Green Chemistry Principles - Renewable Feedstocks

The video discusses the non-renewable nature of crude oil and its environmental impact, particularly in the production of printer inks. It introduces renewable feedstock as a sustainable alternative and highlights the development of soy-based inks, which are more environmentally friendly and easier to recycle compared to petroleum-based inks.

What is a key characteristic of crude oil that makes it non-renewable?

• It can be produced by humans.

• It is derived from plants.

• It takes millions of years to form.

• It is an infinite resource.

Why is renewable feedstock considered more environmentally friendly?

• It is cheaper to produce.

• It is easier to transport.

• It reduces harmful waste from crude oil processes.

• It is more colorful.

What is a major advantage of soy-based inks over petroleum-based inks?

• They are brighter and more environmentally friendly.

• They are more expensive.

• They are less bright.

• They are derived from non-renewable resources.

How are soy-based inks beneficial in the recycling process?

• They require special chemicals for removal.

• They do not need to be removed.

• They can be removed with ease.

• They are harder to remove from paper.

What challenge is associated with recycling paper printed with petroleum-based inks?

• The paper cannot be recycled.

• The ink is too bright.

• The ink removal process is difficult.

• The ink is easy to remove.
