Recycling contamination rates of 15-25% make municipal curbside programs net-cost operations, but cities cannot politically cancel them

Municipal curbside recycling programs in the US average 15-25% contamination rates (non-recyclable items mixed in), which makes sorted material unsellable or requires expensive secondary sorting. The total national cost of contamination is estimated at $3.5-4 billion annually. So what? Materials Recovery Facilities (MRFs) that process curbside recycling operate at a loss when contamination exceeds 10%, turning recycling from a revenue source into a cost center that competes with other municipal budget priorities like road maintenance and public safety. So what? When China's National Sword policy (2018) and subsequent import bans eliminated the market for low-quality recyclables, cities that had been exporting contaminated bales suddenly had nowhere to send material, and many quietly began landfilling collected recyclables while still charging residents recycling fees. So what? Residents who see their carefully sorted recyclables go to landfill lose trust in the system, further increasing contamination rates in a vicious cycle -- 'if it all goes to the landfill anyway, why bother sorting?' So what? The 76% of recyclable material lost at the household level represents embedded energy, water, and raw materials that must be re-extracted, increasing mining, logging, and petrochemical production with their associated environmental damage. So what? Small and mid-size cities (50,000-200,000 population) are trapped: canceling recycling is politically toxic, but running contaminated programs costs $686+ per ton to collect with minimal material recovery value. The problem persists because single-stream recycling (all materials in one bin) was adopted for convenience but dramatically increased contamination; extended producer responsibility (EPR) laws that would shift costs to manufacturers exist in only a handful of states; and MRF sorting technology has not kept pace with the proliferation of non-recyclable packaging that looks recyclable to consumers.
