Abstract

For over three decades, Bangladesh has been facing the challenges associated with urban waste management, most notably with regards to fecal sludge as well as solid waste. The volume of waste produced per day has increased steeply. In the year of 1991, urban regions produced approximately 6,493 tons of municipal solid waste each day. In 2005 this increased to 13,330 tons, and by 2014 it had increased to 23,688 tons per day. The growing urban population is a significant factor. The urban population, as of 1991, was approximately 21 million, and by 2005 it had increased to 33 million, with predictions expecting this to increase to 119 million by 2041. The concerning fact is that waste generation is outpacing population growth because each individual is producing an increasing amount of waste. The greatest portion of urban waste is organic. It was 77% of urban waste in 2014. By 2021 it reached almost 80%. This trend is consistent for both cities & pourashavas. This adds to the burden of already constrained landfill space. However, it also indicates that a great deal of the waste stream is organic and biodegradable. Rather than sending it all to landfills, it is necessary to find more productive uses for this waste. Research here considers the conversion of organic waste from food and crop production into bio-nano fertilizers. Such fertilizers could enhance nitrogen retention and improve crop production. The aim is to devise a practical approach where waste is treated as a resource instead of a liability. Organic waste-derived bio-nano fertilizers will alleviate landfill waste, diminish reliance on synthetic fertilizers, and foster climate-resilient agricultural practices in Bangladesh. Additionally, the approach advances a circular system where waste is transformed to enhance agriculture.
