Computer monitor recycling should only be done by a licensed company. PC Monitors contain hazardous materials that need to be collected and disposed of safely and within the WEE directive rules for recycling electrical appliances. You can contact a company that is licensed to collect and dispose of old monitors but this is a chargeable service.
Old monitors can be stripped down for reusable scrap metal and other materials.
You can take your unwanted PC monitors along to the household waste recycling centre near you for licensed recycling. Your local tip will have a skip or container to store old monitors until they are transported to the recycling plant.
