Organic waste makes up about 20% of the waste stream and can be converted into compost and wood mulch rather than being land-filled as trash.

You can dispose of organic materials (listed below) at discounted rates, or even free-of- charge.  The yard waste drop-off is sponsored by the city of Boulder and Boulder County.  It is free to city of Boulder residents, and unincorporated Boulder County residents pay 40% less than standard trash disposal rates.  These programs are administered by Western Disposal. 

The following materials are acceptable at the yard waste drop-off:

- Grass clippings
- Leaves
- Weeds
- Flowers
- Woody waste up to 6” in diameter
- Sawdust
- Food waste, both vegetable and meat

These items are not accepted:

- Sod
- Woody waste over 6” in diameter
- Animal droppings
- Lumber
- Construction debris
- Dirt, rock, brick or pavers
