“…The absence of a proper waste planning or monitoring unit is a possible hindrance to strategic and efficient SWM planning. Proper management of solid waste in the city would be encouraged by the informed development and implementation of an effective integrated solid waste management (ISWM) plan that closely follows the waste management hierarchy observing the 3Rs ( r educe, r euse, and r ecycle) or in the case of economically challenged countries such as Zimbabwe, the 3Ss ( s anitation, s ubsistence economy, and s ustainable landfilling) of sustainability (Lavagnolo and Grossule, 2018; Mandevere and Jerie, 2018). However, presently, the country’s HSW management strategies do not seem to be prioritizing sanitation and creating a subsistence economy.…”

A mini-review on household solid waste management systems in low-income developing countries: A case study of urban Harare City, Zimbabwe

Among other African cities, in terms of solid waste management (SWM), Harare has been ranked as one of the poorest. The municipality struggles to efficiently provide SWM services to its residents. Considering that SWM systems are complex, the individual behaviour of its components (waste generation, collection, and disposal) determines the overall performance of the system. This mini-review thus aims to understand the management system of the urban city’s biggest source of solid waste which is household solid waste (HSW). The systematic literature review methodology using NVIVO was used to analyse the literature. Out of a selected sample size of 500 journal articles, 26 were selected based on their relevance to the study. The uncertainty of the data provided by the Harare City Council (HCC) and of HSW generation data harvested in the literature was calculated. According to the HCC data records, Harare has an average daily waste generation per capita of on average 0.38±0.1 kg producing about 207, 635, 294±56, 027, 040 kg of HSW generated annually. With the waste collection efficiency in Harare at about 72.4%±7.5%, the city collects approximately 170, 385, 600±33 384 209 kg of HSW annually. All the collected HSW is disposed of in the city’s major MSW dumpsite called Pomona and only about 23, 498, 400±3, 988, 817 kg MSW is recovered annually with the average recovery efficiency at around 9.5%±2.8%, where most of the waste recovery is done by the waste pickers.

“…The per capita waste generation is about 400 g/day but the solid waste management system is not well implemented due to limited finances and organizational capacity. Moreover the perception of people on pollution and waste impacts is quite low as in the most of the developing countries (Lavagnolo, 2019).…”

“…This approach relies on the increased air-water interface with the small droplets in the mist to promote volatilization. If effective, use of such a system to promote ammonia volatilization would be advantageous, particularly in developing countries (Lavagnolo and Grossule, 2018). However, little work investigating the efficacy of such a system has been reported in the peer reviewed or gray literature.…”

The Three Rivers Solid Waste Authority (TRSWA) operates a MSW landfill outside Jackson, South Carolina (USA) at which leachate ammonia concentrations are of concern. The landfill operates a droplet spraying/misting system (known as the Lilypad system) in their pond to enhance both leachate evaporation and, possibly, ammonia volatilization. The overall goals of this study were to determine the fate of nitrogen in the pond and to ultimately quantify the role the Lilypad system plays in enhancing ammonia removal. To accomplish the study goals, an empirical model based on collected leachate and mist samples, climatological data, and pond hydraulic data was developed to quantify the extent of ammonia volatilization, nitrification, and denitrification that occurred in the pond over the study period. Results from this work indicate that volatilization, nitrification, and denitrification were occurring in the pond, with volatilization of ammonia-nitrogen accounting for the majority of nitrogen removed from the pond. Results also indicate that the Lilypad system has the capability to significantly enhance the volatilization process.
