Deposit system fully launched in Poland January 2026. Municipalities lose sales revenue from most valuable recyclables like PET bottles and aluminum cans. These go directly to store return machines instead of yellow bins. Companies raise bids for waste collection lacking those profits. Kobiór municipality hikes fees from 35zł to 39zł per person, 11% increase. Neighboring areas charge 34-44zł per person monthly. Glass waste stays with municipalities, costing 6-7 times more than aluminum to handle. Report estimates 6 billion zł losses for local governments without compensation. Private operators gain easy-recycle profits while municipalities bear heavy glass logistics. Experts warned of 20-30% national fee rises. Inflation and energy costs add to pressures. Germany achieves 98% returns after years of deposits. Finland over 90%. Mature systems cut municipal waste costs 30-40%. Ministry plans producer responsibility tweaks for balance. Glass deposits would shift costs to producers.
