Disposal of wastes containing chlorinated paraffins

There are three possibilities:

  • resource recovery (reuse/recycling or recovering of energy by incineration)
  • destructive incineration
  • landfill

For more information about those three possibilities, see the  Impact of chlorinated paraffins in recovery/disposal process page

Each type of waste may be safely managed by one or more of these techniques. Recommendations are as follows (local regulations should be consulted to ensure compliance):

Solids

  • C10-13 liquids adsorbed onto solids - Hazardous waste landfill or Incineration.
  • C14-17, C18-20, C20-30 solid and liquid CPs absorbed onto non-combustible solids - Landfill.
  • C14-17, C18-20, C20-30 solid and liquid CPs adsorbed/ absorbed onto combustible solids - Incineration or landfill.
  • Metal swarf with CPs - Incineration/re-smelting or Degreasing/separation from solvent or Incineration.

Oil based liquids

  • Used oil from metal working operations - Recovery (restrictions in Germany) or Incineration.
  • Mixed plasticiser condensates - Recovery/deodorisation/re-use when feasible or Incineration.
  • Unusable liquid CPs - Incineration.

Water based liquids

Emulsions and mixtures should first be split into oil and water phases. The oil phase should then be disposed of by incineration. Three techniques can be utilised in the splitting process producing split waste of differing quality.

1. Chemical splitting

This gives split water with high salt contents and imperfect oil separation so that further treatment is required. The oil phase also is contaminated with chemicals, water, etc. and is consequently treated as "hazardous waste". Mineral oils can also be carcinogenic.

2. Aqueous evaporation

The water is evaporated and when condensed often requires no additional treatment (unless contaminated by volatile substances). The oil phase can be disposed of by normal incineration/energy generation (according to calorific value).

3. Ultrafiltration

The separated water may need some additional treatment e.g., to reduce Chemical Oxygen Demand (COD). The oil phase can be treated as given for "aqueous evaporation".

Sludges

Three phase mixtures (oil, water and solids) of this type are best disposed of as hazardous waste by a specialist contractor. Alternatively a combination of the above separation processes may be employed by large companies with their own facilities.
