In at least one specific embodiment, the process includes preparing a mixture comprising the one or more monomers, a catalyst system and a flourinated hydrocarbon, preferably a hydrofluorocarbon. A fluorinated hydrocarbon containing stream, a polymer product stream and a waste stream are recovered from the mixture. At least a portion of the waste stream is sent to a non-flare decomposition system to produce a destructed waste stream, and the destructed waste stream is released to atmosphere.
