Section 3 Scenarios

Milestone, Target Completion Date and Responsible Party*

Activity

Refine and finalize crumb rubber specification and suppliers 5. Monthly and final check- ins; project crumb rubber use

4a. Prepare specification. This may be completed at the time the prototypes are ready for conducting testing. (Denise Kennedy in consultation with manufacturer rep., crumb rubber producer and appropriate manufacturer technical assistance specialist TBD) 5a. Monthly check in calls (short discussions between, Technical Assistance Managers and manufacturer rep for updating and reporting) 5b. Final check in April 2024 (Manufacturer rep. provides projections and summary of status/outcomes to Denise Kennedy)

Assistance Activity Ends

May 2024

Total Budget See Page A3: Cost Sheet for Scenario A - $252,390.00 * Proposed budgets for Scenario A are shown in Attachment A.3 within Appendix A. We propose that budgets for FCS assistance services are not shared with participating manufacturers to keep them focused on milestones and assistance outcomes offered, and to reduce negotiations that could reduce CalRecycle’s flexibility in allocating budget in a way that maximizes benefits across the program. We propose to share assistance task budgets with CalRecycle as part of the overall Summary Report and contract amendment process under Task 2D.

Scenario B

Scenario B RFP Description: Custom Production is a 25-year-old profitable company with sales of $50 million per year. The company produces a variety of thermoplastic elastomer products for it to sell as well as on a contract basis for other companies to sell. The company has written authorization from 3 companies to use an appropriate amount of crumb rubber in a total of 10 products which are currently produced with virgin material. The products may be able to substitute 10% - 25% of the rubber portion with crumb rubber of 50 mesh or finer, depending on the product and performance specifications. Because of the nature of the production process, a higher natural rubber content crumb rubber may be preferred. It is essential that performance of the products using crumb rubber be equal or better than those using virgin materials. Describe how you would: identify the potential crumb rubber usage, appropriate mesh size and original source of the rubber; identify the appropriate technical assistance (product sample production, applicable [ASTM and/or alternative] testing and certifications) and corresponding budget; and prioritize the 10 products. Provide an activity plan and budget for the top 7 products. Describe how you would implement the activity plan and provide an appropriate timeline. What are other important considerations with thermoplastic elastomers? Identify 3 benefits that can be communicated to Custom Production to assist in their decision to use crumb rubber. Again, most of the requested information is covered above under General Approach to Scenarios. There is no information provided on the nature of the products, other than they are currently made with thermoplastic elastomers. Therefore, we assume the products are injection molded and that crumb rubber will first be prepared with polymers and other additives by a compounder either within their company or externally We would involve early in the process our rubber-plastic compounding specialist Richard Warpack of Modern Concepts, Inc. Some considerations for using crumb rubber with thermoplastic elastomers include:

• As with all feedstock conversion, customer needs and required product performance characteristics must drive the process. This is especially true for injection molded
