Our patented production method uses a cold hydrolysis process.
U.S. Patent # 7,678,171 B2
Canadian Patent # 2,546,156
The patented GreenStreme cold hydrolysis manufacturing method uses fresh rainbow trout heads, tails and frames to produce nutrient-rich concentrates containing all of the natural proteins, amino acids, oils and nutrients. Other fish fertilizers use a process that cooks the fish waste before extracting the oils and proteins, leaving a thick brown liquid void of the valuable attributes in the GreenStreme Hydrolysis process.
