Cosmo Oil Co. has mapped out a three-year plan aimed at eradicating its industrial waste by the end of March 2005, company officials said Thursday.

Under the plan, which is already in progress, Cosmo will reduce the sludge generated by its oil refineries and other outlets by an average 81 percent each year.

After being partly dissolved with the use of microorganisms, the sludge will be incinerated, they said.

The oil company will also recycle all its office supplies and the trash generated at its offices and plants, the officials said.

Moreover, Cosmo will seek to reduce carbon dioxide emissions related to overseas oil exploration.

In the United Arab Emirates, Cosmo subsidiary Abu Dhabi Oil Co. currently places the equivalent of some 200,000 tons of carbon dioxide, generated during oil-digging activities, back into the soil without burning it, the officials said.

This practice will be extended to cover oil-digging operations in Qatar and Australia as part of the three-year plan, they said.
