Methods to Identify SR Opportunities: T04: Participative team management
Barriers: B3-No Information B3 - Concern that product quality may decline as a result of source reduction. |
S21: Expansion activities included updated bath sizes where the chemical wet out process takes place, updated catch trays to improve capture of liquid resin off from the process. Source Reduction - Expansion activities were based on collaboration between all employees including operations and engineering. |

Barriers: B3-Barriers to P2 B3 - Concern that product quality may decline as a result of source reduction. |
W52: Moved to smaller bath size with a lower volume of resin. This reduces the amount of resin used and limits the loss of resin. Implemented a chilling system to help reclaim resin back into the bath. Barriers to P2: B3 - Concern that product quality may decline as a result of source reduction. - We have been able to reduce the amount of resin used at the source but much more reduction would cause quality degradation of the product being produced. |
