Undeveloped films contain high levels of silver and must be treated as hazardous waste. Collect and store unused film in a wide-mouthed, airtight container labeled “Hazardous Waste – Unused X-ray Film.” Once the container is full, have an approved hazardous waste transporter deliver it to an approved hazardous waste management facility.19 Developed radiographic films have little residual silver and may be disposed of as non-hazardous office waste for recycling or disposal.
