Green chemistry, also known as sustainable chemistry, focuses on designing products and processes that minimise or eliminate the use of harmful chemicals.
Why Green Chemistry Matters
Traditional chemical processes often generate toxic waste, consume excessive energy, and harm the environment. Green chemistry offers
solutions by:
✅ Reducing pollution – Minimising
hazardous byproducts.
✅ Saving energy – Using
efficient, low-energy reactions.
✅ Promoting renewable resources – Replacing petroleum-based materials with plant-based alternatives.
Now, let’s explore some engaging research topics in green
chemistry!
Top Green Chemistry Research Topics for Beginners
1. Biodegradable Plastics from Natural Sources
Problem: Plastic pollution is a global crisis.
Solution: Research how to make plastics from cornstarch,
algae, or cellulose** that decompose naturally.
🔬 Experiment Idea:
Compare the decomposition rates of regular plastic vs. biodegradable
plastic.
2. Solar-Powered Chemical Reactions
Problem: Many chemical reactions require fossil fuels.
Solution: Use sunlight
(photocatalysis) to drive reactions, reducing energy consumption.
🔬 Experiment Idea: Test
how different light sources affect reaction speeds.
3. Water Purification Using Plants
Problem: Industrial wastewater contains toxic metals.
Solution: Study how plants like water hyacinth absorb heavy
metals.
🔬 Experiment Idea: Grow
plants in contaminated water and measure metal absorption.
4. Eco-Friendly Cleaning Products
Problem: Many cleaners contain harmful chemicals.
Solution: Develop non-toxic cleaners using vinegar, baking
soda, or citrus extracts.
🔬 Experiment Idea:
Compare the cleaning power of chemical vs. natural cleaners.
5. Converting CO₂ into Useful Products
Problem: Excess CO₂ causes climate change.
Solution: Research methods to convert CO₂ into fuels or
plastics.
🔬 Experiment Idea:
Simulate CO₂ capture and test conversion techniques.
