which bins can take it?

  • hot pile yes
  • cold pile yes
  • worm bin yes
  • bokashi yes
  • tumbler yes
  • curbside yes
  • cold pile: Fork it through the pile instead of leaving a single dense brick.
  • worm bin: Excellent worm food in thin layers; let the bin clear each one before the next.

why?

Juicing carries off the sugars and much of the soluble nitrogen, leaving finely shredded fiber that lands a notch higher on the carbon scale than the whole produce it came from — still a green, but a fibrous one with enormous surface area. That fineness is the catch: damp pulp compresses into a dense, airless brick. Forked through shredded paper or dry leaves, it heats a pile noticeably fast.

how to prep it

  1. Mix pulp roughly 1:1 by volume with shredded paper or dry leaves
  2. Spread in thin layers, never one wet brick

quick answers

How much juice pulp can I add at once?

A quart or two mixed with equal browns per week suits a typical backyard bin. Daily juicers should split pulp between the pile, a worm bin, and the freezer to avoid matting problems.

Does citrus pulp need special handling?

Not outdoors — piles handle citrus fine. In worm bins keep citrus pulp an occasional treat; the peel oils and acidity bother worms in quantity.
