Hundreds of millions of computers ... obsolete.
*National Safety Council
Each year, 500 million cubic feet of non-recyclable waste is generated from auto recycling activities.
The Problem: Environmental Trends

One Solution: Remanufacturing
The “Ultimate Form of Recycling”
![Page 4: Energy Efficiency and Environmental Protection through Remanufacturing Presented by Miriam Pye Senior Project Manager Industry Research & Development NYSERDA](https://reader035.vdocument.in/reader035/viewer/2022081602/5516614f550346a2698b51ac/html5/thumbnails/4.jpg)
What is Remanufacturing?
An industrial process in which
non-functional or retired products
are restored to
like-new or improved condition.
![Page 5: Energy Efficiency and Environmental Protection through Remanufacturing Presented by Miriam Pye Senior Project Manager Industry Research & Development NYSERDA](https://reader035.vdocument.in/reader035/viewer/2022081602/5516614f550346a2698b51ac/html5/thumbnails/5.jpg)
What is Remanufacturing?
– Primary components come from a used product– Product is dismantled – Condition of parts determined– Components cleaned and restored to original or
“better than new” specifications– Product is reassembled and qualified
![Page 6: Energy Efficiency and Environmental Protection through Remanufacturing Presented by Miriam Pye Senior Project Manager Industry Research & Development NYSERDA](https://reader035.vdocument.in/reader035/viewer/2022081602/5516614f550346a2698b51ac/html5/thumbnails/6.jpg)
Example: Office Chairs
Recycling:• Strip worn fabric and
convert to industrial padding
• Send metal frames to resmelting
• Form resmelted metal into a new product
Remanufacturing:• Replace fabric covers• Repair and repaint
metal frames• Replace worn-out parts,
e.g. fasteners
Remanufacturing vs. Recycling

Life Cycle of a Product
![Page 8: Energy Efficiency and Environmental Protection through Remanufacturing Presented by Miriam Pye Senior Project Manager Industry Research & Development NYSERDA](https://reader035.vdocument.in/reader035/viewer/2022081602/5516614f550346a2698b51ac/html5/thumbnails/8.jpg)

Conserves Energy - avoids energy requirements in raw material acquisition & processing, portion of manufacturing
manufacturing one new automotive starter requires more than 11 times more energy than remanufacturing a starter
Benefits of Remanufacturing
![Page 10: Energy Efficiency and Environmental Protection through Remanufacturing Presented by Miriam Pye Senior Project Manager Industry Research & Development NYSERDA](https://reader035.vdocument.in/reader035/viewer/2022081602/5516614f550346a2698b51ac/html5/thumbnails/10.jpg)
manufacturing one new starter requires more than 9 times more new material than a remanufactured starter
manufacturing one new alternator requires more than 8 times more new material than a remanufactured alternator
Benefits of Remanufacturing
Conserves raw material
![Page 11: Energy Efficiency and Environmental Protection through Remanufacturing Presented by Miriam Pye Senior Project Manager Industry Research & Development NYSERDA](https://reader035.vdocument.in/reader035/viewer/2022081602/5516614f550346a2698b51ac/html5/thumbnails/11.jpg)
– avoids emissions from raw material acquisition & processing, portion of manufacturing
– unlike recycling, metals are not resmelted (a highly air polluting process)
– prolongs product life and keeps products out of landfills and incinerators
Benefits of Remanufacturing
Prevents pollution
![Page 12: Energy Efficiency and Environmental Protection through Remanufacturing Presented by Miriam Pye Senior Project Manager Industry Research & Development NYSERDA](https://reader035.vdocument.in/reader035/viewer/2022081602/5516614f550346a2698b51ac/html5/thumbnails/12.jpg)
Benefits of Remanufacturing
Cost-effectiveness
Unlike recycling, remanufacturing preserves a product’s added value – the labor, machinery and production invested to turn raw materials into a product
A remanufactured product costs on average 50% less than a new product
![Page 13: Energy Efficiency and Environmental Protection through Remanufacturing Presented by Miriam Pye Senior Project Manager Industry Research & Development NYSERDA](https://reader035.vdocument.in/reader035/viewer/2022081602/5516614f550346a2698b51ac/html5/thumbnails/13.jpg)
Benefits of Remanufacturing
Provides jobs
Labor intensive - employs many people
Jobs for low/unskilled workers
Jobs for highly trained engineers

Some Examples of Remanufacturing
![Page 18: Energy Efficiency and Environmental Protection through Remanufacturing Presented by Miriam Pye Senior Project Manager Industry Research & Development NYSERDA](https://reader035.vdocument.in/reader035/viewer/2022081602/5516614f550346a2698b51ac/html5/thumbnails/18.jpg)
How Do They Remanufacture . . .
Kodak’s redesigned “Fling” cameras*
Snap closures for body pieces means cameras are disassembled instead of broken apart.
77 to 86% of parts are recycled or reused - cardboard was replaced by standardized, recyclable plastic.

Single-Use Cameras?
![Page 19: Energy Efficiency and Environmental Protection through Remanufacturing Presented by Miriam Pye Senior Project Manager Industry Research & Development NYSERDA](https://reader035.vdocument.in/reader035/viewer/2022081602/5516614f550346a2698b51ac/html5/thumbnails/19.jpg)
What is the Benefit of Remanufacturing …
~52 million cameras (or 3.9 million pounds of material) were remanufactured in one year - higher than the recycling rate for aluminum cans.
67% less energy is required for manufacturing process of the cameras
Single-Use Cameras?

How Do They Remanufacture . . .
Remanufactured components include: cylinder block, cylinder head, crankshaft, camshaft, & connecting rods.
Wearable parts - bearings, rings, pistons and gaskets - are replaced.
(Many remanufacturers offer better warranties than OEMs.)
Automotive Engines?
![Page 21: Energy Efficiency and Environmental Protection through Remanufacturing Presented by Miriam Pye Senior Project Manager Industry Research & Development NYSERDA](https://reader035.vdocument.in/reader035/viewer/2022081602/5516614f550346a2698b51ac/html5/thumbnails/21.jpg)
What is the Benefit of Remanufacturing . . .
