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. 

What we Accomplished In 2023 !

16 community neighborhoods composted 40,000 pounds of food waste, creating 2,000 pounds of compost for the community!

SBSC rescued 7,500 pounds of edible food which was distributed into the community. 

Our Youth 4 a Sustainable Future (Y4SF), a student-led program consisting of 15 High, Middle, and elementary schools throughout the South Bay diverted 68,050 pounds of food waste from the landfill in 2023!

In total, SBSC diverted 115,550 pounds of food waste, which prevented 78,112 pounds of Carbon Dioxide greenhouse gas emissions!

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!

"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."
