| Coir pith hillocks are
common in the neighbourhood of fibre extraction units. A
novel technology of composting these hillocks has been developed
by Coir Board. There is an accumulation of about 1 million MT of
coir pith in our country mainly in the states of Kerala and
Tamil Nadu. The composting process can be carried out on
the hillock itself by digging a pit of 3 ft.dia. and one meter
depth. The pit is refilled with the excavated coir pith
mixed with PITHPLUS, urea and calcium carbonate in the
proportions based on the dug out material. Before refilling the
pit, the aeration pipes are laid on the bottom of the pit in a
manner that can house 19 perforated PVC pipes
systematically. All the PVC pipes are connected from the
bottom with 2" non-perforated PVC pipes which are protruded
outside the heap in order to enable flow of air into the
heap. This method has brought down the composting period
from 30 days to 21 days only. The process saves the labour
shifting the position to another place as well as the space that
was required to lay the composting heap in the conventional
process |
