There are several types of slaughterhouses, including:
Modern abattoirs
These are the most advanced slaughterhouses, with industrial-scale operations that include cold storage, processing, and waste recycling. They are often built and controlled by central governments with foreign assistance
Simple slaughterhouses
These slaughterhouses perform a limited amount of by-product processing, and their main products are fresh meat.
Complex slaughterhouses
These slaughterhouses perform extensive processing of by-products, such as rendering, blood processing, and hide and hair processing.
