FREE ME Environmental Impact Questions and Answers
Which of the following materials is commonly researched for its potential to reduce environmental impact?
Biodegradable polymers are being extensively researched due to their ability to break down naturally in the environment, reducing long-term pollution and waste accumulation, especially in applications like packaging.
Which of the following is a key environmental concern in the use of composite materials?
Composite materials often combine different types of materials (e.g., fibers and polymers) that are difficult to separate, making recycling challenging. This contributes to waste and environmental impact at the end of the material’s life cycle.
What is the role of life cycle assessment (LCA) in materials engineering?
Life cycle assessment (LCA) is a tool used to evaluate the total environmental impact of a material, including its raw material extraction, processing, use, and end-of-life disposal or recycling, ensuring a comprehensive understanding of its sustainability.
Which factor most significantly contributes to the environmental impact of metal production?
Metal production, especially for materials like aluminum and steel, requires significant amounts of energy, primarily in the extraction and smelting processes. This energy consumption contributes to environmental impacts such as greenhouse gas emissions.
