Paris will be testing a Morris column cleanup

Furniture experimental urban moved to Alésia (14th arrondissement) : it will capture the CO2 and produce oxygen through a tank filled with micro-algae. A carbon sink design and typically parisian.
The columns Morris have always been green. But the one that will be installed in the place Victor & Hélène Basch in the neighbourhood of Alésia in the 14th arrondissement of Paris, not covered no theatre posters. It will remain green for a good reason : it will house a culture of micro-algae, which can thrive by absorbing carbon dioxide and giving off oxygen in the polluted atmosphere of the capital.


The result of a partnership between Suez Environment and the start-Fermentalg (Gironde), this urban furniture a new genre will participate to the reduction of greenhouse gas emissions in order to “contribute to the slowing of global warming“. It is the photosynthesis of micro-algae, which will capture the carbon in this artificial well. Its designers believe that a Morris column will represent the equivalent of a hundred trees ! They hope to “provide a concrete response and sustainable within a logic of circular economy“, in the same way as other initiatives such as the recovery of energy from grey water, or the production of green energy through biomass. The two industrial partners provide the excess production of algae can be removed by the sewerage system to be treated and valued energy in sewage treatment plant sludge incineration or anaerobic digestion.


In green and against all (the gas)


The urban object has been selected to “stimulate citizen dialogue“. The advertising columns of the “ordinary” of which there are 550 in the streets of Paris, born in 1868, under the impetus of the printer Gabriel Morris, who specializes in the promotion of performances. They dot the parisian landscape in the same way as the fountains by Wallace. But the shape of the column will also be an advantage to maximise the benefits of light in the medium culture, without orientation problem, or frailty. The tank will measure 4 meters high and 2.5 meters in diameter. Fermentalg will select the strains of algae most appropriate to attach the CO2 and a portion of the nitrogen oxide (NO) produced by the automotive traffic.

The city of Paris and Suez Environnement intend to test this-column as a carbon sink for at least a year, on this road especially borrowed, a few hundred meters from the gate of Orléans, the entrance axis in the south of the capital. Bertrand Camus, ceo of Suez, France, said in columns of 20 minutes : “If this experiment proves to be effective in terms of uptake, the process could be rolled out on other areas with a high concentration of carbon dioxide gas, such as ventilation ducts car parks or on the walls of the tunnels on the device“. The section of sanitation services the city will ensure that the charged water seaweed does not generate problems at the level of the sewers. The principle of cultivation of micro-algae fixing CO2 is a promising lead already explored by manufacturers of cement, such as Calcia to the unity of Gargenville (Yvelines, france) or by architects such as X-TU. The beginnings of a city totally verdie as the imagine Vincent Callebaut, perhaps ?
