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 highlights the role of bioplastics, which are made from natural monomers and can be broken down by microbes, reducing landfill waste. Examples include dissolvable stitches made from polyglycolic acid and packaging materials like carrier bags and egg cartons that are now made from recyclable materials.

What are the consequences of not recycling waste?

• It fills up landfills and destroys habitats.

• It increases biodiversity.

• It creates more jobs.

• It reduces pollution.

What is the role of enzymes in the breakdown of polyglycolic acid?

• They break it down into monomers.

• They transform it into oxygen.

• They make it indestructible.

• They convert it into water.

How are bioplastics beneficial to the environment?

• They are non-biodegradable.

• They are made from petroleum.

• They can be broken down by microbes.

• They are cheaper to produce.

What are bioplastics made from?

• Natural monomers like cellulose and lactic acid

• Glass fibers

• Metal alloys

• Synthetic polymers

What material is now commonly used for egg cartons instead of polystyrene?

• Metal

• Recycled newspaper material

• Glass

• Plastic
