The City of Stanton Public Works staff recently picked up two loads of OC San’s composted biosolids produced by Synagro. As a benefit to our local cities and member agencies, OC San is encouraging local trials and demonstrations of composted biosolids before buying directly from compost producers like Synagro. Local cities are now required by CalReycle regulations (SB 1383) to buy compost and other products derived from materials diverted landfills.

Composted biosolids are a safe and nutrient-rich soil amendment used to grow beautiful plants and build healthy soils with higher water-retention capacities. The composted biosolids are created from OC San’s biosolids that are treated organic matter recovered through the treatment of wastewater.

The City of Stanton staff used the composted biosolids to amend soil at their Beach and Orangewood Pocket Park pictured here with many bees and butterflies enjoying the lavender and lantana.

The composted biosolids worked so well, the City later ordered a full truck load to finish the pocket park and other projects.
