Hello! I’m fairly new to the photo lab. I’d like to use selenium or sepia toner – for the colour and the archival quality. But once the toner’s been used up, where do I take it? What should I do with the old toner?
Here, you can dispose of chemicals up to 5 litres in the hazardous waste collection van. Your local waste disposal service can provide you with further information.
