Thousands of Ships Fitted With 'Cheat Devices' To Divert Poisonous Pollution Into Sea
Volkswagen, BMW, and Daimler aren't the only companies using "cheat devices" to get around environmental legislation. According to The Independent, "global shipping companies have spent billions rigging vessels with 'cheat devices' that circumvent new environmental legislation by dumping pollution into the sea instead of the air." From the report: More than $12 billion has been spent on the devices, known as open-loop scrubbers, which extract sulphur from the exhaust fumes of ships that run on heavy fuel oil. This means the vessels meet standards demanded by the International Maritime Organization (IMO) that kick in on January 1st. However, the sulphur emitted by the ships is simply re-routed from the exhaust and expelled into the water around the ships, which not only greatly increases the volume of pollutants being pumped into the sea, but also increases carbon dioxide emissions. A total of 3,756 ships, both in operation and under order, have already had scrubbers installed according to DNV GL, the world's largest ship classification company. Only 23 of these vessels have had closed-loop scrubbers installed, a version of the device that does not discharge into the sea and stores the extracted sulphur in tanks before discharging it at a safe disposal facility in a port. The Exhaust Gas Cleaning System Association has estimated that 4,000 ships will be operating with scrubbers by the time the legislation is enforced, up from fewer than a hundred in 2013. For every ton of fuel burned, ships using open-loop scrubbers emit approximately 45 tons of warm, acidic, contaminated washwater containing carcinogens including polycyclic aromatic hydrocarbons (PAHs) and heavy metals, according to the International Council on Clean Transportation (ICCT), a non-profit organization that provides scientific analysis to environmental regulators.Read more of this story at Slashdot.
