Waste to Value: How Thermal Hydrolysis with Celitron ISS AGRI Supports Sustainable Pet Food Production

04-06-2025

In the modern pet food industry, manufacturers are facing a dual challenge: meet the growing demand for high-protein pet food while aligning with increasingly strict sustainability and animal byproduct recycling standards. One often overlooked solution lies in a humble, yet abundant raw material—poultry feathers.
Using innovative thermal hydrolysis, Celitron’s ISS AGRI platform transforms otherwise indigestible chicken feathers into a highly functional, safe, and sustainable ingredient for pet food manufacturing. This technology produces rendered protein meal with high nutritional value, opening new possibilities for natural pet food ingredients.

Why Feathers? Why Now?
Feathers are a byproduct of poultry processing, rich in keratin—a structural protein with extremely strong molecular bonds. Naturally, keratin is resistant to digestion, making unprocessed feather meal an unsuitable ingredient in animal diets. However, when properly hydrolyzed, feather proteins become bioavailable and highly digestible, with significant value as pet food ingredients.

The Science Behind Thermal Hydrolysis
The ISS AGRI platform applies controlled temperature and pressure to initiate protein denaturation, a biochemical process that unfolds and reorganizes protein structures without chemical additives. Here's how it works:
• Primary Structure (amino acid sequence) remains intact.
• Secondary and Tertiary Structures (hydrogen bonding and 3D folding) are disrupted.
• Disulfide bonds, especially abundant in keratin, are cleaved, allowing the protein chains to loosen.
• The result is a protein matrix that becomes soluble, digestible, and safe for animal nutrition.
Unlike harsh chemical or alkaline methods, Celitron’s thermal approach avoids degradation of key amino acids and ensures the preservation of nutritional integrity—crucial for producing high-protein pet food that meets premium standards.

Why ISS AGRI Makes a Difference
Traditional rendering systems are often not optimized for hard-to-process materials like feathers. Celitron’s ISS AGRI system was designed specifically to tackle the most challenging animal byproducts, offering:
 Efficient keratin denaturation under thermal conditions
No chemical residues, ensuring cleaner poultry byproduct meals
Consistent protein quality and digestibility
Flexible integration into existing pet food manufacturing lines
This makes the ISS AGRI not only a rendering machine, but a sustainability enabler in the pet food supply chain.
