TTTU on tank cleaning and other similar projects is normally the lead contractor and as such is responsible for the management (temporary storage, waste transfer and disposal) of generated wastes and other residual material.
Historically, we utilized local disposal facilities for waste disposal. However, this proved to be a challenge based on site limitations to receiving waste generated from our tank cleaning activities. In this regard, in 2011 we investigated the BAT (Best Available Technology) for the cost effective treatment and disposal of sludge and tank bottoms recovered from cleaning operations and acquired three thermal units:

  • One Direct Fired Thermal Desorption Unit (TDU).
  • Two Infrared Thermal Evaporation units; this system has a patented system for the recovery of oil.

Our operation is governed by a CEC granted by the EMA. The units are fully commissioned and have been operational for 1-year.

Each waste stream generated must be analytically profiled prior to acceptance to confirm the anticipated disposal method and ensure that the disposal criteria are met. If elevated heavy metal concentrations are found in the waste stream an alternative method must be determined (for e.g. for solids, stabilization in a cement matrix followed by land-filling). Baseline analytical testing (full suite of parameters) will be performed on each waste stream. During the project lifetime, once the waste streams do not change, random routine analytical testing (selected parameters only) will be conducted for confirmatory purposes.

Once the waste has been successfully remediated and / or treated (as determined by analytical testing) an “End of Life” Certificate will be issued for your waste management records. This Certificate will document such information as:

  • Waste Generator
  • Waste Source
  • Date Received
  • Date Completed
  • Volume and Type of Waste Received
  • Initial Analytical Profile
  • Final Analytical Profile
