Aspen, Colorado, implements phase 2 of Organic Waste Diversion ordinance

Aspen, Colorado, has implemented phase 2 of its Organic Waste Diversion ordinance, requiring all businesses and multifamily properties within city limits to separate organic waste from recycling and other disposables.

Building on the ordinance’s initial implementation in 2023, the city says phase 2 is a key step in Aspen’s efforts to reduce landfill waste, cut greenhouse gas emissions and support a more sustainable local waste system.

Phase 1 of the organic waste diversion ordinance required all restaurants to divert their food waste. By the end of 2024, one year into the program, Aspen says it saw 2,000 tons more organic waste diverted from the landfill compared to previous years. Restaurants have been required to compost, donate or dispose of organic waste instead of placing it within regular waste bins. Data for 2025 is currently being calculated. 

The city says it has been working closely with waste haulers, property managers and business owners to prepare for phase 2, offering educational sessions and materials, technical assistance and implementation guidance.

“The success of phase 1 demonstrated the real impact organic waste diversion can have,” says Jimena Baldino, the city’s sustainability programs administrator. “We’re excited to build on that progress, and our goal is to work alongside the community to make this successful. We are focusing on education and support to assist in the roll out of this program.” 

To support compliance, the city is providing free indoor countertop compost containers and educational materials for all multifamily residents and businesses; bear-proof outdoor compost receptacles for multifamily properties; and five centralized bear-proof outdoor compost receptacles in the downtown commercial core for businesses to dispose of their organic waste.
