BIOPLASTIC FROM AGAR-BASED

Summary

In this video, Nufarahani Binti Abdul Rahman demonstrates the process of creating bioplastic products from agar. The steps involve mixing agar powder, gelatin, and glycerin in water, followed by adding food coloring. The solution is poured into a tray and left to dry, resulting in flexible bioplastics. These pieces are then glued together using a cornstarch solution to form a bag. The finished product is a sustainable, eco-friendly bioplastic bag, suitable for various uses like carrying items such as masks and lip balms, offering an environmentally friendly alternative to traditional plastic bags.

Takeaways

• 😀 The process begins by pouring 800 milliliters of tap water into a pan.
• 😀 Agar powder (20 grams) and gelatin (3 grams) are measured and added to the water.
• 😀 The solution is stirred until it becomes slightly viscous.
• 😀 30 milliliters of glycerin are added gradually to the mixture for flexibility in the bioplastic.
• 😀 Red food coloring is added for coloring, blending well with the solution as it thickens.
• 😀 The bioplastic solution is poured into a plastic tray and left to dry for 2 to 3 days.
• 😀 After drying, the bioplastics become flexible and can be cut into pieces.
• 😀 Cornstarch (5 teaspoons) and water (62 milliliters) are mixed to create a glue for attaching the bioplastic pieces.
• 😀 The bioplastic pieces are glued together to form a bag.
• 😀 The finished bioplastic bag can be used for various purposes, including as a shopping bag or for holding small items like masks or lip balms.
• 😀 The bioplastic is an eco-friendly alternative, reducing pollution compared to traditional plastic bags.

Q & A

What is the main topic of the demonstration?

The demonstration is about producing bioplastic products using an agar base.

What are the key ingredients used in the bioplastic production?

The key ingredients are agar powder, gelatin, glycerin, food coloring, cornstarch, and water.

How much tap water is used in the process?

800 milliliters of tap water are used in the process.

Why is glycerin added to the bioplastic solution?

Glycerin is added to provide flexibility to the bioplastics.

What role does cornstarch play in the bioplastic process?

Cornstarch is used to create a glue that helps attach pieces of the bioplastic together, forming a bag.

How long does it take for the bioplastics to dry?

The bioplastics need to dry for two to three days.

Can the bioplastic product be used for different purposes?

Yes, the bioplastic can be used for various purposes such as packaging masks, lip balms, or even as shopping bags.

What environmental benefit does the bioplastic have?

The bioplastic is environmentally friendly because it is biodegradable and can replace plastic bags that pollute the environment.

How do you ensure that the bioplastics are the right consistency?

The solution is stirred until it becomes slightly viscous and then glycerin and food coloring are added to further thicken it.

What is the purpose of adding food coloring to the bioplastic?

Food coloring is added to give the bioplastic a color, making it visually appealing.
