creating a greenhouse made entirely of waste. She joined 14 other teens and their innovations, including Ann Makosinski from Canada who invented a flashlight that operates using only the heat from the human hand. It also means that I have started the process of changing the world, which makes me feel like a winner already. Via Phys. Remember Me.
I'll do the best i can dotill then "All the best" for more of your inventions!! Paul Bovis, you either work for big oil or are actually forward thinking, I can't tell. You're right about the flip side, but I think alleviating the oil could have a largest impact. Really depends on the infostructure it's put into, in africa which consumers bananas in mass, and doesn't have much oil Manfacturing I could see it making a large positive impact. In the rainforest region yes Paul could prove correct.
People like this girl are my heroes. This is amazing. You go girl! A prize well deserved and more.
BIOPLASTIC FROM BANANA PEEL RESEARCH PAPER
People like you give me faith renewed that perhaps we can do something to combat what we have begun doing to this Earth I only wish I could contribute the way you have. But I will do my part the best I can. I am impressed! This is the kind of forward thinking we need today instead of those climate change deniers.
Genius starts young and I'm glad this young person is using her genius to take care of our plastic problems. My wife wrote a blog entry on the Great Pacific Garage patch where a lot of that plastic ends up. Here's a link if interested. Keep up the great work Elif!
