Vetiver Grass in Vertical Carbon Sequestration

Saturday, April 20, 2013



I am sure that you have heard me say before that we have only just started to discover the many applications where vetiver grass can make a significant contribution to improve land, air, and water environmental problems. This excellent article, VetiVertical City in Shanghai, China, published online by Architect, the magazine of the American Institute of Architects, opens the floodgates to the possibility of urban installations where vertical fields of vetiver can play a role cleaning the polluted city environment.

Granted, this comes directly from the Easier-said-than-done Department and it is still a conceptual proposal by italian architect Eugenio Aglietti. Nevertheless, seeing a detailed presentation like this (note that there are 12 pictures in the scrolling photo strip) means that architects, engineers, and city planners have taken notice of the possibilities offered by our favorite plant.

The article tells us that Shanghai is one of the Chinese cities with the highest levels of CO2 emissions per capita and held the lead as the biggest carbon dioxide emitter between 2004 and 2007. Could we ask for a better testing ground?

In a previous article in this blog in 2009, Vetiver in Carbon Sequestration, I discussed some of the early research using vetiver for this purpose. It seems that the idea is now moving from research to reality. The article estimates that 4,000 billion Vetiver plants all over the world would be needed to handle the global excess of CO2. Let's get to work!
