Hello PP Community, I am about to separate shredded LDPE and PP. Is there a household way to do it without going thru the vegetable oil float test? I am trying to avoid it as much as I can as it will be another process to clean the oil afterwards. Background: These plastics have no markings on them. I did my best to separate them visually and by feel. So my plan was to shred them all together (by color) and then sort it out through the float test and/or other means. I am half way there as most of it floated with the water test (HDPE, LDPE, PP). Next will be the alcohol test, which will separate the HDPE. Which leaves me with the LDPE and PP combo. Hoping to hear some advice soon. Many thanks!
