Answer to Question 1

Answer: Once a suitable substitution for copper was economically viable, the demand for copper declined, making the copper more affordable.

Answer to Question 2

Answer: In many cases we have generated more recyclable waste than the market for these materials can accept; manufacturers may need to develop ways to use recycled materials or produce products that generate less waste.
