All Grena products are obtained in the same way: organic animal residues of fish, rabbit and poultry are heat treated.
The thermal hydrolysis of the proteins is our production's core business and it takes place during the 130° cooking process.
Through the thermal hydrolysis of the proteins, naturally contained in large quantities in the organic GRENA matrix, the products obtain amino acids and carboxy groups (EDTA).
In parallel, the production of our liquid biostimulant starts here. IDROGRENA is obtained thermal extraction of the humidity contained in the slaughter waste without the addiction of any chemical. The distillation so obtained contains the organic polyamines which were inside the amino acids in the first place.
