NERDC has worked on the manufacturing of a domestic shredder as a result of the choice of an appropriate technology. Based on the ground surveys carried out in relation to the required machinery for the process of manufacturing organic fertilizer, it was proved that although few large-scale machines are imported, there is a considerable demand for domestic and medium-scale machinery. Those three kinds of machinery are domestic-scaled shredding cum pulverizing machines, medium-scaled shredding cum pulverizing machines.
