(iii) A second layer of mixed refuse is spread over the first layer, till the heap rises about half a metre.

(iv) The set-up is kept undisturbed for about 3 months, during which water is sprinkled over it at regular intervals.

(v) A trench is then dug, its material is taken out and rearranged in conical heaps and covered with a layer of soil.
