Rendering Industry has emerged and developed over time in order to process the parts which are served to the table of the consumer and recover these parts for the economy. The rate of consumption of slaughtered animals changes from country to country according to differing habits of various cultures. This corresponds to almost one third of the slaughtered animal in the western world (solely in the United Kingdom 1.75 million tonnes of animal products comprise 250,000 tonnes of fat and 400,000 tonnes of animal protein).
Rendering Process comprise of crushing and grounding animal by-products, followed by moisture removal and cooking in order to eliminate microorganisms. The process of separating melted fat (tallow) from the solids (protein) is performed by centrifuge (spinning) or pressing methods. The remaining solids are then ground into powder as meat and bone meal.
While rendering has been a regular and ordered industry for only 150 years, the process of melting animal fat to produce tallow and other fat products has begun by people cooking food over camp fires and gathering the dripping fat. Historians have depicted the process of producing soap and candlewax as products of rendering from a letter narrating a Roman soldier’s first attempts at rendering.
Today, this industry makes great contributions to the efforts to maintain a clean and healthy environment. In addition, rendering facilities convert normally unusable by-products into usable and commercially valuable goods like tallow and some chemicals used in soap production or animal protein products for animal feed production.
The latest technologies, strict regulation and a real feeling of loyalty and responsibility against the environment make today’s rendering facilities into operations which use most advanced technologies and require very high investment.
