<p>This invention relates to a process for the recovery of blowing agents from process exhaust streams in the manufacture and recycle of foam bodies. Blowing agents are used in the production of foam bodies. In certain cases, such as when the foam is used for thermal insulation, it is desirable to produce a foam body having trapped blowing agent within the foam body's cell structure. When comminuted, these foam bodies release blowing agent. Comminution of such foam bodies may occur during the machining of the foam bodies or during the grinding of the foam bodies for recycling.</p> |
