PROCESSING OF MEAT, BONES AND OFFAL

From an economic point of view, it means turning waste hazardous to health and expensive to manage into a valuable component for compound feed and other industries. RENDERING can improve the operating account of slaughterhouses because it generates income and saves the cost of waste disposal. It can also be the main activity of companies that collect animal waste from others such as small slaughterhouses, butchers, or canneries.
