Oily waste is being consigned as..

• European Waste Catalogue
• 16-07-08M - wastes containing oil from transport
  tank, storage tank and barrel cleaning
• 01-05-05M -oil-containing drilling muds and
  wastes
• 01-05-06M -drilling muds and other drilling
  wastes containing dangerous substances
• i.e. hazardous, mirror entry wastes

But the reality is.

• Oily wastes at the quayside also contain
• 13-05-01 A -solids from grit chambers and oily
  water separators
• 13-05-02A sludges from oil/water separators
• 13-05-03A interceptor sludges
• 13-05-06A oil from oil/water separators
• 13-05-07A oily water from oil/water separators
• 13-05-08 -mixtures of oily wastes from grit
  chambers and oil/water separators
• 13-04 A Bilge oil
• i.e absolute, hazardous wastes
• So, if cant exclude absolute wastes, have to
  consign as absolute wastes

Implications

• Hazardous wastes distance 80 disposal
• Hazardous monocell unknown treatment
• Non-hazardous 40 more treatment
• At best, oily waste is a mirror entry hazardous
  waste
• Non-hazardous status not available
• Treatment COULD render mirror entry waste
  non-hazardous

Is 19-02-05M waste hazardous?

Cordah Research results-pretreat

• carcinogencity of hydrocarbons derives from
  polyaromatic hydrocarbon compounds (PAHs)
• hydrocarbons present in the wastes under
  consideration are extremely low in such PAHs and
  hence are not carcinogenic.

Conclusions

• EWC codes have gone from guidance to legal
  definitions
• Extreme care required in selection of codes
• Stabilisation not available for reduction of
  hazard
• Pretreatment (Physio-chemical) allows mirror
  entry assessment to remain
• Further solidification of sludges with cement
  reduces hazard
• Cement solidified waste probably non-hazardous
