This invention relates to a process for the preparation of digested organic supplements (DOrS) and an apparatus therefore. Composting of the raw material like agricultural waste and poultry droppings, mushroom spent waste, rock phosphate and other garvage, is as such known in the art. The composting process comprises in dropping the agricultural waste or other qarvaqe into a pit or in the form of a heap which is being allowed to be decomposed to a natural manner. The other process is a mechanical composting wherein the raw material is passed through a mechanical device consisting of maqnets and conveyor belt to separate out metallic objects from the agricultural waste or other qarvaqe. The waste after removing the metallic objects is subjected to the step of crushing so as to get powder which is sieved and packed. There are disadvantages associated with the process as such known in the art. The main disadvantage is that the technology is of high standard and the initial investment is high for a small volume of compost product ion. Another disadvantage is that the skilled persons are required to operate the plant and the maintenance thereof is very costly. Yet another disadvantage is that the cost of the product prepared by using th* conventional technology and apparatus is very high. Still another disadvantage is that decomposition of the raw material is incomplete and also th* process is time consuming. Still another disadvantage is that the conventional process produces pollution to the en v i r on men t. Still further disadvantage is that the final product (compost) is of a poor quality and contaminated with harm and humane* pathogens which causes harm.
