VOICED: Cereplast, a greener alternative to plastic

The video discusses the environmental issue of plastic waste in landfills and introduces biodegradable alternatives developed by companies like Cereplast. These alternatives use materials such as corn and tapioca, which decompose without leaving chemical residues. The video also highlights the benefits of hybrid products that combine traditional plastic with cornstarch, reducing environmental impact. However, challenges such as higher costs and potential impacts on food supply are noted. To address these, Cereplast is exploring nonfood materials like algae, which can be grown cheaply and provide biomass for new products.

What is the primary material used by Cereplast to create biodegradable products?

• Glass

• Plastic

• Corn and tapioca resin

• Metal

How do Cereplast's hybrid products differ from traditional plastics?

• They are made from recycled glass.

• They are made entirely from metal.

• They are 50% traditional plastic and 50% cornstarch.

• They are more expensive than traditional plastics.

What is a significant challenge associated with biodegradable plastics?

• They are about 20% more expensive.

• They decompose too quickly.

• They are not environmentally friendly.

• They are cheaper than traditional plastics.

Why is algae considered a promising material for biodegradable plastics?

• It is difficult to cultivate.

• It can be grown artificially at low cost.

• It is a non-renewable resource.

• It is a traditional food source.

What is the potential impact of increased production of biodegradable plastics on food supply?

• It will decrease food prices.

• It may increase the price of food-related materials.

• It will make food more abundant.

• It will have no impact on food supply.
