Through your newspaper I would like to inform that Karachi generates 8,000 tons of garbage daily and this could be stored at dumping sites in the city, which will eventually be transferred to landfill sites outside the city.
In this regard I would like to draw the attention of the city administration towards the household garbage (organic waste) which can be converted into organic fertilisers.
Our farmland soil has depleted in nutrient elements. Now it has become necessary to add fertilizers in farms. Addition of inorganic fertiliser is proving harmful for soil, environment and consumers. It is a proven fact that organic fertiliser is better than inorganic fertiliser. This research work isolates and identifies micro-organisms which convert organic waste into organic fertiliser.
The process of conversion takes place slowly and is completed within six months.
The cost of input for creating a facility (bio-converter) for the conversion of organic waste may be initially higher than the output (organic fertilizers) but in the long run it would turn into profitable enterprise and may give rise to compost preparation industry in Karachi. The addition of organic fertilizers in farmland soil will boost up food production.
This process augurs well for dwellers as solid waste blocks the sewerage system and cause pollution of water and air. The application of composting technology in disposing of the city garbage will keep the city clean and we can hope to get clean air and water.
We in the department of agricultural at Karachi University can build up a pilot project, if we are provided with the necessary facilities, for demonstration to entrepreneurs interested in bio conversion of organic in to organic fertilizers.
