The Hazardous Waste (England and Wales) Regulations 2005 were amended on 6 April 2009 and organisations that produce hazardous waste are now exempt from registration if no more than 500kg of hazardous waste is produced in a year. The changes only apply to England; the Welsh Assembly is still considering what action to take.
The materials classified as hazardous are identified by the European Waste Catalogue and were updated in July 2015. These include fluorescent tubes, lead-acid batteries and some printer cartridges. It is worth noting that Kyocera toner cassettes, because they contain no dangerous substances, are classified as non-hazardous (the classification is 08 03 18).
If your organisation produces more than 500kg of hazardous waste per annum, it needs to register as a hazardous waste producer. Any contractors who dispose of these items on your behalf will also need to be registered. You can find details of your obligations here.
