can you compost business cards?

brown · carbon paper & cardboard

Sometimes — plain matte cardstock cards compost; the glossy, UV-coated, and plastic ones that dominate the stack don't.

which bins can take it?

  • hot pile caution
  • cold pile caution
  • worm bin caution
  • bokashi no
  • tumbler caution
  • curbside caution
  • hot pile: Matte, uncoated cards only — a sheen or slick feel means the coating will outlast the pile.
  • cold pile: Uncoated cards only, torn and buried; coated ones emerge unchanged.
  • worm bin: Torn uncoated cards are fine in small numbers; skip anything with a finish.
  • tumbler: Only obvious matte-paper cards; laminated ones just tumble around intact.
  • curbside: Coated cards slip into green bins unnoticed and end as plastic flecks in someone's garden — sort honestly.

why?

A business card is a coin-flip material because print shops finish most runs with gloss UV coating, aqueous satin, or full lamination for durability — exactly the treatments that lock microbes out. An uncoated matte card is nothing but heavy paper and rots accordingly. Between the extremes sit soft-touch and silk cards, which are laminates despite their paper-like feel.

how to prep it

  1. Sort by feel: dead-matte cards compost, any sheen or rubbery softness means trash
  2. Tear compostable cards in half or quarters

watch out for

  • Soft-touch velvet-finish cards are plastic-laminated even though they feel like premium paper.
  • Metallic foil logos are metallized plastic film — tear off the foiled corner and compost the rest if the base card is matte.

quick answers

How can I tell if a business card is coated?

Three quick checks: hold it at an angle to the light (any sheen is coating), tear a corner (coated stock resists and shows a layered edge), and drip water on it (beading means coating, a darkening soak spot means bare paper).
