Waste and recycling

Across our operating companies we are working to find new ways to reduce waste, reuse materials and safely extend the life of equipment. We look to find new vendors to increase recycling rates and identify new products that can be recycled.

Managing and reducing our waste (data from 2021)

All company facilities in California, including Sempra’s headquarters, SoCalGas and SDG&E facilities, divert organic waste from entering landfills, in support of implementing California Senate Bill 1383. By 2030, SDG&E also aims to divert 100% of facilities-related waste from landfills by reducing, reusing, recycling and recovering waste materials. In 2021, SDG&E’s facilities generated 2,640 tons of waste, of which 48% was diverted from landfills.

Oncor continues to integrate environmental considerations into its business planning and decision making, working with customers, business partners and regulatory authorities to reduce environmental impacts. In 2021, approximately 65% of operational waste generated by Oncor, such as oil, poles and other electrical equipment, was recycled or repurposed.

In Mexico, IEnova implemented an initiative in 2019 to reduce non-hazardous waste by replacing the type of coagulant used in a wastewater treatment plant with an organic coagulant. This resulted in a 26% reduction in non-hazardous waste at the facility since the start of the project.

In 2021, our businesses generated an aggregate of approximately 6,260 tons of hazardous waste. Hazardous materials teams manage hazardous material storage, recycling, transportation and/or disposal to help ensure compliance with applicable laws. The amount of hazardous waste we generate fluctuates from year-to-year as we work to complete the clean-up of historic manufactured gas sites and replace other energy infrastructure.
