San Antonio Composting Project

San Antonio Composting Project believes that food waste is not garbage -- it's potential. 

We turn food scraps into nutrient-rich soil through the community-powered composting, partnerships with local organizations, and hands-on environmental education. 

By making composting accessible across San Antonio, we're building a greener, more connected city from the ground up. 

What started in 2023 with one bin of red wiggler worms and a mission to fight food waste, has now grown into something that rotates 700 buckets locally. 

We operate at five youth schools, the Alamodome, local cafe's, and a couple of university's even. 

In addition to our bucket exchange program in which we deliver clean, empty 5-gallon buckets and then retrieve those same full of food scraps and organic materials that we bring back to the farm to turn into a nutrient-rich soil amendment/fertilizer through the process of vermicomposting -- or composting with red wiggler worms. 

Please find us online at sacompost.org, and on FB at the page FB.com/sacompost and in the community group: San Antonio Composting Project 501 (c)(3) nonprofit. 

To give you an idea of our impact, at just one of our schools -- Carnahan elementary, we have diverted over 18,000 lbs of food waste from landfill and directly turned it into worm castings through vermicomposting.
