which bins can take it?

  • hot pile yes
  • cold pile yes
  • worm bin yes
  • bokashi no
  • tumbler yes
  • curbside yes

why?

Manila stock got its name from Manila hemp fiber, though modern folders are simply thick unbleached wood pulp — dense, absorbent, and coating-free. That makes them clean compost fodder limited only by thickness, which tearing solves. Hanging folders add steel rods and plastic tab inserts, while colored folders use bulk-dyed fiber that breaks down exactly like the plain kind.

how to prep it

  1. Slide the steel rods out of hanging folders and scrap or trash them
  2. Pop out plastic label tabs
  3. Tear folders into strips

quick answers

Do the dyes in colored file folders matter?
