Sample interview questions: How do you assess the environmental impact of materials used in your research?
Sample answer:
-
Life Cycle Assessment (LCA): Conduct LCA studies to evaluate the environmental impact of materials throughout their entire life cycle, from raw material extraction and production to use and end-of-life disposal.
-
Material Selection: Choose materials with low environmental impact, considering factors like renewability, recyclability, biodegradability, and toxicity.
-
Energy Consumption: Assess the energy required to produce and process materials. Prioritize materials with low energy consumption or those derived from renewable energy sources.
-
Greenhouse Gas Emissions: Evaluate the greenhouse gas emissions associated with materials’ production, transportation, and use. Aim for materials with a low carbon footprint.
-
Water Footprint: Consider the water usage involved in materials’ production and processing. Select materials that minimize water consumption or are produced using recycled or renewable water sources.
-
Resource Depletion: Evaluate the depletion of non-renewable resources, such as minerals and fossil fuels, used in materials’ production. Favor materials that are sustainably sourced or abundant.
-
Toxicity and Ecotoxicity: Assess the toxicity of materials and their potential impact on human health and the environment. Avoid materials with hazardous or toxic components.
-
End-of-Life Considerations: Evaluate the end-of-life options for material… Read full answer
