Floor Pan Plug from Paint
Sludge "From Paint to Part" |
| Application Description: Resin contains 25-27% paint
sludge that was formerly landfilled. 600,000 lbs/yr that were being landfilled are being
diverted to pan plugs. |
Single Most Unique Feature: The Haden Type II sludge
drying process produces a product of quality, properties and characteristics that can now
be reused in vehicle components. |
| Process Descriptions:The material is extruded, die
cut, and then heat staked to a stamping. The combination of composition, curing system,
and particle size makes this possible. |
First Usage of Process?: Yes. Previous attempts to
re-use sludge processed differently resulted in a product that abraded molding/extrusion
equipment, a non-uniform particle size distribution, particles too large to incorporate
and clogged filters. |
| Formerly Used Process: Attempts were made to grind
the sludge produced by other processes, but the cost was $0.10 -$0.15/lb--cost
prohibitive. |
Tooling Innovations: Haden type II dryer |
| Material Innovations: Composition and curing system. |
Mass Savings: 13% |
| Cost Savings: Cost of landfill avoidance +$450,000
total. Suppliers have offered $240,000 to buy this material, F.O.B. our facility. |
Cost Avoidance: Landfill avoidance $160,000. |
| Direct Consumer Benefit: NA |
Is Technology Transferable?: We are in the process of
introducing the Haden Type II dryer process to additional assembly plants and the parts to
additional vehicles. This year 20 million parts. |
| Significant Safety Benefit: NA |
Significant Environmental Benefit: Landfill avoidance
of 600,000 lb/yr now rising to 5 million pounds as other assembly plants are converted. |

door to get this stuff." Quote from materials engineering supervisor at
DaimlerChrysler. |
