PFAL/TWI is very far from being "inert." It 'erts people all the time, in so many ways.
And like cellophane, or any other form of plastic round the face, we know how suffocatingly dangerous it can be. And by and large it's unrecyclable. Just like most of PFAL is unrecyclable into either its constituent parts or into use elsewhere - in life or church settings. It's just landfill waste.
