London has had an air quality problem for a long time and now they may have finally found a way to combat air pollution. They are not going after the sources, but rather trying to capture the pollution by spreading “pollution glue” or calcium magnesium acetate on the city’s roads. It’s a novel idea that just might work. After all, you are only limited by the amount of road that you have.
The idea is that calcium magnesium acetate would glue particles to the roadway to stop them from re-circulating into the air. First, they will sweep and wash the roads, then apply the solution using a modified winter gritting machine with a fine sprinkler-like system.
It’s a good plan, but until they tackle the sources as well, they may never get ahead of the problem. The first trials are underway at the Mercury Way industrial site in Lewisham and Horn Lane in Ealing. More trials will start in early 2012.
