Cambridge City Hall

Everyone Welcome!

It’s a science takeover at Cambridge City Hall!

Dig a little deeper into the science and technology that keep 911 dispatchers hopping, clean water running, traffic lights blinking, and compost and recycling out of landfills. Enter a raffle to record your own voice for the Accessible Pedestrian Signal at a crosswalk, and join in on the open data scavenger hunt!

Stations will be set up throughout the halls, and interesting talks are taking place in City Council’s Sullivan Chambers, on topics ranging from urban rain gardens to going solar to public safety.

Composting in Cambridge
Department of Public Works Recycling Division
Michael Orr, Recycling Director
In 2014, Cambridge launched curbside composting for the Monday trash and recycling collection route. During the pilot program, we collected over 800 tons of food scraps! We are excited to bring curbside composting citywide in April as we work together to reach our goal of reducing trash 30% by 2020.
Recycling Director, Michael Orr, will talk about how curbside composting developed in Cambridge, how the program works, and how our food scraps are no longer emitting greenhouse gases in landfills but instead creating clean energy and fertilizer!


2:30 – 3:00 PM
Get Rid of it Right!
Department of Public Works Recycling Division
Michael Orr, Recycling Director
The new “Get Rid of It Right” Tool, featured on the Department of Public Works’  Recycling Division website at, is a quick and easy way to determine how to get rid of unwanted items in your home.
