Which type of waste should a homeowner recycle in their backyard as part of a composting project?

California State Senate Bill 1383 (SB 1383), requires the reduction of organic waste disposed of in landfills. Organic waste is food scraps and food-soiled paper from kitchens and food operations and yard waste such as garden and landscape waste, organic textiles and carpets and wood waste.

Reason for Changes

According to the Environmental Protection Agency, organic waste accounts for a significant portion of California’s waste stream. Left to decompose in landfills, the organic waste releases methane, a gas that traps the sun’s heat, warms the atmosphere and contributes to climate change. Organic waste in landfills also emits air pollutants such as fine particulate matter (PM 2.5), which contributes to health conditions like asthma. To address this issue, Senate Bill 1383 was signed into law and targets the reduction of pollutants, including methane. Cities throughout California must meet the new reduction limits through organic waste reduction and recycling.

Collection and Recycling

Implementing Senate Bill 1383 requires extensive procedural changes and significant coordination. The City of San Diego is developing collection operations, amending agreements with non-exclusive franchise haulers, amending the City’s municipal code, enacting building requirements, preparing enforcement responsibilities and strategizing public education and outreach efforts. Participation in this exciting new organic waste recycling program is vital to San Diego's future.

Food and yard waste collected will be recycled using:

• Composting facilities that make soil amendments, materials that are added to soil to change and improve it.
• Anaerobic digestion facilities, technology and microorganisms break down organic waste in closed spaces where there is no oxygen and create renewable natural gas.

Homes Serviced by the City

Recycling and waste collection changes are coming to City of San Diego serviced residences. The City will notify residents when organic waste recycling collection services will begin. Please follow these protocols until otherwise notified:

• Residences with bi-weekly yard waste collection that currently have a green automated, City-provided curbside bin, please continue to discard yard waste only in the bin until otherwise notified and organic waste recycling begins. 
• Residences with yard waste collection that do not have a green automated curbside bin but use manual bins that they provide themselves, please continue to discard yard waste only until a green bin is delivered and you are notified of a date to begin organic waste recycling.
• Residences with no curbside green bin yard waste collection will be notified when they will receive a green bin and a date to begin organic waste recycling.

In addition to curbside organic waste recycling collection, all residences currently have the option to turn their kitchen scraps and yard waste trimmings into compost by having their own-at-home backyard composting or worm composting bin.
