Deterring Bears in Urban Areas

Bears have always been a part of life in the city of Boulder. The city’s urban wildlife conservation project aims to ensure bears and humans can safely co-exist. Through education, awareness and laws, the city is working to limit the food available to bears so they are not drawn to urban areas.

The city’s 2017 Bear Protection Ordinance 8161 aims to protect bears by eliminating access to food rewards found in trash and compost bins.

Bear-resistant carts for trash and compost are required in the area West of Broadway and south of Sumac Avenue. To view a map click here.

Managing Extra and Bulky Material

TRASH: Charged by the 32-gallon unit. Purchase stickers in advance or have charges added to your bill.

RECYCLABLES: No charge for extra recycling. Place in bins, boxes or paper bags beside your recycling cart. Do not use plastic bags!

COMPOSTABLES: Fees may apply depending on your service area.

BULKY ITEMS: Curbside collection available for an additional charge.

For more information, call customer service at 303-444-2037.

Pay-As-You-Throw Ordinance Areas

Pay-as-you-throw (PAYT) is a unit-based pricing policy set by a city or county wherein trash disposal pricing is based on volume — the more you throw away, the more you pay. Collection of recycling, and sometimes compost (where available), is typically included in the trash rate. With PAYT, when you recycle, compost and generate less waste, you’re rewarded with a lower trash bill.

The City of Boulder and Boulder County have implemented PAYT policies and are working to become zero waste communities by reducing the waste created then reusing, recycling composting most of what is discarded. Our area has facilities to manage a wide range of items generated by the typical household. To learn what goes where, use our Waste Wizard tool.

Hosting an event? Make it zero waste!

Western Disposal makes it easy to host a zero waste event with just a few simple steps:

  1. Determine your needs: Give us a call at 303-444-2037, and we’ll customize a plan based on the type of event, length of the event and the number of people being served.
  2. Purchase and pick up your supplies: Zero waste stations consist of a set of three cardboard bins and corresponding color-coded bags for trash, recycle and compost.
  3. Container delivery: Western will deliver your dumpster (or roll-off for a larger event) to your premises.
  4. Post-event: Place the color-coded bags and flattened cardboard bins in the dumpster or roll-off.
  5. Removal: Give us a call, and we’ll remove the container on the next business day.

The bags come back to Western, where we separate them into the appropriate stream for processing. We also provide you with a report on the amount of material you generated and the amount diverted from the landfill.
