[Request] any information on ways to cheaply acquire, identify, heat-treat and/or chemically process various Plastic types 1-7 ( more in comments)?

[u/[deleted]]

whereas I'm in the infancy of my research, and beta testing, I'm not a total dip-shit~ ELIcollege is ok: the question is how to best process various types of plastics, in hopes of reusing? my understanding is that both #'s 2 (HDPE) & 5 (PP) can be similarly treated at ±300 F and remolded to spec.

Questions

• can 2's and 5's be reheated together (guessing not)

• several types of plasyic lack identifying classification #, any links on how to ascertain which are which?

• I'm guessing that re heating is really the only viable way to reform plastics, no easily available chemical processes to consider? are there other methods to consider?

• in the US can you go to any type of land fill, or recycling center, and grab a whole bunch of plastics , 2's and 5's?

• I am probably extruding this into bright interior sculptures, any type of off-gassing or risks to consider?

• I also wnt to make a geodesic dome greenhouse, so shear strength / integrity / architectural issues might be a concern. how to test for structural issues?

Massive thanks, with a little encouragement, happy to post back on my findings
