We put the manufacturer's claims for SECAO, a yarn spun from discarded cacao shells, against the published evidence. Which ones hold up, and which are still its word alone?
Only 20% of a cacao fruit ever becomes chocolate. The other 80%, the shell, gets burned or left to rot. Burning releases carbon. Rotting attracts the fungus behind black pod disease, the thing farmers spend half their season trying to keep out. Ten tonnes of wet husk for every tonne of dried bean. No market for any of it.
