In 2015, a California design student launched a plantable coffee cup after raising $21,077 on Kickstarter. 11 years later, the idea still hasn’t reached shelves, but compostable coatings may finally solve its biggest problem

Plantable compostable coffee cup : In 2015, a California design student came up with an unusual way to rethink disposable coffee cups: make the cup itself something that could eventually grow into a plant.

The concept used biodegradable board with native seeds embedded in the material. After the coffee was finished, the cup could be pushed into soil, kept damp and left to break down as the seeds grew.
