What is the aim of the biological loops in the butterfly diagram?

Choose the correct answer.

To return natural materials to the environment in a way that enhances the natural environment.

To ensure that all circular materials are biodegradable.

To stop biological monocultures.

To ensure that crops are planted according to nature’s seasons.

How does Stephanie Benedetto summarize the circular activities of Queen of Raw?

Choose the correct answer.

It sells raw materials for hobby dressmakers.

It ensures there is no fabric waste and that any leftovers get reused and go back into the circular flow of materials.

It ensures that all fabric and textile waste is burned and provides energy for the Queen of Raw operations.

It provides a color-matching service for customers with leftover fabrics.

What step is being taken by more and more governments to address the plastic problem?

Choose the correct answer.

They are demanding that an increasing proportion of the plastic in plastic packaging must be recycled plastic.

They are awarding a "less plastic" label to companies that replace or reduce plastic packaging.

They are restricting the production of plastic packaging items to force domestic companies to look for alternative materials.

They are increasing the import duties for products with plastic packaging.

Which of these facts does Stephanie Benedetto from Queen of Raw use to illustrate the problems of textile waste?

There are two correct answers.

Textile production is the number two polluter in the world of clean water globally.

One t-shirt takes an average 700 gallons of water to produce and another 700 gallons of water to wash in a typical lifetime.

The problem of textile waste would be solved if we all made our own textiles.

T-shirts produced with non-organic cotton need twice as much water to produce and wash as organic cotton T-shirts.

What do the two halves or cycles represent in the circular economy butterfly diagram?

Choose the correct answer.

The cascade loops of the value circles in the circular economy.

The materials and energy input, representing the starting point for developing parts.

The continuous flow of technical and biological materials through value circles.

An illustration of the principle that even materials of low value should be reused.

Why does it make economic sense to see waste as value?

There are three correct answers.

Recovering and reusing materials from waste can be easier and cheaper than extracting raw materials from the earth.

Reuse and upcycling of discarded products reduces the use of scarce resources (such as water and energy).

Certain raw materials could be used up by the middle of this century but could continue to be obtained from waste.

In the foreseeable future, all waste will be able to be broken down into its valuable components and the owners of waste can expect big profits.

Reusing discarded products reduces costs because companies save their R&D resources by eliminating the need to develop new products.

What is the recycling loop of the butterfly diagram often referred to as?

Choose the correct answer.

The "loop of last resort"

The "loop of reuse"

The "loop of raw materials"

The "value chain loop"

What are technical loops in the butterfly diagram designed to do?

There are two correct answers.

Process stock management.

Prevent value being lost.

Retain the value of materials and products.

Manage raw materials.
