Ricinoleic-Crosslinked Polysulfide (RCP) Sorbents via Inverse Vulcanization
Rejected
This concept did not clear the framework. The reasoning is published in full below.
What the assessment found
| Gross margin at parity | 62.0% |
| Startup CapEx | $182,000 |
| Payback from first sale | 1.7 months |
| Capital productivity | 15.67x |
Why it failed
- Margin fails the operating-cost check
Also flagged
- Price parity asserted, not sourced
- runsheet_no_quantities
A rejection is not a claim that the science is wrong. It means the venture case did not survive: the comparator was not what the buyer actually buys, the comparison was not like-for-like, the advantage fell short of a step change, or the capital and time to first revenue were prohibitive.
