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.

チューブ型熱交換器
チューブ型熱交換器は、加熱や冷却、低温殺菌、またはUHT加熱用のすべてのプロセスプラントの中核を成しています。
デカンタ遠心分離機
懸濁液の固体成分を高効率で処理するにあたり、デカンタの時代が到来しました。この機器は、高い浄化効率性と最大限の脱水だけでなく、固体の除去と同時に液体を分離できるようにします。ここでの主な要件は高いボウル速度、巻軸の強力な駆動装置および実現される固体脱水に自動的に順応する巻軸速度です。
遠心分離機
GEA の分離機は、液体ベースの用途向けに設計されています。遠心力を利用する分離機は、異なる密度の 2 相以上で構成される懸濁液の分離に使用されます。たとえば、液体 - 液体の分離、液体 - 液体 - 固体の分離、あるいは液体 - 固体の分離に使用できます。これらはいずれも、固体を除去するときと同様、液体混合物を分離するときにも効率的です。
