Which of the following is NOT an approach to sustainable product design?

Utilizing non-recyclable plastics is not an approach to sustainable product design because sustainability emphasizes minimizing environmental impact and resource depletion. Using renewable materials, designing for longevity, and designing for recyclability all support the goal of reducing waste, conserving resources, and promoting a circular economy.

Non-recyclable plastics lead to increased waste and pollution, as they cannot be repurposed or reintegrated into the production cycle. This choice contradicts the principles of sustainability, which aim to create products that have a minimal negative impact on the environment over their lifecycle. In contrast, the other approaches focus on responsible sourcing and enhancing the lifespan and end-of-life options for products, making them integral to sustainable design strategies.
