Answer: Refurbishing old electronics. Extends electronic lifespan rather than immediate replacement.

Flashcard 29: Which material is commonly downcycled?

Answer: Plastic. Recycling into lower-quality products due to material degradation.

Flashcard 30: What is the definition of waste reduction?

Answer: Minimizing waste generation at the source. Prevents waste from being created rather than managing it after production.

Flashcard 31: Which waste reduction method involves reusing materials?

Answer: Recycling. Recycling processes used materials into new products instead of disposal.

Flashcard 32: What is the primary goal of waste reduction?

Answer: To reduce the volume and toxicity of waste. Addresses both quantity and harmful properties of waste streams.

Flashcard 33: Identify a benefit of reducing industrial waste.

Answer: Lower production costs. Less material input reduces manufacturing expenses and resource costs.

Flashcard 34: Which type of waste is most beneficial to compost?

Answer: Organic waste. High carbon content decomposes efficiently into valuable compost.

Flashcard 35: What is e-waste?

Answer: Discarded electronic devices and components. Contains toxic materials requiring specialized disposal methods.

Flashcard 36: Name a policy tool for encouraging waste reduction.
