Life Cycle Assessment: The StagesFor the sake of simplicity the life cycle is divided into unit processes usually broken down as follows: pre-manufacture, manufacture, distribution and installation, use and service, and end of life management. Each unit process is then evaluated in three areas: safety, conservation, and pollution. The inputs and outputs of each life stage are the criteria for evaluation.

What is a Life Cycle Assessment?•Qualitative process used to assess EH&S impacts of product during its lifecycle

What does it provide?•Relative magnitude of EH&S impacts•Areas of information gaps•Priorities for green design•Priorities for green technology development

And….•Raises consciousness of organization

Materials/ Processes of Concern

MATERIALS OF CONCERN FOR GAS TURBINE AND ROCKET PROPULSION SYSTEMS

• Materials Of Concern

• Hazardous Materials Index

• Product Comparisons

• Standard Work

• Green Technology Goals

• Summary

Materials Of ConcernObjectives• Identify hazardous material risks across the enterprise• Provide a deliverable for incorporation into standard work• Create a green index to drive green technology plan

Rationale• Appearance of targeted materials on one or more industry,

customer or regulatory list(s) of hazardous materials• Relevance to Pratt & Whitney product lines or processes• Potential linkage to product and process design callouts

Definition Of Categories• Prohibited

– high risk materials not permitted in new design and development

• Restricted– high risk materials that can only be used with appropriate

levels of approval– plan must be established to validate alternate green material

• To Be Reduced– materials known to have detrimental environmental, health

and safety impacts.

Prohibited Restricted To Be Reduced

Hazardous Materials Index• Purpose

– provide metric to define “greenness” of products– link materials to specifications/design callouts

• Assign “toxicity” values to materials & process specifications based on Purdue University rankings

• Quantify green indices based on Pratt & Whitney Canada algorithm:

Ih = T*nP/N

where: Ih = Hazardous Material Index

T = toxicity value of specificationnP = number of part numbers that call out specificationN = total number of part numbers in engine

Hazardous Materials Index

Implementation

• Establish metrics/set goals

• Establish signoff/approval protocols

• Control via standard work

Green Technology Goals

• Goals established based on driving down product hazardous materials index

• Goal for legacy products will be based on designing out prohibited materials

• Goal for new designs will be based on eliminating the use of restricted materials

Summary

• Comprehensive effort to identify hazardous material risks across the Pratt & Whitney enterprise

• Risks defined by levels of concern

• Standard work tool for designers established

• Goals in process of being defined

• Hazardous Materials Index will drive technology
