Poland starts nationwide deposit-return system on October 1 2025. Goal is boosting recycling of beverage packaging. Sellers add deposits to select single-use containers. Customers recover deposits by returning marked packaging. System first covers PET plastic 0.1-3L, metal cans to 1L, single-use glass 0.1-1.5L. Multi-use glass bottles to 1.5L join January 2026. Small glass alcohol bottles under 200ml fully excluded. Małpki are single-use glass unfit for system. Logistics costs for tiny bottles too high. Small shops cannot handle volume of heavy waste. Milk and dairy packaging excluded entirely. Dairy spoils fast breeding bacteria mold and stench. Covered packaging shows special codes and deposit amounts. Compromise prioritizes small shops for system accessibility.
