Zero Waste Events

Headed for Zero Waste

Here in the City of San Mateo, we are dedicated to sustainability and the well-being of our environment and residents. All events sponsored by the City are geared towards achieving zero waste. This means that we strive to divert as much material as we can away from the landfill.

Below are some upcoming Zero Waste events hosted by the City of San Mateo:
