AP-42, CH 11.30: Perlite Processing

11.30 Perlite Processing 11.30.1 Process Description 1,2 Perlite is a glassy volcanic rock with a pearl-like luster. It usually exhibits numerous concentric cracks that cause it to resemble an onion skin. A typical perlite sample is composed of 71 to 75 percent silicon dioxide, 12.5 to 18.0 percent alumina, 4 to 5 percent potassium oxide, 1 to

Perlite - an overview ScienceDirect Topics

Being an inert material, recycling perlite poses no environmental problems. Re-using perlite without processing to grow successive crops is potentially risky because of media compaction, salt build-up, and pest contamination (Hanna and Smith, 2002). Replacing used perlite with new media to raise successive crops is costly, and recovering the ...

soil - Perlite and Vermiculite sustainability - Gardening ...

perlite and vermiculite are both mined and then heated, so it's sustainability is suspect. perlite industry says they offset carbon processing, which means they're not 100% green. they also say there is plenty and we will have it for generations to come, but that means it's finite and if you're looking into regenerative agriculture it is still taking resources away from the earth.
