The Universal Zero Waste Ordinance requires composting at all businesses in the City of Boulder and recognizes the additional cost that compostable bag liners pose. The city is committed to doing its part to support businesses and the public in composting properly. Keeping plastics out of the compost stream is vital to production of a clean, marketable product. Having a quality end product also ensures that compost programs, which greatly reduce methane emissions and our climate impacts, can continue.

Program funding comes from the Disposable Bag Fee, the 10¢ fee on disposable plastic and paper checkout bags at all grocery stores in Boulder. Plastic bags are contaminants in both the compost and recycling waste streams and the Green Bag Giveaway program benefits businesses that are composting and helps keep plastic contamination out of the compost and environment.


To qualify, any Boulder business simply needs to fill out the Zero Waste Reporting Form showing they are composting and recycling according to ordinance requirements. Businesses should be prepared to submit photographic evidence of their waste stations to demonstrate this clearly.

Visit the Universal Zero Waste Ordinance page for compliance details, instructions and resources.


When your Zero Waste Reporting Form is approved, you will receive emailed instructions for beginning your free 12-month subscription through the city's compostable bag vendor.

We appreciate that the City of Boulder is making it even easier to compost. The free compostable bag program is just one example of how the city is doing a great job supporting the restaurant community’s push toward zero waste.
