Detection and extinguishment approaches for municipal solid waste landfill fires: A mini review.

Municipal solid waste (MSW) management is getting more attention in the present scenario. Even though various technologies like incineration, gasification, pyrolysis and waste-to-energy plants have been developed, landfills are still the major disposal option for MSW management. MSW at landfill creates issues that are highlighted at a global level like the fire at Deonar dumping site in Mumbai, India was visible and captured by the space satellites, leading to environmental pollution.

Mask consumption and biomedical waste generation rate during Covid-19 pandemic: A case study of central India.

The rapid generation of biomedical waste (BMW) due to covid-19 pandemic has created burden on the existing municipal solid waste management (MSWM) system in both developed and developing countries. The substantial influx of covid patients in Maharashtra, India has influenced the pattern of BMW generation, especially for the yellow category of BMW and incineration facilities. The objective of the study was to estimate the daily face mask consumption (D) and BMW generation from May 2020 to August 2021 in Maharashtra, India.

Estimation of spontaneous waste ignition time for prevention and control of landfill fire.

Openmunicipal solid waste(MSW) dumpsites in India are significant hotspots of spontaneous fire and associated air and ground water pollution. Unscientific dumping of MSW poses a major threat to the surrounding environment and human health. One-year-old biodegradable waste components comprised of paper, cardboard, newspaper, textile, wood, grass leaves and coconut shell were analyzed for the determination of the moisture content (MC), smoldering temperature, ignition temperature, and ignition time.

Determination of landfill gas generation potential from lignocellulose biomass contents of municipal solid waste.

The presence of heat, methane (CH) and oxygen in landfill sub-surface causes initiation of spontaneous waste ignition posing severe environmental impacts. A municipal solid waste (MSW) reactor (trough) was designed to monitor landfill gases (LFGs) i.e.

Specific heat and thermal conductivity of municipal solid waste and its effect on landfill fires.

Municipal Solid Waste (MSW) landfills are sources of physical, chemical and microbiological processes and as a result, gases and heat are generated as by-products. The generated heat flows from the higher to lower temperature regions within the landfill. Specific heat and thermal conductivities are two important properties that determine heat flow in MSW landfills.

Estimation of heat generation and consequent temperature rise from nutrients like carbohydrates, proteins and fats in municipal solid waste landfills in India.

The heat generation and temperature rise due to the anaerobic degradation of municipal solid waste (MSW) for selected landfills across India have been estimated in this paper. MSW was quantitatively characterized into carbohydrates, proteins, fats using landfill degradation and transport (LDAT) model equations' and the physical composition of MSW. The heat released due to the breakdown of per kg of carbohydrates, proteins, fats were calculated using chemical equations involved in the anaerobic degradation process.

Determination of ignition temperature of municipal solid waste for understanding surface and sub-surface landfill fire.

Open dumping of municipal solid waste (MSW) is a common practice in India which leads to a number of problems like non-uniform compaction, slope failure, percolation of water during rainy seasons, abrupt leachate generation and stability issues. It also leads to various other issues, such as manual scavenging and deliberate waste burning. During the waste degradation process, an enormous amount of heat and landfill gases (LFGs) like carbon dioxide (CO) and methane (CH) are generated.
