Miami-Dade deploys CNG trucks to improve recycling efficiency, reliability

The Miami-Dade Department of Solid Waste Management (DSWM) recently deployed new compressed natural gas, or CNG, trucks equipped with artificial intelligence (AI) technology designed to improve the efficiency and reliability of Miami-Dade County’s recycling services.

DSWM launched the first phase of the initiative this spring as part of a new contract with its vendors, and the full fleet is scheduled for deployment by early next year.

“In Miami-Dade, we are leveraging cutting-edge technology to improve our residents' quality of life and make our service delivery more reliable and efficient,” Miami-Dade County Mayor Daniella Levine Cava says. “These new CNG trucks with AI technology not only make our recycling program more cost-effective, they also help us reduce contamination, divert waste and move us closer to becoming a zero-waste county.”

The AI-enhanced trucks are being used to monitor recycling contamination and optimize service operations. The technology incorporated into the new trucks is said to identify contaminants, such as liquids, food-soiled cardboard or hazardous or nonrecyclable materials. DSWM says it will use that information to better educate residents on proper recycling practices, reduce program costs and maintain the quality of recyclables.

“Contamination is one of the biggest challenges in recycling operations,” Miami-Dade DSWM Director Aneisha Daniel says. “It can increase recycling costs, slow down operations and create safety hazards for our staff. These AI-enabled trucks allow us to proactively identify issues and address them immediately, improving both operational efficiency and public service.”

Under the new contract, the trucks feature GPS tracking and video capabilities to provide transparency and accountability for residents while enhancing “operational resilience.” DSWM also says the trucks include features that improve air quality, such as anti-idling technology and CNG fuel.

“CNG is one of the cleanest fuels available for heavy-duty trucks; it reduces noise pollution by approximately 50 percent compared to diesel vehicles and helps lower dependence on foreign oil,” DSWM says.

“As Miami-Dade continues to expand its recycling and waste diversion programs, the deployment of trucks that improve air quality and have AI-assisted monitoring demonstrates DSWM’s dedication to using cutting-edge technology to deliver safe, efficient and environmentally responsible services to the community.”
