Chemical Composition

Elemental breakdown by percentage weight.

Standard composition limits
Values represent maximum allowed percentage unless otherwise noted.

Physical Properties

Material form, density, and contamination specifications.

Post-use silver-bearing photographic/radiographic waste; outdated photographic film (35mm, 120mm, large format), expired X-ray films from medical facilities (hospitals, dentists, veterinarians), radiographic inspection films from industrial applications; established precious metal recovery infrastructure; moderate silver concentration; specialty recycling stream with environmental/medical waste considerations

Acceptable Inclusions
  • Silver 1-3% (film specification)
  • Gelatin emulsion 0-50% (binder)
  • Polyester/acetate base 0-40% (substrate)
  • Organic dyes/sensitizers 0-5% (color components)
  • Hardening agents 0-5% (processing chemicals)
  • Inert fillers/anti-curl agents 0-5% (substrate additives)
  • Chemical residue from developing (fixer, developer; acceptable trace)
Prohibited Materials
  • Silver <1% (below specification)
  • Formaldehyde >0.1% (hazmat exceeds; health concern)
  • Unknown processing chemicals (hazmat uncertainty)
  • Contaminated with heavy metals (non-standard waste)
  • Mixed paper-based prints (cellulose paper instead of polyester)
  • Severely degraded film (no recovery value)
