“…If organic waste can be managed at the household level, it would drastically decrease waste generation. The high volume of waste generation, lack of collection space, and the presence of dump sites Khanal (2023) https://www.malque.pub/ojs/index.php/msj Per/capita/day cause serious health risks (De and Debnath 2016;Rana et al 2017;Chikaire et al 2022).

There is lack of study predicting the Municipal Solid Waste (MSW) output scientifically and accurately for least developed countries like Nepal. Previous studies have primarily relied on the tentative amount of waste generation linked with the number of vehicles involved in waste collection and transfer to the landfill site. This study used linear regression analysis to forecast the solid waste generation of Kathmandu Metropolitan City (KMC) by undertaking past population data and solid waste generation.. The SPSS analysis resulted in a strong relationship between population and solid waste generation with a coefficient of 0.956. A linear regression validation was performed to ensure that the derived formula is statistically significant. The finding indicates the r squared (R2) value to be 0.913, leading the waste prediction model to be very strong. The prediction equation of 0.659X - 204222.952 resulted in an average waste generation of KMC as 1006 t/d on average till 2035 with an average per capita/d waste generation of 0.54 kg. The current MSW generation of KMC is found to be 766 t/d and predicted to reach 1259 t by 2035. The information can be helpful for the municipality and urban planning authorities to make strategies for effective management of waste generated in KMC, creating less burden at the Banchare Danda landfill site.

In Nepal, the informal sector is responsible for treating 15% of household waste. It is the only alternative to landfilling and open disposal; however, the current waste management system does not acknowledge informal recyclers aggravating various challenges and vulnerabilities that the sector already faces. This study identifies and validates for the first time the challenges of the informal waste sector while providing a granular understanding of the actors that shape waste management in the region. The study uses primary data collected over a period of 6 months in Kathmandu and Lalitpur, the first and third most populated areas in Nepal. The methods considered were semi-structured interviews, questionnaires, and a co-creation workshop with formal and informal actors. A novel characterization of waste management actors was conducted to identify two profiles namely cyclists and scavengers and question the formality of the collection centres. Findings suggest that the price volatility of recycled materials and the lack of treatment and absence of regulatory capacity are among the main challenges in promoting a circular economy from the informal sector. The recommendations to overcome these challenges are a series of policy reforms, such as an extended responsibility producer scheme and the review of the tax on recycled material transport. The main policy implication from the finding reveals that circular economy is already being promoted by the informal sector — a responsibility that should fall under the remit of the regional and national governments. The study concludes that integration is not only necessary to improve the conditions of informal workers but essential to developing a circular economy in Nepal.

The production of electronic waste (e-waste) has reached alarming levels globally, posing significant environmental, economic, and health risks. This review paper comprehensively analyzes the challenges, impacts, and potential solutions associated with e-waste management in developing nations. It highlights the urgent need for proper regulations, infrastructure development, and public awareness to address the growing problem of e-waste. The paper identifies gaps in current research, such as the lack of concrete recommendations and practical solutions, and aims to provide a foundation for future studies to propose strategies for improving e-waste management practices. The findings emphasize the environmental effects of e-waste and the negative consequences on disadvantaged communities, particularly in underdeveloped regions. Furthermore, the review highlights the importance of transitioning to a circular economy and the economic opportunities presented by e-waste, which contains valuable metals that can be recovered and recycled. The paper calls for the formulation of specific policies focusing on the 3Rs (Reduction, Reuse, and Recycle) and the implementation of provisions such as pollution taxes to reduce e-waste and promote responsible consumption. By addressing these challenges and offering sustainable solutions, effective e-waste management can mitigate environmental risks, protect human health, and contribute to a circular economy.
