Technology That Can Save The Great Barrier Reef




Most probably you heard that there is a green light for a major expansion of the Australian port of Abbot Point, and that it will become the world’s biggest coal port. Constructing this port will include the removal of around three million cubic meters of seabed which will be dumped in the area of the Great Barrier Reef World Heritage.
To give you an idea of the scale of this dredging, if all the dredged material were dumped on land, the pile would be bigger than the Great Pyramid of Giza. The Great Barrier Reef is one of the finest tourist attractions in Australia (generating a revenue of $5.7 billion annually), and dumping such a huge pile of mud in this beautiful national marine park could very well threaten the World Heritage listing of this unique region.
But there are alternatives to dumping the spoil!

The valuable technology using geocontainers for dewatering the sludge of Abbot Point harbor by Dutch textile technology corporation TenCate could take care of the dump. The system works with TenCate Geotube containers, tubular, permeable high-end geotextiles, that are all over the world utilized as an innovative and sustainable solution for dewatering contained solid waste from lagoons, ports, rivers and canals. The process is quite simple: the (contaminated) sludge is pumped into the TenCate Geotube containers. Environmentally safe polymers are added to the sludge, which make the solids bind together and separate the water. The cleaned water can seep out into the surface of the port while the solid waste is securely contained within the geocontainers and easily stored on the local premise or removed and transported for disposal or further treatment. A sludge filled TenCate Geotube can also be used for local coastal protection. Volume reduction can be up to 90%

Although this innovative technology was used on more than 2000 locations worldwide, it is still relatively unknown. This might explain why nobody mentioned it as the alternative to dumping the spoil within the Great Barrier Reef area. We can save the reef if we spread the word about this solution, please share this infographic and let’s save the reef. It’s a miracle world!
