Waste generation is increasing with the increasing of population at Mymensingh city. It needs to spend money though current waste management practice of Mymensingh is not scientific. The present study was conducted to find out the profitable opportunities for municipal solid waste (MSW) management of Mymensingh city. Both primary and secondary sources were used to collect data as fulfillment of the study. Twenty two (22) different locations from 21 wards in the city were visited for collecting these data. In the city, estimated amount of waste were 150 tons/day, where 40-50% biodegradable and 15-25% recyclable paper, plastic, glass, metal etc. Currently waste are not being collecting and disposing scientifically due to unavailability of facilities, thus creating environmental pollution as well as unable to earn profit. Resource recovery and recycling could be a good option to reduce waste and earn profit from recyclable materials. Besides this aerobic composting, vermicomposting, anaerobic composting etc. could be useful to produce bio-fertilizer and bio-gas. By selling bio-fertilizer and biogas city could also earn profit. Integrated waste management consisting recycling and composting would be better solution for managing waste in the city.

Key words: Municipal solid waste, profitable, management, Mymensingh city.

Introduction

Rapid urbanization and population explosion in Bangladesh has led to the migration of people from villages to cities, which generate thousands tons of municipal solid waste (MSW) daily. The amount of MSW is expected to increase significantly in the near future as the country strives to attain a middle income developing nation status. Poor collection and inadequate transportation are responsible for the accumulation of MSW at every nook and corner (Sharholy et al., 2008). Mymensingh which recently upgraded as City Corporation have an area of 91.315 square kilometers having a huge population of 471,858 in 2018. Population migration rate in newly formed Mymensingh city is also high-flying. As the population is increasing in this city waste production is also increasing day by day. But, the management of MSW is going through a critical phase, due to the unavailability of suitable facilities to treat and dispose of the larger amount of MSW generated daily in Mymensingh city. Generally, MSW is disposed of in low-lying areas without taking any precautions or operational controls. Therefore, MSW management is one of the major environmental problems of Mymensingh. A great attentions should be paid in generation, storage, collection, transfer and transport, processing and disposal of solid wastes (Sharholy et al. 2008). But, in Mymensingh city, the MSW management system comprises only four activities, i.e., waste generation, collection, transportation, and disposal. The management of MSW requires proper infrastructure, maintenance and upgrade for all activities. This becomes increasingly expensive and complex due to the continuous and unplanned growth of the city. Previous studies regarding waste management in Mymensingh focused mainly on waste generation, current management practice, and its impacts on human and environment etc. (Rahman et al., 2015; Muhit et al., 2011; Mian et al., 2010; Islam et al., 2008), but not showing profit earning opportunities. Therefore, a study which shows the profit earning opportunities from waste management in Mymensingh city is essential. Considering the above phenomenon the preset study was designed to find out the profitable options for MSW management of Mymensingh city.
