“…The upsurge in the world's residents has resulted in enormous municipal solid waste (MSW) being generated. There are approximately 2.01 billion metric tons of MSW produced annually in the global community, which are projected to double in 2050, raising concerns in the future (Gautam and Agrawal, 2021). MSW is one of the world's biggest problems and is getting worse in developing and underdeveloped countries.…”

This study aims to learn the thematic evolution of Municipal Solid Waste Management research by revising Scopus indexed publications between 2001 and 2020. Within a longitudinal system, a scientific co-word inspection is conducted from 2001 to 2020. The publication series was split into two periods; the first period is from 2001 to 2010, and the second period is from 2011 to 2020. The findings, impact rates, and Municipal Solid Waste Management research’s conceptual growth are verified. In this emerging field of research, the co-word review established three key topic areas which are “Landfill”, “Urban Area”, and “Uncertainty”. The themes “Municipal Solid Waste,” “Waste Disposal,” “Costs,” “Waste to Energy” and “Environmental Impact Assessment” have changed from the first themes. The themes “Waste Management Systems,” “Treatment Technologies” and “Leachate” were found to have newly emerged and indicated that MSWM had been varied over successive periods. Future researchers could use this information to recognise the focus of awareness and make verdicts in various ways. There are a few limits of this study: 1) some of the Municipal Solid Waste Management publications may not have been included; 2) this study only considered publication records from the Scopus database, and 3) accordingly, the subject area may have changed if other new databases such as Google Scholar, Microsoft academics, or Dimensions have been retrieved. This study’s findings should be conceded as one proof-based structure for building future studies that benefit researchers, practitioners, and policymakers.

“…Due to increasing population, rise in economic development, and rapid urbanization, resource consumption has intensified, and an increase in the global waste generation rate has been observed [ 1 ]. Hence, environmental issues associated with waste management are raising serious concerns [ 2 ]. Sustainable management of municipal solid waste (MSW) is one of the major challenges responsible authorities face in developing countries [ 3 , 4 , 5 ].…”

Open disposal is the most common technique used for municipal solid waste (MSW) management due to the absence of sanitary landfills in Pakistan. The major cities and small towns in Pakistan have become a showcase of negligence and mismanagement of MSW, which results in deterioration of the environmental and social-life quality. Moreover, research has proved that inefficient handling (disposal) of MSW results in uncontrolled emissions of greenhouse gases (GHGs), mainly methane, and adds a significant share in global climate change. This study aims to estimate methane emissions from MSW disposed of at dumpsites and compare the GHG mitigation potential of different landfill strategies in specific climate and waste compositions in Karachi. The GHG estimations are based on lab-scale investigations conducted by simulating landfill conditions through the landfill simulation reactor (LSR) experiment. The synthetic MSW sample representing the composition of MSW generated in Karachi was used in the LSR experiment. Environmental sustainability and GHG mitigation potential of different landfilling strategies was evaluated by analyzing gas formation potential (GP21) and respiration activity (RI4) at the end of the experiment. This study revealed that the quantity of solid waste annually disposed of at dumpsites in Karachi possesses the potential to release about 3.9 Mt CO2-eq. methane (with specific methane potential of 1.8 tCO2-eq./tonne DM disposed) due to the biological decomposition of the organic fraction. Results show that the fresh waste disposed of at landfill sites in Karachi possesses about 92% and 94% higher GP21 and RI4, respectively, than the German allocated criteria for mechanically and biologically treated (MBT) waste for landfills Furthermore, sanitary landfills with post-aeration conditions showed higher GHG mitigation potential and low biological activity in the waste. The second highest GHG mitigation potential and lowest biological activity of the waste was noticed from bioreactor landfills with post-aeration conditions. The third number in GHG mitigation and reduced waste activity was noticed in the waste sampled from bioreactors without aftercare approach. The least GHG mitigation potential was noticed from the uncontrolled waste dumping (existing) approach with high residual gas potential and respiration index level. This lab-scale landfill simulation study can provide baseline data for further research and planning the development of new sustainable landfills in Karachi, Pakistan and in the region.

In the automotive and aerospace industry, abrasive products lodge the major portion of the machining applications. Among that, the coated abrasive disc is used for a finishing application. Once the disc is fully consumed, the disc is unused and considered waste. The present work focuses on removing phenol-formaldehyde resin coating, and the fiber backing is reused for the same coated abrasive disc production application as flexible fiber backing. A sandblasting technique removes phenol-formaldehyde resin coating and embedded abrasive grains. During the fiber backing recovery process, the experimental parameters such as abrasive pressure, abrasive type, abrasive size, and orientation of the disc are varied to find out the optimal surface roughness value for reusing the produced coated abrasive discs. The results highlight that the recovered backing has an abrasive size of 120 mesh pressure of 0.20 MPa, an abrasive type of garnet, and a standoff distance of 1 mm. Surface features such as surface roughness and micrographs of the eroded surface are analyzed. Finally, the recovered backing was reused in the coated abrasive disc production, and the performance of the recovered disc was compared with the standard discs. The recovered fiber backing disc product was similar to a standard fresh disc.
