The Essential Role of Poultry Rendering Plants

A brief introduction to poultry rendering:

  • Using a rendering process, animal waste tissue is converted into useful and valuable products. The term “rendering” refers to the entire animal’s fatty tissue. Poultry meals are made from deceased chickens, chicken faeces, tissues, and feathers. It is possible to render chicken manure from poultry slaughterhouses and processing facilities. 
  • A meal’s nutritional content might differ depending on the kind of processed raw material used. Chicken meal is a good feed ingredient that includes minerals, oils, fatty acids, and amino acids. Turkeys, ducks, and geese are included in the recyclables.

Animal byproducts are converted into high-quality protein meals using the SunRise rendering method and poultry rendering plants. Treating raw materials is the first stage in the lengthy process of turning offals into food. The most common method of processing chicken by-products was low-temperature wet rendering cooked under vapour pressure. The dry-rendering method has gained popularity and provides a dinner of superior value. Animal byproducts are prepared, pasteurized, and dehydrated to a moisture content of 8%. Yields between 10% and 12% are the optimum range for fat extraction level. The melted oil is separated from the solid proteins by pressing and draining. Clarifying oil by decanting or settling. 

Dried by-products from birds are pulverized into a powder to make poultry meat meal and feather meal. By-products from slaughterhouses may be turned into feed, which is an excellent approach to deal with the environmental issues brought on by animal waste. Environmental hazards might result from using animal byproducts. They can contaminate water, the air, and both if not managed appropriately.

What is exactly poultry rendering plants for?

The poultry rendering plants manage by-products from slaughtering birds not meant for human ingesting and converting them into useful proteins, minerals, and oils. Animals, including chickens, turkeys, ducks, and geese, are called poultry. In addition to deceased on arrival and deboning waste poultry by-products.

The leftover poultry items are all used up. However, these by-products must be processed before being employed in other operations. Using SunRise rendering methods, these poultry waste products are transformed into high-grade:

  • Animal protein meal
  • entire meal
  • Blood Meal Feather Meal
  • Fats/grease/oil

It is known as rendering to do this. These meals can be used in the feed and pet food industries. The oil, chemical, and pharmaceutical industries all depend on fats. Raw materials are handled first during chicken byproducts’ processing, then heated to remove moisture and kill microorganisms. Draining and pressing separate the melted oil from the solids (protein). The powdered solid fraction is then used to make whole, chicken, feather, and poultry fats. Clarification of the oil is possible by decanting or settling.

Benefits of Rendering for the Environment

Renderers are the first recyclers, and in talks of food and food waste, our crucial role in using ABP is sometimes disregarded. The reduction of the entire carbon footprint of the animal-based food supply chain from farmhouse to fork is made possible by treating ABP, which is essential for the sustainability of agriculture and food production. In essence, rendering involves recycling and reusing animal by-products that would otherwise need to be disposed of in a landfill.

  • Low cost: 

Since feather meal is created from waste materials rather than mined minerals or petroleum products, it is far less expensive than synthetic fertilizers.

  • Simple use:

The machine crushes the feathers, making it simple to scatter them on the ground. By doing this, there is no longer any need for clumsy spreading or mixing on your grass or garden beds.

What is used for a poultry meal?  

This food is an effective supplement to animal nourishment and a reasonably priced basis of protein. It may be fed to cows, pigs, chickens, and horses. When animals are not given extra vitamins and minerals, this is highly essential. It is a priceless component of fish and fur feed. Animal feed uses chicken meal as a source of protein. It is quite common on farms because the inexpensive meal makes it easy to improve animal nutrition. Calcium and phosphorus, which are included in poultry meals, are difficult for animals to get if they do not have unrestricted contact with pasture. Even though a meal doesn’t include all the essential minerals, it may be used as fish food for predatory fish.

How can feathers be hydrolyzed in rendering plants?  

The leftover hydrolyzed poultry feathers from the dealing out of animal corpses are ground and dried to create feather meal. Under high heat and pressure, the disinfection procedure can be completed in a batch cooker or a nonstop hydrolyzer. Pressure hydrolysis is required to dissolve the keratin, a type of strong protein bond found in feathers. The food contains amino acids that are also present in hog hair and uncooked feathers. Feathers become more digestible when the protein links are broken down. 

What is used for a feather meal?

It is a valuable protein source and a component of animal feed. It enhances the excellence of the fur and maintains the well-being of the animals. Better digestibility amongst different animal species is made possible by reduced ash content. Fish food also contains feather meal. For great greedy fish like trout and tilapia in particular, it is the best source of protein. It has a lot of nitrogen in it. A meal is a great organic fertilizer because of its component. It contains protein. Compared to a chicken meal, this meal is deficient in nutrients and may call for supplementary nutritional supplements. 


The rendering process is an important but sometimes disregarded component in chicken production. By converting chicken by-products into useful resources, poultry rendering plants are essential to the industry. But for many people, the inner workings of these plants are still a mystery. With the industry’s most advanced process and technology, more than 20 senior engineers, more than 100 senior technicians, and 20,000 square metres of standard industrial buildings, SunRise Company was recognized in 2018 as a national high-tech organization. Our team comprises young individuals with aspirations, inventions, and values.
