1. ME 59700 Spring 2015 Systems Engineering, Part II
Session 22
2 April 2015
Mr. Larry Hopp, CPL

2. Disposability What does Disposability mean to you?
Do you design it in to your systems?
Green products
Clean processes
Eco-factory

3. Design for Disposability
Eliminate environmentally unfriendly materials where possible
If you can’t eliminate, then reduce
Design so components can be reused
Designed so components can be readily recycled

4. Design for Disposal
Designing for it prior to production can create a value stream for the firm
Consumption of energy to “demanufacture” or create energy during this phase
Hydrogen or methane released from decomposition can be used to create heat energy to aid in disposal “tear down”
Recovered chemicals from waste water can be used to benefit operations instead of being just something hazardous to be disposed of
Plan for recycling & create a new value stream

5. Disposability, Sustainability, & Industrial Ecology
Important design dependent parameter
Green Product
Disassembly
Reuse of nonhazardous and renewable materials
Requires proactive design approaches
Minimize waste

6. Figure 16.5 Some technology categories for the eco-factory.

7. Manufacturing with Recycling Applications
Recycling of materials is a design objectives
Recycle
Raw materials
Reusable components
Reducing disposal cost
Increase total product value
Could be a major source of cost savings and competitive advantage

8. Manufacturing with Recycling Applications
During production
Waste materials might be reused
Reduce need for more raw materials and reduce cost
Demanufacturing
Reduce cost
Save on high manufacturing cost

9. Disposal Phase Replaced System Purge from government inventory
Redistributed to fill other needs
Hazardous or dangerous items

10. Disposal Phase Costs Inventory closeout PHS&T Data Management
Refurbishment
Demilitarization
Waste Management
