I'm still working on Hawaii, Day 2, so today you get to see the souvenir we brought home—for the worms.
It's billed as a compostable cup, and was of excellent quailty for drinking. According the the manufacturer,
Please note that composting is required for biodegradation. These cups will biodegrade within 180 days in a commercial composting facility but can take up to a year or more to biodegrade in a home composting system.
We will see what the worms make of it. I suspect it will take quite a while for them to have an impact on the cup: they prefer their food in small pieces, preferably soft. They will eat the mushier parts first, leaving harder pieces until bugs and microbes have degraded them somewhat—see the piece of corn cob to the right of the cup.
