In many cases, such as the one described in this post, the manufacturer will cover the cost to have the unit returned as it is crtiical for them to determine the cause of the failure and risk involved. This leads to better, safer products in the long run. UL and CSA labs may also be interested.
For disposal of a unit that fails safely, many stores (such as home depot I believe) offer a recycle box specifically for CFL so that the mercury and other elements can be safely extracted.
