“In a lot of ways we’ve used this machine like a yard crane. In addition to all of the digging and rock moving we were able to lift a telephone manhole weighing 8.2 tons a total of 22 feet out of a hole. We also had the Liebherr plumbed with a hammer and used it for demo work in early phases of the job. The articulated bucket made the Liebherr an excellent tool for grading,” Roberto said.

Dündar said the project has been at peak levels since breakwater construction and would remain so during the two-and-a-half month dredging period which started last week. An extra 30 specialist personnel have been brought in to carry out the work, pushing the total workforce to just over 300. The basin will be dredged to a depth of -5m, with the removal of existing sea bed materials equating to 300,000m³.

In 2005, Chevron Nigeria Limited established the Itsekiri Regional Development Council (IRDC) and disbursed N7.2 billion to it for the development of 24 Itsekiri communities. Eighteen years after, Itsekiri land is still in shambles as money disbursed by Chevron seems to have gone down the drain.

Also deployed were giant rubber bag “geotubes” to dewater the waste and capture more solids — although Jarjour told NVN this month the bags are no longer used because they were a “temporary measure to treat accumulated biosolids.”

“We’re hoping that the requirement to monitor and [potentially] clean up groundwater after closure would influence companies like Dominion to remove the waste,” said Lisa Evans, senior administrative counsel for Earthjustice, a national environmental group involved in the settlement. The alternative would be removing it to a landfill lined to prevent leakage into groundwater.

The team had given Slat’s invention a name, Wilson, for the volleyball that Tom Hanks, lost at sea, befriends in “Cast Away.” Slat held a brief press conference, concluding, “For sixty years, mankind has been putting plastic into the oceans. From this day onward, we’re taking it back out again.” The ferry set off, and a few minutes later Wilson came into view, gliding behind the Maersk ship like a long black tail. It was already speckled with bird droppings.

Scientists have been experimenting with bacteria to quicken the extraction of jute and improve the quality of the fibres to yield softer fabrics. A special digital printing technique developed in the lab could allow jute to replace plastic in banners and advertisements, the researchers say.

Using the permeable fabric in overlays rather than a one-inch layer of asphalt saves contractors and state agencies time and money, he and other experts say. It’s an application that’s easy to learn, and state highway departments such as the Minnesota Department of Transportation are researching how to optimize use of these fabrics.
