@deckingman thank you for the link the article is good as a start, and interesting in respect of other aspects like acetone.
I hoped someone has personal experience how many times recycling is possible.
Experience with factors like:
contamination
decomposition at higher temperatures *)
effects of the colors
effects of water content
how to separate plastics by spectroscopy, density
are other thermoplastics better suited
*) is it 0% if staying at normal melting temperature, or is it e.g. 5%, which limits the number of cycles it can be recycled?
