Tim Hoffman previews updates to Waste No More ordinance for construction and events

The Denver Business, Arts, Workforce, Climate & Aviation Services Committee convened on March 19, 2025, to discuss significant updates to the Waste No More ordinance, originally passed in 2022 with overwhelming public support. The meeting, led by Tim Hoffman from the mayor's office and Jonathan Wachtell from the Office of Climate Action, Sustainability, and Resiliency, focused on proposed changes aimed at enhancing waste diversion efforts in the city.

The Waste No More ordinance aims to increase recycling and composting rates across various sectors, including construction, special events, multi-family residences, and non-residential buildings. The committee is preparing to present a revised ordinance on May 7, 2025, which will include specific implementation timelines and enforcement mechanisms.

A key aspect of the proposed updates is the requirement for construction and demolition projects to divert at least 50% of recyclable debris, such as concrete, asphalt, untreated wood, metal, and cardboard, starting in April 2026. This initiative is designed to address the growing concerns about construction waste and its environmental impact. Exemptions will be made for smaller projects and those involving hazardous materials, ensuring that the regulations are practical and manageable for contractors.

The committee also discussed the challenges of implementing waste diversion at special events, where contamination of organic waste is a significant concern. Proposed regulations would apply to events on public property with over 350 attendees, with exemptions for smaller gatherings. The goal is to create waste diversion plans that are feasible and effective, while also providing educational resources to event organizers.

In addressing multi-family residential properties, the committee highlighted the need for improved access to recycling and organic waste services. The Colorado Extended Producer Responsibility Program, set to launch in conjunction with the ordinance updates, is expected to alleviate some financial burdens associated with recycling for property managers.

The discussion also touched on non-residential buildings, which encompass a wide range of property types. The committee aims to streamline waste diversion requirements for these buildings, focusing on those that generate significant waste while allowing exemptions for properties with minimal waste generation.

Finally, the committee acknowledged the complexities surrounding food waste producers, particularly in the restaurant industry. Balancing environmental goals with economic realities remains a priority as the city seeks to enhance organic waste diversion.

Overall, the meeting underscored Denver's commitment to sustainability and waste reduction, with the proposed updates to the Waste No More ordinance reflecting a comprehensive approach to managing waste across various sectors. The anticipated next steps include finalizing the ordinance and continuing to engage with stakeholders to ensure successful implementation.
