While this product is a step in the right direction (as is dismantling windmills for parts and raw materials to build nuclear power plants), the best method is still to nuke the site from orbit.

This method is especially effective is very high density blue voting districts where collateral damage will be kept to a minimum.

After all, it's the only way to be sure.
