BLABO® saved the Libyan desert of being contaminated by 22,000 m³ of crude oil

One tank cleaning job at the VEBA terminal at Ras Lanuf in Libya saved the desert from being contaminated by 22,148 m³ of crude oil. Instead, the terminal received almost 4 mill. USD worth of recovered oil.

BLABO® helped Libyan service provider to achieve vital goals about workers’ safety

The Libyan service provider, VAOS Ltd., had serious concerns about its workers’ safety and disposal of hydrocarbons when cleaning oil storage tanks. VAOS became the first oil cleaning and recovery service company in Libya to stop the practice of dumping excess oil into the environment.

Libyan customer received USD 700,000 worth of recovered oil using BLABO®

Zueitina Terminal received as much as USD 700,000 worth of recovered oil – oil that under manual cleaning procedures would have been dumped in desert ponds. The project was completed without VAOS workers having to enter the tank and in the end 94% of hydrocarbons were recovered.
