ME 59700 Spring 2015 Systems Engineering, Part II Session 22 2 April 2015 Mr. Larry Hopp, CPL
Disposability What does Disposability mean to you? Do you design it in to your systems? Green products Clean processes Eco-factory
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
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
Disposability, Sustainability, & Industrial Ecology Important design dependent parameter Green Product Disassembly Reuse of nonhazardous and renewable materials Requires proactive design approaches Minimize waste
Figure 16.5 Some technology categories for the eco-factory.
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
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
Disposal Phase Replaced System Purge from government inventory Redistributed to fill other needs Hazardous or dangerous items
Disposal Phase Costs Inventory closeout PHS&T Data Management Refurbishment Demilitarization Waste Management
