Green Chemistry Principles - Design for Degradation

The video discusses the environmental impact of waste accumulation in landfills and introduces the concept of biodegradable materials. It explains how certain polymers, like polyglycolic acid, can dissolve naturally, reducing environmental hazards. The video also introduces bioplastics, which are made from natural monomers and can be broken down by microbes, thus reducing landfill waste. Practical applications of bioplastics, such as in carrier bags and egg cartons, are highlighted as effective ways to minimize waste.

What is one major consequence of waste not being recycled?

• It reduces the need for new materials.

• It fills up landfills and poses health risks.

• It leads to the creation of new habitats.

• It increases the cost of waste management.

How does polyglycolic acid used in stitches break down in the body?

• It is absorbed into the bloodstream.

• It is broken down by enzymes into monomers.

• It evaporates through the skin.

• It remains in the body indefinitely.

What are bioplastics made from?

• Synthetic polymers

• Petroleum-based products

• Natural monomers like cellulose and lactic acid

• Metal alloys

Why are bioplastics important for the environment?

• They are made from non-renewable resources.

• They are more durable than traditional plastics.

• They can be broken down by microbes, reducing landfill waste.

• They are cheaper to produce than traditional plastics.

What material are egg cartons now commonly made from?

• Metal

• Polystyrene

• Recycled newspaper material

• Glass
