DMD Sustainability & Environmental Compliance 2 — Questions and Answers
Question 1: What is 'ISO 14001' and why is it relevant to manufacturers?
- An international standard for Environmental Management Systems that helps manufacturers manage their environmental impacts systematically (Correct answer)
- A standard for hazardous material labeling
- An EPA certification for zero-waste facilities
- A standard for measuring carbon emissions in manufacturing
Correct answer: An international standard for Environmental Management Systems that helps manufacturers manage their environmental impacts systematically
ISO 14001 provides a framework for establishing, implementing, and improving an Environmental Management System (EMS) to control and reduce environmental impacts.
Question 2: What is 'energy intensity' as a sustainability metric in manufacturing?
- The amount of energy consumed per unit of production output (Correct answer)
- The peak electrical demand of a manufacturing facility
- The intensity of light required in manufacturing processes
- Total annual energy consumption of a plant
Correct answer: The amount of energy consumed per unit of production output
Energy intensity (energy per unit output) normalizes energy consumption for production volume, enabling meaningful comparisons and tracking of efficiency improvements.
Question 3: What does 'Restriction of Hazardous Substances' (RoHS) compliance require from US manufacturers selling in the EU?
- Restricting or eliminating specific hazardous substances like lead, mercury, and cadmium from electronic products (Correct answer)
- Restricting the use of overseas hazardous chemicals only
- Reporting hazardous substance inventories to OSHA annually
- Replacing all hazardous materials with US-sourced alternatives
Correct answer: Restricting or eliminating specific hazardous substances like lead, mercury, and cadmium from electronic products
RoHS restricts the use of specific hazardous substances (lead, mercury, cadmium, hexavalent chromium, PBBs, PBDEs) in electrical and electronic equipment sold in the EU.
Question 4: Which concept describes a manufacturing system designed to eliminate waste by keeping materials and products in use as long as possible?
- Circular economy (Correct answer)
- Linear economy
- Closed-loop recycling only
- Extended producer responsibility
Correct answer: Circular economy
A circular economy keeps resources in use as long as possible through designing for reuse, refurbishment, remanufacturing, and recycling at end of life.
Question 5: What is 'water footprint' in the context of manufacturing sustainability?
- The total volume of freshwater consumed and polluted in manufacturing operations and supply chains (Correct answer)
- The size of water treatment facilities at a plant
- The measurement of water leaks in a cooling system
- The cost of water utilities in a manufacturing facility
Correct answer: The total volume of freshwater consumed and polluted in manufacturing operations and supply chains
The water footprint measures all direct and indirect freshwater use and contamination across manufacturing operations and supply chains.
Question 6: What is 'remanufacturing' in sustainable manufacturing practices?
- Rebuilding used products to original performance specifications using a combination of used, repaired, and new parts (Correct answer)
- Manufacturing products a second time after a quality recall
- Reusing raw materials in a different product line
- Re-running a batch of products through a second production pass
Correct answer: Rebuilding used products to original performance specifications using a combination of used, repaired, and new parts
Remanufacturing restores used products to like-new performance, extending product life and significantly reducing energy and material use compared to new manufacturing.
