Waste: Eldorado for port cities?

 Energy transition and circular economy 

Industrial ecology is a means of pooling and recycling emissions from industry to assist other companies and focus development on a virtuous circle. Port Salford in Greater Manchester (UK) is set to be extended using recycled construction materials, avoiding a significant amount of pollution that would otherwise be generated by concrete production. This port development mirrors other urban initiatives, including one in Brussels (Belgium), where city hall has selected 38 projects. These will also be actively supported by the port, which is providing land to store the recyclable materials. However, the idea is not limited only to European countries. Kenya has signed an ambitious partnership with the firm ENI to convert agricultural waste into biofuels in Mombasa, the country’s largest port city.

Marine cooling solutions and renewable energies for more environmentally friendly data centres

 Energy transition and circular economy 

Port cities, with their maritime location and characteristic urban fabric, are at the cutting edge when it comes to the development of data centres, a key part of the big data revolution. Google’s biggest data centre is in Hamina-Kotka (Finland), where the company has triggered a rush of investment in marine cooling systems.  These involve using seawater to reduce the amount of electricity required to power cooling systems, and could be the way forward. A similar approach has been adopted in Marseilles (France), where two data centres are set to be temperature controlled using a “river cooling” solution with water taken from the port dock basins. Another option is to bring the data centre to the sea, rather than the other way around. In the Orkney Islands (UK), Microsoft tested a data centre submerged in the North Sea. The experiment was a complete success, using six times less electricity. Finally, the power needed to run data centres could be generated in a more environmentally friendly way by capitalising on the potential of port cities. In Dakhla (Morocco), a 900 MW wind farm will soon be powering a 100% green data centre.
