      Chemicals, like other types of waste, can be harmful to human health or to the environment, either immediately or over an extended period of time. Chemical waste, like other hazardous waste need to be treated, disposed of, or recycled, safely.
      We advise that you should make yourself aware of local waste guidelines on chemical disposal as these rules differ per region, we also advise you to visit the Environment Agency website for further information on chemical disposal.

      Remember NEVER mix any chemicals!

      Alternatively you can ship used chemicals back to us and we will dispose of them for you. If you wish to do this please contact us at sales@crownhill.co.uk to make the relevant arrangements.


      Disposal of Aqueous Waste Down Drains

      No waste should be put into the drains unless the user knows that it is perfectly safe to do so. Such waste must not damage the environment, the sewerage system, or the health and safety of the public.
      As outlined in the guidelines, to achieve this, the waste:
      1. Must not be harmful.
      2. Must not be flammable or explosive.
      3. Must not be corrosive – pH between 6 and 10.
      4. Must not kill or feed bacteria – usually achieved by limiting the quantity of material


      It may sometimes be acceptable to dispose of hazardous chemicals in very dilute solutions into the drains, particularly if the amounts are small, and accompanied by large quantities of water.


      Disposal of Solvent Waste

      Hazardous solvents should be disposed of through a recognised chemical hazard disposal route appropriate for hazardous chemicals. Solvent waste disposal bottles should be plastic coated, to limit damage in the event of explosion or impact, and also have fully vented caps to prevent pressure build up.
      Fume cupboards must not be used for disposal of volatile solvents, which simply transfers the problem to another location. Solvents should not be put down the drains - they can “reappear” elsewhere in the system, causing risk to other people.
