BioPlastic Sequins (BLT)
Inspiration
After working in the fashion industry, I fully understand how an artform can prove to be a major pollutant. The fashion industry is one of the most polluting industries globally and continues to fuel a cycle that accumulates over time. We learned in class that anything can have negative effects on the environment once it accumulates. Accumulation vs Moderation is an age-old question, with the latter being overlooked far too often in the fashion industry. Fast Fashion continues to be a large contributing factor to water, air, and solid waste pollutant but this problem is something that I cannot tackle alone. My goal for this final project is to try and start changes from the most minute details. “Fashion” is a large umbrella term that encompasses everything from the textile to the thread that it is sewn together with. For my final project, I wanted to focus on embellishments, specifically sequins, as a material to find sustainable substitutes via bioplastics. I wanted to create a bioplastic that can be a potential substitute for the millions of plastic sequins that end up as debris once garments or accessories are discarded. Ideally, I want to lessen the accumulation problem by finding methods in which small things that are often overlooked and gradually pose issues/ threats overtime a more viable solution/substitute.

Education for Environmental Issues
Making bioplastic sequins was greatly inspired by my time in China. The new-age consumer market in China is booming with fast fashion and Taobao purchases. With cheap garments so widely accessible, I can only imagine the sequins that are made for dresses, shoes, shirts – you name it, it’s there. Accumulation plays a huge factor in this issue as China is one of the largest waste producers in the world and we often associate plastics with food packaging, plastic bags, and beauty products – but the fashion industry uses it just as much from buttons to sequins (embellishments). I wanted to create the bioplastic sequins as a sustainable substitute but also as a method of educating others about the opportunities to make the world more sustainable in the smallest possible ways. Ideally, this process can be used and implemented in workshops as it can be easily made with accessible household products. I can also see it being mass-produced if a waterproof version can be made. I’m hoping that that the project encourages others to experiment and find discoveries that I was unable to uncover!
Process
Recipe:
Materials/Ingredients:
- Bowl/Measuring Tools (Gram Scale, Beakers, etc.)
- Hot Plate
- Rose Buds/Petals, Lavander
- Gelatin (150 grams)
- Acrylic Board
- Glycerol (50 grams)
- Water (750 ml)
Step-by-Step Process “Cooking”:
- Measure out wet and dry ingredients and separate via bowls & beakers
- Split the water into 2 equal parts (1 is to be boiled, the other is to be kept in room temperature)
- Create the rose/flower water (dye/fragrance) by boiling water and petals until the desired color is reached
- Strain the liquid and remove all excess petals
- Mix the hot rose water with the room temperature water and add gelatin *before gelatin is added*
- Mix in the gelatin until a thick consistency is reached *try to reach a consistency that has NO clumps/chunks*
- Heat the pot with the mixture until a white foam/bubbles in the mixture begin to form and accumulate (DO NOT BOIL)
- Strain the mixture again or use a spoon to remove the white foam/bubbles
- Pour the mixture onto the flat acrylic sheet *Make sure there are no spots or hols, and try to remove air bubbles if possible (Make sure to lay a protective layer underneath the acrylic – the process is messy and very HOT)
Creation
Digital:
After unmolding the bioplastic sheets, the next phase of the project was to finally create the individual sequins. From the initial recipe, it was identified that the bioplastic can withstand the heat of the laser cutter.
*Huge thank you to Andy, our amazing Fab Lab Manager for helping us create NYU Shanghai’s first bioplastic setting on the laser cutter. The project could not be done without your help <3*
To form the single pieces of bioplastic sequins, I created vector images on Illustrator with various traditional and non-traditional sequin shapes. I utilized a variety of shapes, some of which were circular/oblong with soft curves and sloping lines, while others were rigid and more geometric. This gave me a better idea of which sequins held their shapes best. The large more geometric sequins felt a bit more stable or rigid (duh lol), BUT if the goal for the use of the sequin is to look more flowy or mobile, the flat more circular sequins would be STUNNING.

Lasercutting:
This process is probably the most terrifying (lol). The drying time for the bioplastic sheet greatly differs on the width (3-5 days) for a thin o.5cm sheet and even greater for something larger. Due to time constraints, we were able to create (2) full sheets and we wanted to keep one for display – in short, we had (1) sheet to work with. The process of laser cutting also took a tremendous amount of time as we had to make sure the settings in the laser cutter was PERFECT. (No room for error!)
Perfect Settings:
Speed – 100%
Power – 27%
Frequency – 30%
Things to note:
There was ALOT of smoke. Sis, turn the fans ON. Watch out for air bubbles, they were a bit tougher to cut so try and get as much air bubbles out as possible during the pour/drying phase. We also used flowers to organically try and color the dye (it barely worked) but some petals were left in the mixture even after running it through a sieve. The flowers or organic material left in the bioplastic has the risk of burning in the laser cutter, so exercise caution.

Limitations
Veganism (Animals are Friends): After trying several experiments with all-natural plant-based ingredients to make the bioplastic, they unfortunately failed. The gelatin was the most viable and produced the strongest most plastic-like material.
Chitosan (Seaweed): The final product was STUNNING in terms of texture. The dried product was as hard as plastic or a literal rock. No, but really, it was so tough it was fantastic. The biggest problem was the way in which it dried. In order to create the sequins I wanted, I first had to create a FLAT textile that I could later cut. The chitosan curls up after drying even after being left with a weighted object and sandwiched between two acrylic boards. If I found a way to keep it flat, I would’ve used this technique. It’s also important to note that the chitosan recipe required a tremendous amount of dried Chitosan(seaweed powder) to create. For the future, I’d love to try what Marcela suggested – to embrace the curling and create a textile or item that highlights or fully utilizes this curl aspect <3.
Agar-Agar: I’m gonna keep this nice and short. It molds. I tried adding vinegar to prevent the molding and it changed the chemical composition and smelled insane. The final product was also way too thin and less resilient than both chitosan or gelatin.
Waterproofing: The biggest counter-argument and issue I had with this bioplastic recipe/proof of concept is that unlike regular plastic or metal sequins the lifespan is not long. The bioplastic is not waterproof and will disintegrate when exposed to large quantities of water. Technically, I could’ve coated it with a waterproof coating but it would defeat the purpose of being biodegradable. I also wanted to keep it as organic as I could, even if it was animal-based :(. Oddly enough, I took a piece of the bioplastic with me in the shower (don’t judge lol) to test the waterproofing ability.
Here’s what I learned: The bioplastic takes about 15-30min to show signs of wear in a humid/steam/”wet” environment. When exposed to a direct flow of water, it will be destroyed within 5-10minutes. My partner(my boy Kenneth) made the recipe in larger molds that produced thicker bioplastics that were stronger and more waterproof. His bioplastic recipe/molding process created a byproduct that is most likely (2x) as strong.

Future Implementation
Here’s what I want to see:
- BioPlastic as a substitute to small plastic “things” we often don’t think twice about
- A waterproof bioplastic that is strong and resilient
- People to think twice about their purchases and the details within their decisions
- Support of smaller brands like the Sustainable Sequin Company
- For large brands to be trendsetters and invest in innovative solutions to an ongoing problem they have caused\
