Re: Re: [papercreters] Tetracrete

If I recall correctly, Tetrapak is the collapsable drink packaging that is generally made from laminated layers of paper, plastic, and aluminum foil.  It has also been recycled to make decking boards.  It is used for everything from kiddie juice boxes to UHT milk.

I did some experiments with tetrapak papercrete, and the results are good. The resulting papercrete was every bit as strong as ordinary papercrete, and was prettily speckled with little bits of non-pulpable outer layer of carton.

BUT getting these things to pulp is very difficult. The little mixer I've been using for test samples didn't even begin to do it, even after an overnight soak. The only way was to cross-cut shred the tetrapak first, then the mixer would do it - but only with a real struggle and a very prolonged pulping time.
