[greenyes] Re: Plastic Bottle frustrations


Sealed PET bottles are indeed a hauling and processing problem. It
takes over 120 psi across the platen for a baler to begin cracking PET
bottlenecks, and even then, intact "bottle balloons" are commonly seen
in high-density bales from two-ram balers. There have been several
commercial machines offered, such as Marathon's Rotary Recycler, but
they were so expensive as to preclude their use for anything but
high-volume destruction of off-spec beverages. CP Mfg. offers the
PF-1500; scaled for the individual sorting station at a MRF, as well as
much larger units, and REM sells their Perf-5
http://www.remfg.com/perf.htm#p5 . However, none of these seem very
practical to mount on a truck. On-board plastics compactors for
curbside sort trucks were tried and have fallen from favor for good
reasons- inability to burst closed PET being one of them. One vendor
offers a specialized truck-mounted vacuum-fed auger for plastics
collection that claims 8:1 permanent reduction.

Rural and nonprofit recyclers have applied their unique ingenuity to
this problem over the years, one OSHA UNAPPROVED method that comes to
mind involved a Skilsaw strapped inline to a PVC pipe.......

Especially with regards to the aforementioned method, no listing herein
should be construed as an endorsement!
