This Fall Green Labs is hosting a competition between all the Lomi Tabletop Composters at Caltech! Currently, there are four Lomi composters on campus: Broad 3rd floor, Chen Basement Level, Chen Level 2, and Chen Level 3. Labs on these floors will compete to turn the most food waste into compost dirt from September - December 2023.

Green Labs will provide a sustainable lunch party for the floor that makes the most compost dirt for our lovely Caltech gardens! Second and third prizes will also be provided.

May the "Lomi-est" lab win! Good luck composters!

If you are interested in getting a Lomi for your kitchen area, please reach out to to learn more!
