WASTE REDUCTION

Solid waste reduction is a vital part of our journey to carbon neutrality. Our original goals aimed to reduce overall waste by 30% from 2015 levels and divert more than 70% of the solid waste generated at our properties from landfills by 2025. In 2022, our total waste reduction rate reached 37%, exceeding our goal, and we diverted 53% of our waste from the landfill. Macerich relies on an in-depth hazardous waste management program that covers all operations. The program encompasses waste collection, chemical or product spill response procedures, personnel training, hazard communication training and emergency response preparedness. This program is managed and updated annually by our VP, Environmental Affairs. In 2022, Macerich did not generate or transport any hazardous waste.

In partnership with our property teams, our retailers and our waste collection partners, our waste reduction practices include:

• IMPROVED WASTE COLLECTION: We work closely with waste collection partners and tenants to remove at least 70% efficient loads, reducing trips to lessen both environmental impacts and costs. Macerich focuses on education and outreach for tenants to help reduce business and packaging waste, including opportunities for polybag recycling through our partnership with Keter Environmental Services.

• RECYCLING: We utilize diverse recycling streams across our portfolio for cardboard, glass, aluminum, plastic and plastic film, paper, organics, used cooking oil and landscape debris. Additionally, we recycle significant levels of our construction waste.

• WASTE-TO-ENERGY: In some locations, where available, we send our waste to be incinerated to produce steam for energy production. These processes redirect waste away from landfills while also reducing our energy footprint.

• ORGANIC WASTE: Sustainable organic waste disposal is fully active in California, New York and selected other properties where available, and we are exploring other options to expand those programs.

• E-WASTE: Drives at our properties support our communities and Company in keeping electronics out of landfills.

While some processes carry a net cost, others generate modest financial returns — an essential balance. In 2023, we will conduct pilot projects to explore emerging technology, including AI, that will enable us to optimize collection times and processes for further efficiencies.

PEOPLE PERSPECTIVE: WASTE DIVERSION

"When it comes to waste diversion, we are continually optimizing the program regarding equipment, training and collaboration with our partners to increase our efficiency and diversion rate. Education is key, and it’s rewarding working together with property managers to improve waste at our centers. The program is very successful and will continue to be."
