Technology:

Architect Dan Roosegaarde and nanoparticles expert Bob Ursem created a smog filter that uses ion technology to ingest dirty air,  filter it, and return clean air through vents. The filter is installed in a  7meter high steel tower that can be easily shipped. Initially installed in Rotterdam, expansion plans include Beijing, whose pollution inspired the product’s design. The filter has the capacity to clean 30,000 cubic meters of air in an hour. The air space roughly the size of a football stadium could be filtered in 1.5 days. The tower is also energy efficient running on 14,000 kilowatts of power. In Rotterdam, it is powered by wind and will potentially be powered by solar in other cities.

Sustainability Problem:

Air pollution causes nearly 3 million deaths per year and is expected to get worse, especially in developing countries, if steps to resolve are not addressed. The filtering towers will not solve the problem completely, but it is a good concept to increase awareness of air quality conditions and encourage wider air pollution reduction measures.

Stakeholders:

  • Governments in cities/countries with poor air quality
  • Citizens in cities/countries with poor air quality
  • NGOs
  • Scientists/Engineers
  • Architects/Urban Planners
  • Investors

Implementation:

  • Initial funds were raised on Kickstarter
  • Plan is to implement in public parks in Beijing with leasing options available to keep costs down
  • Potential expansion to other countries that face air quality concerns such as India
  • Public-Private Partnerships would be key in implementing on larger scale and to help cities with the costs

  1. Thanks for sharing this technology! Do you think that a factor that needs to be considered here is the look and amount of space that these towers take up? I think a hurdle that will have to be overcome in implementation of these towers would be to get buy in from cities that these towers will provide more good than harm from a visual perceptive. I worry that some will shoot down the idea because they do not want their cities skyline to be covered in filtering towers.

  2. This is very cool technology. I am curious about how it cleans the air. The fact that it is scalable and can be implemented in places where there is limited green space makes it an interesting solution. Although the it seems to be energy efficient, it would be better to partner this with a renewable energy source or the power generated to run it will cause the problem it is trying to solve.
