Life Cycle Assessment (LCA)

  1. 1. Life Cycle Assessment Juanma Hernández-Sánchez <juanmah@gmail.com> November 28, 2011
  2. 2. Life Cycle Assessment Raw material extraction Manufacturing Production Disposal Transportation Recycling Use / Consumption by National Institute of Standards and Technology’s Manufacturing Engineering, via Wikimedia Commons
  3. 3. Environmental Impact It is an alteration of the initial characteristics of the environment caused by a project, work or activity It is the set of consequences for human health, welfare of the ora and fauna and the future availability of natural resources attributable to the input or output streams of a system Fundació Fòrum Ambiental. Guía para la ecoe ciencia. 2000
  4. 4. Environmental Impact Assessment It is an instrument that identi es, describes and assesses the expected e ects that cause the realization of a project on various environmental issues Fundació Fòrum Ambiental. Guía para la ecoe ciencia. 2000
  5. 5. Life Cycle Assessment Input Output Raw materials extraction Raw Emissions materials Production Use Energy Maintenance Waste Recycling Waste management
  6. 6. Life Cycle Assessment Extraction of raw materials + Production + Distribution + Use / Maintenance + Waste management
  7. 7. Life Cycle Assessment Extraction of raw materials + Production + Distribution + Use / Maintenance + Waste management
  8. 8. Life Cycle Assessment Extraction of raw materials + Production + Distribution + Use / Maintenance + Waste management
  9. 9. Life Cycle Assessment It is a technique that tries to identify, measure and characterize di erent potential environmental impacts associated to each one of the stages of the life cycle of a product
  10. 10. Life Cycle AssessmentIt does not consider economic issues, neither social
  11. 11. Life Cycle Assessment The goal is to understand the ows of matter and energy involved in the product, material, manufacturing process, packaging, etc. And nd out what are the environmentally critical points, and prevent or remove them using other materials or systems
  12. 12. Phases of the LCA study a) Phase of goal and scope de nition b) Phase of inventory analysis c) Phase of impact assessmentd) Phase of interpretationISO 14040:2006. Environmental management. Life cycle assessment. Principles and framework. 2006
  13. 13. Phase of goal and scope de nition The basic concepts are de ned, such as: I Product system to study I The functions of the product system I The functional unit I The system limits I Assumptions I Limitations I Data RequirementsISO 14040:2006. Environmental management. Life cycle assessment. Principles and framework. 2006
  14. 14. Phase of the inventory analisys Data collection and quanti cation of needed input/output dataISO 14040:2006. Environmental management. Life cycle assessment. Principles and framework. 2006
  15. 15. Phase of impact assessment Understand and assess the magnitude and importance of potential environmental impactsISO 14040:2006. Environmental management. Life cycle assessment. Principles and framework. 2006
  16. 16. Phase of interpretation The results of inventory and/or impact assessment are summarized and discussed as basis for the conclusions, recommendations and decision making according to the objective and scope de nedISO 14040:2006. Environmental management. Life cycle assessment. Principles and framework. 2006
  17. 17. Phases of the LCA study goal and scope definition inventory interpretation analysis impact assessmentISO 14040:2006. Environmental management. Life cycle assessment. Principles and framework. 2006
