Our Mission: 

The mission of South Bay Sustainable Communities Network is to build healthy and sustainable communities by encouraging people to create lasting change in their daily lives through education and community engagement in environmental conservation, neighborhood composting, and sustainable urban farming. 

"The Earth will not continue to offer its harvest, except with faithful stewardship. We cannot say we love the land and then take steps to destroy it for use by future generations." 

- John Paul II

Hilltop Hiigh School's Y4SF Team

Updated Y4SF Totals 

With a little over a month into the new school year, all Y4SF schools combined have accomplished diverting 10,700 lbs of food waste from the landfill, of which more than 9,000 lbs were edible foods that were rescued and redistributed to food-insecure families. Way to go Y4SF!

Y4SF Students Taking Action

On September 12th, Y4SF students from Otay Ranch, Bonita and Hilltop High School attended the city council meeting to support the single-use plastics reduction ordinance. Facing Chula Vista Mayor John McCann along with the rest of the city council, Y4SF students prepared speeches to express their care and support for such an important cause. 

What we Accomplished in 2022

We composted 50,000 pounds of food waste from our 16 neighborhood drop off locations which prevented...


1,992 Gallons

of gas that would have been used to transport food waste to the landfill.

33,665 Pounds

of Carbon Dioxide greenhouse gas that would have been emitted from our landfill.

Covid-19 has created a plastic disaster! Single-use plastic bans that have been passed are not being enforced and it is taking a toll on the environment. Supporting restaurants with take-home food options has brought on a surge of single-use plastic utensils, straws, bags, and condiment packages. Though useful when eating in a non-home environment, taking these items just to eat at home becomes unnecessary and wasteful! Let's be conscious of the environment and practice sustainability when placing take-out or delivery orders and not include these single-use plastics in our orders. Join us in our "Opt Out Takeout Plastics Campaign" to help reduce single-use plastics in our landfill and cut restaurant expenses by not having to provide these plastics!
