Sustainability

• Life cycle Analysis

  • goal = purpose of product
  • inventory = input & output
  • Impact assessment = environmental problems
  • improvement = alternative strategies
• Qualitative Risk Assesment

  1. Hazard Identification
  2. Risk analysis: Estimate the severity (mid - low - high), likelihood (very likely - unlikely), consequences (negligable - severe)
  3. management: reduce or mitigate
• Linear Economy:

  1. Resource Extraction:

  2. Production: Raw materials are processed and manufactured into goods.

  3. Distribution: Finished goods are distributed to consumers through various channels, similar to the circular economy.

  4. Consumption: Consumers use the products as intended.

  5. End-of-Life Stage: disposed

  6. Waste Management:
• circular Economy:

  1. Resource Extraction: raw materials

  2. Production: manufactured

  3. Distribution: costumers

  4. Consumption: consumers use product

  5. End-of-Life Stage: Instead of being disposed of, products are recovered at the end of their life.

  6. Recovery and Regeneration: Materials and components are reintroduced into the economy, either in the same form or in a different form, thus closing the loop and minimizing waste.
