Laboratory Overview
Students become materials scientists, creating biodegradable plastic alternatives from Caribbean plant materials and testing their environmental impact. This project integrates polymer chemistry, ecology, and sustainable engineering to address plastic pollution in marine environments.
Week-by-Week Implementation
Week 1: Plastic Pollution Research
- • Research plastic pollution in Caribbean waters and beaches
- • Study microplastics and their impact on marine life
- • Investigate current recycling and waste management systems
- • Learn about polymer chemistry and plastic types
- • Interview environmental scientists and marine biologists
Week 2: Natural Polymer Extraction
- • Extract natural polymers from Caribbean plants (banana peels, coconut fiber)
- • Test starch from cassava, plantain, and sweet potato
- • Experiment with natural binders like agar and gelatin
- • Document extraction processes and polymer yields
- • Analyze chemical properties of extracted materials
Week 3: Biodegradable Plastic Creation
- • Create biodegradable plastic formulations using extracted polymers
- • Test different ratios and combinations of materials
- • Add natural additives for strength and flexibility
- • Mold plastics into useful shapes (bags, containers, utensils)
- • Document recipes and manufacturing processes
Week 4: Testing and Environmental Impact
- • Test material strength, flexibility, and water resistance
- • Monitor decomposition in different environments (soil, water, compost)
- • Compare biodegradation rates with conventional plastics
- • Analyze environmental impact and lifecycle assessment
- • Present findings to environmental organizations
