The best way to prevent food loss and waste is to utilize everything
Animal fats and proteins
Around 50 percent of an animal raised for meat production cannot be consumed directly. Among those co- or by-products are fats, bones, blood, leftover meat, feathers and some internal organs.
GEA offers key expertise and technologies to process these resources into valuable food or non-food products like oils and fats, protein hydrolyzates, collagen, gelatine and other ingredients for food, petfood, feed or biofuels.
Animal by-products processing
The other 50 percent: processing animal by-products
Processing the co-products or by-products from livestock breeding is not only economically reasonable, but also highly sustainable and can be seen as true recycling. Without rendering roughly 50 percent of every meat animal would be wasted, valuable resources lost with an enormous strain on our waste management systems as well as the environment.
In Europe alone roughly 18 million tons of animal by-products are collected from the meat and livestock industry each year and processed into valuable resources for food, feed and biofuels (source: EFPRA). In North America the rendering industry divert 62 billion pounds of food waste from landfill recycling these raw materials into 29 billion pounds of fat, oil and protein (source: NARA).
GEA has the right technology and expertise to help processing animal by-products into valuable food, petfood or feed ingredients or into feedstock for biofuels like HVO or SAF.
Thus, the food processors and renderers play an important part in our economies and societies: they take care of the proper management of by-products but also fallen animals to prevent health and food risks and they save millions of tons of valuable resources every year from becoming food waste.
Processed animal by-products - what are they used for?
In principle, proteins and fats can be extracted and purified by further processing from animal by-products, which are then used as ingredients or feedstock for
- Food
- Pet food
- Livestock, poultry feed
- Aquafeed
- Fertilizers
- Oleic acid, glycerin, stearic acid, linolic acid
- Biofuels, i.e. HVO (hydrated vegetable oil) or SAF (sustainable aviation fuel)
Whether on the plate or in the tank, rendering options are diverse.

Décanteur centrifuge
Le décanteur est appelé à intervenir dès que la teneur en matières solides dans la suspension à traiter atteint un niveau particulièrement élevé. Ces machines offrent l'avantage d'un rendement de clarification élevé et d'une déshydratation optimale, et assurent en outre la séparation des liquides tout en éliminant les matières soli...
Séparateur centrifuge
Les séparateurs de GEA sont conçus pour les applications à base de liquides. S'appuyant sur la force centrifuge, ils sont utilisés pour séparer les suspensions comprenant au moins deux phases de densités différentes. Ils peuvent donc être utilisés pour la séparation liquide-liquide, la séparation liquide-liquide-solide ou la séparation liqui...
Échangeurs de chaleur tubulaires
Les échangeurs thermiques tubulaires sont au cœur de toutes les installations de process permettant de réchauffer, de refroidir, de pasteuriser ou d’effectuer un traitement UHT.
