Compost & Organics Rules

The city’s solid-waste and recycling programs set requirements for curbside composting, accepted materials, and container rules. Residents should follow the Public Works Solid Waste & Recycling instructions for food scraps, yard waste, and permitted curbside containers. City Solid Waste & Recycling[2]

  • Curbside organics: follow the approved container and sorting rules on the city page.
  • Collection schedule: setouts must follow the published pickup days.
  • Fees: residential rates and organics service options are listed by Public Works.
Using approved bins prevents contamination and service disruption.

Plastic Bag and Single-Use Plastic Rules

Westminster’s municipal code and city waste programs address single-use plastics and recycling expectations. Check the municipal code for specific ordinance language and definitions relating to prohibited items and retail responsibilities. Westminster Municipal Code[1]

  • Retail requirements: businesses may be subject to rules for single-use bag distribution and required alternatives or fees, as defined in code.
  • Recycling contamination: prohibited items can lead to collection refusal or additional charges.

Pesticides & City Vegetation Management

Parks, open space and right-of-way vegetation management is handled by the city’s Parks & Recreation division; the municipal code provides the legal framework for permitted activities and restrictions. For program details or pesticide-use notices, consult the municipal code and contact Parks or Code Enforcement for specifics. Westminster Municipal Code[1]

  • Integrated Pest Management: city-managed lands use best-practice IPM approaches where described by city programs.
