What are Datschefski's five principles of sustainable design?

Datschefski's five principles of sustainable design emphasize a holistic approach toward sustainability in product design. The principles—cyclic, solar, safe, efficient, and social—are aimed at reducing environmental impact while promoting a positive social outcome.

The first principle, cyclic, encourages designers to design products with a life cycle in mind, ensuring that materials can be reused and recycled. The solar principle advocates for the use of renewable energy sources in the production process, reducing dependence on fossil fuels. The safe principle focuses on designing products that do not pose harm to human health or the environment. The efficient principle emphasizes the importance of minimizing resource use in the production and operation of a product. Lastly, the social principle highlights the need for designs that contribute positively to society and consider the broader social implications of products.

These principles collectively represent a comprehensive framework that guides designers towards sustainability, making option A the correct answer.
