Designing Plastic for the Future: How To Make a BioPlastic Bag

Bioplastic Creation for Sustainable Materials
📌 The project focuses on creating biodegradable plastic bags using green chemistry in response to New York's 2020 plastic bag ban, aiming for materials that can eventually sprout light.
🌱 The essential ingredients for the bioplastic include gelatin (2 ounces) and a solution made from 4 milliliters of glycerol mixed with 1,000 milliliters of water.
🔥 The solution must be heated to just below boiling (target temperature around 194°F or 90°C), where the gelatin denatures and dissolves.
🎨 Color customization is possible using natural dyes like beet juice, henna, saffron, or spirulina (a biomass of cyanobacteria).

Bioplastic Sheet Preparation and Drying
🧪 After mixing and heating, the warm mixture is poured onto a baking tray, distributed using a chopstick, and any surface bubbles are popped.
🪴 Gardening seeds or chia seeds are embedded into the plastic while warm to incentivize recycling and showcase the material's natural properties.
⏳ The sheets require three to four days to dry completely in an area with proper air circulation to allow all water to evaporate.

Assembling the Biodegradable Bag
✂️ To form a bag, three identical plastic sheets are required; two sheets are cut to the same size for the main body of the bag.
👐 Handles are created by drawing the desired shape on one sheet and tracing it onto the back of the second sheet, ensuring two identical halves.
🔗 The two main sheets are joined by applying a thin line of glue along three sides, pressing them together to form the bag structure.
➕ A final touch involves cutting out a logo (e.g., "thanks") from the third bioplastic sheet and gluing it onto the bag.

Key Points & Insights
➡️ A healthy future requires the pioneering use of sustainable materials by artists and designers.
➡️ The material produced is described as flexible, durable, and light, behaving similarly to traditional plastic bags.
➡️ Embedding seeds is a design strategy used to celebrate and showcase the nature of the biodegradable material.
➡️ The entire process emphasizes using readily available pantry or grocery store items for creation and coloring.
