- If collaboration is a primary goal of the PPSI, more explicit agreements (e.g a collaboration policy) amongst key PPSI participants would be required for the sustained and significant commitments (time, funding) required for effective collaboration. (See Question 1).
- Some retailers declined to show the fee on the receipt. Retailers were expected to want to show the fee to indicate the extra amount was not part of their price.
- There were a large number of unlabeled and/or rusty cans of paint that cannot be accepted by program. The collection sites are instructed to not open the cans of paint and those cans are treated as non-program materials which must be managed by OR. (See Question 5)
- PPSI had limited representation from retailers and so the fact that they play a large role in the Oregon paint collection infrastructure was surprising. Additionally, large retail chains declined to participate.
- The private-public partnership and the waste hierarchy model (reduce, reuse, recycle) were at odds in this program.
- The reliance on retailers as collection locations had a negative impact on the program’s ability to divert high quality leftover paint for reuse, which is ranked as a preferred use.
