Colorado Waste Management Guide 2025

Colorado Waste Management Industry Overview

Colorado generates approximately 6.3 million tons of municipal solid waste annually, serving a population of 5.8 million residents plus millions of tourists. The state operates 46 active landfills (down from 80+ in 1990s), 15 materials recovery facilities (MRFs), and extensive transfer station networks serving mountain communities.

State Waste Laws & Regulations

Colorado takes a largely voluntary approach with limited state mandates and local control:

• Colorado Department of Public Health & Environment (CDPHE): Hazardous Materials and Waste Management Division regulates facilities, tracks diversion, provides grants.
• No Statewide Recycling Mandate: Colorado does not require recycling. Local governments set policies. 15.9% diversion rate (2022) - one of lowest in nation despite urban growth.
• HB19-1163 (2019): Colorado Plastic Pollution Reduction Act. Requires large venues (15,000+ capacity) to provide recycling. Applies to stadiums, arenas, convention centers, major events.
• Local Authority: Municipalities control waste collection and recycling requirements. Denver, Boulder, Fort Collins have mandatory programs for multi-family and commercial.
• 28% Diversion Goal: State goal by 2025. Currently at 15.9%. No penalties for missing targets. Voluntary approach relies on local initiatives.
• Landfill Bans: Many Front Range cities ban yard waste from landfills. Aims to reduce methane and preserve capacity.

Cost Analysis

Colorado waste costs are 10-20% above national averages on the Front Range, with mountain communities 20-40% higher due to transfer station requirements and long haul distances to disposal sites.

Regional Cost Factors

• Denver Metro: $42-$58/month residential. Mix of private haulers. Xcel Energy funds some recycling programs. Growing composting participation. Costs reflect urban density and labor rates.
• Colorado Springs: $35-$48/month. Competitive market with multiple haulers. City partners with private companies. Lower costs than Denver reflect market competition.
• Boulder County: $48-$68/month. Zero waste goals drive comprehensive programs. Eco-Cycle operates large recycling infrastructure. Higher costs reflect progressive policies and high labor rates.
• Fort Collins/Larimer County: $38-$52/month. City provides some services. Strong recycling culture. CSU sustainability programs influence local policies.
• Mountain Resorts (Vail, Aspen, Breckenridge): $45-$75/month residential. Transfer station systems. RFID tracking for pay-as-you-throw. High haul costs to Front Range disposal. Tourism generates additional commercial waste.
• Western Slope (Grand Junction): $32-$45/month. Regional landfills reduce haul distances. Competitive markets, lower costs than Front Range.
