GRANFONDO features

Physical state: friable flakes, with thickness between 2 and 3 mm, with a less than 10mm mean diameter

Main components: dehydrate calcium sulphate, stabilized organic matter, hydrolyzed organic matter

Organic substance: it is constituted by two types of selected biological materials:

  • Biomass hydrolyzed by chemical way, without heat
  • Biomass aerobically stabilized
