Yard waste drop-off and free mulch in Colorado
In much of the West, yard waste drop-off is called green waste or yard debris drop-off. We list 5 sites in Colorado (all from official sources); 2 take brush and branches, 2 give away free mulch or wood chips, and 1 offers free compost. 1 of the 5 list a residency or eligibility rule on the source page, so bring ID or a utility bill. 1 is seasonal or event-only. Coverage for Colorado is still thin — many towns and counties run programs we haven't listed yet, so check your city or county public works page too.
By type: 4 yard waste drop-off, 2 compost pickup, 4 mulch / wood chip pickup, 2 brush & branches.
Call ahead. Hours, fees, residency rules and accepted materials change. Call or check the official source page before you go. Every listing links to its source.
