KEY WORDS: Ecological Footprint (EF), Sustainability, Khulna City Corporation (KCC).
Waste is directly related to the consumption of food and dumping to the land. Ecological footprint makes a relationship between two factors- the amount of land required to dispose per capita generated waste. Alike all municipal corporations around the world, Khulna City Corporation (KCC) face lack of waste dumping area with its increasing urbanized wastes. In this concern, the research has to calculate the ecological footprint to develop a sustainable waste management for waste generation in KCC considering its existing solid waste characteristics. Characteristically, KCC area is a naturally productive zone, because the income level of its population is not up to the mark. Although the city managed by unplanned way, it has potentiality to be developed in planned order through the estimation of ecological footprint for waste generation. The research reveals that the ecological footprint of waste generation in KCC area is significant. Because per capita waste generation in KCC area is 0.5 kg/capita/day or 455 tons/day, of which organic waste is 78%, paper 11.5%, plastic 5%, glass 4.7% and metal 2.8%. To assimilate of these components in its generated waste required 0.088 hector land per capita consisting of 152.85 m2/ capita for paper, 43.32 m2/capita for plastic, 19.31 m2/capita for glass, 46.73 m2/capita for metal and 624.30 m2/capita for organic waste composition. Considering the land categories, 775.86 m2/capita and 96.76 m2/capita energy accumulative and built up lands required for assimilating the total generated waste in KCC area respectively. These lands requirement are directly related to the recycling rate of wastes. The analysis reveals that the ecological footprint provides on the basis of waste management practices. Finally the research recommends that the ecological footprint could be used as a sustainable waste management tool for KCC and other metropolitan cities of Bangladesh environmentally friendly sustainable waste management.
