“…Due to monsoon season in the month of July and August the highest moisture content in solid waste was observed. The similar finding of high moisture content in solid waste wasstated by Gupta et al, 2015 andChavan et al, 2019. While, the minimum value for moisture was found to be in administrative centre unit waste of CCSHAU and LUVAS campus that might be due to lowest fractionof food waste.…”

Effective management strategy is required for handling the large quantities of waste produced by various societies/ organizations and waste characterization is essential to prepare this management policy. In this study, solid wastes collected from the combined campus of Chaudhary Charan Singh Haryana Agriculture University (CCSHAU) and Lala Lajpat Rai University of Veterinary and Animal Science (LUVAS), Hisar was characterized through population estimation, field investigations and applying ASTM D5231-92 standard method. In the combined campus, the average quantity of solid waste generation was found to be 1047.1Â±214.4 kg/day. The whole campus was divided into five structural units and waste composition was determined, mixture unit waste comprised the highest fraction of food 62.13% and polythene 10.8%. The statistical estimation obtained a strong positive correlation of mixture unit waste with residential and markets waste contents, which was 0.995 and 0.997 at p<0.01. The analysis of solid samples showed that the biodegradable part of solid waste may be a better source for composting while some content of non-biodegradable waste can be sold into the market for recycle or reuse purpose. On the basis of solid waste characterization, a set of recommendations were suggested to strengthen the waste management processes for institutions.

“…Surface fire spreads outside the landfill area but is relatively easy to extinguish. Cavity fires are a form of combustion (pyrolysis) where the thermal reaction takes place under anoxic conditions deep below the landfill surface 77,88 . These are difficult to detect and may create large voids in the landfill, which can cause the landfill surface to cave in.…”

“…170 Besides, the moisture content of OSW might also be an impact factor. Chavan et al 171 collected both the fresh and old wastes from an open dumpsite to determine their ignition temperatures. Results showed that the old waste had a lower ignition temperature than the fresh waste, mainly because of its smaller moisture content.…”

Increasing economy and population result in the rapid growth of solid waste in China, with more than 70% being carbonaceous components. The generated carbon-bearing solid waste is called as organic solid waste (OSW). In this Review, OSWs from both municipal and industrial sources are discussed and divided into municipal solid waste (MSW), organic sludge, polymer solid waste, and biomass-like solid waste, according to their variations in origins and characteristics in China. Agricultural waste (i.e., biomass) and large-scale industrial solid waste (e.g., coal waste) are not considered, because of their well-established fundamentals. Incineration is becoming the most common method of energy recovery for OSW in China, while it has to face the problems of relatively low thermal efficiency, high air pollutant emission, and the high risk of fly ash products. Compared with MSW incinerators, coal-fired power plants own efficient power generation systems and centralized air pollution control devices (APCDs). With the fact that mixed coals are widely used in existing power plants, it is of great significance to study and discuss the current status of cocombustion of OSW and coal in China. In this work, the physicochemical properties of OSW were first introduced, with a subsequent detailed summary on their co-combustion fundamentals, such as devolatilization, ignition, char reactivity, and combustion efficiency, and ash-related issues, including fouling/slagging, high-temperature corrosion, and leaching behavior of ash residue. Furthermore, pollutants emissions regarding conventional pollutant [CO, SO 2 , NO x , HCl, particulate matters (PM)], heavy metals, and hazardous organic pollutants such as polycyclic aromatic hydrocarbons (PAHs) and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) were analyzed. Some pretreatment methods to reduce the risk of co-combustion were also discussed, including pelletization, drying, torrefaction, hydrothermal carbonization, and low-temperature pyrolysis. Lastly, discussions and perspectives on the future co-combustion technology of OSW with coal were presented. This work aimed to gain systematic knowledge on the co-combustion technology of OSW and coal, providing guidelines for further applications of OSW in power plants in China, as well as other countries in the world.
