I am not sure if any of you can address this issue, but TechNet seemed
to be a good place for forwarding this message.

Subject: Printed Circuit Board Lamination Process

Subject: Printed Circuit Board Lamination Process
A Printed Circuit Board company is looking for ways of eliminating,
recycling or at least reducing two wastes generated during the lamination
process. They are looking for a use for the edge trim which is generated
during the process. About 2 million pounds of edge trim are generated at
their facilities worldwide each year. The composition of the edge trim (in
weight %) is:
Continuous Filament Fiber Glass 40-70%
Epoxy Resin 30-60%
DMF (Dimethyl Formamide) 0.0015% (1500 mg/g)
They are also looking for ways of eliminating, regenerating, or recycling
the resin mixture left at the end of the process. This resin solution
contains a glycidyl ether of brominated bisphenol A, acetone, epoxy resin,
dimethyl formamide, phenyl glycidyl ether, amyl alcohol, and epichlorohydrin.
Thank you,
Marc
